Reflection: Intervention and Extension Hybrid Cars - Section 2: Activity

Students often like using data from internet sources. The US Department of Energy has an useful site that can be used to extend this activity:

http://www.fueleconomy.gov/feg/Find.do?action=sbs&id=34487&id=34486

Although it is not always feasible given the time available in the curriculum, I like to use the above website to ask my students to find another automobile model and conduct the same comparison that we completed as a class for the Toyota Avalon.

If time is short but the students seem engaged, I will launch an informal project by saying something like, "You seem interested in choosing your own car, why don't you use your graphing calculator to consider if a hybrid might be a more economical choice for a car that interests you."
