Record your hypothesis from Step 1 in the Procedure section here.
Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life.
The dissolved oxygen is measured in units of ppm parts per million. Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.
Post-Lab Questions What patterns do you observe based on the information in Table 4? Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. What would your experimental approach be to test this hypothesis?
What would be the independent and dependent variables? What would be your control? What type of graph would be appropriate for this data set?
Graph the data from Table 4: Fish Population found at the beginning of this exercise. Interpret the data from the graph made in Question 7.
Experimental Variables Determine the variables tested in the each of the following experiments. If applicable, determine and identify any positive or negative controls. Observations A study is being done to test the effects of habitat space on the size of fish populations.
Different sized aquariums are set up with six goldfish in each one. Over a period of six months, the fish are fed the same type and amount of food. The aquariums are equally maintained and cleaned throughout the experiment. The temperature of the water is kept constant. At the end of the experiment the number of surviving fish is surveyed.
To determine if the type of agar affects bacterial growth, a scientist cultures coli on four different types of agar. Five petri dishes are set up to collect results: One with nutrient agar and coli One with mannitol-salt agar and coli One with MacConkey agar and coli One with LB agar and coli One with nutrient agar but NO coli All of the petri dishes received the same volume of agar, and were the same shape and size.
