Bridge Research



Today you will do some important research to collect information that you can use to build your bridge later this week. Work with your group to follow the steps below!

1. Go to the site http://www.pbs.org/wgbh/buildingbig/bridge/basics.html
- Read through the "Bridge Basics" as a group
- Make notes on the positives an negatives of the beam, truss, arch, and suspension bridge
- Draw some simple sketches to help you remember each bridge

2. Go to the site: http://www.pbs.org/wgbh/buildingbig/lab/loads.html
- Make detailed notes on how the weight of structure, weight of load and a eathquake can affect a bridge
- Make a few diagrams to help you remember what you learned

3. Go to the site: http://www.pbs.org/wgbh/buildingbig/lab/shapes.html
- Make detailed notes on each of the shapes you can use to crete your bridge
- draw a quick diagram so you can refer to them when you are building your own bridge

4. Google: Cantilever Bridge
- Write five points about the positives of this type of bridge
- draw a quick sketch of what it looks like






Good luck.
