IV. Experiment

• Experimental design: Record all details related to your experimental design. For each research question, there should be 1 hypothesis. For each hypothesis, there should be 1 experiment. How many levels are there for the independent variable (usually 6 for a significant evaluation of hypothesis)? How do you change the independent variable? How do you measure the dependent variable? Did you carry out a trial experiment? Did you repeat your experiment and take the average to improve accuracy? There are some designs that are unique to your experiment.

• Experimental setup: Record all details related to your setup. Include a diagram and any changes to diagram subsequently if your setup should change during the course of the experiment.

• Experimental procedure. Record all details related to your procedure. Document your steps, trials, and observations to be made. Make sure that your experimental design steps (e.g. levels of independent variable, repeat experiment) are incorporated to the procedure section. You must also list the procedures on how would you analyse the data, including a table that you will use to tabulate your data, a graph if your hypothesis is correct, and how you will arrive at a statement of how your hypothesis is verified or not.

• Be sure and clearly note any modifications you make and any problems you encounter, including any mistakes. Even if it seems trivial or inconsequential, you should write it down in this paragraph.

Before the experiment, we came uo with an idea of how our setup would look like.
