Teach your students about what it takes to build a boat that will float using this Teacher Guide from The Cat in the Hat Knows a Lot About That! 

What makes a boat float on water? Do certain shapes float better than others? With a little help from the Cat in the Hat, your students will use the Engineering Design Process and discover that both the type of material and the shape determine whether a boat can float. The class will then work with aluminum foil to create their own boats that they will test in class. In this guide, videos from The Cat in the Hat Knows a Lot About That! are used to demonstrate these concepts, and make your students' engineering adventure an exciting one!
