About this course
This unit introduces key principles in chemistry, beginning with the Periodic Table, which organizes elements based on their properties and behaviors. Learners explore the periodic law, element classification into metals, non-metals, metalloids, and transition metals, and the arrangement into S, P, D, and F blocks. The lessons highlight trends such as atomic size, ionization energy, electron affinity, and diagonal relationships, helping students understand how the table predicts chemical behavior.
Next, the unit covers Chemical Reactions, focusing on how substances interact to form new compounds. Using collision theory, learners examine how temperature, pressure, and catalysts affect reaction rates. The module also explores energy changes in reactions, distinguishing between exothermic and endothermic processes, and introduces chemical equilibrium and Le Chatelier’s principle to explain how systems respond to changes.
The third section, Mass-Volume Relationships, emphasizes the importance of accurate measurements in chemistry. Students learn the mole concept, molar mass, molar volume, and relative densities. These tools are applied using SI units and structured problem-solving techniques to ensure precision in laboratory and industrial settings.
In Acid-Base Reactions, learners study how acids and bases regulate pH in biological and industrial systems. The lessons introduce titration methods, standard solutions, indicators, and concentration measurements. Emphasis is placed on precision in recording titre values and performing calculations to ensure reliable chemical analysis.
The unit concludes with a focus on Water: Properties and Hardness. Students explore water’s molecular structure, hydrogen bonding, and its role as a solvent. Lessons cover solute-solvent interactions, solubility curves, and the causes and effects of water hardness. Techniques for water purification and treatment are also discussed, highlighting the importance of clean water in daily life and industry.
Throughout the unit, learners engage with multimedia content and guided exercises. Opportunities for feedback and coaching sessions support deeper understanding and practical application.
The unit equips students with essential chemistry knowledge, preparing them to analyze, measure, and apply chemical principles responsibly and effectively.
