Up in the Sky

Stars in the Sky for Class 2 Science

The area we see above the Earth where stars, sun, and moon can be seen is called the sky.
At night, various stars in the sky make a constellation. These constellations are named based on their shapes which make them unique. The following concept will introduce the learners to the changes visible in the sky at various times of the day.

After reading the concept, students will be able to:

  • State the meaning of the terms dawn, noon and dusk.
  • Define constellation.
  • Identify Saptarishi constellation and pegasus constellation.

Each concept is explained to class 2 students using examples, illustrations, and concept maps. After you go through a concept, assess your learning by solving the two printable worksheets given at the end of the page.

  • We see the sky when we look up above the land.
  • The sky appears blue on a clear day. It looks different during different weather.
  • At night, we see many bright and shining heavenly bodies in the sky. These are called celestial bodies.
  • Stars are a type of celestial body. They have their own light and hence shine bright in the night sky.

3)Sky During Noon:

  • At noon, the sun remains above our heads.
  • During noon the sky appears white. As the sun remains overhead, minimal light gets scattered, so the sky looks white.

4)Sky During Dusk:

  • During dusk, the sun sets in the west. The sun looks like a red ball and appears on the horizon.
  • After the Sun sets, no more sunlight gets scattered, which is why the sky appears dark in colour and gradually turns black.

Stars:

  • The stars are giant balls of fiery gases. But they are situated far away and so appear like small twinkling objects.
  • So, they shine brightly in the night sky.
  • A group of stars is called a constellation, like Orion and Saptarishi.
