• Ask questions about what would happen if a variable is changed.

• Ask questions that can be investigated and predict reasonable outcomes based on patterns such as cause and effect relationships.

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

• Analyze and interpret data to make sense of phenomena, using logical reasoning, mathematics, and/or computation.

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

• 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.
