After they completed their bridge tests, second graders will be completing their culminating project in their civil engineering unit--designing and testing their own bridges! Because engineers spend time brainstorming and planning out their designs, second graders will be doing just that! Here are the details regarding their bridges!
Criteria--The Bridge MUST...
1. Be at least 15 inches wide!
2. Hold as many weights as possible.
3. Allow a toy barge to sail under it.
4. Allow toy cars to travel on top of it.
Constraints--What are you limited to?
1. Materials!!!
