Science Project Report From a 7th Grader: Testing Laundry Detergents #MakerEducation
Real-world science experiment from a 7th grader — via Science Buddies
“I need a science project that has a real-world application,” said my 7th grade son. “Our teacher says we can’t just put Mentos in a bottle of soda.” The Are Enzymes in Laundry Detergents Effective Stain Removers? project immediately grabbed his attention because he knew it would pass muster with his teacher. After all, what is more real-world than laundry?
Scrubbing can help remove those stains physically, and enzymes in laundry detergents can help remove them chemically. Enzymes are proteins that help chemical reactions occur, and some laundry detergents use them to increase the chances that the detergent can break down stains in clothing.
