A syllabus for Science classes IX and X, focusing on core concepts and hands-on activities.

Thinking skills and knowledge processing.

Emotional and social development in learning.

Skill development in science through action.

Assessment for 20 marks in science, combining periodic tests and diverse methods.

Assessment tools for internal marks: best two out of three

Various assessment tools like tests, oral tests, quizzes etc. in addition to periodic test

The major topics covered in science curriculum: Food, Materials, Living things, How things work, Moving things etc.

Anything that has mass and takes up space.

Transformation of matter between solid, liquid, and gas phases.

Pure substance composed of only one type of atom.

Substance formed by bonding of two or more elements.

A cell lacking a nucleus and membrane-bound organelles.

The central part of a cell containing genetic material (DNA).

Specialized structure within a cell with a specific function.

The basic unit of an element.

Motion at a constant speed in a straight line, with equal distances covered in equal intervals of time.

Rate of change of velocity.

Three laws describing how forces affect motion: 1. Law of inertia, 2. Force = mass × acceleration, and 3. For every action, there's an equal and opposite reaction.

The tendency of an object to resist a change in its motion.

The product of mass and velocity of an object.

The force of attraction between any two objects with mass.

Transfer of energy by a force causing motion.

Plant tissues are classified into Meristematic and Permanent tissues, which have different functions.

Creating a mixture where one substance dissolves completely in another.

Creating a mixture where the particles of one substance are dispersed in another, but do not dissolve completely.

A mixture where the particles are intermediate in size; they don't dissolve completely, but remain dispersed.

Identifying whether a change in matter alters its composition (chemical) or merely its form (physical).

Finding the mass per unit volume of a substance, often using a spring balance and a measuring cylinder.

Temperature where ice transitions to liquid water.

Describing how sound waves bounce off a surface, obeying specific angles.

Measuring how fast a wave travels through a medium, using a stretched string or spring.

The equivalent resistance of resistors in series is the sum of their individual resistances.

The reciprocal of the equivalent resistance of resistors in parallel is the sum of the reciprocals of their individual resistances.

A temporary mount of a leaf peel prepared to show stomata, which are tiny pores on leaves responsible for gas exchange.

Respiration in living things releases carbon dioxide as a byproduct.

Ethanoic acid (acetic acid) has specific properties like a characteristic odor, solubility in water, an effect on litmus, and a reaction with sodium hydrogen carbonate.

A chemical equation with equal numbers of atoms of each element on both sides of the arrow.

Two or more reactants combine to form a single product.

A more reactive element displaces a less reactive element from a compound.

A scale used to measure the acidity or basicity of a solution, ranging from 0 to 14.

A reaction between an acid and a base that produces a salt and water.

A bond formed by the sharing of electrons between atoms.

A series of organic compounds with the same functional group and similar chemical properties.

A hydrocarbon containing only single bonds.
