Go out next to the stairs and look for the Moon exhibit. Faces of the Moon: Try this: Rotate the moon around the Earth making sure the arrow is pointed at the Earth. Now rotate the moon around the Earth with the arrow always pointing to the ground. In the first activity (where you pointed the arrow at the Earth while orbiting the Earth), what would inhabitants on Earth see of the moon? Would people see the same or different sides? Weighing the Difference Try this: Lift the 35lb exercise weight on the Earth (on the left). Now lift the exercise weight on the moon (on the right). Discuss with your partner your observations. Did they feel like they had the same weight? (Keep in mind both exercise weights in this exhibit are representing two weights with the same mass) How do you think mass & weight are connected? (Look at the board) ___Mass & Weight are the same ___Weight is an objects mass times the acceleration of gravity on whatever planet or moon the object happens to be. ___They are related but I don’t know how. How much do you weigh on Earth? How much would you weigh on the Moon? (Take your weight on Earth and divid by 6.) ______ ÷ 6 = _________ In the second activity (where the arrow always pointed to the ground), would the inhabitants on Earth see different sides of the moon? How does the Moon actually orbit the Earth? ___ Like the first activity where one side of the moon is always pointing at Earth ___Like the second activity where different sides of the moon are seen by Earth How much of the moon do we see when we look at it from Earth? Phases of the Moon The sun always shines on half of the Moon’s surface, but we can’t always see that half from Earth. What object in the solar system did the light from the side of the exhibit represent? ___The Earth ___The Sun ___Light reflected from other planets in the solar system Why do we see different shaped moons when we look in the sky at different times of the month? Draw four of the different shapes we see of the moon.
