Study Notes
Physical Science - Quarter 1 - Module 1: Formation of Heavy Elements
- This module explains the formation of heavy elements, focusing on how stars formed elements.
- It covers stellar nucleosynthesis, the different stages of a star's life cycle, and the formation of heavy elements during stellar nucleosynthesis and evolution.
- The module includes activities, like filling out graphic organizers and reading illustrations, to support learning.
- A pre-test is recommended before starting the module (skip if 100% correct ), and a post-test is at the end to gauge understanding.
- The module incorporates 21st-century skills and learner needs.
