There are lots of things you can do with gummy bears. Eat them…Eat some more of them…Umm, put them in your mouth and chew and swallow them…Okay, maybe there’s just the one thing. But it’s a pretty great thing!
Today we’re going to add a second thing to that first thing. Because today we’re going to use gummy bears in a little science experiment that will help us learn how water behaves. Get your gummies ready!
- Small Bowl
- 2 Gummy Bears
- Paper towel
- A ruler
- Choose a gummy bear.
- Give it a name and a backstory. Is it Ricardo, the swashbuckling pirate gummy bear? Elizabeth, the firefighting gummy bear? You’re going to be with this bear for a while so you might as well give it some personality.
- Plop Ricardo or Elizabeth or Steve or whoever into your bowl, and then fill the bowl partway up with water. Measure how deep the water is with your ruler, being very precise, and either memorize it or write it down somewhere.
- Not much is happening yet, so now is a perfect time to make some observations. What does your bear look like? Were there any immediate changes to the bear or the water?
- Make a prediction: what do you think will happen to your bear if you let it sit in the water for a few days? Why do you think that?
- Now, let your bear sit in the water for a few days. Check on it at least once a day. Observe what changes, if anything.
- On day 3 or 4, go ahead and pull your bear out and set it on a paper towel. Grab a second gummy bear and compare. What is different about your water bear when you compare it to a bear that has stayed dry (by the way, we call that bear a “control”)?
- Measure the water left in the bowl. Is it different from the amount that you had initially? If so, where do you think that water went?
- Answer some of these questions:
Do your gummy bears have bubbles on them?
Are they larger?
Did they change the color, or smell, of the water?
Do they float, and did they before?
Can you see through the gummy bear?
How do they feel? Do they bounce?
