Do you have some children at home in need of a science fair project? Here’s one that won’t cost a lot of money but will result in some excellent information about the best laundry detergent out there.
One of the most universal tasks on the planet is washing clothing. This is an activity that has been done for millennium as a normal part of life. If you are trying to come up with an idea for a science fair project then consider developing a project that tries to answer the question, “which laundry soap gets out stains the best?” or “Which environmentally safe soap works is the most effective?”
Research Laundry Soap
The first step is to learn more about what laundry soap is made up of and how it works. You will want to look at each ingredient in common laundry soap to determine what components are responsible for getting clothes clean. This information, which can be found in encyclopedias, online and in chemistry reference books, will help you to develop a prediction of which laundry soap will get stains out the best.
It is also a good idea to research the characteristics of various types of stains. For example, you can examine why oil based stains are more difficult to get out than water-based stains. The more you know about your variables, the better you will be at making a prediction and designing an experiment you’re your project.
Develop a Hypothesis
The next step is to make a prediction. This prediction will be your hypothesis. For example, you may predict that laundry soaps that contain bleach will get stains out best.
Develop an Experiment
Step three is to develop an experiment. This experiment will need to test your hypothesis. The experiment will need to isolate one variable at a time. For example, if your hypothesis is that laundry soap that contains bleach will be best for getting out stains then you will need to set up your experiments so that each experiment will compare bleach based laundry soaps against laundry soaps that contain other stain fighters.
The data collection process will be based on observations made by you. You will need a microscope and a white scale. After each experiment you will use a microscope to determine how much stain residue remains and how white the cloth is after being washed. You will need to rate the stain remaining properties of each laundry soap.
Analyzing Your Data
The next step is to analyze your data. For this you will need to use statistics to determine if there is a stronger relationship between bleach based laundry soaps and stain removal than there is between other types of laundry soap and stain removal.
Developing stain removal science fair experiments can be a lot of fun. It may also lead to the development of a brand new “green” stain fighting laundry soap compound.
