![]() Once a group’s Crazy Contraption is functioning, students will then: It should move from step to step smoothly to complete a task. Students will evaluate their crazy contraptions by testing the contraption. The teacher will approve the group design before distributing student materials. Students should document their designs using the Student Guide. Students will collaborate within their group to share their individual design and create a group design that follows the above criteria. Take more than four seconds to transfer energy through its system.īe safe and not damage any other contraptions. It must be free-standing.īe constructed from materials listed on page two of the build guide. Operate completely on its own, once started.įit in the area directly above the 12” x 12” base. Each mechanism will link with the next mechanism to transfer energy from start to finish. Transfer energy through a series of mechanisms. The teacher can scale down the task to move a ping-pong ball through the machine from start to finish. The teacher can specify the task or students can create their own depending on the creativity of the group and time allotted. ![]() ![]() The goal of the contraption is to complete a task (turn off the light, pop a balloon, etc.). ![]() Students will work with their small group to design a Crazy Contraption using the Student Guide. This can be helpful if simple machines have not yet been explored or if students need additional support. If needed, students will explore simple machines by creating small versions of simple machines using the materials provided. The teacher will share some examples of the different simple machines using the Crazy Contraption PowerPoint. Students can self-select their own roles or the teacher can assign roles as needed. Project Manager (create a poster, document steps, and keep the group on track) Each group will collaborate to make their own Crazy Contraption.Įach group will have the following roles:Įngineer (design and calculate using formulas) The teacher will then divide class into groups of 2-3 students each.
