(a) Water is an elixir of life, a very important natural resource. Your Science teacher wants you to prepare a plan for a formative assessment activity, "How to save water, the vital natural resource." Write any two ways that you will suggest to bring awareness in your neighbourhood, on 'how to save water'.
(b) Name and explain any one way by which the underground water table does not go down further.

Explanation

(a) Ways to bring about awareness on 'how to save' water:
(i) We can conduct door to door campaign to make people aware about the acute shortage/scarcity of water during summer.
(ii) We can educate people on ways to save water, for example, close taps properly, use buckets of water to bathe instead of showers etc.
(ii) I can also suggest them how to store rainwater in the small park of our locality, so that it can be used hot summer days, when availability of water is very less.
(b) We can also prevent the level of underground water table to not go down further by harvesting the rainwater in the underground tanks in parks and cropfields.
