Overview

A mixture contains two or more substances that retain all their original properties and can be physically separated. Mixtures can be homogenous or heterogeneous.

The classroom resource provides a video that will describe the two types of mixtures. There is also a short test that can be used to assess students' understanding.

    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.
