Significant figures and error propagation
Take repeated noisy measurements of length, mass and time, find mean, absolute/relative error, and see how errors combine in sums, products and powers (density, g from a pendulum).

What you do in the lab
Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.
