Learning outcome

Predict and describe the physical Critical Thinking and Problem Solving: GESI: and chemical properties of the Learners think critically and communicate as they discuss Embrace diversity and practice halogens as well as their uses in variations and anomalies in physical properties of the halogens. inclusion as they communicate to everyday life. explore the uses of the reactions of Learners think critically as they discuss electron configurations halogens in everyday life. and variable oxidation states of the halogens and link them to Interrogate their stereotypes and their chemical properties. biases about gender as they deduce the Learners brainstorm to deduce the differences in the reactivity differences in the reactivity of the of the halogens based on their electrode potential. halogens. Refute misconceptions/myths about Communication and Collaboration: gender and disabilities as they Learners communicate as they dialogue in pairs to explain the demonstrate and carryout chemical basis for the uses of the reactions of halogens in investigation. everyday life. Learners collaborate as they work in mixed-ability groups. Provide opportunities for learners to SEL: Learners communicate and think critically as they engage in evaluate their own work on writing discourse and write balanced chemical equations. chemical equations involving halogens. Demonstrations and carrying out investigations make learners creative. National Core Values: Respect Learners practice digital learning by watching a Digital Learning: Open-mindedness video on the reaction of the halogens with water. CHEMISTRY
