Watch the short NASA Brain Bites video "Why Do Astronauts Practice Underwater?" and use the accompanying resource sheet to explain sinking and floating. NASA astronauts simulate floating in space as they train for spacewalks in a huge pool called the Neutral Buoyancy Laboratory. The video shows the NBL, and the resource sheet lists questions, answers and resources to stimulate a discussion on density and Archimedes' Principle. The resource sheet includes links to more buoyancy activities.
