In our project we are testing how different temperatures affect a goldfish respiratory system. We will test four fish, one at a time. Both chambers with different temperatures to test whether or not different temperatures have an affect on the goldfish respiratory system. The fish use their gills to extract oxygen from the water. What we are trying to figure out is if different temperatures will affect the rate at which they consume oxygen. We will use an oxygen probe to measure how much oxygen is left in the chamber, which will allow us to see which temperature effected the crabs respiratory system. After 30 minutes we'll pull out the fish and record our data.
