SCIENCE NORTH CAROLINA STANDARD COURSE OF STUDY
MATTER: PROPERTIES AND CHANGE 8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container. 8.P.1.1 Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements. 8.P.1.2 Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements. 8.P.1.3 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. 8.P.1.4 Explain how the idea of atoms and a balanced chemical equation support the law of conservation of mass. ENERGY: CONSERVATION AND TRANSFER 8.P.2 Explain the environmental implications associated with the various methods of obtaining, managing, and using energy resources. 8.P.2.1 Explain the environmental consequences of the various methods of obtaining, transforming and distributing energy. 8.P.2.2 Explain the implications of the depletion of renewable and nonrenewable energy resources and the importance of conservation. EARTH SYSTEMS, STRUCTURES AND PROCESSES 8.E.1 Understand the hydrosphere and the impact of humans on local systems and the effects of the hydrosphere on humans. 8.E.1.1 Explain the structure of the hydrosphere including: • Water distribution on earth • Local river basins and water availability 8.E.1.2 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 8.E.1.3 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 8.E.1.4 Conclude that the good health of humans requires: • Monitoring of the hydrosphere • Water quality standards • Methods of water treatment • Maintaining safe water quality • Stewardship EARTH HISTORY 8.E.2 Understand the history of Earth and its life forms based on evidence of change recorded in fossil records and landforms. 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. STRUCTURES AND FUNCTIONS OF LIVING ORGANISMS 8.L.1 Understand the hazards caused by agents of diseases that effect living organisms. 8.L.1.1 Summarize the basic characteristics of viruses, bacteria, fungi and parasites relating to the spread, treatment and prevention of disease. 8.L.1.2 Explain the difference between epidemic and pandemic as it relates to the spread, treatment and prevention of disease. 8.L.2 Understand how biotechnology is used to affect living organisms. 8.L.2.1 Summarize aspects of biotechnology including: • Specific genetic information available • Careers • Economic benefits to North Carolina • Ethical issues • Implications for agriculture ECOSYSTEMS 8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment. 8.L.3.1 Explain how factors such as food, water, shelter and space affect populations in an ecosystem. 8.L.3.2 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 • Mutualism 8.L.3.3 Explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide and oxygen). EVOLUTION AND GENETICS 8.L.4 Understand the evolution of organisms and landforms based on evidence, theories and processes that impact the Earth over time. 8.L.4.1 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. 8.L.4.2 Explain the relationship between genetic variation and an organism’s ability to adapt to its environment. MOLECULAR BIOLOGY 8.L.5 Understand the composition of various substances as it relates to their ability to serve as a source of energy and building materials for growth and repair of organisms. 8.L.5.1 Summarize how food provides the energy and the molecules required for building materials, growth and survival of all organisms (to include plants). 8.L.5.2 Explain the relationship among a healthy diet, exercise, and the general health of the body (emphasis on the relationship between respiration and digestion). EXTENDED CONTENT STANDARDS FORCES AND MOTION EX.8.P.2 Understand that energy has the ability to cause motion or create change. EX.8.P.2.1 Identify forms of energy, such as light, heat, electrical, and energy of motion. EX.8.P.2.2 Describe the results of applying electrical energy (turn on lights, make motors run); heat energy (burn wood, change temperature); and energy of motion (go faster, change direction). EX.8.P.2.3 Identify that a hot object will make a cold object warm when they touch. MATTER, PROPERTIES AND CHANGE EX.8.P.1 Understand the interactions of matter and energy and the changes that occur. EX.8.P.1.1 Identify that a whole object weighs the same as all of its parts together. EARTH SYSTEMS, STRUCTURES AND PROCESSES EX.8.E.1 Understand the hydrosphere. EX.8.E.1.1 Identify water features on the earth’s surface (oceans, lakes, rivers, glaciers). EX.8.E.1.2 Compare Earth’s saltwater and freshwater features (oceans, lakes, rivers). EX.8.E.1.3 Understand that human health requires monitoring of the hydrosphere and stewardship (e.g. water conservation, pollution). STRUCTURES AND FUNCTIONS OF LIVING ORGANISMS EX.8.L.1 Understand that germs can cause disease. EX.8.L.1.1 Recognize that germs can cause illness. EX.8.L.1.2 Identify illnesses that may be caused by germs. EX.8.L.1.3 Demonstrate hygienic practices that reduce the presence of germs. EX.8.L.1.4 Describe minor treatments to prevent infection and the spread of disease (Band-Aid on cut; Cover mouth for sneeze or cough; Use and disposal of tissues). ECOSYSTEMS EX.8.L.2 Explain the interdependence of living organisms in the environment. EX.8.L.2.1 Identify that in a simple food chain, energy transfers from the Sun to plants (producers), to animals (consumers), and to organisms that cause decay (decomposers). EX.8.L.2.2 Understand the relationship between living things and their environment. |
