Notebook Check 1 Start of school year to Friday 9-16-16 LT: use a model to demonstrate and describe how the rotation of the earth causes night and day. Do Now: 9-15-16 Six friends were wondering why the sky is dark at night. This is what they said: • Alan: “The clouds come in at night and cover the sun.” • Barbara: “The Earth spins completely around once a day.” • Catherine: “The Sun moves around the Earth once a day.” • Devin: “The Earth moves around the Sun once a day.” • Ethan: The Sun moves underneath the Earth at night.” • Felicia: “The Sun stops shining.” Which friend do you think has the best reason for why the sky is dark at night? Describe your ideas about why the Earth is dark at night and light during the day. Agenda: day and night • Discuss do now. • Sun Earth model demonstration • Define: rotation, axis, revolution • Diagram of earth sun relationship • What represents the following in the Earth/Sun model… • The Sun? • The Earth? • An observer from Earth? • Reflection: use the RERUN acronym • Demonstrate the following: to reflect on what you learned • Day to night today’s learning target. • noon • Reminder: notebook quiz and • midnight stamp count tomorrow. • sunrise • Sunset • Define and put in glossary: rotation, axis, revolution. • Draw a labeled diagram with sun and earth to demonstrate your understanding of the cause of day and night. • Label the following: sun, earth, axis, rotation, revolution, day, night, sunrise, sunset LT: Generate evidence that the earth is a sphere. Do Now: 9-14-16 Agenda: A Round, Spinning Earth 1. How do we know the earth is round? What evidence do you have? • 4 Aristotle proofs of round earth https://www.youtube.com/watc h?v=vzImgJCgUkg • Longitude vs latitude vs altitude • Sailing ship model construction • How do observations of ships at sea provide evidence of Earth’s shape? • Round earth/flat earth simulation • What is horizon? • Columbus first voyage reading • Define altitude, latitude, longitude on right side • Multimedia guide longitude/latitude • Find 0, 0 on the globe and map. • Find the coordinates of Tacoma, WA. • How do observations of ships at sea provide evidence of Earth’s shape? • Make sailing ship • Demo on map and globe and multimedia • A horizon is the imaginary line between where the sky meets the earth or ocean. How is the horizon different for the flat Earth and the round Earth? • Read pg 3-6. What was learned about the world from Columbus’ first voyage? Who do you think deserves credit for discovering the Americas? LT: Generate evidence that the earth is a sphere. • For your reflection, write a claim, evidence, reasoning about how you know the earth is round. LT: be able to describe how moving the point of view away from the Earth changes the observations you can make about the Earth's surface. Do Now: 9-13-16 Agenda: School to Space • What is your cosmic address? Describe you location in the universe as accurately as possible, right down to this classroom. • Planetary science brainstorm • Bird’s eye view through google earth • Textbook. • pg 79-84. How did they take each photo? • Reflection Planetary science brainstorm 1. What is the closest star to Earth? 2. How many other planets are in our solar system? 3. What other objects are found in the solar system? 4. How big is the Earth compared to other objects in the solar system? 1. Google maps. Search Stewart middle school. Switch to Earth. 2. Click ft to switch into meters/km. 3. Make observations at each altitude on “bird’s eye view” handout. 4. When finished, turn in your computer and get a textbook. Look at pg 79-84 and write a prediction about how each photo was taken. LT: be able to describe how moving the point of view away from the Earth changes the observations you can make about the Earth's surface. Reflection • Reflection: use the RERUN acronym to reflect on what you learned today’s learning target. LT: assess my readiness for 8th grade science. Do Now: 9-12-16 1. What is the message behind the two cartoons? 2. How does the message relate to school? Agenda: 8th grade science pretest • Discuss meaning of cartoons • Scenario discussion • Pretest on variables and space science Group project Scenarios: 1. think to yourself and write a response on right side. 2. share with your table (whip around) 3. Share out with class. 1. One person from your lab group is hogging the supplies. 2. A person at your table hasn’t written anything on your groups’ poster. 3. Your group’s experiment results are different from the group next to you. 4. A person from your table leaves to socialize with another table. • Reflection: What do you remember about Planetary Science from 6th grade? What topics do you need to review/relearn?
