9. Hands-On Exploration Use toothpicks to experiment with possible designs. Use the Play-Doh to hold the toothpicks in place.

10. Blueprints Create 4 blueprints for different bridge designs For each blueprint 1.Why did you choose this design? You must include reasoning based on Internet research and hands-on exploration. 2.Label the parts of your design using the vocabulary from today.
