The Air Quality Index (AQI) in Delhi, which measures how much tiny particles are in the air, has been way above the safe limit for the past two weeks. Pollution in the city gets worse in the winter because of things like burning crops and slow winds. The government in Delhi has tried to fix the problem by doing things like letting kids out of school early and stopping construction. Now they're asking the Supreme Court for permission to use cloud seeding.
Cloud seeding is when you spray tiny particles of salt onto clouds to make it rain. But for this to work, the weather conditions have to be just right, like having enough moisture and wind. The salt particles have to be sprayed into clouds that are growing upwards. Cloud seeding has been used in different countries to make it rain more or to fight droughts, but we're not sure if it can really help with pollution.
Some experts think that while rain can help clean the air for a little bit, cloud seeding might only give temporary relief. They believe that it's not a good idea to use resources on something that might not work well and only help for a short time. They say that we need to have a plan that everyone agrees on to fix the pollution problem, and that we need to listen to experts from different fields.
Other experts are worried that there isn't enough proof that cloud seeding will work, and that it might have some downsides. They think that we need to work together and come up with a big plan to fix the pollution problem, instead of trying little things here and there. It's important to think about what could happen in the long run and if there are any risks to changing how nature works.
In the end, the idea of using cloud seeding to fight air pollution in Delhi has made some people hopeful, but others are not so sure. While it might help for a little bit, experts think that we need a bigger and more sustainable plan to fix the pollution problem in the city.

Group or Classroom Activities
Warm-up Activities:
– Opinion Poll
Instructions: Split the class into small groups and give each group a statement about cloud seeding, such as "Cloud seeding is an effective long-term solution for pollution." Have students discuss within their groups whether they agree or disagree with the statement and why. After the discussion, conduct a class-wide poll to see where students stand on the issue.
– Speed Summarizing
Instructions: Pair up students and challenge them to summarize the article to their partner in just one minute. Afterward, have the partners switch roles. This will encourage students to focus on the key points and practice concise language use.
– Pros and Cons
Instructions: Ask students to list the pros and cons of using cloud seeding as a solution for pollution in Delhi. They can do this individually or in pairs. Then, bring the class together and have a discussion based on the lists they created, encouraging the use of specific vocabulary from the article.
– Future Predictions
Instructions: Invite students to write a short paragraph predicting the future of Delhi's air pollution situation. They should include whether they think cloud seeding will be used and what the potential outcomes might be. Encourage them to use modal verbs for speculation (e.g., might, could, should).
– Think-Pair-Share
Instructions: Pose a question to the class, such as "What alternative solutions could Delhi consider to address its air pollution problem?" Have students first think about their answer individually, then pair up to discuss their ideas, and finally share their thoughts with the larger group. This activity encourages critical thinking and speaking practice.
π€ Comprehension Questions:
The city of Delhi has been dealing with really bad air pollution.
The city's environment minister has suggested using cloud seeding to make it rain artificially.
Some experts are concerned that cloud seeding might not work well, could only provide temporary relief, and could potentially harm the environment in the long run.
Pollution in Delhi gets worse in the winter because of things like burning crops and slow-moving winds.
The Delhi government has tried to fix the problem by letting kids out of school early and stopping construction work.
Cloud seeding works by spraying tiny particles of salt onto clouds to make it rain. The right conditions for it to be successful include having enough moisture in the atmosphere and the right kind of wind. The salt particles need to be sprayed into clouds that are growing upwards.
Experts argue that cloud seeding might only give temporary relief, might not work effectively, and it's not a good use of resources. They stress the need for a long-term, agreed-upon plan to address the pollution problem.
Experts believe that a larger, more sustainable plan is necessary to effectively tackle the pollution problem in Delhi in the long term. They emphasize the importance of a comprehensive strategy that takes into account the potential long-term effects and risks.
