11. Human Body & systems / Life processes

        Basic description of systems (nervous, endocrine, circulatory, etc.,)

        Maintenance of homeostasis for each

        Malfunction of each/ example of a disease and symptom

 

12. Feedback Mechanisms (Homeostasis)

        Insulin and blood sugar level

        Stomates/guard cells

 

13. Disease/Vaccines

        Microbes, pathogens, antibodies, host, etc.,

        Explain vaccines

      What they are

      How they are made/tested

      How they work in the body

        Disruption of homeostasis

 

14. Evolutionary theories
