Unit Map

Kids engineer a tower and are introduced to the Engineering Design Process as a problem-solving tool.
Kids explore the idea that they, as engineers, can design and improve technology.
Kids are introduced to the problem: engineering a trap to catch invasive cane toads. They will also build some traps that need improvement in order to be successful.
Using their knowledge of the cane toad problem, kids will use the steps of the Engineering Design Process to engineer their own cane toad traps.
Kids continue using the steps of the Engineering Design Process as they create their cane toad traps, test them, and improve their designs.
Kids present their cane toad traps and knowledge of the Engineering Design Process by creating Public Service Announcements that tell others about the dangers of cane toads.
