Coke vs. Diet Coke (It's not what you think)

4th grade students hypothesized what would happen when a can of coke and a can of diet coke were placed in a tank of water.  In order to make informed hypotheses, table teams investigated the soda cans, gathering as much information as possible.  This is what we came up with...

Here are some of the hypotheses:

"I think that the coke will immediately sink because, I weighed the cans and the coke weighed more, and the diet coke is going to float because it has less mass."

"I think that both will float in the water because they both have air in them."

"I think that the diet coke will float because it is more dense than the coke and the water."

"I think that the coke and diet coke will both sink because they both have a lot of mass."

We conducted the experiment and discussed the concept of density.  In order to find out the results, you must ask your child!
