Electricity and Circuits

Key notes for class VI Science Chapter-12 Electricity and Circuits it includes revision notes such as Bulb: Lights up when an electric current flows through it. An electric bulb has a filament that is connected to its  terminals. An electric bulb glows when electric current passes through it. The filament of an electric bulb is made of a tiny , coiled tungsten wire.

Fun With Magnets

Key notes for class VI Science Chapter-13 Fun With Magnets it includes revision notes such as Single Touch Method:  When a magnet is used to rub an iron object along it's length, the starting from one end to another end like combing one's hair, the iron object gets magnetised.  Double Touch Method: When an iron bar ( object ) is rubbed by two powerfull bar magnets of equal strength with their opposite poles at the centre, in opposite direction , the bar or the object becomes a magnet.

Water

Key notes for class VI Science Chapter-14 Water it includes revision notes such as The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Air Around Us
