             Atom        Atom is a Greek word which means indivisible   they believed that matter can be broken  down  into very  small indivisible particles . 1. In other words we can say atoms are fundamental building blocks of matters. 2.  Matter composed of three subatomic particles the proton ,the neutron and therefore the electrons.           1.  In other words we can say atoms are fundamental building blocks of matters. 2.   Matter composed of three subatomic particles the proton ,the neutron and therefore the electrons.            Atomic    theories.

MAGNETIC EFFECT OF CURRENT To understand Magnetic effect of current, first we should know  what is the Magnet? Magnet A Magnet is an object which attracts pieces of iron, steel, nickel and cobalt i.e. it applies force on these objects. It has various types. The most common are - Bar Magnet Horse shoe magnet The end of a freely suspended magnet always points towards north – south direction. The end which points towards north is the north pole of the magnet whereas the end which points towards south direction is the south pole of the magnet. If two magnets are placed together with similar poles towards each other, then they repel each other (tends to move away), whereas if two different poles are towards each other, then they attract (tends to move towards each other). Hence, like poles repel each other and unlike poles attract each other. Magnetic compass It is an instrument consisting of base and a needle. The needle has north and south tip whose north tip is painted red (generally...

 MATTER IN OUR SURROUNDINGS Matter: Anything that occupies space and has mass is called matter. It exists in the form of five basic elements, the Panch tatva – air, earth, fire , sky and water. For example: Chair, bed, river, mountain, dog, tree, building, etc. Characteristics of matter: Matter is made up of small particles called atoms. These particles are too small to be observed with naked eye. These particles are constantly moving constantly. These particles have spaces between them. Particles of matter attract each other because of the force of attraction. Diffusion: Particles of matter intermix on their own with each other. They do so by getting into the spaces between the particles. This intermixing of particles of two different types of matter on their own is called diffusion.  Applications of Diffusion: Dissolving a solid in a liquid: When a crystal of potassium permanganate is placed in a beaker of water, the water slowly turns purple on its own, even without stirrin...

Health  is defined as a state of complete physical, mental and social well-being. (i) The factors which affect human health are: (a) Genetic disorders (b) Infections (c) Lifestyle. (ii) Balanced diet, personal hygiene and regular exercise are very important to maintain good health. (Hi) Awareness about diseases and their effect on different body functions, vaccination against infectious diseases, proper disposal of wastes, control of vectors, maintenance of hygienic food and water resources are necessary for achieving good health. 2. Disease  is a state when functioning of one or more organs or systems of the body is adversely affected, characterised by various signs and symptoms. Diseases can be divided broadly into the following two categories depending on the modes of transmission I. Infectious diseases which easily transmit from one person to another, e.g. AIDS, common cold, etc. II. Non-infectious diseases which does not transmit from one person to another, e.g. cancer, d...
