Silly Science - making science a little more exciting and connecting it with reading through demonstrations
Age Range: appropriate for kids that know not to put things in their mouths
Books Promoted: various science experiment books on display
Supplies:
- Quicksand Goo a.k.a. Non-Newtonian Fluid ( 1 box cornstarch + water ) experiment link
- Bubbles ( purchased or made from soap + bubble wands or pipe cleaners )
- Soda Geyser ( 1 bottle soda + mentos ) experiment link
Total Program Cost: for me, approximately $12. price will vary, depending on how good a shopper you are and how many batches of goo and how many bottles of soda you’d like to explode.
Skills Promoted: Literacy through the use of an experiment. Scientific reasoning through guided experiments. Motor skills (gross and fine) by manipulating the quicksand goo and bubbles. Social through interactions with adults and peers.
Commentary
Science day was fun for the kids that came and it was pretty entertaining for some parents too. Either no one really likes science or it was just a really quiet day at the library. It was hot and I think that a lot of people were on vacation this week. Ah well.
So I borrowed a lab coat which was really way to big and dug up my googles from high school chemistry. Got to do the whole evil genius laugh and blew bubbles waiting for people to show up. Not a wonderful turn out but it was actually nice having a smaller group. I really need an easel because I really enjoy scribbling on things. Well, without an easel, I pretty much held up the things that I was using and described a little about how each thing worked.
We went outside because there is no way I’m exploding soda anywhere near the books and allowing cornstarch goo near the carpet. Bubbles… I had my test tube and blew a few, but just enough to attract people. Yeah, in retrospect, I should have done the whole program outside and done the experiment while explaining. Oh well.
Outside we went and I did the whole soda geyser first with a 20 ounce bottle of soda an just one mint. It was enough to satisfy the kids, but well… not me. Me: Bigger? Kids: Yeah! Me: Bigger! I dragged out a 2 liter complete with crazy evil genius smile. There’s quite a few youtube videos on this experiment though EepyBird has the whole fancy fountain display. According to Myth Busters, any soda with carbonation works, but apparently diet Coke works best thanks to the sweetner. Yeah, I read quite a bit about this experiment. I also didn’t want to spend the $6 for the test tube launcher and made my own. Take one large index card, roll into a tube around the roll of Mentos loosely and tape it. Punch two holes in the tube about a centimeter or so from the bottom so that you can look through one hole and see through the other. Fold a length of pipe cleaner in half and insert it through both holes. The folded end I pulled apart a bit so I’d have kind of a grenade pin deal. Throw the Mentos in the top part and shove the tube into the mouth of the bottle. Pull the pin and run! =) If you have a test tube, I think I read somewhere that you can fill it up and use an index card to control the drop.
After I did that, I let the kids have at the quicksand goo and the bubbles. Surprisingly, the quicksand goo was what the kids wanted to play with the most. A lot of the kids ended up playing with the bubbles after they were done because apparently a bucket of dishwashing liquid and water to make bubbles also is a nice rinse. Go figure. While they were in free play experiment mode, I went around to the different little groups and explained why things worked the way the did. That got quite a few kids interested and I answered questions.
It was an interesting program. When I needed to close up shop, I blew up two more bottles of soda only I dumped in like more Mentos. Beware having too many mints to drop in! Yeah, by the time they all filter in, you won’t have enough time to run and will be covered in soda. Still fun if you don’t mind getting sticky though. Not bad for a $12 program
A WORD OF CAUTION when cleaning up your mess. DO NOT POUR THE NON-NEWTONIAN FLUID DOWN THE DRAIN!!! The quicksand goo is totally bad for plumbing! It’s advised that you throw it into a plastic bag for the trash can. Yeah, I warned you and as it says in the disclaimer, it’s totally not my fault if you get it into your brain to try any of the crazy things I do!
