When conducting an experiment, it is important to have a hypothesis in mind and know what variables you will be looking at to help you in your testing. Ordinarily a scientist will perform a sort of experimental design before beginning any lab work. To gain some experience with this type of work, complete and attach an Experimental Design Worksheet for this experiment. Please use the worksheet provided under this experiment on Canvas. An example worksheet can be found under the...
