Can you build something that keeps a cracker from breaking? In this real-world engineering challenge, students design protective packaging to keep a fragile object (like a cracker, chip, or cookie) safe when a book is dropped on it. Children learn that engineers design packaging and protective gear to keep things safe, and they iterate on their designs through testing. Includes an introductory page connecting to real-world packaging engineering, step-by-step design and testing instructions, a st
