Project #5

K'NEX Building Levers

​

CORE CONCEPTS USING K'NEX

• A lever is a simple machine.

• Levers make work easier by reducing the amount of force needed to do a job.

• A lever has three parts: a load (the work we want to do), a fulcrum (balance/pivot point for the lever), and effort (the force we use).

Circuit Maze

CORE CONCEPTS FOR CIRCUIT MAZE:

​

• Short Circuit- An electrical circuit that allows current too much current to flow which can be dangerous to the parts or people using the circuit.

• Closed/Complete Circuit- A circuit without interruption that allows current to flow on a continuous path.

• Open/Broken Circuit- A circuit in which the continuity is broken so that the current does not flow.

K'NEX LEVERS

POP students are presented with a challenge to learn how simple machines work by building levers with K’nex. 

​

What do seesaws, wheelbarrows, and scissors have in common? They are all simple machines that use levers to make work easier.
