Another one of their final projects was a collaborative effort (which can be found all over Pinterest but I think originated with this teacher!). First, they watched this video of bubbles in slow motion. Then, each student had a piece of 12" x 18" black paper. They used lids to trace their circles and oil pastels to add the colorful translucent shine and reflections. The most fun part was spreading out on the floor and planning the placement of the bubbles (which were to float from one student's drawing to their neighbor's. These are currently hanging as a large mural outside the P.E. doors.
