This is a cute idea to adapt for an art project with an Earth Day theme. Give each student a square with a quarter circle on it for them to do their drawings. Glue your students' drawings together to form "Earth Circles" and create a colorful Earth Day bulletin board display.
Earth Day is a great time to read your students "The Lorax" by Dr. Seuss. This teacher chose "I Can Help Save the Earth By ..." as the title of her Earth Day bulletin board display. She had students write their answers inside cute Lorax templates.
