Objective

By the end of this lesson, you will understand the basic principles of how cars work and the science behind their engines.

Materials and Prep

• Toy car or model car
• Pen and paper for notes
• Access to the internet for research

No prior knowledge needed. Just bring your curiosity and enthusiasm for cars!

Activities

• Research the history of the internal combustion engine and how it powers cars.
• Take apart a toy car or model car to see the different components inside.
• Design your own car engine on paper, labeling the key parts and explaining how they work together.

Talking Points

• How does a car engine work?
  "A car engine works by burning fuel inside cylinders to create controlled explosions that drive pistons up and down."
• What is horsepower?
  "Horsepower is a unit that measures the power of an engine. The more horsepower, the faster a car can go."
• Why do cars need oil?
  "Oil lubricates the moving parts of the engine and helps reduce friction and wear."
• What is the role of the transmission in a car?
  "The transmission helps control the power from the engine to the wheels, allowing the car to change speed and direction."
• How do brakes work in a car?
  "Brakes use friction to slow down or stop the car by pressing brake pads against the wheels."
