it was the month of may. the school had reopened after the annual results.
I was promoted to the higher class and was very excited about it. My bag was full of new books. My uniform was brand new. I was walking briskly towards the school. Suddenly, there were dark clouds in the sky. They soon spread and covered the sun. I started running towards the school and when I was barely a 100 meters away from the school it started pouring hard .I ran towards a tree and stood under it for some time but the rain did not stop. Soon, water drops started drenching me to the marrow. I tried to save my bag to no avail. My shoes and socks were so full of water that I started feeling a numbness in my feet. At last,I took up the risk and started running towards the school. My shoes threw mud all over my back. When I reached school building I took shelter in the porch. I immediately opened my bag and tried to rescue my books and notebooks.The cardboard wrapper of pastel chalks that were meant for the drawing period had got torn.The chalks had become pulp and their color was splashed on my books and notebooks.
I removed my shoes and shocks and left them to dry. I looked awkward. Since then, I never forgetto take my umbrella along the raining season.

- They gain public support and confidence for their goals and activities by carrying out information campaigns, organising meetings, filing petitions, etc.
- They hold strikes and by disrupting the government's programmes, they force the government to look into their demands.
- Many business groups often employ professional lobbyists to influence the government policies.

a² + b² + c² = ab + bc + ca
On multiplying both sides by “2”, it becomes
2 ( a² + b² + c² ) = 2 ( ab + bc + ca)
2a² + 2b² + 2c² = 2ab + 2bc + 2ca
a² + a² + b² + b² + c² + c² – 2ab – 2bc – 2ca = 0
a² + b² – 2ab + b² + c² – 2bc + c² + a² – 2ca = 0
(a² + b² – 2ab) + (b² + c² – 2bc) + (c² + a² – 2ca) = 0
(a – b)² + (b – c)² + (c – a)² = 0
=> Since the sum of square is zero then each term should be zero
⇒ (a –b)² = 0, (b – c)² = 0, (c – a)² = 0
⇒ (a –b) = 0, (b – c) = 0, (c – a) = 0
⇒ a = b, b = c, c = a
∴ a = b = c.

Albert Einstein's theory of education is based on reasoning and logic. He believed that education is not about learning facts but thinking about ideas. Education according to him is not something to mug up like remembering the year of battle or any event but the reason why it all started.

Plants which live in water ecosystem like lakes, rivers, ponds, bogs etc. face many problems. The most common are low oxygen content, low light intensity, lack of soil, and nutrients.
-
Some of these issues are resolved by floating in water streams. Aquatic plants develop in a way such that their roots are in the water, but the upper half partially emerges from the surface of the water for efficient photosynthesis.
-
Food, nutrients, and air are absorbed through modified stems and roots.

Food web is a network of food chains where all the chains are naturally interconnected.
Each organism is generally eaten by two or more kinds or organisms which are again eaten by several other organisms and so instead of straight line food chain, the series of organisms dependent on one another food can be shown by branched lines which is called as a food web.
Flow of energy in a food chain is unidirectional, once it reaches the next tropic level it does not come back again.
For example- energy which passes to the herbivores does not come back again to autotrophs.

| Biotic Resources | Abiotic Resources |
|
Definition |
|
| Biotic factors include all the living components present in an ecosystem | Abiotic factors refer to all the non-living, i.e. physical conditions and chemical factors that influence an ecosystem |
|
Examples |
|
| Examples of biotic resources include all flora and fauna | Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity, precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc. |
|
Dependence |
|
| Biotic factors depend on abiotic factors for survival and reproduction | Abiotic factors are completely independent of biotic factors |
|
Origin |
|
| Biotic components originate from the biosphere | Abiotic components originate from the lithosphere, hydrosphere and atmosphere |

A biodegradable substance can be defined as a material which can be decomposed by microorganisms or decomposers and not be adding to any type of pollution. Waste that cannot be decomposed by the biological ways is called the Non-biodegradable wastes

| Biodegradable waste | Non-biodegradable waste |
| Those which can be easily degraded by the decomposers into substances that go into soil and are harmless to the environment. | Those which cannot be degraded by the decomposers and thus remain in the environment causing pollution. |
| They are natural wastes. | They are synthetic wastes. |
| Examples- vegetables wastes, animal excreta | Examples- plastic, polythene |

The trophic level is the position an organism occupies in the food chain. The first trophic level known as the base of the ecosystem has the highest energy concentration which is transferred to the organisms at different trophic levels. Following are the different levels of an ecosystem:
- Producers: Plants and other autotrophs are known as producers. They prepare their own food using sunlight and carbon dioxide by the process of photosynthesis. This energy is transferred to the organisms that feed on the producers.
- Primary Consumers: This is the second trophic level which includes all the herbivores. Animals such as cows, buffaloes, deer, few insects cannot prepare their food and rely on plants and natural products for nutrition.
- Secondary Consumers: A few organisms such as rats, foxes, fish belong to the third trophic level. These are secondary consumers and derive their nutrition from the primary consumers.
- Tertiary Consumers: This is the fourth trophic level that includes all the carnivores and omnivores.
- Apex Predators: This is the final trophic level of the ecosystem. The animals belonging to this trophic level have no predators of their own. Eagles, lions, anacondas, belong to this trophic level.

Following are some points that would help in preventing this problem at a global level:
Avoid Using Pesticides: Natural methods should be implemented to get rid of pests and weeds instead of using chemicals. One can use eco-friendly chemicals to remove the pests or remove the weeds manually.
Minimize the Use of Vehicles: The vehicles emit a large amount of greenhouse gases that lead to global warming as well as ozone depletion. Therefore, the use of vehicles should be minimized as much as possible.
Use Eco-friendly Cleaning Products: Most of the cleaning products have chlorine and bromine releasing chemicals that find a way into the atmosphere and affect the ozone layer. These should be substituted with natural products to protect the environment.
Use of Nitrous Oxide should be Prohibited: The government should take actions and prohibit the use of harmful nitrous oxide that is adversely affecting the ozone layer. People should be made aware of the harmful effects of nitrous oxide and the products emitting the gas so that its use is minimized at the individual level as well.

भारत मेलों का देश है यहां पर हर रोज कहीं ना कहीं मेला लगा ही रहता है. मुझे मेले में जाना बहुत अधिक पसंद है हमारे गांव में हर साल दशहरा के दिन मेला भरता है. मेला दशहरा के दिन सुबह लगता है और रात 10:00 बजे तक मेले में चहल पहल रहती है.
दशहरा के दिन हमारे विद्यालय की छुट्टी होने के कारण हम पूरे दिन मेले में ही रहते है. मेले वाले दिन हम सुबह-सुबह नए कपड़े पहन कर तैयार हो जाते हैं फिर मैं अपने दोस्तों के पास जाता हूं फिर हम सब मिलकर मेले में जाते है. मेले में जाने के बाद हम खूब मस्ती करते हैं झूला झूलते हैं समोसे, कचोरी, गोलगप्पे खाते है.
मेले में कई प्रकार के कार्यक्रम होते है. उन सभी कार्यक्रमों को हम बड़े चाव से देखते है. मेले में कई जादूगर आते हैं जो कि जादू दिखाते है. पूरा मेला देखने के बाद हम शाम को घर लौट आते है.

लेखक बताता है कि स्पीति में वर्षा बहुत कम होती है। इस कारण वर्षा ऋतु मन की साध पूरी नहीं करती। वर्षा के बिना यहाँ की धरती सूखी, ठंडी व बंजर होती है। जब कभी यहाँ वर्षा हो जाती है तो लोग इसे अपना सुखद सौभाग्य मानते हैं। वर्षा के दिन को वे सुख का संकेत मानते हैं। लेखक के आने के बाद यहाँ वर्षा हुई। लोगों ने उसे बताया कि वर्षा होने के कारण आपकी यात्रा सुखद होगी।
