Description
Dear Learner,
This online module aims to engage learners like you through interactive activities and real-world examples, fostering a deeper appreciation of chemistry’s foundational principles, measurements and experimental methodologies, and atomic structure, preparing them to apply this knowledge in practical contexts and understand its broader implications in scientific research and industry, with a particular focus on Ethiopia.
This module is structured to be engaging, informative, and relevant to learners interested in understanding how chemistry shapes our world and contributes to sustainable development in Ethiopia and beyond.
The first unit of this module aims to provide Grade 9 learners with a foundational understanding of chemistry’s scope, its interdisciplinary nature, and its practical applications within the context of Ethiopian industries and society.
The second unit of this module aims to equip Grade 9 learners with foundational skills in measurements and scientific methods essential for understanding chemistry. Through engaging and interactive learning experiences, learners will gain practical knowledge applicable to their academic studies and future scientific endeavors.
The final unit of this module is designed to introduce Grade 9 learners in Ethiopia to the fundamental concepts of the structure of an atom. Learners will explore the historical development of atomic theories, the properties of subatomic particles, and the composition of atoms. Through interactive lessons, and practical exercises, learners will develop a comprehensive understanding of atomic structure and its significance in chemistry.
Competencies
Up on the completion of this module, you should be able to:
