Study the science of rocketry through a variety of hands-on experiments for all ages. Members conclude this project by building and launching 2-liter bottle water rockets. A bottle rocket launcher may be available from your county Extension office. Visit our website at ohio4h.org/rocketsaway. Note: Members wishing to launch solid-fuel model rockets should take 503.

Experiment with the forces of flight by building and flying a model airplane or glider to soar above the earth. This project does not include radio-controlled airplanes or helicopters.

Study the science of rocketry through a variety of hands-on experiments for all ages. Members conclude this project by launching a solid-fuel model rocket built from a kit only; no scratch building. Note: Members wishing to build and launch 2-liter bottle rockets should take 501.

This project is for members who have completed 503 Rockets Away!—Solid-Fuel Model Rockets and who want to continue to develop specialized skills like scratch building. Members of any age may complete this project, but they should have significant experience in rocketry (comparable to what is required for other advanced-level 4-H projects) and be able to plan and complete the project on their own with minimal supervision or assistance.

Youth build on skills learned in levels 1 and 2 plus learn measuring electrical usage, replacing electrical switches, and determining electrical loads. Youth also evaluate different bulbs and test for electrical power. Use the same book 1-3 years.

This unit introduces the basics of solid-state electronics and provides hands-on activities for practical experience in understanding modern day electronic equipment. This project can be taken after youth successfully completes 528 Investigating Electricity and has solid soldering skills and circuitry knowledge. Use the same book 1-3 years.

This beginning electricity project book includes 11 kid-friendly and time-tested experiments about static electricity, currents, electromagnetism, electric motors, and electric light. Each experiment has a brief introduction, a supply list, and step-by-step instructions that bring an electrical concept to life. Requires additional supplies.

Your kitchen becomes a laboratory as you observe and experiment with dairy products. As a member of the Dairy Police Task Force, discover the science behind butter, cheese, and curds while solving the mystery of The Missing Milk. After completing this project you are encouraged to explore other Science and Food and Nutrition project books.

Learn to make 14 different simple knots, bends, and hitches. Remember what they say—practice, practice, practice! Then show what you have learned with a capstone project of your choosing. Sample capstone projects are available at ohio4h.org/knots.

Let your inner scientist uncover the mysteries of physics at play in daily life. The amazing magician Franco Newtoni is your guide as you try each experiment. You’ll see the forces of nature, energy, and the power of physics at work—or is it magic? This STEM project will satisfy your curiosity on many topics!

Youth focus on basic small engine knowledge, study external engine parts, discover tools of the trade, and learn the concepts behind what makes small engines work. They explore the uses of small engines and safety issues. Use the same book 1-3 years.

Youth explore internal parts of engines, learn about engine sizes, compression ratios, seasoning their engines and safety issues. Youth also learn about occupational possibilities and about starting their own business. Use the same book 1-3 years.
