Directions For Questions

In order to explore the effect of different environments on blood flow, a small fresh water fish is used. For the experiment, a fish with a wet cotton ball over its gills is placed in each petri dish for the diffusion of oxygen which keeps the fish alive. The thinnest part of the tail is then viewed under the objective lens of a light microscope to see the flow of blood in blood vessels. The number of red blood cells flowing through the vessel is counted at a 5-second interval. After monitoring the normal flow of blood for 30 seconds, the environment in the petri dish is altered in one of five different ways. Students observe and record the change in blood flow if any. After the experiment, each fish is returned to the fish tank.
Experiment 1: Nothing is added to this petri dish.
Experiment 2: Water at a temperature of $$5^0$$ is added
Experiment 3: Water at a temperature of $$30^0$$ C is added.
Experiment 4: Ethyl alcohol is added.
Experiment 5: Nicotine extracted from cigarette tobacco is added.
