This video series is a three-part supplementary learning material designed to complement the activity in the self-learning module on Ionic and Covalent Bonding. It highlights a demonstration of the activity, Isn’t it Ionic?, and its post-activity discussion on how ions and chemical bonds (ionic and covalent) are formed and how ionic and covalent compounds are recognized based on their properties. Aligned with the Grade 9 Science curriculum of the new DepEd MATATAG agenda, this video aims to provide learners with opportunities to deepen their understanding of chemical bonding, from theoretical foundations to practical implications.
The first part of the video series highlights the hands-on demonstration of the activity. Common household items are used in this activity where their intrinsic properties, or properties that are natural to them, are observed. This video presents the step-by-step procedure in performing the activity and the guide questions that are needed to be answered. It also discusses the results of the experiment, answers to the guide questions, as well as an introduction to types of chemical bonds, focusing on ionic bonding.
This video supports learners in understanding ionic bonds and in recognizing that the formation of these bonds involves transferring of valence electrons between atoms and generating oppositely charged ions.
