Indicator

 

A.   Explain how processes at the cellular level affect the functions and characteristics of an organism.

1.   Describe how the maintenance of a relatively stable internal environment is required for the continuation of life, and explain how stability is challenged by changing physical, chemical and environmental conditions as well as the presence of pathogens.

2.   Recognize that chemical bonds of food molecules contain energy. Energy is released when the bonds of food molecules are broken and new compounds with lower energy bonds are formed. Some of this energy is released as thermal energy.

B.   Explain how humans are connected to and impact natural systems.

3.   Relate how birth rates, fertility rates and death rates are affected by various environmental factors.

4.   Examine the contributing factors of human population growth that impact natural systems such as levels of education, children in the labor force, education and employment for women, infant mortality rates, costs of raising children, birth control methods, and cultural norms.

5.   Investigate the impact on the structure and stability of ecosystems due to changes in their biotic and abiotic components as a result of human activity.

 

C.   Explain how the molecular basis of life and the principles of genetics determine inheritance.

N/A

 

D.   Relate how biotic and abiotic global changes have occurred in the past and will continue to do so in the future.

9.       Recognize that ecosystems change when significant climate changes occur or when one or more new species appear as a result of immigration or speciation.

10.   Describe how the process of evolution has changed the physical world over geologic time.

14.  Describe how geologic time can be estimated by observing rock sequences and using fossils to correlate the sequences at various locations. Recognize that current methods include using the known decay rates of radioactive isotopes present in rocks to measure the time since the rock was formed.

 

E.   Explain the interconnectedness of the components of a       natural system.

11.   Predict some possible impacts on an ecosystem with the introduction of a non-native species.

7.   Show how populations can increase through linear or   exponential growth with corresponding effects on resource use and environmental pollution.

 

F.   Explain how human choices today will affect the quality and quantity of life on Earth.

12.   Recognize that populations can reach or temporarily exceed the carrying capacity of a given environment. Show that the limitation is not just the availability of space but the number of organisms in relation to resources and the capacity of earth systems to support life.

13.   Give examples of how human activity can accelerate rates of natural change and can have unforeseen consequences.

14.   Explain how environmental factors can influence heredity or development of organisms.

11. Investigate issues of environmental quality at local, regional, national and global levels such as population   growth, resource use, population distribution, over-consumption, the capacity of technology to solve problems, poverty, the role of economics, politics and different ways humans view Earth.

 

G.   Summarize the historical development of scientific theories and ideas within the study of life science.

N/A

 

H.   Explain the cell structure and describe organelle function affect.

15.   Describe the cell; it organelles and their functions.

16.  Describe how the cell interacts with its environment.

 

I.    Use directional terms to identify the levels of structural organization of the body and the primary regions of the body.

17.  Use the basic terminology to describe the human body is       directional and locational (body planes).

18.  Organize and describe the five structural levels of body       organization.

19.  Identify the primary regions of the body, locate major body cavities, and lists the organs they contain.

 

J.    Define homeostasis and its importance to survival.

20.  Compare and contrast how homeostasis regulation and maintenance is affected by the integumentary, skeletal, and muscular systems.

 

K.   Compare and contrast the structure and functions of the different human systems.

21.  Identify the divisions of the nervous system, their structures, functions, organs, and roles in controlling and maintaining homeostatic balance.

22.  Describe the circulatory cardiovascular, and lymphatic systems.

23.  Identify the location, feature, structure, functions, conduction systems, and pathways of the cardiovascular system.

24.  Investigate major heart disease and conditions, their causes, effects and treatment.

25.  Examine the role, structures, components, and effects of the lymphatic system.

26.  Identify the organs, functions, and role of the respiratory system in meeting the metabolic needs of the body.

27.  Describe the impact of smoking and disease factors on the respiratory system.

28.  Trace the mechanics of breathing to the exchange of gases in external and internal respiration.

29.  Identify and describe the functions and structural features of the urinary system.

30.  Trace the process of elimination through the urinary system.

31.  Describe urinalysis and interpret the information it provides.

32.  Identify the organs, structure, and functions of the male and female reproductive organs.

33.  Compare and contrast the female and male neural and hormonal mechanisms in reproduction.

34.  Examine diseases and dysfunctions of the reproductive       system.

 

L.   Describe the stages of development in humans.

35.  Describe prenatal, parturition, and postnatal development in humans.

36.  Discuss the five stages of life.
