 4-H MECHANICAL SCIENCES
Model Airplanes
Learn about the parts of a plane and tools for model building,
as well as how to build, test and fly models.
Model Rocketry
In this project you will learn about the history of rocketry,
understand the basic parts of a model rocket, make and fly your
own rocket, and learn about model rocket safety.
Bicycle Project
Learn how to identify the parts of a bicycle, follow bicycle
rules, handle emergencies and hazards, determine your reaction
time and ride safely.
Electricity
In this project you will learn the fundamentals of electricity
and explore the relationship between magnetism and electricity.
Learn about current and voltage, conductors and circuits while
you build a magnet, buzzer or electric motor. Study home electrical
systems and how to use them safely. Build your own electrical
mechanisms for use.
Circuitry
This project teaches you how basic electronic components "process" electrons
to form basic electronic circuits. It describes the workings
of radio, TV, other communication devices, computers, photo tubes
and radar. You will build several types of simple radios, microphones
and other basic electronic equipment from scratch.
Computers
In this project, you will learn how computer software and hardware
operates, how to program a computer, and how to make projects
using a computer.
Small Engines
This project covers small engine parts; principles of operation,
carburetion, care and maintenance; trouble shooting; preparing
an engine for storage; and small engine safety.
Scale Models
Learn how to assemble and create scale models of trains, trucks,
cars, ships, motorcycles, submarines and tanks. This project
describes how to obtain the materials you need, paint your model,
display your model and how to judge it.
Tractors
This project, recommended for ages 12 and over, covers the many
parts of a tractor, from nuts and bolts, to the instrument panel.
Learn about tractor safety, engine oil, mixing fuel and air,
how to give a tractor regular maintenance, safety checks and
safe driving.
Woodworking
Learn how to trace patterns, measure, mark, cut, nail, glue,
sand and finish while making projects from wood. Use power tools,
identify wood types and make your own patterns.
Off-Highway Vehicle
Discover the proper ways to enjoy the outdoor activity known
as OHVing! Off highway motorcycles (dirt bikes) and all-terrain
vehicles (ATVs) can be an enjoyable group experience. In this
project, safe and responsible riding habits will be established.
Whether you own an OHV now or would like to know more about them
before deciding if you should get one, this is the project for
you!
