Students observe and investigate why water has a strong surface tension.

Students learn about and experiment with the concept of surface tension. How can a paper clip "float" on top of water? How can a paper boat be powered by soap in water? How do water striders "walk" on top of water? Why do engineers care...

Watch Scientist Joe fashion art out of water, paint, and surface tension. Links to video of the experiment.

Explains the role of surface tension in a liquid and how oil can be used to keep water from boiling over.

Science Bob presents instructions for a science demonstration of how to build a soap-powered model boat using common supplies with information on how it works.

Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it...
