The Pine Car Derby Project is a fantastic, 2 week lesson, we used when teaching 6th grade math. This lesson capitalizes on students kinesthetic and visual interests, using Pine Car, and teaching them about distance, speed average, hypothesis and the scientific method. Students build their cars, test them on the track, record data, modify their cars and retest. Students than answer short questions about the data collected and information learned. This lesson also contains a presentation in prezi that is already formatted and viewable at the click of a button. We've done this unit at the end of the year multiple times and the students always absolutely love it. This lesson could also be easily adapted for any grade level and difficulty.
This lesson does not include a template for pine cars or a test track.
