NCERT Solution for Class 6 Science

Chapter 16 - Garbage In, Garbage Out

1. (a) Which kind of garbage is not converted into compost by redworms?

(b) Have you seen any other organism besides redworms in your pit? If yes, try to find out their names. Draw pictures of them.

Answer.

(a) Garbage containing polythene bags, plastics, metals and glass which do not rot cannot be converted into compost by red worms.

(b) Yes, I have seen some earthworms and small insects in the pit. There may be some microbes also in the pit which help in decaying of garbage.

2. Discuss:

(a) Is garbage disposal the responsibility only of the government?

(b) Is it possible to reduce problems relating to the disposal of garbage?

Answer.

(a) No, every citizen should be equally responsible along with the government for proper disposal of garbage. We should reduce activities that pollute the environment. We should not throw garbage on streets, roads or parks. It should be thrown at right places. We should reduce the use of polythene bags, plastics and other things which do not get degraded but pose serious problems in the environment. We should also reduce the production of waste.

(b) Yes, it is possible to reduce problems related to disposal of garbage by following the measures given below:

  • Reduce the production of waste.
  • Reuse the used things for various other purposes.
  • Avoid using plastic bags.
  • Reduce the use of paper.
  • Keep the recyclable waste in separate bins.

3. (a) What do you do with left over food at home?

(b) If you and your friends are given the choice of eating in a plastic plate or a banana leaf platter at a party, which one would you prefer and why?

Answer.

(a) Left over food is dumped into the compost pit to make manure which is then added into the soil to make it fertile.

(b) We would prefer to eat food in a banana leaf platter because it is harmless and can be converted into compost. On the other hand, using plastic plates to serve food is not good for health as plastic contains harmful chemicals. Plastic plates cannot be converted into compost andcause environmental pollution.

4. (a) Collect pieces of different kinds of paper. Find out which of these can be recycled.

(b) With the help of a lens look at the pieces of paper you collected for the above question. Do you see any difference in the material of a recycled paper and a new sheet of paper?

Answer.

(a) All types of paper can be recycled.

(b) Surface of the recycled paper appears a little rough whereas the surface e of new sheet of papers appears smooth.

5. (a) Collect different kinds of packaging material. What was the purpose for which each one was used? Discuss in groups.

(b) Give an example in which packaging could have been reduced?

(c) Write a story on how packaging increases the amount of garbage.

Answer.

(a) The different kinds of packaging materials include plastic bags, thermocole sheets, foam sheets, paper bags, etc. All these packaging materials are used to protect the household articles, food items or other goods when transported from one place to another.

(b) Packaging of food-items, gift packs, chocolates, toys, clothes, shoes, etc., can be reduced.

(c) Unnecessary packaging is a serious issue that increases the amount of garbage. When we open a package, we use the things packed inside it while the packaging material is of no use and we throw it. Sometimes, people throw the packaging material on streets and roads which becomes difficult to dispose off. This causes environmental pollution as well. Sometimes, these packaging materials go down the drains and block the flow of water. This causes the problems arising due to stagnant water. Thus, packaging definitely increases the amount of garbage can cause difficulty in its proper disposal.

6. Do you think that it is better to use compost instead of chemical fertilizers? Why?

Answer.

Yes, it is better to use compost instead of chemical fertilizers. Compost is made out of natural or organic things like plant and animal wastes which do not cause any pollution. Whereas the chemical fertilisers are prepared from harmful chemicals which cause soil and water pollution.
