Beakman explains that steam has a lot of power behind it and that a man named Hero in Ancient Greece figured out how to use it to make a ball spin. However, it wasn't until the invention of the steam engine that people knew how to use steam. Beakman uses a model to explain how the steam moves the piston back and forth to turn a wheel, which is how steam engine trains work.
A ship captain instructs his crew to bring the ship to full speed. This clip is a great view of the integration of machinery and manpower in a steamship.
Beakman explains Newton's Third Law of Motion and plays a video that offers some examples of it in action. Then they conduct a demonstration of the law using a balloon and a toy car.
Beakman explains how a helicopter has a rotating wing on top that helps it stay up because of the air pressure difference created by the shape of the wing. Then he explains that the back propeller helps steer the helicopter.
Beakman explains how gas is explosive and causes the combustion engine in the car to work. He uses a model engine with a side view and demonstrates what is happening with the gasoline when it explodes to move the engine parts. Beakman shows how the engine allows the wheels to turn by relating it to riding a bike. Up and down motion of the pedals is converted to turning the wheels through the chain. Same in the car with the pistons turning gears and thus the wheels.
