This is a great experiment to show different densities of liquids. Have students record their predictions then watch as students create a rainbow in a glass. Liquids with higher densities will sink to the bottom while lighter liquids will go to the top.
5-layer suspension- Worked beautifully!! (Especially with blue food coloring.)
Floating eggs experiment
Rainbow Density Experiment uses only sugar water and food coloring. Includes alignment with Ohio standards.
