What you'll do
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.

Fairs and exhibits
Engineering design covers a broad range of topics and objects. Judges will look at how well you have applied the engineering design process.
Some ideas
You could design, build and test a:
- Hand that can grab items
- Water filtration device
- Musical instrument
- Model of a roller coaster
- Model of a bridge
- Bottle rocket launcher
- Catapult
- Goat milking stand
- Model of a wind turbine
- Rubber band car
- Solar oven
- Rube Goldberg-type Machine
- Wave-powered device to recharge boat batteries
- What a judge is looking for (project evaluation sheet)
- County fair judging - what's that like? (video)
Record keeping
Some counties require record keeping for fairs.
Resources
The Engineering Design Process -A key way to learn about engineering design is to use the Engineering Design Process (EDP). The EDP is a cycle of individual steps that can be used in either a sequential order or a mixed order and be repeated as many times as needed. Applying the steps to creating solutions guides learning and provides a “roadmap” to the problem-solving process.

Future study and careers
You could study engineering. There are different kinds of engineers -- electrical, civil, mechanical and biosystems engineering, to name a few.
You could study design products, clothing, landscapes, building interiors and more.
If it wasn't designed by mother nature, it was probably designed by a designer or an engineer. They dream up and make possible most objects we use in modern life.
