Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.

Make works of art using a vintage yet effective etching strategy. The surface of a semiconductor chip has specific patterns formed through a process called etching. Through a lab investigation, young scholars recreate that process...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second lesson of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...
