Mad Machines

Mechanics make our everyday life easier by overcoming friction!

There are six different kinds of simple machines, and that they all help make tasks easier. Some examples of simple machines include hammers, forks, wheels, tweezers, scissors, teeter totters, screws and wheelbarrows. Experiment with catapults using spoons and Koosh balls. A screw is a useful tool for holding things together.
Wedges can be used to push two objects apart. A pulley device can make lifting things a lot easier. Wheel and axles work together to get things moving.
