Accent: What Is Density? Kit

Model solids, liquids, gases and watch how they behave. Density - a term often misused and misunderstood - describes how closely packed the particles of a substance are and is usually expressed in terms of comparison. In this kit, comparisons are made to water, because the results are obvious: the less dense substance will rise to the top or float. By modeling gases, liquids, and solids (dough figures progressively more compact) and floating them in water, your class will see that it is volume, not weight, that determines the behavior of a substance. Includes - Cans of Magic Dough in four colors, 611-2000 Density ID Set (12 unique specimens), 12 plastic containers, 250 toothpicks, 300 blue foam squares, instructions with Student Journal Pages, and Teacher Pages and challenge questions.
