Wheel & Axle Tractor

Students study and identify different types of simple machines and how they work. They design a simple machine.

Students identify simple machines and how they must work together to form a piece of equipment used in agriculture. They create a diagram of a piece of farm equipment and write about two of the simple machines they drew.

Students research and conduct experiments with several types of simple machines. They examine levers, pulleys, inclined planes, wheels, axles, wedges and screws and then consider the physics behind "Green Eggs and Ham".

Students research aerodynamic design. In this aerodynamic design lesson, students investigate wind resistance on a car. Students explore the reasons necessary for aerodynamic design.
