IQ Key Kits: Building Moving Machines
IQ Key kits let you build machines that can move! The kit comes with many parts that you can connect in different ways to make all sorts of machines.
Each part has a job. Look closely at the clear capsules. How do the parts fit together? Some connectors might be too tight or loose. If you can’t take off a connector, don’t twist it off! Use the wrench that came with the kit to pull it off. If it’s too loose, use a small piece of tape to make it fit better.

How Machines Move (Mechanical Energy)
How Machines Move (Mechanical Energy)
When you add batteries to the IQ Key machine, the energy in the batteries changes into electrical energy. The motor takes this electrical energy and turns it into mechanical energy, which makes things move.
For example, if you want all four wheels of a car to move, you need to transfer energy from the motor to each wheel. You can do this with gears and shafts.
Understanding how energy moves through the system is important when building machines.
What is Torque?
What is Torque?
Torque is the force that makes things spin. Imagine using a wrench to tighten a bolt. You apply torque by turning the wrench around the bolt.The farther from the bolt you push, the stronger the torque. The formula for torque is:Force x Distance = Torque
Work and Energy
Work and Energy
When you push or pull something and it moves, that’s called work. The amount of work depends on how far the object moves.
Force x Distance = Work
Work is a form of energy, and it’s measured in joules (J). One joule is the energy used when you apply a force of one newton to move something one meter.
