# Simple Machines

•What was the point of this activity?
Introduce students what simple machines are and what their functions are.
•Explain how you would introduce this to your class.
Demonstrate and explain what the 6 basic simple machines are. Ask students if they have seen any simple machines around the park, school, or even home. Then, I will demonstrate and show what simple machines each student is making. In groups, students will create their own simple machines.
•Where do you see a student having difficulty with this?
– Confusing the simple machine functions with certain objects.
•What changes or extensions could you do to this activity?
– Ask students to go around the room and write down objects that may be considered as simple machines.
Scientific Principles:
The 6 basic simple machines are the lever, the wheel and axle, the inclined plane, the wedge, the inclined plane, the wedge, the pulley, and the screw. The lever is a long rod that is placed under an object to lift it. Some examples are door handles, crowbars, claws from a hammer. A wheel and axle is a rod and a pole centered in the wheel to allow movement. A few examples are a bicycle wheel and pizza cutter. An inclined plane is a ramp that allows things to move from a low point to a high point and vice versa. A wedge is two inclined plane, however, it is used to separate two objects apart. For example, an axe is used to split a log in half. A pulley is a wheel and axle combined with rope and chain; it reduces the amount of work to lift an object. An screw is simply a twisted inclined plane. It allows the movement from lower to high in a circular motion such as lids and a faucet.
