Chemical vs. Botanical Hand Lotion Science Fair Projects

Setting up chemical vs. botanical hand lotion science fair projects is pretty easy to do. The first step is to find a focus for your project. For example, you can look at the ingredients used in both chemical and botanical hand lotions, or you can compare the results obtained by chemical and botanical hand lotions. In this article the experiment is going to compare the results obtained by chemical and botanical hand lotions.

After you have your focus your next step is to develop a hypothesis for your chemical vs. botanical hand lotion science fair projects. For this experiment the hypothesis will be that botanical hand lotions heal dry hands better than chemical hand lotions. In addition to a hypothesis, high school students will also be asked to identify their null hypothesis. The null hypothesis is basically just the opposite of your hypothesis, and for this experiment the null hypothesis is that botanical hand lotions will not heal dry hands better than chemical hand lotions.

Now you are ready to develop your biochemistry science fair projects experiments. For this experiment two different lotions will be used. One will be an organic botanical hand lotion and the other will be a generic chemical based hand lotion. There will be five test subjects, each of which will have dry skin, and one control subject with dry skin. Each test subject will be asked to apply botanical hand lotion to their left hand and chemical hand lotion to their right hand for the duration of one week. They will be given instructions for how many times they can get their hands wet in a day, how much lotion to use and how much exposure their hands can have in a typical day.

Step four is to collect your data for your chemical vs. botanical hand lotion science fair projects. To start with you will want to collect your initial observations about each test subject. You will want to take a digital photograph of the left and right hands of each test subject. Your control subject will also need to be photographed, however, they will not be applying any lotion to their hands, but they will be required to follow the same instructions as the test subjects. At the end of the week collect "after" photographs and make your observations.

Step five is to analyze your data. You will need to determine which product seemed to work better, the chemical hand lotion or the botanical hand lotion. Explain your results. After you have drawn your initial conclusions you will need to think critically about your results. Think about possible confounds, which are basically outside factors that weren't considered when designing your experiment that could have influenced your results. In this experiment one possible confound is the extra use one hand gets over the other due to right handedness or left handedness. Discuss how this could have possibly influenced the final results of your experiment.

The final step of your east fast science fair projects on hand lotion is to present your experiment in a visual format. Usually you will be required to develop a visual display board. This board will need to include your before and after photographs, an explanation of your experiment, the steps you took and the data you collected. You will also need to provide viewers with a bulleted list of your findings, conclusions and recommendations for further research on your topic. As you work on your display board, keep in mind that it will need to be easy to read from a distance and it will need to be visually interesting.
