What is water displacement?

Water displacement is a way to measure the volume of an object with no straight sides. Students read the water level, lower the sample in, read it again and subtract.

Why does one drink can sink while another floats?

An object sinks if its overall density is greater than the water around it. The sheet has students calculate the density of a sugar can and a zero-sugar can to see why.

Written by Adi Ackerman, Head Teacher

These 7th grade density worksheets put density to work with data. One sheet graphs density against sugar percent and compares a sugar can with a zero-sugar can to explain sinking and floating. The other measures volume by water displacement and calculates density to name unknown metals. Both sheets have answer keys.

Frequently Asked Questions

Density is mass divided by volume. Students find volume from the rise in water level, then divide mass by that volume.
