Next, we made bubble art by adding tempera paint to a mixture of water and Dawn soap...then we used "found items" (lids and sponges) to make a book on bubbles...(the last picture shows the pages in his book. )

Bubbles!
Bubbles are one of Brett's favorite things, so we decided to do a little investigating :) We learned that bubbles are pockets of air trapped inside a liquid and also that the surface tension in water causes its molecules to cling together so that on it's own, water doesn't produce many of these air pockets. It needs to have more space in between the molecules. So, when you add soap, it breaks the surface tension allowing the pockets to form-resulting in bubbles!
