Young scholars make accurate drawings of a classmate's shadow. They note position of the sun in the sky. They identify a connection between the direction of the shadow and the location of the sun. They observe changes in shadows over time.

Students explore the rotation of the earth. In this science lesson, students view photos of various places around the world. Students conduct an experiment in which they can see how the earth's rotation creates shadows on the earth.

First graders study that day and night result from shadows produced by Earth's rotation. Students work to show how shadows are produced, look for and identify shadows and observe shadows produced from different sources.

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...
