Build Solar Cars (Lesson 3)
Students will construct a geared solar car, a pulley-system solar car, or both. Students will make verbal predictions about the outcomes and viabilities of different types of solar cars. Students will pinpoint the independent, dependent, and control variables in their solar car testing process.
Students will build their solar vehicles. There are many options for them to do this, depending on the specific variables hoping to be tested following the construction and material-selection process. Students will be given the opportunity to try out multiple sizes of gears or pulley systems in order to determine which type they hope to be racing in the following lesson plan and make verbal predictions about what exactly will take place when comparing the different iterations of vehicles.
