Suspension bridge vs. Panel bridge

After reading an article, on "Monkey Crossing" from Scholastic News, students were to test a suspension bridge versus a simple beam bridge. Students investigated the following questions: 

1. Can a suspension bridge carry a greater load than a simple beam bridge? 

2. Which type of bridge would you build for your animal crossing?

Below is a picture of a former student with his suspension bridge and there is also a video of a student performing his experiment.
