Deer: Srong teeth, long ears, eyes on the sides of head. Mountains: Animals have thick skin or fur; mountain goat has strong hooves. Trees are cone shaped having sloping branches; leaves are needle like.
Key notes for class VI Science Chapter-10 Motion and Measurement Of Distances it includes revision notes such as In ancient times, people used the length of a foot, the width of a finger, the distance of a step as units of measurement. This caused confusion and a need to develop a uniform system of measurement.
Key notes for class VI Science Chapter-11 Shadows And Reflections it includes revision notes such as Due to larger(extended) light source: Two shadows are formed-a dark one in the centre and a light one on the outside. Dark shadow is called umbra and the faint or lighter shadow is called penumbra.
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.
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.
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.
Key notes for class VI Science Chapter-15 Air Around Us it includes revision notes such as Water Vapour: Formed due to evaporation of water. Amount of water vapour present in the air is called humidity. Varies from place to place and also in the same place during day and night. Carbon dioxide: Plants and animals consume oxygen and produce carbon dioxide during respiration. It is used by green plants for photosynthesis. It is released on burning.
