1.1 SWBAT explain how the earth moves around the solar system by writing about precession, nutation,
and barycenter.
1. Draw the shape of Earth’s orbit around the sun.
2. Explain why Earth takes the path you drew in question #1.
3. Think about the shape of the Earth’s orbit around the sun. How does this shape affect the speed at
which the Earth travels, particularly with regard to Kepler’s 2nd law of Planetary Motion?
4. What is the angle of the Earth’s tilt on its axis?
5. Explain what Kepler’s laws tells us. (Include illustrations)
6. Explain why the sun is always in motion. Use both the sun and Earth in your example.
7. What is precession and why does it occur?
8. What is nutation and why does it occur?
9. Write down any factors that may play a role in the barycenter of the sun and the different planets.
10. Why are there 24 hours in each day on Earth?
1.2 SWBAT explain how the Earth’s rotation and revolution about the Sun affects its shape and is related to
seasons and tides
1. What is the main factor that changes daily conditions on earth? (Night and Day)
2. Which two factors are responsible for Earth’s seasons?
3. Why do the northern and southern hemispheres experience opposite seasons at the same time of the
year?
4. What is a tide? Explain how high tide occurs.
5. Diagram the earth and which section is the widest. Explain why this section is the largest. (IncludePoles, Equator)
6. How long does the moon take to orbit around the Earth?
1.3- SWBAT explain how the sun produces energy by analyzing life on earth and being able to describe this
in writing.
1. Explain combustion.
2. What is the difference between nuclear fusion and nuclear fission?
3. Describe an example of nuclear fusion.
4. How is a fusion reaction different from a combustion reaction?
5. Why are nuclear reactions on the sun important for us on Earth?
6. Explain how energy from the sun travels to the Earth.
7. How does Earth’s atmosphere affect the type of solar radiation we receive?
1. 4 - SWBAT Explain how solar energy makes life possible on Earth through the process of photosythesis
and differential heating
1. Does the ocean or land heat up faster? Explain Why.
2. What is heat capacity?
3. How does the earth’s magnetic field protect the planet from the harmful effects of radiation?
4. What is photosynthesis?
5. What goes into plants in order to create energy?
6. What product is created in plants after photosyntesis?
