This is the third in a series of three professional development videos that correspond to lessons taught by Andrew Cloud, an Earth and Planetary Sciences teacher. Andrew’s class, a mixture of 9th and 10th graders, is an inclusion classroom he co-teaches with Barbara Brochstein.

In this lesson, Andrew introduces the concept of eclipses. He asks for student volunteers to represent the Sun (holding a flashlight), the Earth, and the Moon. He then asks the class to think about the order in which the volunteers should be assembled to create the conditions for a lunar eclipse to occur. The demonstration was reinforced by the use of the “Lunar Eclipse Essentials” video. In a final activity, students drew diagrams to illustrate a Lunar Eclipse and a Solar Eclipse.
