First – BONUS points if you know where that headline comes from and don’t just think I’m gettin’ my hillbilly on.
Second, when I’m neglecting this blog, it’s because I am furthering my education. And, believe it or not, I’m pursuing a teaching degree. I know, it’s hard to resolve that with the grammar horrors routinely committed here. Red lines and points off everywhere.
Sentence fragments! Rambling non-sequiturs! General overuse of clichés! Informal language everywhere! Gratuitous exclamation marks!
Where was I? Oh, yes.
This semester, I am taking Science for Elementary Teachers, which is all kinds of fun because the lectures on atomic theory and other serious things are punctuated with experiments involving noisy messy things. And the instructor, God bless her, is not at all phased when I get out my phone and say “hang on, I want to live stream this and maybe put it on the internet.”
So, last night, we learned about chemical reactions, and a fabulous experiment you can do tonight with your kids if they’re bored.
You will need:
- An empty film canister or one of those plastic canisters vending-machine toys come in.
- An Alka-Seltzer tablet
- A tolerance for some degree of messiness and squealing
You will fill the cannister about halfway with water, drop in half an Alka-Seltzer tablet, snap the lid on, flip the cannister upside down and stand back expectantly.
And this will happen:
Or perhaps this:
The education value in this is to teach Ideal Gas Law, and if you want to know about that and see a lesson plan, go here: Cool Science Lesson Plan. But I would recommend just trying this out with your kids on the next rainy day.
