Good day, kids! How are you today? Do you know that sun is considered as a star and one of the most important astronomical objects? Yes, because it provides light and warmth. Its motion through our sky causes day and night, and varied climates.
On any given day, the sun moves through our sky in the same way as a star. It seems to rise somewhere along the eastern horizon and seems to set somewhere in the west. But how does the height of the sun in the sky affect the amount of energy received in a certain place?
In this module, you will understand how the places across the globe vary in the amount of energy received from the sun. Knowing these skills is very essential in your future use especially in the field of science. What is the relationship of the sun’s position in the sky with the energy received by a certain place?

- Using models, relate the height of the sun in the sky to the amount of energy received.
This module focuses specifically on the angle of light.
After going through this module, you are expected to:
- describe how the height of the sun affects to the amount of energy received by a certain place on Earth; and
