5-layer suspension- Worked beautifully!! (Especially with blue food coloring.)
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.
Use this recording sheet as a fun way to introduce your students to the scientific method. Students will love making their predictions and then preforming an experiment to test their hypothesis. Great for a whole group lesson or small group center!
