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.
