Abstract

This experiment is on the effect of different levels of oxygen on the growth rate and size of Bullfrog tadpoles. This research could be used to help create solutions for creating a larger food supply by trying to replicate this on an animal we use for food, lowering the price of that food and making it easier for less fortunate people to get a source of food. I hypothesize that the shrimp exposed to the most oxygen will grow to the largest size and have the highest growth rate. My null hypothesis is that the varying levels of oxygen will have no effect on overall growth and growth. My alternate hypothesis is that the shrimp exposed to no extra oxygen will grow to larger sizes than the ones exposed to extra oxygen. This will be accomplished by starting with 33 tadpoles, which have been in water with normal oxygen levels. They will be raised in these conditions and will be measured every other day for 11 days. The independent variable is the oxygen levels, which will be changed by spraying boost 95% oxygen into the water. The dependant variable is the size of the tadpoles which I hypothesize will be dependant on the amount of oxygen in the water. The data was analyzed and it was discovered that an increase in oxygen caused the tadpoles to become smaller and less healthy than those raised in water with regular oxygenation.
