For this lesson, students will work together to make a large scale pendulum to create works of art as a group. This project is done on a large scale and so it is best to do it outside or in a gymnasium. Students will build the pendulum, using the traffic cones to hold the long board. Students then will attach the string to the center of the board and attach the condiment bottle to the string with the paper clip. The nut or washer will be attached to the string to add weight. (Pieces are large 7-8 feet tall, each class will make 6-7 pieces of art.)
