Understanding Valence Electrons and Bonding

This week's lesson for grade eight covers bonding and the periodic table. The teacher outlines objectives, including identifying halogens and noble gases, understanding valence electrons, and their role in bonding. Students will engage with interactive periodic tables, solve worksheets, read articles, and watch videos to deepen their understanding. The lesson concludes with a reminder to use online quizzes for self-assessment and an invitation to reach out with questions.
