How to Write a Thesis Statement for a Science Report
A science report is generally completed after you do a scientific test or experiment of some sort. The thesis of the science report basically relates to what your hypothesis was before you began the experiment. The hypothesis is the question that you plan to answer or what you plan to prove. Before you start the experiment, you need to articulate your hypothesis. Once you complete the experiment, the hypothesis will be turned into the thesis.
Figure out the purpose of your science report. Most are based on an experiment or test that was conducted. In this case, take the purpose from your hypothesis. Your hypothesis basically states the overall purpose you had for the experiment, such as attempting to prove that training dogs using positive reinforcement is more effective than negative reinforcement.
Write down the conclusions of your scientific test or experiment. These conclusions will be used in your overall science report and they will help you write the thesis statement. Your conclusions from the above example might include that positive reinforcement is a more effective training method for dogs than negative reinforcement, that praise and attention alone worked more often than treats alone, but combining the two was most effective of all.
Turn your hypothesis and conclusions into the thesis statement for your science report. With the above example, the first draft of your thesis statement might be, “Positive reinforcement has been proven to be a more effective method of dog training than negative reinforcement.”
Add even more details to your thesis statement. The more details you can add, the stronger the statement will be. For example, you could add the types of training methods you were comparing, along with which types of reinforcement worked best, to get the following thesis statement: “While comparing positive reinforcement and negative reinforcement as methods of dog training, it was found that the most effective training method is using positive reinforcement with a combination of treats and praise from the dog’s owner.”
