Start here: Investigate a charged beam →Investigate a charged beam
NCERT chapter connectionCompare an electron beam with a positive-ion beam between oppositely charged plates. Switch the upper plate’s polarity and observe the deflection. This is a qualitative charge–force model inspired by discharge-tube experiments, not a reconstruction or a calibrated trajectory.
Design a particle filter
NCERT chapter connectionChoose an ideal pore opening and suspended particle size. Particles smaller than the opening pass through; larger ones are retained. Actual filters have varied pores. Ordinary filtration does not remove dissolved salt from water.
Atomic structure
NCERT chapter connectionChoose an element and change its neutron count to explore isotopes. This simplified shell diagram shows neutral atoms of the first ten elements. Electrons are shown schematically, not on physical orbits.
Mass and moles
Suggested-level explorationThe mole connects a sample’s mass with its molar mass. Change the mass and select a molar mass to find the amount of substance.
Dilution
Suggested-level explorationAdd solvent to a fixed amount of dissolved solute. Choose the initial concentration for an initial volume of 100 mL; explore the final concentration after dilution.
Boyle’s law
Suggested-level explorationFor a fixed amount of ideal gas at constant temperature, pressure and volume are inversely related. Start with a volume of 1 L at the selected reference pressure.
Periodic table
Shared referenceSelect elements, compare groups and periods, then test your understanding in the element quest.
