A lesson plan for a physical science class that covers the topic of polarity of molecules based on their structure. The lesson aims to help students understand how the polarity of chemical bonds is determined by the differences in electronegativity between the atoms involved. The plan includes objectives, subject matter, materials, and a detailed procedure with priming activities, a lesson proper, analysis questions, and an assessment. A comprehensive overview of the key concepts related to molecular polarity, including the relationship between electronegativity and bond polarity, as well as practical applications such as the principle of 'like dissolves like'. The lesson plan is designed to engage students through interactive activities and assessments, promoting their understanding of this fundamental topic in physical science.

Republic of the Philippines Department of Education Region IV-A CALABARZON Lesson Plan in Physical Science Content Standard : The learners demonstrate understanding of how the uses of different materials are related to their properties and structures. Performance Standard: The learners make a list of polar and non-polar products at home and their practical uses. I. OBJECTIVE At the end of the lesson, the students will be able to: a. identify if a molecule is polar or nonpolar b. determine the polarity of chemical bonds between atoms using the concept of electronegativity.

Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons toward itself.. Polar covalent bonds result when electrons are unequally shared between atoms, while nonpolar covalent bonds result when electrons are more equally shared between atoms. The unequal sharing of electrons is due to the differences in the electronegativities of the two atoms sharing the electrons. D. Analysis Questions:
