Now that you have collected and thought about your data, discuss again what properties of an object you think determine whether it will sink or float.
For example, if a rock has a mass of M = 65 g and a volume of V = 23 cc, its density is
Sinking and floating have something to do with density. We will explore this more by finding the density of some objects and looking for patterns in the data.
- Complete data tables like the ones below on the Sink and Float Data Tables page in the Student Activity Book. Write the density of each object as a ratio of its mass to volume.
