1. The lesson plan is for a 2nd grade science class on the topic of day and night. It involves interactive activities using models and demonstrations to teach students that the Earth's rotation on its axis causes day and night.
2. Students will use balls, string, and flashlights to model the Earth's rotation and how it leads to different times of day in different locations. They will also observe images from webcams in different parts of the world showing day and night at the same time.
3. Assessment includes fill-in-the-blank questions to test students' understanding of what causes day and night and using worksheets to record their observations.
