Internal and External Structures

4th Grade

Living things have internal and external structures that help them survive in their environment.

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

• Identify scientific (testable) and non-scientific (nontestable) questions.

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

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

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

• 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.

• Compare and refine arguments based on an evaluation of the evidence presented.

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

• Use data to evaluate claims about cause and effect.

• 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.

• 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.

• Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.
