SHS Student Critical of Fish Education

I am a senior at Superior Senior High School. March 27 this year is the day where underclassmen share their science projects to upperclassmen to grade. This fair is a great tool for students to learn about science and try their own experiments that they are interested in. For an idea to be approved, it must go through the student’s teacher before worked on.

In the 10th grade, biology is a required class, and I will be talking about what I saw from the biology students. I will give no names because this is not to attack students, I am writing this to show poor education and learning on behalf of the teachers.

The first project I want to talk about is one where the students wanted to test if you could train a goldfish. Though already proven, this could be a fun experiment for students to learn about fish and their learning.

Firstly, the way to train the fish was using a bell. The sound waves from the bell cannot be translated into the water unless it was in the water. The teacher should of picked up on that first; a visual cue is much better for aquatic species.

Secondly, the students doing the experiment kept the goldfish inside of a small fish bowl at room temperature presumably with no filtration though I have no proof of that. They recorded the temperature at 54 degrees Fahrenheit, which is what a goldfish should be kept at during the winter; the problems come with the size and filtration.

I have no idea what type of goldfish it was; they kept absolutely no record of fish (all the details of the “tank” is from their words). They said they got it from Walmart, though, and judging from that I will give them the benefit of the doubt and say they got the smallest type of goldfish: the common. In general, a common goldfish should be given at least 30 gallons of water with high amounts of filtration just for a single fish at the minimum.

I will assume that the bowl they used was 2 gallons because it is a common one I see at Walmart; this “tank” will most likely have no water movement.

Water movement is detrimental to proper gas exchange which oxygenates the water. Goldfish are not labyrinth fish (which are fish that are able to get oxygen from…
