Why does the bathtub water rise when a child gets into the bathtub? The concept of fluid displacement needs to be taught with many different examples. This Kidspiration template allows 3-5 students to predict whether 10 items will float or sink in water and then asks them to measure the amount of fluid displacement that takes place when an item sinks. This template could prepare students for a more in-depth discussion of fluid displacement and the many concepts related to fluid displacement.
