Title: Laundry Detergent Test

Purpose: To find out which of these four laundry detergents work better: Woolite, Tide, No name, and Sunlight

Hypothesis: Which of these detergents will work the best: Woolite, Tide, No name, Sunlight, or water? Is Woolite worth the extra 5$ price compared to the rest of the detergents?

Prediction: The WooLite will work the best. The Woolite will work the best because it is the most chemically concentrated, the most expensive, and the highest quality. Woolite is worth the extra
money if you really want a cleaner and better wash.

Materials: Tide, Sunlight, No Name, and WooLite laundry detergent, 4 pieces of equal sized white cloth, a timer, 5 beakers, grape juice

Procedure:

Take a piece of white cloth and stain it with grape juice
Cut the cloth into 5 pieces
Put 5 drops of detergent on each piece
Submerge each piece in a separate beaker of 100 mL of cold water each filled with a different detergent
Move and swish each piece around for 1 minute

Take out of cloth and hang to dry over night

Observations:

– The water with the tide and cloth in it was the most cloudy after 1 minute and the plain water with no detergent was the least cloudy

The WooLite water was the most pink after stirred (pink was the colour of the grape juice stain)

-No name had the most bubbles while being stirred

-Sunlight and No name when immediately taken out of the water had blue stains from the detergent, but only the no name dried with the stain (see picture below)

– Tide and Woolite got the pen lines off the edges the rest didn’t

The pen lines smudged and smeared from the sunlight

All of the detergents including the water completely cleaned and got rid of the grape juice, leading us to believe that grape juice wasn’t a strong enough stain

– To cut the cloth pieces evenly we outlined the borders with pen, which was on the edges of each piece we cut. If not for the pen, all of the detergents would have worked the same. Luckily we were able to determine the winner by examining which one of the cloths had all of the detergent and all of the pens lines cleaned off.
Results:

After the fair test, the cloth from the tide detergent came out the whitest. The grape juice stain and the pen lines on the edges almost all completely came out. The Woolite detergent was a close second, but it still left a large pen smudge in one of the corners. All of the rest of the detergents including Sunlight, water, and No Name all got the grape juice out but still had pen lines on most of the edges.

Conclusion:

In conclusion the Tide worked the best and the cloth cleaned by it came out the whitest. Woolite is not worth the extra 5$ price, and you should save your money and buy tide because it works better anyway

IQ: The next experiment to compare the detergents would be to see how the skin reacts to each one. It would be hard to do a fair test for this because everyones skin is very different, but you could test it on your own skin to see what your personal preference is.
