There will be a 10 point deduction if this is not done. Each question is worth 5 pts. Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms require 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. 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? Explain why each was chosen.

What type of graph would be appropriate for this data set — a line graph or bar graph? 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. A study is being done to test the effects of soil nutrients on the size of daisy populations.

Planters with different concentrations of fertilizer are set up with 10 daisy seeds in each one. Over a period of three months, the daisies are given the same amount of water and sunlight.

The planters are equally maintained and cleaned throughout the experiment. The temperature of the room is kept constant.
