Middle School Student Innovates with a Water Quality Testing Device
America’s Top Young Scientist
Discovery Education and 3M have awarded Gitanjali Rao the title of “America’s Top Young Scientist” with prize earnings of $25,000. Her device, which she named “Tethys,” clinched the top price in this year’s competition, which was the 10th anniversary of the Discovery Education 3M Young Scientist Challenge.
What is Tethys?
Contaminants in water pose a serious health risk for people all over the world. Lead poisoning can cause both short- and long-term health issues. Miss Rao’s invention is a portable, easy to use, and inexpensive water quality tester. It uses disposable water testing cartridges with chemically treated carbon nanotube arrays, an Arduino processor to process test results, and integrates with a smartphone via Bluetooth for quick display of results. Tethys boasts an innovative combination of several STEM components. You can see more about Gitanjali’s invention here.
