Food: Where does it come from? (Part - 3)

 Food: Where does it come from? (Part - 2) 

Q.29. Name two ingredients in our food that are not obtained from plants or animals. Mention one source for each ingredient.

Ans. i) Salt: It is obtained from sea water or rocks.

        ii) Water: It is obtained from fresh water resource like rivers.

Q.30. Why should we avoid wastage of food?

Ans. Food is something which is a need of every organism for its survival. So, it is very important to value it/respect it and avoid wastage. On the other hand, enough food is not available for all. Also, there are many poor people around who can not afford meal for even one time in a day. So, as a good and educated citizen of the society, we should not waste the food and encourage others to avoid wasting food too. 

Q.31. Why do boiled seeds fail to sprout?

Ans. The boiled seeds failed to sprout because boiling kills the seed and damages certain chemicals or proteins that are required for germination.

Q.32. Corelate these food items with the region where they are popular:

  • Idli, Sambhar, Rasam - Tamil nadu (South India)
  • Dhokla, Debras - Gujarat
  • Daal, Baati, Choorma - Rajasthan
  • Sarson-da-saag, makki di roti - Punjab
  • Muro, Sondesh - West Bengal

 Q.33. People of a village eat lots of rice, prawns and crabs. Where do you think is the village located?

Ans. The village is located near the sea.

Q.34. What are milch animals?

Ans. The milk yielding animals such as cows, buffaloes and goats are called milch animals.

Q.35. How do herbivores differ from carnivores?

Ans. Herbivores eat only plant or plant products. Their teeth are designed to chew the plants and their stomach to digest them. Carnivores eat other animals. They have sharp teeth to tear the flesh of animals.

FRICTION Q.1. What is force? Write few of its characteristics. Ans.1.  A push or a pull on an object is called a force.                      Force is a vector quantity (having magnitude  as well as direction).           S.I. unit of Force is N (Newton).           Force can Change the State of Motion.                   Force can Change the Shape of an Object. s          Q.2. What is friction ?      Ans.2.  The force which opposes the motion of an object on the surface of another object is called force of friction. Force of friction is a contact force. The force of friction always opposes the applied force (direction of motion).

FRICTION Q.3.  Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it. Ans.3.                                 Q.4. What is the cause of friction? Ans.4.  Friction occurs due to the interlocking of irregularities between two surfaces in motion to each other. Every object has some sort of irregularities in its surface, so when two surfaces come in contact with each other and one object moves over the another, so their irregularities get interlocked and moving object starts losing its energy in breaking the interlocking and finally it comes to rest.                                             Q.5. What are the factors on which friction depends? Ans.5.  There are two factors affecting friction: 1.      Nature of the surfaces: Friction increases with roughness and decreases with smoothness of the surfaces. On rough surfaces, there are a larger number of irregularities than the s

PRACTICE WORKSHEET (CLASS - VIII) TOPIC – FORCE AND PRESSURE 1. When a force acts on a moving object, it can make the object a) move faster b) slow down c) stop d) all of these 2. Name the type of forces involved in the following :  a) A horse pulling a cart _________________________  b) A moving boat coming to rest when rowing is stopped ___________________ c) A coin falling to the ground on slipping from hand ______________________  d) A sticker attached to steel almirah without glue _________________________ 3. Two students fought over a lunch box, both started pulling it from opposite ends but the box didn't move from its place. What will you infer about the magnitude and direction of the forces? 4. An archer shoots an arrow in the air horizontally. However, after moving some distance, the arrow falls to the ground. Name the initial force that sets the arrow in motion. Explain why the arrow ultimately falls down. Assertion / Reason :  For question numbers 5, two sta
