1. Grade 9 Science at Ancaster HS

2. What is in Grade 9 Science? Both the applied and academic programs cover the same overall units of study There are five areas of study or skill development

3. Units We Look At 1. Scientific Skill Development 2. Sustainable Ecosystems 3. Atoms, Elements and Compounds 4. The Study of the Universe 5. The Characteristics of Electricity

4. How is Applied Different From Academic? The method of teaching the material and the application of the topics is different Our Applied courses focus on hands on application of theory You get to try labs many times to help you understand a theory Academic courses focus more on the theory’s impact in society or the environment
