    • SC.8.L.18.2 Describe and investigate how cellular respiration breaks down food to provide energy and releases carbon dioxide.

    • SC.8.L.18.3 Construct a scientific model of the carbon cycle to show how matter and energy are continuously transferred within and between organisms and their physical environment.

    • SC.8.L.18.4 Cite evidence that living systems follow the Laws of Conservation of Mass and Energy.

SC.8.N Nature of Science

  • SC.8.N.1 The Practice of Science

    • A Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation.

    • B The processes of science frequently do not correspond to the traditional portrayal of "the scientific method."

    • C Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge.

    • D Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

    • SC.8.N.1.1 Define a problem from the eighth grade curriculum using appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.

    • SC.8.N.1.2 Design and conduct a study using repeated trials and replication.

    • SC.8.N.1.3 Use phrases such as "results support" or "fail to support" in science, understanding that science does not offer conclusive 'proof' of a knowledge claim.

    • SC.8.N.1.4 Explain how hypotheses are valuable if they lead to further investigations, even if they turn out not to be supported by the data.

    • SC.8.N.1.5 Analyze the methods used to develop a scientific explanation as seen in different fields of science.

    • SC.8.N.1.6 Understand that scientific investigations involve the collection of relevant empirical evidence, the use of logical reasoning, and the application of imagination in devising hypotheses, predictions, explanations and models to make sense of the collected evidence.

  • SC.8.N.2 The Characteristics of Scientific Knowledge

    • A Scientific knowledge is based on empirical evidence, and is appropriate for understanding the natural world, but it provides only a limited understanding of the supernatural, aesthetic, or other ways of knowing, such as art, philosophy, or religion.

    • B Scientific knowledge is durable and robust, but open to change.

    • C Because science is based on empirical evidence it strives for objectivity, but as it is a human endeavor the processes, methods, and knowledge of science include subjectivity, as well as creativity and discovery.

    • SC.8.N.2.1 Distinguish between scientific and pseudoscientific ideas.

    • SC.8.N.2.2 Discuss what characterizes science and its methods.

  • SC.8.N.3 The terms that describe examples of scientific knowledge, for example; "theory," "law," "hypothesis," and "model" have very specific meanings and functions within science.

    • SC.8.N.3.1 Select models useful in relating the results of their own investigations.

    • SC.8.N.3.2 Explain why theories may be modified but are rarely discarded.

  • SC.8.N.4 As tomorrows citizens, students should be able to identify issues about which society could provide input, formulate scientifically investigable questions about those issues, construct investigations of their questions, collect and evaluate data from their investigations, and develop scientific recommendations based upon their findings.

    • SC.8.N.4.1 Explain that science is one of the processes that can be used to inform decision making at the community, state, national, and international levels.

    • SC.8.N.4.2 Explain how political, social, and economic concerns can affect science, and vice versa.

SC.8.P Physical Science

  • SC.8.P.8 Properties of Matter

    • A All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia.

    • B Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

    • SC.8.P.8.1 Explore the scientific theory of atoms (also known as atomic theory) by using models to explain the motion of particles in solids, liquids, and gases.

    • SC.8.P.8.2 Differentiate between weight and mass recognizing that weight is the amount of gravitational pull on an object and is distinct from, though proportional to, mass.

    • SC.8.P.8.3 Explore and describe the densities of various materials through measurement of their masses and volumes.

    • SC.8.P.8.4 Classify and compare substances on the basis of characteristic physical properties that can be demonstrated or measured; for example, density, thermal or electrical conductivity, solubility, magnetic properties, melting and boiling points, and know that these properties are independent of the amount of the sample.

    • SC.8.P.8.5 Recognize that there are a finite number of elements and that their atoms combine in a multitude of ways to produce compounds that make up all of the living and nonliving things that we encounter.

    • SC.8.P.8.6 Recognize that elements are grouped in the periodic table according to similarities of their properties.

    • SC.8.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).

    • SC.8.P.8.8 Identify basic examples of and compare and classify the properties of compounds, including acids, bases, and salts.

    • SC.8.P.8.9 Distinguish among mixtures (including solutions) and pure substances.

  • SC.8.P.9 Changes in Matter

    • A Matter can undergo a variety of changes.

    • B When matter is changed physically, generally no changes occur in the structure of the atoms or molecules composing the matter.

    • C When matter changes chemically, a rearrangement of bonds between the atoms occurs. This results in new substances with new properties.

    • SC.8.P.9.1 Explore the Law of Conservation of Mass by demonstrating and concluding that mass is conserved when substances undergo physical and chemical changes.

    • SC.8.P.9.2 Differentiate between physical changes and chemical changes.

    • SC.8.P.9.3 Investigate and describe how temperature influences chemical changes.
