Here's a tip on how to look like Mrs. Frizzle of the Magic School Bus without having to spend a lot of money on your wardrobe. Cut out designs in felt (like trees showing the four seasons, the water cycle, life cycle of a frog, etc.) and spray bonding glue on the backs. Let the glue set up for at least five minutes. Apply the designs to an old apron and voila, you're Mrs. Frizzle! The designs can be removed and stored on waxed paper so one apron is sufficient for all your science units. The children will love it and will be able to guess what you'll be teaching next.
