Although they may look like glued together piles of junk, rest assured our students were immensely proud of their Push and Pull Machines. In yet another Scrapheap Challenge, this one at the commencement of our science unit on forces, students’ teamwork skills were put to the test to design a device which incorporated both a push and pull force.
My students love to be given creative technology group work challenges, which we call Scrapheap Challenges. We gather up reusable household items such as cereal boxes, cardboard cylinders, bottle tops, etc and once our stockpiles are sufficient its time for another Scrapheap Challenge! Besides setting group work goals, our only two rules are: don’t burn yourselves on the glue gun and the teacher does the tricky cutting. This one was undertaken at Easter time. The brief – design a harmless Easter Bunny trap. The results – adorable.
