In this activity, students predict then examine the density of common household liquids.
Dense liquids will sink to the bottom, while less-dense liquids move above them.
In this activity, students predict then examine the density of common household liquids.
Dense liquids will sink to the bottom, while less-dense liquids move above them.
Predict, test and explain the relative densities of common liquids.
Per Demo:
1 tall, clear cup
3 liquids of different densities (choose from): honey, corn syrup, dish soap, water with a drop of food colouring, vegetable oil, food colouring
Teacher Tips
Pour each layer slowly, because mixing can make it more difficult to see the intended result. Start with the densest liquid, then add liquids with lower densities. Tilt the cup and pour onto the side of the cup to cause the least disturbance to the liquids.
