Description:

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water? Included in the lesson plan are several investigations, throughout each of which learners are encouraged to try changing variables in their experiments such as different liquids, different types or amounts of soap, or different temperatures and salinity of water. This activity can be used in conjunction with the "Breaking the Surface" activity found in the same educational resource.
