Are You Into It?
The Mechanics & Design project examines a range of areas linked to practical applications of power, energy, and electricity as well as structural and mechanical engineering. The project includes practical applications based on understanding the basic principles of these fields. Experience the technology firsthand while increasing technical and scientific literacy, communications and decision-making skills.
- Develop an interest in and understanding of science, engineering, technology and the basic principle and theories underlying technologies’ use of power, energy and electricity, as well as structural and mechanical engineering.
- Develop problem solving and logical reasoning skills.
- Improve communication and teamwork skills by working the way scientists and engineers do - in teams.
- Develop responsible attitudes about science and technology and how they relate to the real world and people’s lives.
- Gain experience in problem solving and decision-making using science process skills.
- Develop knowledge and skills related to the design, construction, and repair of structural and mechanical technologies.
Here’s what you can do all year!
Starting Out Basic / Level 1
- Learn about safety and equipment used in welding, engines and motors
- Learn about electricity and electronics
- Identify and distinguish between small engines and motors in your home
- Discover how engine work and how they are used in different machines
Learning More Intermediate / Level 2
- Learn about different methods of welding and what materials they are for
- Learn the different types of circuits and how to construct each type
- Learn about the parts of your lawn mower and how to make adjustments to its systems
- Diagnose an engine problem how to repair it
Expanding Horizons Advanced / Level 3
- Experiment with different welds and beads for joints for constructing a product
- Discover how electrical systems supply power to your home
- Restore, repair, or modify an engine or drive system of a tractor
- Design and build a machine to address a need in your home or farm

Fair Exhibit Tip Sheets
Tip sheets are used by judges to evaluate your exhibit. Use them to help make the best presentation of your work. Choose a tip sheet based on your project's intended purpose.
If your project:
- Represents a constructed, repaired, or restored item—use Mechanics & Design Tip Sheet (pdf)
- Is intended to inform its audience about a topic—use Poster Exhibit Tip Sheet (pdf)
- Represents an engineering solution to a problem—use Engineering Exhibit Tip Sheet (pdf)
- Represents a scientific investigation of a question—use Scientific Investigation Tip Sheet (pdf)
- Uses technology to accomplish a task or render a service—use Using Technology Tip Sheet (pdf)
Other Opportunities to Explore:
- Visit companies that have mechanical departments and use online mechanics simulations to learn more
- Start a “Fix This” competition in your club or county or host an antique tractor show
- Explore apprenticeships and internships to learn more about career options or start your own business using what you’ve learned about mechanics
- Contact your county ISU Extension Office for other local workshops, activities, and eventsrelated to mechanics or engineering design.
- Meet others interested in mechanics and design. Check out camps at the Iowa 4-H Center.
- Here are other opportunities to explore. National Youth Science Experiment.
- Study an area of environmental science and enter the State Science + Technology Fair of Iowa.
- Is it county fair time? Consider taking an exhibit, a piece of your project learning to the fair for judging and to show off what you have learned throughout the year. It might get selected to go to the Iowa State Fair.
- Attend Iowa 4-H Youth Conference and participate in workshops, motivational speakers and a community service project, bringing ideas back to your community.
- Interested in a college education in fields related to mechanics or engineering? Schedule a visit with Iowa State University to explore those majors.
