Do you like using your imagination to build things that solve problems? If you do, you’re thinking like an engineer! 3A identified and solved the problem of how to scratch an itchy back by designing and creating our very own back scratchers. First, we started by gathering some materials. We decided that we would use cardboard tubes, rulers, pencils, plastic forks, tape, and modeling clay. Then we drew models of what we were imagining. Next, came the fun part. We built and tried out our prototypes. Take a look at our amazing creations.
