Things you can pull, drag and break. Each simulation works on a phone and maps to a topic in the school science & maths curriculum.
Class 12 · Physics electric charges and fields Free
move a charge in and out of a closed surface and watch the flux, seeing that only the charge enclosed matters.
Class 8, 12 · Physics electric charge Free
charge the electroscope by touching it with a charged rod, and watch the two gold leaves repel and spread apart as like charges push each other away.
Class 12 · Physics electric charges and fields Freeplace charges on the corners, edges and centre of a regular polygon and see the net force on every charge build up as the vector sum of all the others.
Class 12 · Chemistry solutions Freedescribe a solution once and see its mass percent, mole fraction, molarity and molality side by side.
Class 12 · Chemistry solutions Freemix two volatile liquids and watch the partial and total pressures build the Raoult plot, with ideal and non-ideal deviations.
Class 12 · Chemistry solutions Freewatch solvent flow across a semipermeable membrane toward the concentrated side, raising the level until osmotic pressure stops it.
Class 12 · Maths relations and functions Free
toggle ordered pairs on and off and watch whether the relation is reflexive, symmetric, transitive, and so an equivalence relation.
Class 12 · Maths relations and functions Free
build a mapping between two sets and see whether it is a function, and if so whether it is one-one, onto, or bijective.
