Class 8 Science
A year along NCERT's own chapter spine: the cell under a microscope and the microbes that raise dough and set curd, the two effects one electric current has, forces that touch and forces that reach, pressure and the winds and cyclones that pressure differences drive, what matter is made of and how elements, compounds and mixtures differ, solutions and density, and how mirrors and lenses bend a beam — closing on the food chains that tie an ecosystem together.

Electricity and its Effects
Forces and Pressure
- Forces: contact and non-contactLesson
Sort forces by whether they need the objects to touch, read a spring balance, and keep weight and mass apart.
- Pressure and how it is sharedLesson
Work out pressure from a force and an area, and explain why the same force presses harder when it is spread over less of a surface.
- Winds, storms and cyclonesLesson
Trace a wind back to a difference in air pressure, and follow the chain from a rising column of warm air to a thunderstorm and a cyclone.
The Nature of Matter
Solutions and Density
- Solutes, solvents and solutionsLesson
Name the solute and the solvent in a solution, tell a saturated solution from an unsaturated one, and say how temperature changes what will dissolve.
- Density, and how to measure itLesson
Calculate density from mass and volume, find the volume of an irregular solid by displacement, and say what heating does to density.
