1. experimental design: from the work you have done this semester, choose a topic and design an experiment you would be able to perform. in your design (1) state your hypothesis, (2) identify your dependent and (3) independent variables, (4) your control conditions and (5) describe your experimental procedure. you do not have to actually complete the experiment, just describe it with the application of the terms above.

Take two plants - ensure that both get the same amount of sunlight, but one will get little water and the other more water. Water would be the manipulated variable; the sun would be the independent variable and there is only one control. (1) make an observation; “water makes plants grow.” (2) draft the hypothesis “...if the .” (3) conduct the experiment; (4) gather the data; (5) Do the analysis to support or deny your hypothesis; and (6) repeat if necessary.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
