Here is the task:
Create a catapult which will launch a pom-pom as far as possible. The image below is how you might like to start.
- popsicle sticks
- rubber bands
- pom pom
- bottle cap or spoon
Once you have made a basic catapult, test it out. Launch your pom-pom 10 times and record the distances on a Google sheet. Create an insert a graph to show the data.
Then the challenge is to make improvements (iterate) and see if you can shoot your pom-pom even further. Once you have created a more effective catapult, test it 10 times, record the distances and add to your Google sheet.
