4-H clover 4-H engineering design project

3 youth making parts

What problem do you want to solve -- cook a hot dog with the sun? Make a car run on wind power? Communicate with birds? Design a solution and build it. Learn engineering design skills and you'll know how.

What can you do?

In the engineering design project, you can design, build and test:

  • Model of a roller coaster.
  • Bottle rocket launcher.
  • Catapult or trebuchet.
  • How simple machines operate.
  • Model of a wind turbine.

These are just some of the many ways you can participate in this project.
