Box Car Derby: A STEM Project for Practical Equation Solving
A Hands-On STEM Challenge That Makes Algebra Feel Useful
Box Car Derby is a hands-on STEM project where students design a small derby car, work within a budget, apply basic physics equations, and use data to reflect on which designs performed best.
Our box car derby math project gives students a reason to care about equations, measurement, and physics. Instead of solving isolated problems, they design, build, and test a cardboard car while using math to support decisions.
Suggested Grade Level: 7–10 (Algebra 1 math skills)
Best for: Basic Physics Equations, Measurement, Engineering Design, Data Analysis
How This Box Car Derby STEM Project Works
Students act as designers and engineers as they transform an ordinary cardboard box into a derby car built for speed. They submit designs, “purchase” materials within a budget, build their car, and test it to see how well it performs.
Along the way, students use algebra skills to manipulate basic physics equations, measure carefully, and reflect on how their design choices affected the final results.
What Students Do
- Design a derby car using simple materials
- Work within a set budget to choose parts and materials
- Build and test a cardboard racer
- Use measurement and basic physics equations to analyze performance
- Reflect on the design process and explain what worked best
Skills Students Practice
- Manipulating and calculating with basic physics equations
- Measurement and precision
- Engineering design and revision
- Analyzing results with data
- Reflective writing and evidence-based conclusions
Why This STEM Project Works
Hands-on math takes center stage in this project because students can immediately see the effect of their choices. They are not just solving for a variable. They are trying to build the fastest car.
That mix of construction, competition, and practical equation solving makes the math feel much more alive. It also creates a strong bridge between math, science, and engineering.
When to Use This Project
- During an Algebra 1 unit involving formulas or equation solving
- For math and science collaboration
- As a STEM project week challenge
- For hands-on enrichment or performance tasks
- Anytime students need to see practical equation solving in action
