At the Harbour School in Hong Kong, TED Senior Fellow Cesar Harada teaches citizen science and invention to the next generation of environmentalists. He's moved his classroom into an industrial mega-space where imaginative kids work with wood, metal, chemistry, biology, optics and, occasionally, power tools to create solutions to the threats facing the world's oceans. There, he instills a universal lesson that his own parents taught him at a young age: "You can make a mess, but you have to clean up after yourself."

How I teach kids to love science

Inventive students tackle marine plastic pollution, crafting a robot in a Hong Kong workshop to quantify oceanic plastic debris.

Empathy drives innovation as students ship a prototype sensor to Bangladesh, aiding local children in identifying water contaminants.

Empowering young minds, a Hong Kong classroom evolves into a lab crafting solutions for global oceanic issues using everyday items.
