Pendulum painting. Very cool for STEM learning. I did this once at the Science Museum of Virginia years ago as a student on a field trip. Would love to recreate it as a classroom learning experience. Via The Children's Art Group: Meetup 22: Pendulum Painting.
This product gives step by step directions for building a pendulum from plastic pipe. The pendulum is used for creating fantastic works of art while integrating science and math (STEAM). Following these directions must be done by someone who has the tools and expertise to safely cut, drill, and glue plastic PVC pipe.
Pendulum Painting. This would be a great science based lesson for EOY. This was always one of my favorite projects in middle school and I still have all my "drawings" now. Great way to tie a lesson in with this and very inexpensive. - Heart-2-Home
