Project ·
Engineers try ideas, observe what happens and change one thing at a time. Build a small paper goal and test it with a rolled paper ball. Ask a grown-up for help with cutting.
Gather your materials
Scrap paper; tape; ruler; a paper ball; child-safe scissors with grown-up help.
Give it a try
- Fold two paper strips into upright posts and tape them to a folded base.
- Connect the posts with a third strip for the crossbar.
- Roll a paper ball gently toward the goal.
- Widen the base or add folded braces. Try again and compare what changes.
