Standing in the Shadow of Earth

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon. Shadows are not just what we see on the sidewalk, they are 3-dimensional. Learners will compare the shadow that an Earth globe casts with what they observe in the evening sky at sunset. The PDF contains step-by-step instructions, photos, presentation tips, and links to background information. The activity needs to be done on a clear evening with a view of the Eastern horizon.
