Objective
By the end of this lesson, you will be able to understand the basic principles of physics related to race cars and apply them to real-life situations.
Materials and Prep
- Paper and pencil
- Access to a computer or mobile device with internet
- Printouts of race car images (optional)
No prior knowledge or preparation is required.
Activities
-
Research Race Car Physics
Use the internet or books to research about the physics principles involved in race cars. Take notes on important concepts such as aerodynamics, friction, and forces.
-
Build a Race Car
Using your knowledge of race car physics, design and draw your own race car on paper. Consider how different shapes and features can affect its performance. Be creative!
-
Experiment with Friction
Find a smooth surface at home, like a table or floor. Place your race car on it and give it a gentle push. Observe how far it travels before coming to a stop. Now, add some weight to your race car (e.g., small books or coins) and repeat the experiment. Record your observations and explain how friction affects the car's motion.
-
Create an Aerodynamic Design
Using the principles of aerodynamics, modify your race car design to make it more streamlined. Cut out different shapes from paper and attach them to your car to see how they affect its speed. Test your modified race car by blowing air at it and measuring how far it travels. Keep track of your results and explain why certain shapes are more aerodynamic than others.
Fifth Grade Talking Points
- "Race cars are designed to go really fast. They need to be able to move quickly and safely."
- "Aerodynamics is an important concept in race car design. It's about how the shape of an object affects its movement through the air."
- "Friction is the force that opposes motion. It can slow down or stop an object."
- "Different shapes and features can affect how well a race car performs. Engineers use their knowledge of physics to design cars that go fast and handle well."
- "By experimenting with different designs and understanding the physics behind race cars, we can make our own models that perform better."
