Assessment Review Guide
Assessment Dates: May 30 for B Day, June 3rd for A Day
Part 1 will be a short 20-question survey of general knowledge questions in a multiple choice or fill in the
blank format. Part II is an “illustrate and describe” questions on very large paper. (larger than A3)
What you should know…
Comets
What is a comet? What two locations do they come from? What are they made of? How old are they? How might they
relate to life on Earth? Why do they have tails? What are proteins made of?
Earth
How long does it take Earth to make one complete orbit around the sun? What causes the seasons? Can you illustrate the
spring equinox, summer solstice, autumnal equinox and winter solstice in relationship to each other and the sun? (Northern
Hemisphere)
What is Aurora Borealis and how does it relate to Earth’s magnetosphere and the sun?
What happened in Air Force One with President Regan and how does it relate to the sun?
Why doesn’t all of sun’s electromagnetic energy hit the surface of the Earth? What stops harmful UV rays? Why?
The Sun and Stars
What is the solar cycle? What’s the pattern? What effect does solar wind have on Earth?
Why does the sun shine? What is stellar fusion? What isotopes of hydrogen are involved in this process?
Why do stars come in different colors? What is the brightest star (apparent) in the night sky as seen from Earth?
What is the difference between apparent magnitude and absolute magnitude?
What are 5 ways mass influences a star?
About how far away is the sun?
What is the chorus to the sun song? “The sun is a mass…”
Why do Hubble images of stars have 4 points?
Describe a super high mass stars life cycle? Describe a high mass stars life cycle? Describe an average mass stars life cycle?
What is a black hole? How are they formed? Where can we find them? Why do stars not make elements higher than Fe or
iron? Why is a neutron star called a neutron star?
Chemistry
What is an ion? Where might we find ions? What is an isotope?
What is hydrogen made of? What is a proton made of? What are the charges for the following particles: proton, neutron,
electron? What do all the elements have in common?
Why is the periodic table called the periodic table? Why does it “look” the ways it looks? What determines that? What
information does it reveal about each element?
What is a spectroscope? What is it used for? How can we tell what stars are made of? How can we tell what dust in nebulas
is made of?
Forces and Energy
What does the formula E=MC2 tell us?
What are the 4 main forces from strongest to weakest? What force has organized the universe into galaxies?
What is the electromagnetic spectrum? Know the order from longest to shortest wavelength. What is wavelength &
frequency? What electromagnetic energy is ionizing? What does ionizing energy do?
What is the difference between incandescent & a fluorescent light?
What does a prism do to white light? Why?
Part II: You will be asked to illustrate and describe what the universe is made of and how do we know. You will have a class
period and hw time to plan your work. Your final work will be done in class without any support material and is limited to
approximately 1 hour. Start planning!
