Divide your class into a group of five students each. Ask them to collect data from various households through interview-cum-discussion to discuss and suggest ways for saving domestic fuels and electricity. The information may be collected as:

• types and kind of fuel used per month in the family.
• amount of electricity used per month or the fuel used on generator or any other resource used for lighting.
• amount of fuel used per month in vehicles.
• measures taken for saving electricity and domestic fuel.

Make a chart based on the natural water resources in your village or city. You can take the help of your parents or grandparents at the time of collecting information. Your chart may be based on the following:

What is depletion of resources?

How technological inputs and industrial development leads to the depletion of resources?

How population growth is causing depletion of resources?

Describe the relationship between soil erosion caused by overgrasing and agricultural productivity.

A village depends entirely on a single river for its water needs. Due to upstream industrial activities and overuse, the river’s water low has significantly decreased, leading to a water crisis. Identify the main causes of water scarcity in this village.
