Life under water Abstract

In open waters fish benefit in many ways from schooling. They can protect themselves from predators, they assure the safety of others as they travel together, and find food together. This experiment is trying to further the knowledge of fish schooling by conducting many experiments. In this experiment 3 trails were experienced. The first trial was to tap the center of the fish tank for 10 seconds at the same rate. The second trial was tapping on the fish tank for 20 seconds at the same place and also the same rate. The third and final trial was to tap on the glass for 30 seconds at the same rate, same place and all with the same person, which in this case would be my fellow

In the experiment we have a time taker, tapper, and 3 observers. The tank should have a black line straight down the middle of it, however, if the 10 gallon tank does not already have a line down the central part of the tank, take a sharpie and draw one exactly down the middle. Once you acquire the tank make sure there are 8 fish in the tank, if not, position 8 fish in the tank. The first trial that was done required the tapper and the time taker with 3 observers. The tapping began for 10 seconds while the fish behavior was observed by the 3 of us observers. After the 10 seconds the results were verified and discussed among the observers. There was an elimination period for 1 minute, and trial 1 was repeated again for the second time making it trail 2 for 20 seconds. The results were documented once again and discussed. The second trail that was done required a little more focus to assure the tapping and placement was the same as the one before. After 20 seconds the results were recorded. There was a rest period for 1 minutes, and trial 2 was repeated making it trial 3 for 30 seconds. The results were
