Table 1 water quality vs fish population dissolved oxygen
If you choose this option.
Exercise 2: testable observations
Sometimes the DO is so low, there is hardly any aquatic life. When Sally eats healthy nutrients and exercises on a regular basis. Use the hypothesis to predict the characteristics that the sample should have. He has his mother listen to rock music, his sister listen to classical music, and his friend listen to rap music. Not testable because a hypothesis can non be formed. How will you analyze your data? The control could be the H2O temperature.
Graph the data from Table 4: Water Quality vs. Dependent and independent variables: the dependant variable is her blood force per unit area.
Then I would gradually begin adding fish daily, starting with one fish. Dissolved oxygen gets into the water by diffusion from the atmosphere, aeration of the water as it tumbles over falls and rapids, and as a waste product of photosynthesis.
If applicable, determine and identify any positive or negative controls. When a works is placed on a window sill. Large daily fluctuations in dissolved oxygen are characteristic of bodies of water with extensive plant growth.
Exercise 1 design an experiment
The control could be the H2O temperature. The most appropriate type of graph to utilize, which would best illustrate the data being compared in this example, would be a line graph. A line graph is most appropriate because it can best display the relationship between the variables. How will you present your data charts, graphs, types? When the concentration is higher than 12 ppm, the relationship is less clear. Over a period of six months, the fish are fed the same type and amount of food. For the past two days the clouds have come out at 3 pm and it has started raining at pm. Oxygen gas that is dissolved into water is dissolved oxygen, or DO. Dissolved oxygen gets into the water by diffusion from the atmosphere, aeration of the water as it tumbles over falls and rapids, and as a waste product of photosynthesis.
Measure the dissolved oxygen level in a fish tank at normal room conditions, and repeat this measurement every time you make an observation of the number of fish.
