One of the things that I love about the NGSS is that students are given the task of designing their own experiments. This worksheet is the first step in the process of teaching them how to design their own experiment. This worksheet focuses on explicitly teaching students about independent variables, dependent variables and experimental controls.

Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation 𝘥 = 65𝘵 to represent the relationship between distance and time.
