Purpose
The class activity was to pick gray and white butterflies of the tables. However, some of the tables were gray and some were white and with the lights turned off the butterflies camouflaged. This experiment showed that when butterflies use their traits of camouflage they succeed. Some butterflies did not succeed if the white butterflies were on the white tables they camouflaged so they don’t get eaten but if they were on the gray table they did get eaten. It showed the contrast of the butterflies dyeing. More white butterflies died on the gray table and more gray butterflies died on the white table.

On the gray background, 58 gray and 50 white butterflies starving. In the second trial, on the white background 80 gray and 51 white butterflies starving. on the gray background 58 gray and 50 white butterflies starving. In the third trial, on the white background 75 gray and 43 white butterflies starving. on the gray background 32 gray and 37 white butterflies starving. On the white background, there way more gray deaths than white. On the gray background there was way more gray than white.
Conclusion
My hypothesis failed to be rejected. It has failed to reject that white are going to die less on the white background and gray is going to die less on the gray background due to my results. This happened because the white camouflaged with the white and the gray camouflaged with the gray and the opposite color was seen more and eaten. A limitation is that these trails are supposed to be done at least three times to get an accurate result. Therefore, you can fix this problem by doing it three more time. This models to real life with the peppered moths. Some moths are light some are dark, the trees used to be light so the dark moths would be eaten then they turn dark so now the light moths are getting eaten. The moths then evolved to becoming darker. ("Science Aid.” Evolution and Natural Selection. N.p., n.d. Web. 7 May 2012.)We learned from
