Educator’s Guide BEYOND PLANET EARTH the future of space exploration INSIDE Suggestions to Help You COME PREPARED • ESSENTIAL QUESTIONS for Student Inquiry • Strategies for TEACHING IN THE EXHIBITION • MAP of the Exhibition • ONLINE RESOURCES for the Classroom • Correlation to STANDARDS • GLOSSARY amnh.org/education/beyond essential QUESTIONS Ever since we first looked up at the night sky, space has captured our imagination. This exhibition is a journey across the solar system and into the future, from the first manned space mission to the colonization of Mars. Use the Essential Questions below to connect the exhibition’s themes to your curriculum. why explore space? As humans, we seek to understand our world. We inhabit every continent, have planted flags at the Poles, and descended into deep ocean trenches. Looking beyond Earth, the potential for new discoveries is tremendous, but many unknowns remain. Will space tourism become commonplace? How can we protect our planet from an asteroid impact? Is there life beyond Earth? Can we establish a research station on the Moon? Could we make Mars habitable for humans? how will we explore space? People first “explored” space with the naked eye, but they observed only a small fraction of what we now know exists. The telescope brought more things into view: smaller and more distant planets, dimmer stars. Hand-held telescopes gave way to larger ones like those atop Hawaii’s dormant Mauna Kea volcano, above much of the haze of the atmosphere. Telescopes like Hubble now orbit Earth, transmitting detailed images of the cosmos. Humans have walked on the Moon, and hundreds have lived and worked in the International Space Station. Unmanned spacecraft carry out missions too distant or dangerous for humans; the Voyager 1 and 2 space probes have even left our solar system. Soon, the James Webb Space Telescope will look further into space than ever before, connecting our Milky Way to the Big Bang. Commercial spacecraft will take thousands of people into space — even if only for a few minutes each! What’s next? Here are some possibilities, some closer to being realized than others: Nearer term: • establishing a semipermanent base on the Moon: scientists and explorers may live for weeks or months at a time in expandable modules along the rim of the South Pole’s Shackleton Crater. This visualization shows how Curiosity’s arm would examine rocks on Mars for signs of ancient life. • searching for life on Mars and Europa: scientists hope to find evidence of life beneath the Martian surface; robots may search the salty ocean of Jupiter’s moon Europa for extremophiles. • discovering exoplanets: researchers have already identified well over a thousand planets orbiting other stars, and many more such discoveries are certain. If some of these faraway worlds prove Earthlike, scientists will investigate them for evidence of life. Longer term: • building a lunar elevator: tethered to a space station, it could help transport goods and people between Earth and the Moon. • docking with asteroids: astronauts could mine space rocks for rare metals and deflect those that might collide with Earth. • terraforming Mars: one day, scientists and engineers will be able to transform the planet’s surface and atmosphere, making it habitable for our descendants. what are the challenges of space exploration? Earth’s atmosphere provides living organisms with breathable air and a temperate climate, and also shields us from dangerous radiation and most meteor impacts. Traveling and living beyond its protection presents massive challenges. To survive en route, we would need to bring our own air, food, and water; avoid debris; shield ourselves from high-energy radiation; and prevent the debilitating effects of long-term weightlessness. Extreme isolation and long confinements in small spaces could take a psychological toll, as could the possibility of never returning to Earth. Once at our destinations, supplies and spare parts would be severely limited, and the margin for error tiny. To protect future generations of astronauts, engineers are at work on innovations such as improved space suits and micrometeoroid shielding. Faster propulsion systems would reduce or eliminate many of these challenges — and put ever more distant destinations within our reach. GLOSSARY COME PREPARED asteroids: small rocky and metallic bodies, Plan your visit.

Meteors (“shooting stars”) are small pieces of asteroids or comets that enter Earth’s atmosphere, where most burn up. The few that land on Earth are called meteorites. exoplanets: planets that orbit stars other than our Sun extremophiles: organisms adapted to harsh environments, including extreme cold, dryness, radiation, darkness, and chemicals that would be toxic to most other organisms. Examples on Earth include bacteria in the cooling pools of nuclear reactors, in hydrothermal vents on the ocean floor, and in the dry valleys of Antarctica. hubble space telescope: a telescope launched in 1990 into low-Earth orbit, whose detailed images of cosmic objects have led to many important discoveries. Hubble’s cameras detect ultraviolet, visible, and infrared light. james webb space telescope: scheduled to launch in 2018 and designed primarily to detect infrared light, this large telescope will observe extremely distant objects — including the first stars and galaxies that formed in the universe. potentially hazardous object: any near-Earth asteroid or comet that is longer than 150 meters (500 feet) and that comes within 8 million kilometers (5 million miles) of Earth’s orbit rare earth metals: a group of metals that have many commercial uses but are expensive to mine on Earth shackleton crater: a crater near the Moon’s South Pole that contains ice. The rim, which has abundant sunlight, has been proposed as a possible location for a lunar base camp. terraform: the process of making another planet or moon more Earthlike Read the Essential Questions in this guide to see how themes in Beyond Planet Earth connect to your curriculum.

Starting with the Moon, our closest neighbor, and heading out across our solar system, this exhibition uses models, artifacts, videos, dioramas, and hands-on and computer interactives to immerse visitors in the high-stakes adventure of space exploration. The main sections of the exhibition represent different destinations in space. Have students explore each environment, and consider how scientists and engineers would approach the unique challenges that each presents. overview: The historic Apollo missions of the 1960s and ‘70s brought back rocks that taught us a great deal about the history of the Moon — and of Earth. Astronauts visited the surface of the Moon, but only for a few days at the most. The next step could be to establish a semi-permanent scientific research station. Have students imagine what it would be like to live and work in this desolate environment. Encourage them to look for their home planet in the sky. history of space exploration As you enter, examine some artifacts of manned and unmanned space voyages, which include models of Sputnik and a Mars Rover, and a diorama depicting the final Hubble Space Telescope upgrade. Have students watch the six-minute film in the theater, and then discuss which destinations they find the most intriguing. • Lunar Elevator Model: Held in place by gravity, this solarpowered elevator would travel between a space station and the Moon. Ask the class to consider the advantages of an elevator over a rocket. (Answers may include: Launching rockets from Earth or the Moon is expensive. And if we ever had a base on the Moon, we’d have to do that an awful lot to get materials to and from the Moon and back to Earth. While building a lunar elevator would be really expensive at first, it might prove less pricey in the longterm, since it would use little power once built.) Have students find information that helps them imagine what a trip on this “space elevator” might be like. challenges & approaches: • Base Camp, Moon’s South Pole: Have students explore this lunar crater and consider why scientists think the rim would be a suitable location for a base camp. Ask what hazards astronauts would face on the surface of the Moon, and how they could protect themselves. (Answers may include: The expandable spacecraft would shelter astronauts from solar radiation and meteoroid barrages, keep them warm, and provide air to compensate for the Moon’s lack of atmosphere.) • Liquid Mirror Telescope Interactive: Ask students what problems astronomers confront when using tele-scopes on Earth’s surface. (Answers may include: haze of the atmosphere, rain clouds, light pollution) What makes conditions on the Moon more favorable for astronomy? (Answers may include: On the Moon, there is no atmosphere to obstruct visibility, and no wind or weather to affect telescopes.) This liquid mirror telescope, the largest on Earth, is 6 meters (20 feet) across. On the Moon, undisturbed by wind or weather, the surface could be larger than a football field. overview: Most asteroids orbit between Mars and overview: Mars is more likely to harbor life than any Jupiter, but some cross Earth’s orbit. Collisions are rare but can be devastating, so scientists are developing technologies to deflect near-Earth asteroids (NEAs). Some asteroids may also contain rare Earth and other valuable metals. other known planet. Features like immense dry riverbeds hint at an ancient environment that could have supported life — and still might, if liquid water exists below the surface. Orbiters have mapped the entire Red Planet, rovers and probes have studied the surface in detail, but no humans have traveled there. Some scientists wonder whether, in the distant future, we might make this dusty planet habitable for humans. challenges & approaches: This is an a illustration of a possible system for anchoring to the surface of an asteroid. challenges & approaches: • Itokawa Model: Invite students to examine a model of this NEA and the robotic Japanese spacecraft that docked with it. Ask them to think about what it would be like to study an object that has so little gravity that they couldn’t stand on it. (Answers may include: Although Itokawa is 1770 feet (540 meters) long, it is too small for a spacecraft to orbit. The craft would have to hover over the asteroid, and astronauts would have to tether themselves to its surface in some way.) • Potentially Hazardous NEAs: Suggest that students use the interactive kiosk to explore different ways to alter an asteroid’s course. If an object looks like it might collide with Earth, what could we do about it? (Answers may include: An atomic bomb might seem like the best, but actually bombing an asteroid could make things worse by breaking up the space rock into lots of pieces that then would all impact Earth. There are other options like a “gravity tractor,” which is a spacecraft that would use its gravity to pull the asteroid off course over a long period of time.) • Getting There and Daily Life: On the outbound journey, astronauts might spend six to nine months in very tight quarters, coping with the effects of weightlessness and solar radiation. Have students explore this section to see how people could stay safe and healthy (and keep stuff from floating away). (Student observations may include: Our bones and muscles are used to fighting gravity, and exercise is essential to keep them strong in space. Spinning compartments for sleeping would generate artificial gravity and help prevent bone loss and other health problems. Shielding and emergency shelters would protect astronauts from deadly solar radiation.) • Have them take the Mars Personality Test to see if they have what it would take to reach the Red Planet and live and work there. (Student observations may include: Traveling to Mars would mean sharing a small space with other people for many months, which requires patience, an easy-going temperament, and a sense of humor. Astronauts would also need to be able to follow detailed instructions and make quick, independent decisions.) • Mars Explorer and Mars Environment: Have students use the interactive to examine the surface of Mars. Ask what features they observe that Mars shares with Earth. (Answers may include: Like Earth, Mars has volcanoes, canyons, polar ice caps, and many places where liquid water once flowed on the surface.) In what ways are the two planets very different? (Answers may include: The surface of Mars is dry and barren, and has no liquid water.) • Curiosity Mars Rover: The primary mission of this roving science lab is to search for signs of habitable environments. Ask students what kinds of tools Curiosity carries, and what they measure. (Answers may include: The one-ton robot is packed with tools, including 3-D cameras that rotate in every direction; a laser beam that vaporizes rock samples for analysis; a robotic arm that analyzes rocks, digs holes, and scoops up samples; and a weather station that monitors wind, temperature, humidity, and air pressure.) • Terraforming Table: Explain that terraforming is the process of making a planet more Earthlike so that it could become habitable for humans. Ask students to investigate how to turn this cold and barren planet into a wet, warm, fertile world. (Answers may include: Terraforming would involve many stages, such as adding heat to release frozen water and carbon dioxide to trigger the greenhouse effect that keeps Earth warm; inserting life (hardy lichens, algae, and bacteria first) that would begin building soil and enriching the atmosphere; releasing liquid water; and making an oxygen-rich atmosphere.) overview: The giant planets of the outer solar system — Jupiter, Saturn, Uranus, Neptune — together have more than 160 moons. One of Jupiter’s moons, Europa, intrigues scientists because they think it may have a deep saltwater ocean that could contain life. challenges & approaches: • Europa Theater and Model of Submersible: Ask students to think about this moon’s unique environment. Have students watch the six-minute movie and reflect on how this mission would compare to journeys to Mars or the Moon. (Answers may include: Robots may someday search for life in Europa’s ocean, but such a mission is probably decades away. A manned voyage would be even farther in the future because Europa is so far away — a 17-year trip by Apollo spacecraft.) An enhanced color photograph of Europa’s cracked ice surface. beyond: All the places that your class has explored so far belong to our own solar system. But scientists have already found evidence of over 1,000 other solar systems — stars with planets orbiting them — in our Milky Way galaxy alone. How many more remain to be discovered? As students experience the holographic representation, ask them to think about other worlds we may explore someday. What do they imagine we might find? These illustrations show how, over hundreds or even thousands of years, Mars might be transformed from a frigid, barren planet into a warm and fertile one like Earth. online RESOURCES our moon sciencebulletins.amnh.org/?sid=a.v.moon.20061004 This visualization shows how a violent collision could have given birth to our Moon in just one month. journey into space: gravity, orbits, and collisions teacher.scholastic.com/activities/explorations/space This interactive introduces students to the ways in which gravity shapes the universe. geologists on mars sciencebulletins.amnh.org/?sid=a.f.mars.20040401 This 8-minute video describes the 2004 Mars Exploration Rover mission that found evidence of liquid water. nasa: exploration nasa.gov/exploration Feature stories about missions, discoveries, and other initiatives describe the next era of space exploration. impact! tracking near-earth asteroids sciencebulletins.amnh.org/?sid=a.f.nea.20050504 This 7-minute video explores the risks of an asteroid hitting Earth, and how astronomers track the orbits of near-Earth objects. planetary mysteries amnh.org/ology/planetology Learn how scientists study our solar system, and about some of the big questions that remain unanswered. space travel guide amnh.org/ology/spacetravel This drawing and storytelling activity helps kids combine fact and fantasy on a trip to outer space. a closer look at mars amnh.org/ology/closer_look_mars Kids help reporter Stella Stardust learn more about Earth’s closest neighbor. are you cut out for mars? amnh.org/ology/mars_quiz Kids can take this quiz to see if they’re up for the challenge. in pictures: beyond planet earth amnh.org/ology/inpics_beyond This photo gallery illustrates some of the places in our solar system that humans might someday explore. nasa: for students nasa.gov/audience/forstudents This NASA portal offers current science content, activities, events, images, podcasts, educational video segments, and more. google earth google.com/earth Now you can use Google Earth to view stars, constellations, and galaxies, as well as the surfaces of Mars and the Moon. DID YOU KNOW? When you’re in space, the sky looks black because there’s no air for visible light to bounce off of. Space is silent. We hear because of pressure waves in the air, and there’s no air in space. Everything in the universe — planets, asteroids, and even black holes — gives off light. But almost all of it is at wavelengths that our eyes cannot see. The light that we see from stars has taken years — typically millions and sometimes billions of years — to reach us. For example, if a star 100 million light years away exploded today, people on Earth wouldn’t see the explosion for 100 million years.

DOING SCIENCE in space Science in space involves extraordinary challenges. Here are some of the questions scientists are asking, and some of the technologies that are enabling them to travel farther more safely, and to gather evidence from places too dangerous — or still too distant — for humans to visit. how can scientists investigate space first hand? how do we look for evidence of life on mars? Today’s bulky, heavy suits surround astronauts with pressurized air. This sleek new spacesuit applies pressure directly to the skin by wrapping the body tightly in several layers of stretchy, very tough, spandex and nylon. This makes the suit lighter, safer because it won’t lose pressure if punctured or torn, and easier to move and work in. A one-ton science lab, the Curiosity rover will land on Mars inside Gale Crater, which is thought to have once been a lake. The rover will make its way to the top, studying each layer of sediment in order to obtain a cross-section of the crater’s history when it was wet, and possibly home to living things. Curiosity can pick up samples and test them onboard, fire a laser at objects to see what they’re made of, and it even contains a small weather station. how do we travel further and stay longer? The Nautilus-X spacecraft could carry a crew of nine on a two-year voyage — long enough to reach Mars. It would contain exercise machines, so astronauts could keep their muscles and bones strong. Spinning compartments for sleeping would also prevent bone loss and other health problems by generating artificial gravity. Solid waste from toilets could be used as compost for plants that in turn would provide food and oxygen. how can we see further into space and back in time? A liquid mirror telescope at the Moon’s South Pole could detect infrared light from the earliest days of the universe, some 13.7 billion years ago. Larger than a football field, the telescope would have a main mirror made of a slowly spinning, highly reflective liquid. A rotating dish naturally forms a parabolic shape, which focuses light from diffuse sources such as incoming starlight. With no interference from wind or weather, this surface would be so smooth it looks solid. Once spinning on electromagnetic bearings, the telescope would need little maintenance. © 2011 American Museum of Natural History. All rights reserved. BEYOND PLANET EARTH the future of space exploration Activities for Grades K–2 Objects in the Sky: Lunar Observations overview NYS Science Core Curriculum Students will use their senses to make observations about the Moon and to think about what it might be like to visit and live there. PS 1.1a: The appearance of the Moon changing as it moves in a path around Earth to complete a single cycle. background for educator The Moon is Earth’s only known natural satellite. The Moon can be visible during a bright day because it’s relatively close to Earth and it reflects sunlight. At this age level, students should make observations about the day and the night sky. For additional information about the Moon, go to: • amnh.org/exhibitions/permanent/meteorites/impacts/moon.php • science.nasa.gov/science-news/science-at-nasa/2006/30jan_smellofmoondust/ before your visit In these activities, students will practice observing the Moon by looking up in the sky or at photographs. They will discover that the Moon changes a little bit from day to day, and that the pattern repeats about every four weeks. Activity: Where Was the Moon on Your Birthday? Ask students to describe, draw, or play-act what the Moon can look like. Have students share their ideas. Ask students: What do you think the Moon looked like on the day you were born? (Answers will vary.) Then go to the Moon Phase Images website (tycho.usno.navy.mil/vphase.html) and enter each student’s birth date to see what the Moon looked like that day. (Or, you may wish to print out each birthday image prior to class.) Have students describe the shape of the Moon on their birthdays, and to record it in a drawing. Use their drawings to guide a discussion about how the Moon’s appearance changes. Plan how your students will explore Beyond Planet Earth using the Group Worksheets. Students should work in groups of three to four, each facilitated by a teacher/parent chaperone as they explore the exhibition. If possible, distribute copies of the worksheets to chaperones beforehand, and review them to make sure everyone understands the activities. Activity: Luna Stories Read a story about the Moon to your students. (See the booklist for recommendations.) Then ask them to draw and share what they learned from the story. during your visit Beyond Planet Earth: The Future of Space Exploration 3rd floor (45 minutes) In the Introduction and Moon sections of the exhibition, students will use their senses to continue to learn about the Moon, and to begin to investigate some of the ideas scientists have about traveling there. Have the adult chaperones use the Group Worksheets to guide their students to make observations of the Moon and to record students’ ideas of what it’s like there. Remind the chaperones to encourage students to use their words to describe what they see, feel, smell, and think. Also have students make a drawing of the Moon landscape and let them choose something else in the exhibition to draw. © 2011 American Museum of Natural History. All rights reserved. amnh.org/beyond BEYOND PLANET EARTH the future of space exploration Activities for Grades K–2 Rose Center for Earth and Space 1st floor (15 minutes) Have students observe the metal Moon globe and Moon rock (located in the area between the Gottesman Hall of Planet Earth and the Heilbrunn Cosmic Pathway), as well as photographs of the Apollo Mission (located in the hallways surrounding the Rose Center). As they study these items, ask students to make observations and inferences about the surface of the Moon. Ask: What do you notice? (Answers may include: There are lots of craters, craters within craters, some smooth sections.) On the Moon globe, point out the far and near sides of the Moon. Ask students if they know which side is visible from Earth. back in the classroom Activity: Sharing Moon Observations & Findings Have students draw the Moon and post their drawings. List the five senses on the board and have students share what they’ve learned about the Moon by using their senses. (Answers may include: The smell of the Moon rocks; the texture of the Moon: smooth in some places, lots of craters, the lunar surface feels rough; there are no trees or houses or animals on the Moon; the Earth looks small from the Moon.) Activity: Luna Cartoons Ask students to draw on what they learned during the trip to make a short cartoon about two kids going on the lunar elevator. What would they talk about on the way up? How would it feel? What would they see when they arrived? (Answers will vary.) Activity: Moon Watch Flip book amnh.org/ology/moon_flipbook Use this activity to continue observing the Moon in the sky. Make observations for a month, and post observations and drawings on a calendar in the classroom. recommended books If You Decide to Go to the Moon Written by Faith McNulty and illustrated by Steven Kellogg “If you decide to go to the Moon in your own rocket ship, read this book before you start.” This book is a beautiful guide for a kid ready to take a fantasy trip into space.

All rights reserved. amnh.org/beyond BEYOND PLANET EARTH the future of space exploration Activities for Grades 3–5 Modeling the Solar System overview NYS Science Core Curriculum Students will investigate a model of our solar system that will help them contextualize the content of the exhibition. Students will then generate questions about space exploration to investigate in the exhibition, and share their findings upon their return. The activities culminate with sharing what they have learned and writing an imaginative story about travelling in space. PS 1.1c: The Sun and the planets that revolve around it are the major bodies in the solar system. background for educator The distances in our solar system are vast and the planets comparatively tiny, so models are vital tools for understanding how planets are placed in space. They’re also useful for visualizing how the planets move in relation to each other, since from our vantage point on Earth we can’t see all of the planets around us. before your visit Discussion: Structure of the Solar System Review with students the structure of the solar system. Ask them: • What is at the center of the solar system? (Answer: The Sun, our star, is at the center of the Solar System.) • What types of planets are there, and where are they found? (Answer: There are four inner, rocky planets that orbit closest to the Sun: Mercury, Venus, Earth, and Mars. Beyond the Asteroid Belt, the four outer, gas giant planets are Jupiter, Saturn, Uranus, and Neptune. The Kuiper Belt contains Pluto and other small icy objects. This area of the solar system begins just inside Neptune’s orbit and extends well beyond it.) Plan how your students will explore Beyond Planet Earth using the student worksheets. Divide your class into two teams: Moon Explorers and Mars Explorers. You may wish to have students explore the exhibition in pairs. Prior to your visit, students will have already begun the exhibition worksheets; make sure they bring their worksheets to the Museum. • Describe how the planets move around the Sun. What are their orbits shaped like? Do they all move at the same speed? (Answer: Planets revolve around the Sun in nested, nearly circular orbits. The closer an object is to the Sun, the faster it revolves.) • Where in the solar system, besides the Earth, have human beings traveled? Where have we sent robots/spacecraft? (Answers may include: Humans have walked on the Moon, and robotic rovers have explored Mars. Unmanned spacecraft have also visited the Moon and Mars, as well as planets and moons in the outer solar system. The Voyager 1 and 2 spacecraft have traveled beyond the orbit of Neptune and continue beyond our solar system.) Activity: Earth as a Peppercorn: noao.edu/education/peppercorn/pcmain.html Use the online lesson plan at to have students create a scale model of the solar sstem that is accurate both in the planet size and interplanetary distance. Optional Extension Activity: Moving Solar System Model: kepler.nasa.gov/files/mws/HumanOrrerySSSmsGEMS.pdf Use this lesson plan to create a moving model of relative planet speed. Preparation for the Investigation in the Beyond Planet Earth Exhibition From what students know about planets and space, along with what they observed in their models of the solar system, have them think about the challenges that humans would face in travelling to and living on another planet. Tell students that humans are most likely to return to the Moon and to visit Mars before they travel to other places in the solar system. Divide the class into two teams: Moon Explorers or Mars Explorers. Using the Student Worksheet, have each team complete columns 1 and 2, charting what students know about the Moon or Mars, (depending on the team). Have them write down any questions that come up about traveling to or living on a heavenly body other than Earth. (This can also be done as a class or in small groups.) They will complete column 3 in the exhibit and after they return. © 2011 American Museum of Natural History.

Have students walk through the exhibition in pairs or small groups and think about the questions they raised on columns 1 and 2 of their charts prior to their visit, focusing on either the Moon or Mars section. As they find relevant information in the exhibition, have them write it in column 3. You may wish to use the “Teaching in the Exhibition” section of the Educator’s Guide to help your students identify challenges and approaches to travelling and living in space. Scales of the Universe 1st floor (30 minutes) In the Rose Center for Earth and Space, students will be using the Hayden Sphere and the walkway around it to investigate relative sizes of celestial objects. First walk around the sphere (with the glass windows on your right) to the area that displays the planet models. (Some of the planets are suspended above you, while others are mounted on the railing.) Draw students’ attention to all eight planet models. Remind students that the 87-foot sphere represents the size of the Sun. Ask students to observe the planets’ sizes relative to it. Remind them of the sizes of the planets in the “Earth as a Peppercorn” model that they built at school; ask them to imagine how large a model on this scale would be if the planets were placed at the correct distance from the Hayden Sphere. back in the classroom Wrap-Up: Beyond Planet Earth As a class or in small groups, have student teams share what they’ve learned about traveling in space and living beyond Earth. Have them chart their findings for each team on chart paper, and review as a class.

These small rocky and metallic bodies provide important information about our solar system. PS 1.1c: The Sun and the planets that revolve around it are the major bodies in the solar system. Other members include comets, moons, and asteroids. background for educator When our solar system began to take shape some 4.6 billion years ago, the Sun and planets as we know them today did not exist. Instead, a large disk of gas and dust known as the solar nebula swirled around a developing Sun. Within this disk, countless small objects collided and stuck together, gradually building larger and larger bodies — including the planets in our solar system and other objects in the sky, such as moons, comets, and asteroids. Asteroids are small rocky bodies that orbit the Sun. Most do so in the asteroid belt way out between Mars and Jupiter, but near-Earth asteroids (NEAs) have orbits that come much closer to our planet. Scientists study the minerals found in asteroids for important clues to the formation of our solar system. before your visit Activity: Planetary Mysteries amnh.org/ology/planetology Have students take a virtual tour of our solar system to explore its many mysteries. Then ask them to put their new-found knowledge to the test by taking the quiz. Activity: Cosmic Comic Strips Spark your students’ curiosity about the formation of our solar system and asteroids by having them read these comic strips: Plan how your students will explore Beyond Planet Earth using the Student Worksheets. Plan to have students work in small teams of three or four. Distribute copies of the worksheets to students before coming to the Museum. You may want to review the worksheets with them to make sure they understand what they are to do. • The Formation of the Solar System amnh.org/resources/rfl/pdf/solarsystem.pdf About 4.6 billion years ago, our solar system came into being. This comic strip explains the processes that led to the creation of the planets and the asteroid belt. • Impacts amnh.org/resources/rfl/pdf/impacts.pdf This comic strip shows what can happen — and does happen — when asteroids head for Earth. Activity: Crash Course: Scientists Wonder if a Space Rock Could Destroy Life on Earth teacher.scholastic.com/activities/explorations/space/pdf/scienceworld.pdf Could a space rock destroy life on Earth? Have students read this article to learn more about asteroids, comets, and other space objects and what happens when they collide — with each other and with our planet. during your visit Beyond Planet Earth: The Future of Space Exploration 3rd floor (45 minutes) Begin your class exploration by reviewing the planets using the Solar System Map (located across from the Introduction Theater). Then have students watch the short film to help them prepare for their exploration of the asteroid section of the exhibition.

All rights reserved. amnh.org/beyond BEYOND PLANET EARTH the future of space exploration Activities for Grades 9–12 Designing the Next Mission overview Student groups will propose a mission to space. Each will investigate the essential question: Why and how do we explore space? Groups will research and describe one of two possible destinations: (1) Mars, to search for water as a possible sign of life; or (2) a near-Earth asteroid, to mine for materials. After analyzing evidence collected during their visit to Beyond Planet Earth, each group will present its proposal to the class and make the case that its mission is the more feasible and worthy of funding. background for educator The goal is for students to research a scientific topic — the viability and value of a future space mission — by collecting evidence, making inferences, and synthesizing their findings in writing. Students will supplement what they learn at the Museum exhibition Beyond Planet Earth with Regents Earth Science content and the Physical Setting/Earth Science Reference Tables. Student groups will investigate either a mission to Mars or to a near-Earth asteroid, and ultimately the class will compare their relative feasibility and scientific payoff . NYS Earth Science Core Curriculum 1.2d: Asteroids, comets, and meteors are components of our solar system. 1.2e: Earth’s early atmosphere formed as a result of the outgassing of water vapor, carbon dioxide, nitrogen, and lesser amounts of other gases from its interior. 3.1c: Rocks are usually composed of one or more minerals For instance, at the exhibition students investigating the mission to Mars will use the Mars Explorer interactive to travel virtually to Gale Crater. They will learn that past missions discovered evidence of water along with layers of sedimentary rock deposit. Using their Physical Setting/Earth Science Reference Tables, students will need to infer how sedimentary rock deposits suggest the presence of water, noting that the organization of the sediments can be evidence of water. For example, as a river enters a lake, it slows down and deposits larger sediments first (pebbles, then sand, then silt, etc.). Therefore, if a cross section of soil were found, with smaller sediments on top and larger on the bottom (top to bottom: clay, silt, sand, pebbles), this would suggest the sediments had been suspended in water and then settled, with heavier sediments settling first followed by the lighter sediments. Students investigating the mission to a near-Earth asteroid will visit the Asteroid section of the exhibition to learn about minerals discovered in past missions. Using their Physical Setting/Earth Science Reference Tables, they will need to infer how to identify those minerals on an asteroid, and how the minerals might be useful back on Earth. Both groups will need to base their proposals on the accompanying Proposal Outline, list the pros and cons of their missions, and make the case that their mission is the more feasible and worthwhile. They should take into account distance to travel, potential risks, importance of scientific discoveries, value to humanity, and any other factors that would affect this decision. before your visit Activity: Preparing to Write a Proposal for Space Exploration Divide the class into two groups.
