Class 5 EVS Chapter 11 The Sun , Earth and Moon-light and Shadows @kidsk...


  1. The Sun:

    • The Sun is a star that provides light and heat to Earth.
    • It is the primary source of energy for all life on Earth.
    • The Sun’s light enables us to see objects and creates shadows.

  2. Earth:

    • Earth revolves around the Sun and rotates on its axis.
    • This rotation causes day and night, while revolution leads to the seasons.

  3. Moon:

    • The Moon is Earth’s natural satellite and reflects sunlight.
    • It has phases due to its changing position relative to the Earth and Sun.

  4. Light and Shadows:

    • Light: Travels in a straight line and helps us see things.
    • Shadows: Form when an object blocks light.
      • Opaque objects block light fully, creating dark shadows.
      • Translucent objects allow some light, forming faint shadows.
      • Transparent objects allow light to pass through completely, so no shadow is formed.

Importance for Students:

  • Understanding these concepts helps students learn about the relationship between the Sun, Earth, and Moon.
  • Knowing how shadows form enhances spatial awareness and knowledge of light’s properties.
  • It builds a foundation for higher-level topics in physics and astronomy.

This chapter encourages curiosity about celestial bodies and promotes practical thinking by observing daily occurrences like the formation of shadows.

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...
