Chemistry for Teachers
Solved Exam Questions
Course Introduction
Chemistry for Teachers is designed to equip future educators with a solid foundation in fundamental chemical principles and effective instructional strategies. The course emphasizes the exploration of key topics such as atomic structure, chemical bonding, states of matter, chemical reactions, thermodynamics, and basic laboratory techniques, all tailored for secondary education settings. Students will engage with hands-on experiments and demonstrations, learn to develop lesson plans that align with curriculum standards, and explore methods for fostering inquiry-based learning and scientific literacy in the classroom. The course also addresses practical aspects of safety in the chemistry lab and ethical considerations in teaching science.
