Making An Impact!

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape. Then, learners illuminate the moonscape with a flashlight to investigate why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon. This activity will help learners understand why the Lunar Crater Observation and Sensing Satellite (LCROSS) Mission launched in 2009 is targeting craters at the Moon's north/south pole to search for signs of water ice. This activity should be conducted outdoors at night or indoors in a darkened room. A version involving Play Doh (or clay from provided recipe) is included in the guide. The PDF contains step-by-step instructions, photos and presentation tips. [Activity is publicly available through a web crawler capture on Archive.org.]
