Class 5 EVS Chapter 13 Our Environment and Pollution @kidsknowledgepoint


The environment is everything around us, including air, water, soil, plants, and animals. It provides us with everything we need to live, like clean air to breathe, water to drink, and food to eat. But sadly, our environment is getting polluted, which is harming all living things.

What is Pollution?

Pollution is when harmful substances are added to our environment, making it dirty and unhealthy. These substances are called pollutants, and they come from different sources.

Types of Pollution

  1. Air Pollution

    • What is it? Air pollution happens when harmful gases, smoke, and dust are released into the air.
    • Sources: Factories, vehicles, burning garbage, and smoke from chimneys.
    • Effects: It causes breathing problems, allergies, and makes the air unhealthy.

  2. Water Pollution

    • What is it? Water pollution occurs when harmful substances mix with water bodies like rivers, lakes, and oceans.
    • Sources: Throwing garbage, chemicals from factories, and sewage waste into water.
    • Effects: It kills fish and other water animals, and makes the water unsafe for drinking.

  3. Soil Pollution

    • What is it? Soil pollution happens when harmful chemicals and waste make the soil dirty.
    • Sources: Plastic waste, pesticides, chemicals from factories, and oil spills.
    • Effects: It reduces the quality of soil, making it difficult for plants to grow.

  4. Noise Pollution

    • What is it? Noise pollution is when there is too much loud sound around us.
    • Sources: Honking vehicles, loudspeakers, construction work, and factory machines.
    • Effects: It causes stress, hearing problems, and disturbs our sleep.

How Can We Reduce Pollution?

  • Plant more trees: Trees clean the air and provide fresh oxygen.
  • Use public transport or cycle: This reduces the number of vehicles on the road, which helps reduce air pollution.
  • Avoid using plastic: Use cloth bags instead of plastic bags.
  • Save water: Turn off taps when not in use to prevent water wastage.
  • Recycle and reuse: Recycle paper, glass, and plastic to reduce waste.

Conclusion

Pollution is a big problem that harms our environment and health. We must all work together to reduce pollution and protect our environment for a cleaner and healthier world.

What to Expect in a Grade 2 Math Olympiad Exam Math Olympiad exams for Grade 2 are designed to challenge young students and spark their interest in mathematics. These exams test a range of skills from basic arithmetic to problem-solving and pattern recognition. Here’s a look at the types of questions Grade 2 students might encounter in a Math Olympiad and some tips on how to prepare. Types of Questions in the Grade 2 Math Olympiad Basic Arithmetic Addition and Subtraction: Students are expected to perform basic addition and subtraction operations. For example: "What is 23 + 15?" "If you have 17 apples and you eat 5, how many apples are left?" Multiplication and Division: Though more advanced, simple multiplication and division problems may appear: "What is 4 × 3?" "Divide 12 cookies among 4 friends. How many cookies does each friend get?" Patterns and Sequences Students will need to identify and extend patterns in numbers or shapes. Examples in...

What are Large Numbers? Large numbers are numbers that go beyond the basic hundreds and thousands that students learned in earlier grades. In Grade 4, students typically learn about numbers up to 100,000 or even more, which includes understanding place value, comparing, and working with these numbers in addition, subtraction, and beyond. Why Are Large Numbers Important? Develops Number Sense: Learning large numbers helps students understand the size and value of numbers. They learn how numbers grow, how place value works, and how to read and write them correctly. Real-Life Applications: Large numbers are everywhere in real life! For example, populations of cities, distances between planets, prices of cars, and scores in video games often involve big numbers. Understanding large numbers helps students make sense of these real-world examples. Builds Mathematical Foundation: Mastering large numbers is essential for more advanced math topics like multiplication, division, fractions, and ev...
