Explore Alliance Presents: How Do You KNOW? – Episode #9: 'Impactors and Craters'
This activity is larger, messier, and a lot more fun that the clay model we made in Episode #4. In the last activity, we pressed various size balls into a clay surface to make ‘craters’, depressions that were smooth and round, but not very exciting or dynamic. We’re going to take this up a notch and let kids see the crater making process as it happens! By dropping weights into pans of flour to look at the resulting craters, plus the ejecta – material which is blasted out of the crater on impact.
Dr. Barth's high impact presentation gives students perhaps the best understanding of how craters if formed by impactors on this episode of 'How Do You KNOW?'
