Science project
Dishing Out the Colors
Grade Level: Preschool-1st Grade Type: Chemistry
Objective
In this experiment, we will find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.
Research Questions
What properties does surface tension itself affect?
Surface Tension allows liquids to resist an external force. It acts as a sort of “barrier.” Because of this property, some objects that are denser than water can actually float and insects can walk on the surface of water.
Materials
- Food coloring in colors of your choice
- Milk
- Dishwashing liquid
- A large dish with raised sides
Experimental Procedure
- In a pretty deep dish, add about ½- 1 inch of milk.
- Put a few drops of food coloring on the surface of the milk. The colors, amount, and arrangement can be however you like.
- Put 2 drops of dishwashing liquid inside. Something really cool should happen. What happens?
Terms/Concepts: Surface tension; cohesion; Properties of Liquids; Floatation
