In this earthquake exploration worksheet, students complete 2 prior knowledge questions, then use "2D Eclipse Gizmo" to conduct several activities, completing short answer questions when finished.

In this moon worksheet, students fill in the different phases on the moon on a diagram and label each phase. Students compare a solar and lunar eclipse. This worksheet has 2 fill in the blank and 3 short answer questions.

Learners examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.

Students discover how Aristarchus, a Greek astronomer around 230 BC, used a simple observation of the eclipse of the Moon, plus clever reasoning, to deduce the distance of the Moon. They practice the same calculation technique.
