Learn about the safety, fuels, maintenance, restoration and operation of tractors, small engines, machinery, automotive and marine engines and components.
What can you do?
In the mechanical science project, you can:
- Restore or modify an engine, vehicle, tractor, machine or implement.
- Explore how an aspect of a machine or a piece of equipment operates.
- Learn the history, purpose, technology or design of a machine or a piece of equipment.
These are just some of the many ways you can participate in this project.
What does it mean to show at the fair?
For 4-H'ers, local and state showcase events (like the Minnesota State Fair) are not just fun events. They provide youth opportunities to exhibit the knowledge and skills they've gained throughout the year– and to continue their learning.
Contact your local 4-H office for mechanical science (auto/marine, tractors and small engines) project showcase opportunities near you.
