Encourage creativity in design and hold a race to determine the fastest car. Teachers may wish to involve their students in The Junior Solar Sprint competition. As a continuation of the previous discussion of motor vehicles, ask students to collect data for one week on their families' transportation by creating and completing a transportation log. Analyze and graph the collected data. Discuss ways that students and their families can reduce vehicle emissions and vehicle use in general.

Display maps and posters in the school. It is probably our oldest source of energy and is still the main source of energy for over half of the earth's population. Ask students to investigate the process of creating energy through biomass.
