Design a device that measures the varying patterns of daylight. Define the problem by asking questions and gathering information, convey designs through sketches, drawings, or physical models, and compare and test designs.
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.
