14. Changes in the surroundings and their effect 

Background

Everyday we hear about the changes taking place in our environment. This may not be very obvious to us if we compare two consecutive years since in most cases environmental changes take place slowly. But we can understand it better by comparing the environment a few decades ago and with the present scenario.

Methodology

1. Observe your surroundings and notice if any change is taking place or has taken place during the last five years or so. For example, construction of houses, buildings, construction, widening of roads, filling of ponds, reduction in agricultural land, felling/plantation of trees, electrification, irrigation facilities, etc.

2. Collect information from your parents, grandparents and elders in the locality to find out the changes which have taken place over the years.

3. Also find out how these changes have affected availability of water, playgrounds, electricity, fuel and fodder, hygiene and sanitation, transport and communication, crop production (including fruits andvegetables) or any other.

4. Collect articles, photographs, news items from local newspapers on changes in the locality and the life of the people.

Conclusion

Prepare a report on the basis of your findings.

Follow-up

1. Prepare charts of the gradual changes taking place in your surroundings and display them in your school bulletin board.

2. Find out the effects of developmental activities taking place in your locality on the environment.
