Supplies, instructions, resources, and worksheets are below!
Civil Engineers design and build things in your community such as buildings, roads, and bridges. Civil Engineers make structures that are stable and safe for people to use. In this project, you’ll learn about designing, building, and testing the strength of a bridge using Spaghetti noodles, and then test the bridge for how much weight it can carry before collapsing.
Adult supervision when using Hot Glue Gun and Weights
1 package of dry spaghetti
Glue gun and pack of glue sticks
Variety of weights from 5 to 50 pounds
Tub or newspapers (to spread out under for easy clean up)
2 tables placed one foot apart
a few sheets of plain printer paper
Improve research and investigative skills
Learn design skills
Understand why testing is important for safety
Vocabulary Terms to Understand
Look up each word and write their definition on paper.
1. Print the Investigative Worksheet.
2. Watch the Instructional Video above, but don’t copy the bridge in it. Instead, you will create your own design.
3. Use the Internet to investigate different bridge designs and how they are built.
4. Use pencil and plain printer paper to plan a design for building your bridge.
5. After your plan is ready, build your Spaghetti bridge.
6. When completed, put the bridge over two tables that are about 1 foot apart.
7. Draw a chart on the back of your Investigative Worksheet to track how much weight your bridge can handle before collapsing. Start with the smallest weights.
What happens to the bridge when you add more weight to it?
What would you change in your design to make your bridge stronger?
