Physical Science Module 8: Expanding Universe

Welcome to Physical Science Grade 11/12 Alternative Delivery Mode (ADM) Module on the topic Models of the Universe (Greek Astronomy to Kepler)!

Our hands are the most represented parts of the human body. It is often used to depict skill, action, and purpose. With our hands, we create, accomplish and learn. Hence, you are capable and empowered to successfully achieve the relevant competencies and skills at your own pace and time. Your academic success lies in your own hands!

This module was designed to provide you with fun and meaningful opportunities for guided and independent learning at your own pace and time. You will be able to process the contents of the learning resource while being an active learner.

This module will help you understand the evolution and expansion of the universe through approximation of distance and movement of stars and galaxies. This module will provide you with discussions and learning activities designed to be easily understood.

CONTENT STANDARD: The learners demonstrate an understanding of Relativity and the Big Bang.

PERFORMANCE STANDARD: The learners should be able to create a video presentation that details the impact of the Theory of Relativity to human.

LEARNING COMPETENCIES: The learners must explain how the speeds and distances of far-off objects are estimated (e.g., Doppler Effect and Cosmic Distance Ladder) and explain how we know that we live in an expanding universe which used to be hot and is approximately 14 billion years old.

  • Lesson 1 – Astrometry and Cosmology

After going through this module, you are expected to:

1. Explain the different ways in which the speed and distance of celestial objects are estimated; and

2. Explain the various pieces of evidence for the theory of an expanding universe.
