The dependent variable is the outcome or measure of change, and the independent variable is the variable that is changed by the experimenter and tested. An educated guess of how the experiment will turn out, worded in terms of the independent and dependent variable. Complete list of materials used to conduct the experiment, including amounts. List of steps followed in conducting the experiment to test the hypothesis. The constant variables and control should be noted.
Constant variables are conditions of the experiment that are kept the same.
Control is a standard to test your experimental results against. Photographs, charts, graphs, data or drawings that support the information in the project should be displayed. It should include any discoveries that were not originally planned and a discussion of potential errors, plus a description of what one would do to extend, or improve on, this research project.
