Some TED bts. It was an incredible experience to finally tell the world what we've been secretly working on for three years. Class CrunchLabs is a full science curriculum for third to eighth grade that hides the vegetables and makes science fun. It will cost $60M to make, and it will be free forever to all teachers because they deserve that and so much more. Please share the news with any teacher you know!

Not only did @markrober bring a little chaos to the TED stage… he officially announced the launch of Class CrunchLabs. We’re creating the world’s best science curriculum and giving it to teachers and the world completely free. 100% free. Forever. Videos. Assessments. Hands-on challenges that make a BIG impact on kids - not on teachers' wallets. Find the first 3 units at classcrunchlabs.org Tag a teacher you love and let them know reinforcements are here!
