Objective
By the end of this lesson, you will be able to understand the basic principles of physics related to cars.
Materials and Prep
- Toy cars (at least two)
- A flat surface to race the cars (e.g., a table or a smooth floor)
No prior knowledge is required for this lesson.
Activities
-
Activity 1: Racing Cars
Place the two toy cars at the starting line on the flat surface. Give them a gentle push to start the race. Observe and measure the distance each car travels before coming to a stop. Discuss why one car traveled farther than the other.
-
Activity 2: Changing Speed
Experiment with different ways to change the speed of the toy cars. For example, try pushing one car harder than the other and observe the effect on the distance traveled. Discuss how the force applied affects the speed of the car.
-
Activity 3: Weight and Distance
Add small weights (e.g., coins or small objects) to one of the cars. Repeat the race from Activity 1 and observe how the added weight affects the distance traveled. Discuss the concept of weight and its impact on motion.
Third Grade Talking Points
- "Physics is a branch of science that helps us understand how things move and interact."
- "Force is a push or a pull that can make an object move, change direction, or stop."
- "When we race the toy cars, we can see how the force we apply affects their speed and distance."
- "Weight is the measure of how heavy an object is. It can affect how far an object can travel."
- "By experimenting with the toy cars, we can learn about the basic principles of physics that apply to real cars."
