Goldfish Respiration Rate Lab

Goldfish Respiration Rate Lab

(Milan, Stefan, Rohan, Andreas)

Introduction:

In this lab, my group and I conducted some experiments with fish and their water environment, observing how this affected their respiration rate. The main change was in temperature (making the water cooler and warmer), but we also added Coke to see how this changed the respiration rate. The 5 temperature zones that were tested were coldest (5 - 100C), cold (10 - 140C), room temperature (15 - 200C), hot (21 - 250C), and hottest (26 - 300C). For each temperature zone, we observed how many breaths the fish made in 5 minutes, and recorded the data. The one Coke test we performed was adding 6ml of Diet Coke to a container of water at room temperature. The results from this experiment are separated from the results of changing the temperature, due to their difference.

Hypothesis:

As the temperature of the goldfish environment increases, so will the respiration rate of the goldfish.

Table of Results

BP5M = breaths per 5 minutes

Temp in C	Our Group BP5M	Group 2 BP5M	Group 3 BP5M	Group 4 BP5M	Average BP5M
26 - 300C	915	1280	780	780	939
21 - 250C	789	1260	700	700	862
15 - 200C	617	640	600	560	604
10 - 140C	460	340	250	480	383
5 - 100C	210	180	200	380	243

Graph of Data

Zone 0 =  coldest (5 - 100C), Zone 1 = cold (10 - 140C), Zone 2 = room temperature room temperature (15 - 200C), Zone 3 = hot (21 - 250C), Zone 4 = hottest (26 - 300C)

Single Coke Experiment

	6ml of Diet Coke
Room Temperature (15 - 200C)	BP5M = 490
