Mechanical Engineering of Cars
About this free Mechanical Engineering of Cars course
Mechanical Engineering of Cars is a free engineering course that uses cars to explain core mechanical engineering ideas. Students go under the hood to learn how an engine turns fuel into motion, how a car breathes air in and pushes exhaust out, how suspension keeps the ride smooth, and how aerodynamics affects speed and efficiency.
Short videos, like Heart of the Car and Lungs of the Car, introduce each system. In hands-on projects, students design, build, and analyze car components themselves, and they explore how cutting-edge technologies are shaping the future of transportation.
Who this course is for
The course is designed for students in grades 6 through 10 who are curious about cars, engineering, or how machines work. No prior experience is required.
Course outline
- Let's talk cars. An overview of the major systems in a car and how they work together.
- Heart of the car: the engine. How an internal combustion engine converts fuel into motion.
- Lungs of the car: intake and exhaust. How air flows into the engine and exhaust flows out.
- Suspension. How springs and shock absorbers keep tires on the road and passengers comfortable.
- Aerodynamics. Drag, downforce, and why car shapes matter.
- The future of transportation. How new technologies are changing the way cars are designed.
What you'll learn
- Name the major systems of a car and describe what each does
- Explain how an engine converts fuel into motion
- Describe the roles of air intake, exhaust, and suspension
- Explain how aerodynamics affects speed and efficiency
- Apply mechanical engineering thinking to design a car component
How long it takes
The videos are short, a few minutes in total, so most of the time goes into the slides and projects. Plan on about 4 hours.
Frequently asked questions about Mechanical Engineering of Cars
Is Mechanical Engineering of Cars really free?
Yes. Mechanical Engineering of Cars is completely free, with no fees, subscriptions, or account required. STEM for Others is a 501(c)(3) nonprofit, and every course in our curriculum library is free for students, families, and teachers.
What is mechanical engineering?
Mechanical engineering is the design of anything that moves, such as engines, machines, robots, and vehicles. Cars are a perfect example because they combine forces, energy, heat, and motion in one machine.
How do I start the course?
Click Begin Course at the top of this page to open the lesson slides, and watch the short companion videos on the STEM for Others YouTube channel. Pause after each topic to sketch or build the car component you just learned about.
Do I get a certificate?
The self-paced Mechanical Engineering of Cars materials don't include an official certificate. If you're taking the course through a STEM for Others chapter program, ask your chapter leader about recognizing your completion.
Can teachers and clubs use this curriculum?
Yes. Teachers, homeschool families, libraries, and after-school clubs are welcome to use the Mechanical Engineering of Cars materials with their students at no cost. STEM for Others volunteers also teach our curriculum in partner schools and libraries. You can find a chapter near you or start one at your school.
