Overview
With this kit, you will learn how to design and build machines with motors and gears. First, you will build a spin art machine that you can use to make splatter paintings and spiral designs with magic markers. In addition to creating cool artwork, this project will help you learn how to build a gear drive and to learn about gear ratios. Mechanical engineers need to know about the key parts needed to build machines, and understand how to design gear drives (which are just one type of power transmission a machine could have). They also need to understand some important science ideas that determine how well their machines will operate: such as torque (rhymes with fork), inertia (say “in-ur’-sha”), acceleration, and balance. You too will learn about these ideas by doing experiments with your spin art machines. These ideas sound complicated, but you will see that they really are not. And why would you want to learn all this stuff anyway – so you will be able to design and build your own motorized inventions. To make an electric pencil sharpener, you need to know how to build a gear drive with A LOT of torque in order to shave the wood off pencils! For your final challenge, you will design and build your own electric mixer to make pudding, Kool-Aid or yogurt smoothies!
