This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

The main variables in a science experiment are the independent variable, the dependent variable and the control variables. The Independent Variable is what we change or control in the experiment.

This week’s experiment looks into how temperature affects water density. For this experiment, you will need a pan, cold and hot water, food coloring and two glasses. Watch the video in the ...
