Lesson Overview

In this lesson, students will complete a virtual lab in which they compare and contrast virtual racecars. By changing key variables related to vehicle performance, such as the kinds of engines or the kinds of energy sources used by the racecar, students will have a better understanding of the decisions they will need to make when designing their own efficient vehicles. Students will also learn about the pros and cons of alternative energy sources such as biodiesel, ethanol, and hydrogen.

Lesson Objectives
By the end of this lesson, students should be able to:
  • Identify the battery as the source of energy for a remote-controlled car.
  • Identify additional sources of energy for vehicle motion.
Lesson Essential Questions

1. What is the energy source in a vehicle and what is the energy receiver in a vehicle?
2. What are possible sources of energy for a vehicle?

Racing RC Cars

Virtual Lab Racing RC Cars What is the best combination of factors to make an RC Car go fastest or farthest? Students experiment with different motors, batteries, and car weights to find out.

Machines

Video Segment Machines A cylinder, piston, and crankshaft are parts often found in motors. Some machines need motors to perform. A machine is any mechanical device that helps you do work.
