Quick play labs for school students

Short, hands-on science and maths activities. Each one has four "Try this" goals to tick off, words to know and an activity to try at home. No sign-up needed.

For parents and teachers: every lab matches an NCERT topic. When a learner finishes, the full labs on the Class 6–8 and Class 9–10 pages go deeper and have practice questions.

Class 6–8 25 labs

Physics
