2. Bell Work 10-7-15 With what you know about Sidereal and Solar days. Postulate what would result if we used Sidereal days to keep track of time instead of Solar days.

3. Scale Scale Description 4 Through independent work beyond what was taught in class, students could (examples include, but are not limited to): research current and past earth and sun conditions. investigate causes and possible solutions for global climate change. compare and contrast the patterns in the organization and distribution of matter in the sun, earth, moon system. compare and contrast different solar events and their impact on earth. 3 understand how the motions of the sun, stars and planets as observed from Earth relate to the motions of the Earth and other planets in space. understand how the movement and position of Earth influences life on Earth. be able to differentiate between astronomy and astrology. 2 determine the meaning of symbols, key terms, and other astronomy specific words and phrases relating to the Earth, Sun and Moon illustrate the patterns of distribution of matter in the sun, earth, moon system. list the physical properties of the Earth, Sun and Moon. describe the key parts of the Earth, Sun and Moon System 1 show the patterns of distribution of matter in the sun, earth, moon system. select from a list the physical properties of the sun, earth and moon. list the key parts of the structure of earth, sun and moon.

4. Right Now! On the right side of your journal Turn to page 12 in your booky book Sidereal Day. What is it? Draw a sketch Solar Day. What is it? Draw a sketch

5. Work as a group! I want you to work together to figure this out without getting answers from me.

6. Compare and Contrast on the left side….. Sidereal Day 1. 2. 3. Solar Day 1. 2. 3.

7. Summarize your notes by answering the questions from the beginning of the day! What is a leap year? Why do we have a leap year?

8. The Sun, Earth and the moon – to scale

9. This is better…(though not to scale)

10. Learning Goals – In this unit, you will: Learn how important characteristics of the Earth, Moon and Sun compare to each other. Examine evidence that shows the sun is rotating and that the moon is rotating and revolving Explain why the appearance of the moon changes during its orbit around Earth. Examine how the moon influences the earth Explain the conditions and causes of solar and lunar eclipses

11. Right now…15 minutes Left hand side. create profiles for sun, earth and moon. Split your page into thirds…. Picture/name Size (radius in km and mi) Mass (in kg) Density (in g/cm 3 ) Composition Temperature range 2 other facts
