Zebrafish lab abstract

This experiment was conducted in order to observe the effects of sex-specific socialization on zebrafish metabolic rates. We wanted to observe whether zebrafish metabolisms would change in accordance with the gender of fish with which they shared an environment. We hypothesized that more energy is consumed during opposite-sex socialization because sexual arousal causes the fish to exert an excess amount of energy. We therefore predicted that if we put a male and female fish in an environment together we would find that the two would have a higher metabolic rate than a hypothetical sum of the metabolic rates of those two fish when in same-sex environments. However, our data did not end up being consistent with this prediction because of cofounding variables. Our trials were not accurate representations of sex-specific socialization because of overuse and exhaustion of the fish, and the time of day at which the trials were conducted. It would be important to repeat the experiment with greater recovery periods in between trials, and in the early day, during the period of morning at which zebrafish mate naturally. This would allow a more accurate representation of opposite-gender socialization, and therefore a conclusive analysis of the effect on the fish’s’ metabolic rates.  



You can change "cofounding" to confounding.

Parahraph was very well written and was clear and kept me interested throughout, not much I'd change!
