Today we will be switching it up, and doing an experiment that comes from the branch of science called biology. Biology is the study of living organisms. It may seem a little silly, but this lesson is going to start with an experiment about gummy bears! We’ll do the experiment and then learn about the principle that is at play and learn how it’s related to biology. Before starting the experiment, we’re going to do a quick refresher on how to measure using a ruler.
Materials: A few gummy bears, a cup of water, a ruler*, the shared GoogleDoc, a timer
[Note: if you don’t have a ruler, you can print one from here. If you don’t have a printer, you can use it to trace. For the GoogleDoc, just click “the shared GoggleDoc” above, and it will take you there.]

You won’t understand all of the terms, but it’s entertaining and a great way to be introduced to more complex science concepts.
