In this activity, students investigate how craters are formed on the moon and why they remain on the surface over time (compared to Earth). This resource provides some background information with explanations and includes a link to a DragonflyTV video (the clip is from 2007, so parents/guardians may want to choose a more contemporary video instead). Given the simplicity of the activity (both supplies and procedure), this resource is a fit for younger students, however, it would be best to complete outside given the potential mess and spills that may happen.
