8th Grade Science Class

Quarter 1: Earth Systems, Structures and Processes

Explain the structure of the hydrosphere including: • Water distribution on earth • Local river basins and water availability

Summarize evidence that Earth’s oceans are a reservoir of nutrients, minerals, dissolved gases, and life forms: Estuaries, Marine ecosystems,Upwelling, Behavior of gases in the marine environment, Value and sustainability of marine resources, Deep ocean technology and understandings gained

Predict the safety and potability of water supplies in North Carolina based on physical and biological factors, including: Temperature, Dissolved oxygen, pH, Nitrates and phosphates, Turbidity, Bio-indicators

Conclude that the good health of humans requires: Monitoring of the hydrosphere, Water quality standards, Methods of water treatment, Maintaining safe water quality, and Stewardship

Quarter 2: Matter: Properties and Change

Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements.

Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements.

Compare physical changes such as size, shape and state to chemical changes that are the result of a chemical reaction to include changes in temperature, color, formation of a gas or precipitate.

Explain how the idea of atoms and a balanced chemical equation support the law of conservation of mass.

Quarter 3: Energy: Conservation and Transfer

Explain the environmental consequences of the various methods of obtaining, transforming and distributing energy.

Explain the implications of the depletion of renewable and nonrenewable energy resources and the importance of conservation.

Quarter 3: Earth History

8.E.2.1 Infer the age of Earth and relative age of rocks and fossils from index fossils and ordering of rock layers (relative dating and radioactive dating). 8.E.2.2 Explain the use of fossils, ice cores, composition of sedimentary rocks, faults, and igneous rock formations found in rock layers as evidence of the history of the Earth and its changing life forms.

Quarter 3: Evolution and Genetics

Summarize the use of evidence drawn from geology, fossils, and comparative anatomy to form the basis for biological classification systems and the theory of evolution.

Explain the relationship between genetic variation and an organism’s ability to adapt to its environment.

Quarter 4: and Functions of Living Organisms

Summarize the basic characteristics of viruses, bacteria, fungi and parasites relating to the spread, treatment and prevention of disease.

Explain the difference between epidemic and pandemic as it relates to the spread, treatment and prevention of disease.

Understand how biotechnology is used to affect living organisms.

Summarize aspects of biotechnology including: Specific genetic information available, Careers, Economic benefits to North Carolina, Ethical issues, and Implications for agriculture

Quarter 4: Ecosystems

Explain how factors such as food, water, shelter and space affect populations in an ecosystem.

Summarize the relationships among producers, consumers, and decomposers including the positive and negative consequences of such interactions including: Coexistence and cooperation, Competition (predator/prey), Parasitism, and Mutualism

Explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide and oxygen).

Quarter 4: Molecular Biology

Summarize how food provides the energy and the molecules required for building materials, growth and survival of all organisms (to include plants).

Explain the relationship among a healthy diet, exercise, and the general health of the body (emphasis on the relationship between respiration and digestion).
