Students are interested in and aware of the sun, moon, planets, stars, and other objects in the sky.
Through demonstrations and models, they distinguish the unique features of the Earth and develop an awareness of how day, night, and the seasons are caused by the Earth's movement around the sun. Activities Students role play the positions of the sun, moon, and Earth. Students use a globe, a flashlight, and a small ball to demonstrate the day and night positions of the Earth, sun, and moon. Using flashlights and graph paper, students compare the amount of light that covers a surface that is flat and a surface that is slanted. They explain how the Earth's seasons are caused by the differences in the angle of the sun's rays striking the Earth.
