=Measuring Density! =
 * ** Objective of your share: ** The learner will demonstrate the ability to understand density by observing how well various objects float in water.
 * ** Materials needed: **
 * container filled with water
 * various items that can be dropped in water (i.e. dice, beads, sponge, wood block, toy car, ping pong ball, bouncy ball)

 * ** Summary: Students are divided up in to groups of four. Each group is given a plastic container filled with water. Next, students are to "test" the density of various objects. This can be done by observing how well various objects float in water. Students take turns placing different objects in the water. Students will discuss, reflect, and record their results on their chart. Did the object float? What does that tell us? **
