I thought this article could be helpful to anyone who is trying to plan an astronomy lesson. On the website, there are multiple activities listed and fully described for many different grades. I noticed they had activities available from grades K-12. One activity that I thought could be used as a good introduction to astronomy for a third grade classroom is “Shadow Play.” During this activity, students will learn the daily motion of the Earth. The students will be in a circle around the classroom, with a lamp in the center of the circle that represents the sun. Students will then move around the circle as they also rotate their bodies, like the sun does. When students are facing the lamp, it represents day time and when they are facing away from the lamp, it represents night time. This is a simple activity to get kids moving and thinking before beginning a whole lesson on astronomy.
