Objective

By the end of this lesson, the student will be able to understand the basic workings of a car motor and its components.

Materials and Prep

• Paper and pencil
• Internet access or books about car motors

Activities

• Draw and label a car motor: Have the student draw a car motor and label its different parts, such as the pistons, cylinders, spark plugs, and crankshaft.
• Research different car motors: Ask the student to use the internet or books to find information on different types of car motors, such as gasoline, diesel, or electric motors. Have them write down three interesting facts about each type.
• Build a model car motor: Using materials like cardboard, straws, and rubber bands, guide the student in constructing a simple model car motor. Explain how each component works together to make the motor run.
• Identify car motor components: Show the student pictures of different car motor components and have them match the pictures with their corresponding names. This can be done as a simple matching activity or as a scavenger hunt around the house, looking for car motor parts in different objects.

Talking Points

• Pistons: "Pistons are like the arms of the car motor. They move up and down inside the cylinders, helping to create power."
• Cylinders: "Cylinders are like the rooms where the pistons move. The more cylinders a car motor has, the more power it can produce."
• Spark plugs: "Spark plugs are like the matchsticks of the car motor. They create a spark that ignites the fuel and air mixture inside the cylinders, making the pistons move."
• Crankshaft: "The crankshaft is like the heart of the car motor. It converts the up-and-down motion of the pistons into circular motion, which makes the car's wheels turn."
• Gasoline, diesel, and electric motors: "There are different types of car motors. Gasoline motors use gasoline as fuel, diesel motors use diesel fuel, and electric motors use electricity to power the car."
