### Transcript

• 1. Relationship between Earth, Sun and Moon
• 2. As The Earth Turns &#x2022; The rotation of the earth causes a predictable change &#x2026; &#x2022; What is the result? &#x2022; Hint? &#x2022; The side of earth facing the sun experiences day and the side not facing the sun experiences night. &#x2022; This cycle occurs every 24 hours.
• 3. As the Earth Travels &#x2022; The revolution of the earth causes a predictable change &#x2026; &#x2022; What is the result? &#x2022; Hint? &#x2022; This cycle takes 365 days &#x2022; What causes the earth to experience seasons? &#x2022; Let&#x2019;s find out by conducting a lab investigation! Reasons for the Seasons In this lab, you will use an Earth-sun model to make observations about factors that contribute to the seasons. Problem: What effect does the tilt of Earth&#x2019;s axis have on the heat and light received by Earth as it revolves around the sun?
• 4. As the Sun and Moon Pull rotation and revolution the moon around the earth and the earth around the sun causes a predictable change&#x2026;.. &#x2022;What is the result? &#x2022;Hint? &#x2022;Tides are caused by the gravitational pull of both the sun and the moon.
• 5. As Gravity Pulls &#x2022; What causes the tides to be high and low? &#x2022; Let&#x2019;s look at the animation again. &#x2022; Keep these questions in mind: &#x2022; What do you notice about the positions of the sun and moon during the high and low tides? &#x2022; Which seems to have more of an effect, the sun or the moon? &#x2022; Don&#x2019;t forget to look at the key/legend at the bottom.
• 6. As Water Moves &#x2022; Let&#x2019;s Find Out why there are bulges of water.
• 7. As the Bulge Goes &#x2022; Let&#x2019;s Find Out! why the water bulges on both sides of the earth. &#x2022; Centripetal force and rotational inertia &#x2022; Now THOSE are science terms! You don&#x2019;t have to remember those terms, but they are cool science words! &#x2022; Let&#x2019;s do a demonstration that will show you what happens to the water &#x2013; watch what happens to the ribbon!
• 8. Round and Round They Go &#x2022; Are there other predictable changes from the motions of the sun, earth and moon? &#x2022; Hint? &#x2022; Eclipses! &#x2022; Another hint? &#x2022; Phases of the moon!
• 9. So What Do We Need To Know? &#x2022; The rotation of the earth causes &#x2026;.. &#x2022; The revolution of the earth causes &#x2026;. &#x2022; The tilt of the earth&#x2019;s axis causes uneven heating of the earth, which causes &#x2026;. &#x2022; The gravitational pull of the sun and moon cause &#x2026;. &#x2022; The moon blocking the sun or the earth blocking the moon causes &#x2026;. &#x2022; The relative position of the earth, sun and moon result in &#x2026;.
