Gummy Bear Conclusions

Today students got to see what happened when gummy bears are soaked in water for 24 hours. They get huge! Students could see that the gummy bears were larger, but really had a good idea of the size change when they compared their big bear to a control, a normal size gummy bear.

Morgan's bear did not get bigger because he used the sink with hot water. His gummy bear dissolved!

Some students had difficulties measuring the gigantic bears because now they were more fragile and quite a few lost feet and some bears were just blobs. Students worked on their measurements and writing good conclusions.The gummy bears absorbed water and as a result gained in volume and became less dense because the particles moved further apart.
