  • Living things are organisms that have life e.g. plants, animals, insects, birds, human beings, microorganisms etc.
  • Non- living things are things that don’t have life e.g. pen, bottle, door, computer, mobile etc.
  • Differences between living and non-living things.
Living things Non-Living things
(a) Living organisms need food, air and water 1. Nom-living things do not need food, air and water.

  • All the planets move around the Sun in fixed paths called orbits.
  • Mercury, Venus, Earth and Mars are called inner planets because they are close to the Sun. They are made of hard rock.
  • Jupiter, Saturn, Uranus and Neptune are called outer planets as they are far away from the Sun. They are also known as gas giants.
  • The movement of the earth about its axis is called rotation. It takes 24 hrs. to rotate once.
  • The movement of the earth around the Sun in an orbit is called revolution. It takes about 365 days for the earth to complete one revolution around the Sun.
  • Revolution of the earth causes changes in seasons.
  • Moon is the earth’s natural satellite.
  • Changes in the shape of the moon are called phases of the moon such as new moon, crescent moon, half moon, gibbous moon.
  • The moon is made up of rocks and dust. There is no air on the moon. So, there is no life on the moon.
  • Neil Armstrong was the first man to land on the moon in 1969.

  • Atmosphere means the sphere of air surrounding the earth. Mainly, there are four sub- systems called spheres, they are land (lithosphere), water (hydrosphere), living things (biosphere) and air (atmosphere).
  • The atmosphere consists of four unique layers:
The troposphere       (0-8 miles) The stratosphere       (8-30 miles) The mesosphere       (30-50 miles)                                   The thermosphere    (50-120 miles)                                 
  • Atmosphere protects the life on the earth. Atmosphere has gases like nitrogen hydrogen, carbon dioxide, argon, helium and some more gases. It has 78% nitrogen, 21% oxygen and 1% other gases.

  • Air is present in the environment. Air is a mixture of different gases like nitrogen, oxygen, carbon dioxide etc.
  • Air contains 78% nitrogen, 21% oxygen and remaining 1% other gases.
  • Living things need air to breathe. We must breathe in fresh and clean air.
  • Wind is the movement of air, there are mainly two types of wind - global wind and local wind.
  • Global winds are the dominant prevailing wind patterns that blow in a fairly, constant, steady direction across our earth.
  • Local winds are small scale wind of local origin caused by temperature difference. They can move up, down and horizontal. E.g. wind of mountain areas.

  • All living things need water to live. Life is impossible without water.
  • Water, ice and water vapors are three states of water. All the three forms are inter convertible.
  • Freezing point of water is \[0{}^\circ C\]and boiling point of water is\[100{}^\circ C\].
  • We get water from rain. These are the sources of surface water. The main sources of' water are rivers, lakes, ponds and reservoirs.
  • Some rainwater seeps into the ground called ground water.
  • Water cycle \[\to \] As the Sun heats up the water in river, lakes, ponds and sea, the water vapor rises. Then, it cools and forms small water droplets. Cloud are formed which give rain, which goes back to seas and rivers. This is called water cycle.
  • Evaporation \[\to \] the change of state from a liquid to a gas is called evaporation.
  • Rate of evaporation depends upon temperature, wind, area of exposed surface and humidity.
  • Condensation \[\to \] the change of state of steam from a gas to a liquid is called condensation.
  • Water is very precious. So we should conserve it. Reducing, revising and recycling are the ways of conserving water.
  • There are mainly four seasons in a year - summer, winter, autumn and spring.
