What Is a Good Science Project That Involves Laundry Detergent?

A good science project involving laundry detergent would be to conduct an experiment to determine which laundry detergent is most effective at removing stains. The researcher can apply different types of detergents to identical stains on identical materials and compare the results to determine the most effective detergent.

This experiment could be used to compare homemade detergent to commercial detergent, to compare detergents that are plant-based to those that are petrochemical-based, or to compare detergents with enzymes to those without enzymes, according to About.com. Once the person conducting the experiment has decided which comparison to focus on, he can conduct background research and compose a hypothesis.
