Substance Properties

5th Grade

Substances can be identified based on their properties and reactions happen when substances are combined.

• Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered.

• Make observations and/or measurements to produce data to seve as the basis for evidence for an explanation of a phenomenon or test a design solution.

• Make predictions about what would happen if a variable changes.

• Construct an explanation of observed relationships (e.g., the distribution of plants in the back yard).

• Use evidence (e.g., measurements, observations, patterns) to construct or support an explanation or design a solution to a problem.

• Identify the evidence that supports particular points in an explanation.

• Read and comprehend grade appropriate complex texts and/or other reliable media to summarize and obtain scientific and technical ideas and describe how they are supported by evidence.

• Compare and/or combine across complex texts and/or other reliable media to support the engagement in other scientific and/or engineering practices.

• Combine information in written text with that contained in corresponding tables, diagrams, and/or charts to support the engagement in other scientific and/or engineering practices.

• Communicate scientific and/or technical information orally and/or in written formats, including various forms of media as well as tables, diagrams, and charts.

• Students routinely identify and test causal relationships and use these relationships to explain change. They understand events that occur together with regularity might or might not signify a cause and effect relationship.

• Students identify similarities and differences in order to sort and classify natural objects and designed products. They identify patterns related to time, including simple rates of change and cycles, and to use these patterns to make predictions.

• Because matter exists as particles that are too small to see, matter is always conserved even if it seems to disappear. Measurements of a variety of observable properties can be used to identify particular materials.

• Chemical reactions that occur when substances are mixed can be identified by the emergence of substances with different properties; the total mass remains the same.
