EQ 4 By David Zhao The first step is to design a purpose for your experiment It should clearly state what you are trying to accomplish Next you have to make a scientific guess, a hypothesis, on what you think will happen. Then you should make your materials list. It should include everything you used in the experiment After your materials list you need to make a procedure It is a step-by-step list of what you do Be very detailed When you are in the mists of your experiment note down your observations and anything of interest. After the experiment has concluded write down the results too Analyze - your data by Making a graph of your data Looking for patterns in your data Making any needed calculations (percent change) Any new questions Sources of possible error Alternative explanations Tell if your hypothesis was correct Anything you found out Sum up your whole lab report
