Answer:
a. Independent Variable: different sized aquariums
b. Dependent Variable: number of surviving fish
c. Controlled Variables/Constants: amount and type of food, aquarium maintenance and water temperature
d. Experimental Controls/Control Groups: none
Explanation:
In an experiment, the dependent variable is the condition that is being measured or tested in the experimental procedure, while the independent variable isn't changed and serves to measure the outcome of the dependent variable. Moreover, the constant variables are those conditions that stay the same in the experiment. As observed in the case above described, an experiment usually has multiple constant variables. Finally, a control group is composed of individuals/research subjects who do not receive the experimental treatment, and therefore they can be used to compare the outcomes observed in the experimental groups.
- 97% of all the water on the earth is salt water, which is not suitable for drinking.
- Only 3% of all the water is fresh water, and only 1% is available for drinking.
- 2% of the available freshwater sources is locked in ice caps and glaciers.
With growing population rates and such a small percentage of all the water on earth, it only makes sense that we must preserve and conserve this precious resource.
