Why such a Controversy?

To accurately test the expansion of water can be quite difficult without the proper equipment and measuring tools: finding glasses that were the same circumference from top to bottom, what to measure with, to measure from inside or outside, etc. The results which Brandi described were defiantly interesting, though it would be hard to find some consistency: some students did their experiments in the freezer while others did theirs outside, size of containers, amount of salt, type of salt (sea salt, table salt), time measured. According to research, another student found that expansion is by 9%. Over the greenhouse controversy I do believe something is happening to our earth and we need to do what we can to prevent it, but I don’t know what or when something will happen.

I believe that there is such a controversy over the greenhouse effect because no one can test it accurately on a smaller scale to determine what will happen. Obviously one could not test it on the entire earth but to test it on a smaller scale would require all the same conditions: same weather patterns, chemical make-ups of each body of water and each land mass. Each tree, animal, person, machine, etc. each play apart in the world’s environment and it would be impossible to exactly recreate this on a smaller scale for proper testing. This is why I believe there is such a controversy…there just isn’t enough proven data to know just what will happen on such a large scale.
