Simple Experiments with Water
The Splash exhibit is all about moving water in different ways, using water pressure, creating water currents, and using directional flow. These simple experiments will provide opportunities to move water in different ways.
What You’ll Need:
- 2 soda pop bottles
- Food coloring
Collect supplies and clear a workspace.
What to Do:
- In a sink or outdoors, add food coloring to a bottle filled with very warm water. Shake.
- Hold a paper square over the mouth of a bottle filled with cold water. Turn the bottle upside down.
- Carefully rest the bottle’s neck on the neck of the warm bottle. Holding the necks tightly, pull the paper away.
- Result The colored warm water rises into the cold water when the two meet. Molecules pull away from each other in warm water, making it lighter than cold water.
Length of Activity:
Set Up – 5 minutes if supplies are readily available
Executing the Experiment- 15 to 20 minutes
