Bridge Strength Test Spaghetti Engineering Project

There are a lot of engineering activities for kids out there, but not all of them are easy. If you have spaghetti in your house (or any dried, long noodle), then you already have everything you need to create the spaghetti engineering project!

Today’s project is extremely simple, yet teaches some important information about engineering, construction, and critical thinking skills. That’s why it is one of our favorite no-prep STEM challenges!

This project just goes to show that you don’t have to have fancy tools or a lot of elaborate planning or set up to help kids unlock the STEM side of their brains!

Teach kids all about structural engineering in this simple spaghetti engineering project! Teach structural engineering with this fun no-prep engineering challenge.

How to Do the Spaghetti Engineering Project

Follow along with these directions to learn how to set up your own spaghetti engineering activity for kids in elementary school.

There are a lot of structural engineering concepts that you can teach children just with plain dry spaghetti noodles.

How to Set Up the Spaghetti Engineering Project

All you need for this project is some dry spaghetti, some cans or books, and something heavy to put in the center of the bridge.

Before starting the project, ask the students if they think spaghetti is strong, and how many pieces of spaghetti it will take before it can hold up the weight of a can. Have the students record their answers in their STEM notebooks.

Spaghetti Bridge Engineering Challenge

Teach structural engineering with spaghetti! Just 2 simple materials are needed for this spaghetti engineering project!


  • Dry spaghetti noodles
  • Large soup cans (1 per group of kids)
  • Books or cans for the sides of the bridge


  1. Have the kids test the strength of one strand of spaghetti. Then keep adding strands until the kids can no longer break the spaghetti noodles. Have the students record how many noodles they could break in their notebook.92EE39A5 2BEA 4DF3 AD46 A1DA97CF9C09 scaled
  2. Have the children hypothesize how many noodles it will take to hold up a large soup can.

  3. While the children are completing the strength, test, talk about how many materials used in manufacturing are layered and work together with multiple parts to increase the strength of various items.
  4. Divide the kids into groups of 4-5 and have them build their spaghetti bridges. spaghetti bridge
  5. Have the children record how many noodles it took to hold up the can.
