This unit was based on the Hop to It: Safe Removal of Invasive Species EiE Lesson. Invasive cane toads have caused many problems for the animals and people of Australia. Using the Engineering Design Process, students went through a series of steps to imagine, plan, and create a cane toad trap. Further, students collaborated using the Engineering Design Process to modify and rebuild their trap design. Students used iPads to document their progress through videos and photos, and also developed a Public Safety Announcment (PSA) to showcase their final design.
