Today's activity we have a fun, found object activity for you to take for a spin. Just download the activity work sheets and begin collecting the materials for this activity. If you don't have any of the specific materials listed we challenge you to use you ingenuity to find replacements. No old CDRs? Cut a disc out of cardboard. Don't have a marble? Try to find something else small and round (that you can glue) or maybe even a small round ball of clay. Just click on the image above and give it a try!
