This is a simple STEAM building challenge that you can use with book care lessons. During class, go over the basics of book care. Instead of a worksheet, have your students build something that will protect their book from things like animals, baby brothers and sisters, rain, food, or even aliens. I supplied my students with foam boards, aluminum foil, popsicle sticks, cotton, glue and scissors because that's what I had on hand. You can alter that, kids will build with what they have and use their imagination.
