Observe and explain the Sun’s position at different times during a twenty-four-hour period and changes in the apparent shape of the Moon from one night to another.
In this unit, students explore science phenomena related to patterns that result from Earth’s rotation and the moon’s orbit around the sun. This page provides a brief overview of lesson two of this unit, in which students conduct two investigations and use the patterns they discover to make predictions about the future positions of the sun, moon, and stars in the sky. In the first investigation, students observe the sun’s position in the sky at different times of day, drawing a diagram (model) of the sun’s position above the horizon. In the second investigation, students use a sundial model to explore the relationship between the sun’s position and the length of shadows.
