Here is another super fun science experiment to do with your kids in your homeschool classroom! This Surface Tension Science Experiment is a great way to use simple household items to teach kids all about surface tension and how it’s created.
I love using simple items from the kitchen to teach the kids about science. It’s so easy to help them understand various concepts with fun, hands- on experiments. Having something like this Surface Tension Science Experiment is the perfect way to keep their interest. Kids get to play while learning, what better way to teach?
Surface Tension Science Experiment for Kids
- 1 small bowl of water
- 1 small bowl of milk
- yellow liquid food coloring
- blue liquid food coloring
- ground pepper
- dishwashing liquid soap
1. Sprinkle pepper on the surface of a bowl of water. Dip a toothpick into the dishwashing liquid soap. Gently touch the surface of the water with the soap end of the toothpick. Watch the pepper move very quickly to the side because the surface tension is disrupted.
2. Add 2 drops of yellow and 3 drops of blue food coloring to the milk. Dip a toothpick in the dishwashing liquid soap. Gently touch the surface of the milk with the soap end of the toothpick.
What happens? The colors quickly move around in the milk.
Try other liquids such as apple juice and coffee. Do they act the same or different?
