(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.

(a) Two Ways to Bring Awareness in the Neighbourhood

1. Street Plays and Community Workshops (Nukkad Nataks): Organizing interactive street plays in local parks or community centers to demonstrate simple, daily water-saving habits (e.g., closing the tap while brushing, using a bucket instead of a hose to wash cars, and reusing kitchen wastewater for watering plants).
2. Door-to-Door Campaigns and Pamphlet Distribution: Distributing informative pamphlets that highlight the local water crisis, provide a checklist of water-saving tips, and encourage residents to install aerators on taps to reduce water flow.

(b) Method to Prevent the Underground Water Table from Depleting

• Name of the Method: Rainwater Harvesting (or Rooftop Rainwater Harvesting)
• Explanation:

Rainwater harvesting is a sustainable technique used to collect, filter, and store rainwater for future use or to recharge groundwater aquifers. In urban areas, rainwater falling on rooftops is redirected through PVC pipes into a filtration tank (containing sand, gravel, and charcoal). From the filtration tank, the clean water is directed into a recharge pit, borewell, or dug well. This allows the water to percolate deep into the soil layers, directly replenishing the underground aquifers and preventing the water table from falling further.
