Fortune Telling Fish Lab
Evidence of Work
My group and I were assigned the task to make and test a hypothesis about why Fortune Telling Fish reacts the way it does when it is put on a human hand. I worked on this lab with Frankie and Kimberly. We hypothesized that the reason the fortune telling fish would roll because of moisture level. We then tested multiple trials, and concluded that moisture is a big factor to why the Fortune Telling Fish reacts the way it does.

Problem/ Question-
Why does the Fortune telling Fish react the way it does?
Observation-
We saw that when the Fortune Telling Fish was places on classmates hand who had sweatier hands than mine, it curled up and supposedly "told them their emotion". But when the fish was placed on my hand (me having very dry hands) it would not curl.
Hypothesis-
My group hypothesized that the reason the fortune telling fish would curl when placed on a human hand was be caused by the moisture level the person's hand that it was being placed on.
Experimentation-
We tested our hypothesis by conducting three experiments. We set a Fortune Telling Fish on 4 different paper towels with various moisture levels. One paper towel had one drop of water, another had two the drops, the third had three drops, and the fourth has no water on it. We then observed the 4 fish and saw how it reacted to the various moisture levels.
Collect Data-
Analyze Data-
Based on the data we collected we concluded the amount of moisture exposed to the fish determined the degree in which the fish curled. There we also things that went wrong. One thing that went wrong during our experiments, was putting too much water on the fortune fish. We found out that if you expose the fish to too much water it will tightly curl on the ends, then seconds after it will crumble up and get waterlogged.
Conclusion-
The more water the fish is exposed to the more it curls up. When exposed to more water the fish curls up more, rather than being exposed to no/less water. This happened because there must be some type of chemical on the surface of the fish, making it react to the moisture exposed to it.
