Cell Structure

Cell Structure

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles. Here we cover them all.

Structure of Atom

Structure of Atom

Atom consists of electrons, protons and neutrons. There is an interesting story on how electrons, protons and neutrons were discovered and how the structure of atom has come to be. It’s worth knowing about the fundamental particles of matter.

Atoms & Molecules


Yes, this is all about how atoms combine to form molecules. Combination of atoms to form molecules can be explained by various laws. We not only cover these Laws, but see how actually atoms combine to form molecule, symbols and formula of atoms and molecules and various ways of expressing their masses.

Is the Matter around us Pure

Matter is composed of Solids, Liquids and Gases.  For a better understanding of Matter, there is a need to differentiate it on the basis of composition.  On the basis of composition, matter can be classified as:

(i) Pure substances; and


States of Matter

Matter in our Surroundings covers topics like what is matter, characteristic properties of matter, States of Matter, Change of State of matter and Evaporation. We cover all these topics in depth. If you have any queries due leave them at the comments. We will positively answer it. Also sharing is caring. Share these notes with friends in facebook.

Class X: Electricity and Magnetism in ONE diagram

This simple diagram will help you to remember two chapter namely Electricity and Second Magnetism and its Properties in a snapshot.


The Physics paper for Class 12 this will have a total of 26 Questions having a total of 70 Marks broken into to 5 Sections.

The questions will be of 1 mark, 2 marks, 3 marks, 4 marks and 5 marks each. If you have handle the Section C having 12 questions of 3 marks each, then you will surely score upward of and easy 55 marks this year in the Board Exam.

Soaps & Detergents

To achieve effective cleaning, it is helpful to have a basic knowledge of soap and detergent chemistry.  Here we learn the composition of soaps and detergents and their cleaning action.

Carbon – An unique element

Carbon is the most versatile element known to man.  It is the source of Organic Compounds- believed can only be distilled for living things.  Man is a carbon-based animal and our world revolves around it.  Here’s a look at why carbon is so important to us.

Periodic Classification of Elements

The Periodic Table is a tabular arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations (electron shell model), and recurring chemical properties.

Chemical Bases

Bases are substances that, in aqueous solution, are slippery to the touch, taste bitter, change the colour of indicators (e.g., turn red litmus paper blue), react with acids to form salts and/or contain completely or partially displaceable OH− ions.


Acid is any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen and reacts with bases to form salts. They give H+ ions in aqueous solution.
