What's Up in the Environment?
OVERVIEW | procedures

Class Projects   Solar Cars


Introduction

Students are probably aware that energy sources and their impact on the environment are important issues. To cut down on our dependency on fossil fuels, scientists have turned to renewable sources of energy. Solar energy has long been lauded as the possible solution to the energy and pollution crisis.

In this project, students investigate the amount of pollution produced by cars and how solar energy might alleviate this problem. By creating their own car students will investigate how solar energy can be used, and learn about some of the challenges involved with building solar powered cars.

This project incorporates elements of the scientific method.

Grade level
Middle school, but can be adapted to suit other grades

Time allotment
Up to 1 semester

Subject matter
Main focus on environmental science, with language arts and social studies connections

Learning objectives
Students will:
  • Research the causes and effects of air pollution.

  • Investigate the specific effects of carbon dioxide on the environment.

  • Learn the benefits of using solar power.

  • Learn about renewable energy technologies and their environmental benefits.

  • Gain an understanding of the scientific method and use elements of it to conduct steps of the project.

  • Build a model solar car to see solar energy in action.

  • Use technology to research and synthesize information.
Standards
  • North American Association for Environmental Education (NAAEE)
    Excellence in Environmental Education: Guidelines for Learning
    http://naaee.org/npeee/learner_guidelines.html
    Strand 1-Questioning and Analysis Skills (Guidelines A, C, E, F, G); Strand 2.1-The Earth as a Physical System (C); Strand 2.3-Humans and Their Societies (A, C, D, E); Strand 2.4-Environment and Society (A, C, D, E); Strand 3.1-Skills for Analyzing and Investigating Environmental Issues (A, B, C); Strand 3.2-Decision-Making and Citizenship Skills (A, B); Strand 4-Personal and Civic Responsibility (B).

  • Technology Foundation Standards for Students
    http://www.iste.org/standards
    Standard 1: Basic operations and concepts; Standard 2: Social, ethical, and human issues; Standard 3: Technology productivity tools; Standard 4: Technology communications tools; Standard 5: Technology research tools; Standard 6: Technology problem-solving and decision-making tools.

Assessment
Students will research, build, and modify a solar-powered car, documenting what worked or failed along the way. After reaching a final design, students may enter their solar car in a local competition or possibly the competition held by the U.S. Department of Energy's National Junior Solar Sprint program. Their findings will be captured in a presentation such as a scrapbook, PowerPoint file, or Web site.
