As we approach valentines day this weekend, the first thing that comes to mind is the heart. We can easily relate the heart to science! Lets learn how the heart works! The heart is a simple pump through your entire body. It is a similar concept to when you are squeezing an open water bottle and the water is forced upward out of the bottle due to pressure.
So here is what you will need for today’s experiment:
- Glass Jar
- 2 Plastic Straws
- Balloon
- Rubber Band
- Scissors
- Food Coloring
- Large Pan
Procedure:
- Fill your jar half way with water
- Cut the bottom of the balloon (neck)
- Stretch the top of the balloon and fit it onto the top of the jar. the tighter the stretch, the higher the pressure. This will lead to a more successful experiment.
- Poke two very small holes on the left and the right side of the balloon.
- Place two straws into the balloon one one each side (left and right)
- Make sure there is NO air escaping from the air, the pump will be less effective.
- Slide the other piece of the cut balloon on the left straw and tape to the end
- Apply pressure on the middle of the balloon, watch the liquid move up the straws.
- Place the jar in a pan to catch the water leaving the jar.
If your kiddos try this experiment, send us photos of you and your experiment and you might get to see it during weather on The Four on Tuesdays!
