DensiTEACH Density Challenge Set
Learn how density fluctuates among 6 balls that may look the same, but are made of different materials with different masses. Each density experiment lets students see how vinyl, steel, wood, foam, resin, and polyurethane react during weight and water tests. Students discuss how mass impacts density when all samples have the same shape and size. They also discover the connection between mass and objects with a high or low density. Set of 6 includes 1 of each ball (2" dia). Class Set of 24 features 4 of each ball and lesson direction that is adaptable for grades K-4 and 5-8. Recommended for Elementary and up.
