I just finished watching video #7, and they had an activity that was similar to the Barbie doll activity. They use eggs to show inertia and the importance of seatbelts. I thought drawing a happy face on the egg that had the seatbelt and a sad face on the cracked egg that had no seatbelt was cute. It's a nice activity, because it's inexpensive enough that the whole class can participate, so you don't need to do it as a demonstration.

I'd use that activity as an introduction to a lab. For kids, http://auto.howstuffworks.com/airbag.htm is an excellent resource.

To show the usefulness of seatbelts, I use a Barbie doll car and a rag doll named Inertia. I have one of the students push the car, and another student stop the car as quickly as possible. When Inertia's legs are on top of the car, she continues forward and hits the child. When her legs are tucked under the car, she stops with the car. I do this activity as a demonstration, rather than a lab, because I only have one Barbie doll car.

To show the usefulness of airbags, you could do an activity like the egg drop. It's explained here:
http://college.hmco.com/education/pbl/project/project3.html

For an egg drop, you create a cushion around the egg, so that when it's dropped from a balcony or ladder, the egg will not crack.

forForce & Motion

Dear all,
 
For the second workshop, in the training guide there is a research activity relating to auto safety devices and how forces and motion play a role in their design. If this activity is given to students in class could it be considered a lab activity or would it be a research report? If you don't consider it a lab, any ideas on modifying the concept to make it a lab activity?
 
Regards,
Roberto Crespo
 
PS. I was a little skeptic about doing a course over the internet; however, so far I am very impressed with the workshop!
