“How Kids Change the World,” Episode 2 – How STEM Passion Today Creates Hope for Tomorrow


In 2017, Gitanjali Rao, a then-11-year-old scientist in Lone Tree, Colorado, invented a device to detect lead in tap water. Her invention, named “Tethys,” earned her the top prize in the 2017 Young Scientist Challenge and a grant from 3M.

Since then, she’s come up with even more brilliant ideas to solve problems and make the world a better place.

All across the globe, kids are embracing their role as future leaders and making a difference in their communities. NTC is highlighting the inspiring work they’re doing in a video series called “How Kids Change the World.”
