• 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.

• Collaboratively develop and/or revise a model based on evidence that shows the relationships among variables for frequent and regular occurring events.

• Develop and/or use models to describe and/or predict phenomena.

• Use a model to test cause and effect relationships or interactions concering the functioning of natural or designed system.

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

• Compare and contrast data collected by different groups in order to discuss similarities and differences in their findings.

• Analyze data to refine a problem statement or the design of a proposed object, tool, or process.

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

• Respectfuly provide and receive critiques from peers about a proposed procedure, explanation, or model by citing relevant evidence and posing specific questions.

• Construct and/or support an argument with evidence, data, and/or a model.

• 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.

• Obtain and combine information from books and/or other reliable media to explain phenomena or solutions to a design problem.

• Students understand that a system is a group of related parts that make up a whole and can carry out functions its individual parts cannot. They can also describe a system in terms of its components and their interactions.

• Matter cycles between the air and soil and among organisms as they live and die.

• When the environment changes some organisms survive and reproduce, some move to new locations, some move into transformed environment, and some die.
