Each scenario (station) should have a dedicated table row, or illustration, to log your data into. This illustration is an essential part of the evaluation. It must be understandable by a reader without your presence or verbal explanation required. Your documentation must stand alone and be sufficient for your experiment to be repeatable by others.
After recording your data move the fulcrum to the next position, (It is suggested you move your fulcrum at 1 inch even increments for ease of analysis and later calculations) repeat the washer activity and record your findings. You should have a total of 10 stations recorded before your data is complete. At this point you and your partner(s) should examine the data collectively to discuss patterns you may realize.
View the above picture as a suggested arrangement for organizing the documentation of your experimentation.
