Grade 11 Chemistry
Scope
Chemistry is the study of matter and the interactions that matter undergoes. The structure, properties, and changes that matter undergoes are studied from both particulate and bulk (macroscopic) perspectives. The energy transformations that occur during physical, chemical, and nuclear changes are also key and help students make predictions and justifications of the phenomena they observe. Physical and mathematical models are used to enhance learning and aid in the explanation of various physical and chemical concepts/processes.
