Match the following types of simple machines with their purposes:

Inclined plane = Reduce force needed to lift objects Wheel and axle = Transfer force from one point to another Lever = Change the direction of the applied force Pulley = Multiply the force applied to lift objects

Match the following simple machines with their functions:

Stapler = Apply a single downward force Wheelbarrow = Transfer heavy loads with less effort Scissors = Cut materials using two blades Screwdriver = Turn screws to fasten or unfasten objects

Match the following simple machines with their descriptions:

Wedge = Two inclined planes put back to back Gear = Toothed wheel that meshes with another toothed wheel Axle = Rod that connects two wheels for rotation Cam = Rotating piece that pushes against another part to create motion
