Data Analyisis of the Green Roof: We have 3 roofs that we did our tests on. We have the green roof, the dirt roof, and a tin roof. We conducted 3 tests on each house. We put ice on the houses and collectd the water. Then we blew wind at it. Finally we warmed the houses to 85 degrees and put it out in the cold to test the tempature every 5 minutes. The green roof collected and used the water that we put on it. Only alittle of that water came out. In the wind test it lost only a tiny bit bit of dirt and the plants still remained. Over 10 minutes in the tempurature test it lost 5 degrees per minute. The dirt roof collected all the water. In the wind test it lost a lot of dirt. In the temperature test it proved that the dirt didn't help that much and lost about 7 degrees per minute. Finally the tin roof did not collect any water. It stood up to wind very well and only the coner wrinkled up alittle bit. It lost about 6 degrees per minute. This shows that the green roof worked really well. It lost the least amount of water, it collected and ussed most of the water and stood up pretty well up to wind and so did the tin roof.

Segio and I have the materials and will start building the buildings on friday. We have finished one of the three houses. The house that we made has no dirt or plants on it. It is simply representing the normal roof with three layers of tin foil on the top. We will complete the other two houses on friday through Saturday. If we are done on Saturday we will start the experiment on that day, if not then we will start it on Sunday. The second house we are going to make will have dirt and plants that are yet to be decided (sedum is out of season). For the third house we will just have dirt on the roof so we know if the dirt is helping much.
