==== **__Hypothesis __** - proposed explanation made on the basis of limited evidence as a starting point for further investigation. ====

====**__Independent variable __** -is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable ====

====**__ Dependent variable - __** is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable. ====

====**__Control groups __** - non-experimental groups -- that is, they have not been subjected to the experimental treatment. Used for comparison. ====
