The Ultimate Bubble Blowing Champion

IMG_1516

Today’s my last day of winter break. I’m sure my students are just as excited to go back as I am (and are also secretly hoping for a snow day). That first day back is always a tough one. They (and I) have been staying up late and sleeping in for two weeks. With all those visions of sugar plum fairies dancing in our heads, there’s little room for biology. And BAM! We’re back to school.

I give me freshman a pretty easy transition back to class. We have a bubble blowing contest. But it’s not all fun and games…. they have to do a lab report. It’s a great way to review concepts we used last semester (ie. control variables, hypotheses, graphing) and get them a little sugared up to get through the day. Here’s the lab template my kids use:   Lab Write Up Template  They have this glued in to their lab notebooks so that it cannot get lost. Usually they write their reports on a separate paper but I think I’m going to have them type them on a GoogleDoc and share it with me this time.

I go to the dollar store and buy a bunch of different types of gum. Then I put them in groups of 2 or 3 and each group has to come up with their own hypothesis. Some will test different types, some different people. I even have had groups test the number of chews before blowing a bubble. Once each group has figured out how to blow their biggest bubble, the groups compete for the title of Ultimate Bubble Blowing Champion!

Last year's winner!

So simple  and they have a lot of fun with it. Try it for yourself! Have other activities for the post-winter break blahs? Share them in the comments!
