Math stuff and Gummy Bears

Today we discussed proper lab write-ups and started a new lab with Gummy Bears. The students measured and weighed the gummy bears to find mass, volume, and density. Then the gummy bears were put in a cup full of water for one hour to see what would happen. Students hypothesized that the bears would shrink and dissolve or the color would leak out or the bears would get squishier.

In the hour interim, students practiced identifying significant digits and reacquainted themselves with scientific notation.

After the hour, the bears were retrieved with difficulty for more measurements. There was a lot of complaining about not being able to grasp the bears because they were now much more slippery and slimy. Most of the bears did swell in size and become less dense... except for Kristina... she used hot water and her bear shrunk because it dissolved.

There's one more set of gummy bears hanging out in water til tomorrow. What do you think will happen to the bears overnight?
