NAEP Framework
NAEP Statement:: P8.4a: Elements are a class of
substances composed of a single kind
of atom.
NAEP Statement:: P8.4b: Compounds are composed of two or more different elements.
NAEP Statement:: P8.4c: Each element and compound has physical and chemical properties, such as boiling point, density, color, and conductivity, which are independent of the amount of the sample.†

Society Knowledge:
Students know:
A molecule is formed when two or more atoms join together chemically.
A compound is a molecule that contains at least two different elements.
All compounds are molecules but not all molecules are compounds.
A mixture consists of two or more different elements and/or compounds physically intermingled.
A mixture can be separated into its components by physical means, and often retains many of the properties of its components.
A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.
A solution consists of a solute and a solvent. The solute is the substance that is dissolved in the solvent.
Synthetic materials are made by humans.
Synthetic materials can be derived from natural resources through chemical processes.
The effects of the production and use of synthetic materials have impacts on society. Skills:
Students are able to:
Articulate a statement that relates a given phenomenon to a scientific idea, including the differences among compounds, mixtures, and solutions.
Identify and use multiple valid and reliable sources of evidence to construct an explanation differentiating among compounds, mixtures, and solutions.
Use reasoning to connect the evidence and support an explanation of differences among compounds, mixtures, and solutions.
Identify and describe the phenomenon under investigation, which includes the differences among compounds, mixtures, and solutions.
Identify and describe the purpose of the investigation, which includes providing evidence of differences among compounds, mixtures, and solutions.
Collect and record data, according to the given investigation plan.
Evaluate the data to determine the differences between compounds, mixtures, and solutions.
Obtain information about synthetic materials from published, grade-level appropriate material from multiple sources.
Determine and describe whether the gathered information is relevant.
Use information to illustrate how synthetic materials are derived from natural resources.
Use information to illustrate how synthetic materials impact society. Understanding:
Students understand that:
Compounds, mixtures, and solutions can be differentiated from one another based on characteristics.
Synthetic materials come from natural resources.
Synthetic materials have an impact on society. AMSTI Resources:
