Full of Hot Air

I can't believe it's finally here, but today was the first day of Super Saturdays! As I mentioned in a previous blog, I'm teaching a series of 2-hour science classes at the Salem-Keizer Education Foundation this summer. The first class was called "Full of Hot Air" and we built balloon-powered cars.

There were 11 kids that showed up - 8 boys and 3 girls. Most of them had just finished 4th or 5th grade but there were a few older and younger. The kids were really eager to get started. I had all the supplies set out and I think I've learned that that's not a great plan for next week! I barely had a chance to tell them what we were doing and they were cutting stuff up and gluing stuff together!

Some of the kids got very inventive after trying their car with one balloon and finding it anti-climactic. I think by the end of the 2 hours most of the kids were powering their cars with 2 or 3 balloons, or as shown in the first picture - 4!

I set up a "racetrack" in the hallway before the class started by marking
off every foot with a short line and every yard with a long line. The kids used this space to try out their cars and see how far they could get them to travel. I few got theirs to go beyond the original 25 feet I had marked, so I had to add extra markings to the track!

And of course, some decided to race their creations at the end!

The room was a total mess when they left. I spent about 30 minutes cleaning it all up. Might have to do something about that next week. :)

They all seemed to have fun and none of them were terrors, so all in all I'd say it was a success. Next Week: propeller-powered cars.

It sounds like the first class was a success! I'm sure they all had a good time. A few adjustments to your procedures next week will probably make your job a little easier. Good job! I hope your next week's group will be just as cooperative and creative.
Love you!!! MOM
