I enjoyed watching auto races as a child, so I decided to check out Norm Barstow’s session, Elastic Power: Wind Up Your Engines and Explore (a.k.a. “NASCAR in New Orleans”).
Preparing for the big race
Barstow had elementary and middle school teachers use an elastic-powered wooden car to explore energy transfer and force and motion.
Check out Barstow’s “lab coat”: No boring science lessons for his students! 
Start your engines…
I interviewed Barbara Park about her experiences in this session.
Great job> I will used this in science asap. Thanks
