It is no secret in my class that I like to drink diet coke from a bottle versus a can (mainly because I fear things falling into the open can). I also like my diet coke SUPER COLD. The other day I grabbed one from Walmart and thought to myself, "I wonder if there is a difference in temperature between soda in a can or in a bottle?" (and do they loose temperature at the same rate).
I thought I could tie this question in nicely with our unit on light we just started. We have been exploring properties of light (it contains energy) and what happens when it hits objects. Using information we have studied students would be introduced to the question and then they would have to make a hypothesis.
I thought it would be a nice easy classroom experiment. All you have to do is take a cold 12 oz bottle of diet coke and a cold 12 oz can of diet coke and then have students record the temperature of each every 5 minutes for about twenty minutes and discuss the results and what part light might have played in the experiment.
