9. Imagining Bridge Designs!

Civil Engineering

Civil engineers play an important role in all our lives. They are the ones who design and construct structures that all people use, like bridges, dams and public buildings. They have to consider the materials for their structures, where they are located (with the help of geotechnical engineers, of course!) and how various forces will interact with their structures (like cars crossing it, possible earthquakes, or the overall load on top of it!

9. Imagining Bridge Designs!

A second grader's "Imagine." Notice the difference between the two designs. Will one work better than the other?

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!!!
