A YouTuber and former NASA engineer invested $60M on STEM curriculum — it’s completely free for teachers
A NASA engineer turned YouTube sensation with over 75 million subscribers, Mark Rober makes creative, silly science experiments for an audience of primarily young viewers. It’s part of his mission to “get kids stoked about science.”
While he dreams of being a middle school science teacher himself, in the meantime, Rober just invested $60 million on a STEM curriculum to make it easier for teachers to implement fun, engaging lessons in STEM, without spending their own money on materials.
He just announced the final product at TED2026: Class CrunchLabs, an online STEM curriculum program tailored to grades 3 through 8 that “exceeds” state science standards — and it’s completely free for teachers.
Why is this good news? As Rober said in his TED Talk, “The reason we’re doing this is because it breaks my heart when I see teachers who get paid salaries that as a society we should be ashamed of, spending their own money on resources that totally suck.”
A South African politician went snorkeling in a pothole to highlight her city’s infrastructure issues
Johannesburg mayoral candidate Helen Zille is a 75-year-old politician. And on March 28, she donned a wetsuit and snorkeling gear and leapt into a massive water-filled trench in the middle of a suburb.
The water has been collecting for three years due to a burst water pipe that remains broken, despite the city’s repeated attempts to fix it. It is a symptom of Johannesburg’s larger infrastructure issues, from recent electricity cuts to damaged roads.
Zille was in good spirits as she swam in the pothole to bring attention to the mismanaged policies, saying, “Here we are with a free and wonderful Saturday-afternoon snorkel.”
