Students learned what surface tension in water was using pennies and water drops. They observed pepper scattering on the surface of water when soap was introduced to break the tension. They tested 6 different liquids other than water using the same method.
Smart idea to only change one thing at a time- that is good science! I love your ideas for further research!
