Give each student one drop of soapy water. Repeat the steps above for small groups, as necessary. Place objects in a tub of water of varying depths. Look through the water at the objects. Add soap to the water.
Water has cohesion - the molecules hold together.
We can break a water bubble apart and put it back together. The bubble stays together as we move it. Water magnifies objects. Soap causes the water bubble to fall apart and spread out, also soaking through the wax paper. Look at the water bubbles through hand lens.
