ACTIVITY in Renewable Energy, Electricity, Redox Reaction, Galvanic Cells, Cathode, Anode. Last updated September 18, 2019.

Summary

In this activity, students will watch a video and answer related questions about the chemistry of batteries as they are used to power hybrid and electric cars. Students will learn about the basics of electricity, as well as how batteries function as a source of electricity.

Grade Level

High School

Objectives

By the end of this activity, students should be able to

  • Provide a basic overview of the differences between a hybrid or electric vehicle and a car that is powered by fossil fuel.
  • Describe the flow of electrons in a lithium battery in order to generate electricity.
  • Identify the meaning of the terms, anode and cathode.
  • Differentiate between oxidation and reduction.

Teacher Notes

  • The Hybrid and Electric Cars video was developed as a part of the 2016 AACT-Ford, Chemistry of Cars content writing team project, sponsored by the Ford Motor Company. The entire video series can be found here.
  • Additionally, 19 lesson plans related to the Chemistry of Cars theme were developed by the content writing participants. You can learn even more about this project by reading an article from the September 2016 issue of Chemistry Solutions, written by the lead teacher involved in this project.
  • The running time of this video is approximately four minutes.
  • This video is intended for students to watch, and for teachers to integrate into their curriculum.
  • The student questions/answers are presented in sequential order in the video.
  • An answer key has also been provided for teacher reference.
  • Videos can be shown with the use of a classroom projector, or teachers can generate a Student Video Pass through their AACT membership to allow students to independently access the video.
