Module 8: Non-infectious Disease and Disorders    Revision 1 Revision 2 Revision 3

Homeostasis

Inquiry question: How is an organism’s internal environment maintained in response to a changing external environment?

Students:

● construct and interpret negative feedback loops that show homeostasis by using a range of sources, including but not limited to:

– temperature glucose

● investigate the various mechanisms used by organisms to maintain their internal environment within tolerance limits, including:

– trends and patterns in behavioural, structural and physiological adaptations in endotherms that assist in maintaining homeostasis

– internal coordination systems that allow homeostasis to be maintained, including hormones and neural pathways

– mechanisms in plants that allow water balance to be maintained

Causes and Effects

Inquiry Do non-infectious diseases cause more deaths than infectious diseases?:question

Students:

● investigate the causes and effects of non-infectious diseases in humans, including but not limited to:

– genetic diseases

– diseases caused by environmental exposure

– nutritional diseases

– cancer

● collect and represent data to show the incidence, prevalence and mortality rates of non-infectious diseases, for example:

– nutritional diseases

– diseases caused by environmental exposure

Epidemiology

Inquiry question: Why are epidemiological studies used?

Students:

● analyse patterns of non-infectious diseases in populations, including their incidence and prevalence, including but not limited to:

– nutritional diseases

– diseases caused by environmental exposure

● investigate the treatment/management, and possible future directions for further research, of a non-infectious disease using an example from one of the non-infectious diseases categories listed above

● evaluate the method used in an example of an epidemiological study

● evaluate, using examples, the benefits of engaging in an epidemiological study

Prevention

Inquiry question: prevented? be How can non-infectious diseases

Students:

● use secondary sources to evaluate the effectiveness of current disease-prevention methods and develop strategies for the prevention of a non-infectious disease, including but not limited to:

– educational programs and campaigns

– genetic engineering

Technologies and Disorders

Inquiry question used to assist people who experience disorders? be: How can technologies

Students:

● explain a range of causes of disorders by investigating the structures and functions of the relevant organs, for example:

– hearing loss

– visual disorders

– loss of kidney function

● investigate technologies that are used to assist with the effects of a disorder, including but not limited to:

–  hearing loss: cochlear implants, bone conduction implants, hearing aids

– visual disorders: spectacles, laser surgery

– loss of kidney function: dialysis

● evaluate the effectiveness of a technology that is used to manage and assist with the effects of a disorder
