This is a mess free way to help students understand the concept of density in liquids.
Use 7 different test tubes that you can seal and create 2 liquid density columns. Students will color the different mini columns on their lab sheet. They are then asked to analyze their data and color what they think would happen if all 7 liquids were combined.
Also includes short density review, 4 review questions. Teacher lab instructions and an answer key.
Supplies needed are sealable test tubes and basic kitchen liquids.
