About

This quiz focuses on the CER (Claim, Evidence, Reasoning) framework, a fundamental scientific writing and argumentation structure used across middle school science curricula. Based on the complexity and application of concepts presented, this material is appropriate for grades 6-8, where students are developing critical thinking and scientific communication skills. The questions assess students' ability to distinguish between the three components of scientific argumentation: claims (statements that answer a question or solve a problem), evidence (data and observations that support the claim), and reasoning (explanations that connect evidence to claims using scientific principles). Students need to understand that effective scientific arguments require all three elements working together, and they must be able to identify each component within both controlled examples and real-world scenarios involving topics like plant growth, matter, plate tectonics, and data analysis. Created by Francis Jequinto, a Science teacher in US who teaches grade 6-8. This comprehensive assessment tool serves multiple instructional purposes throughout the learning process, functioning effectively as a diagnostic pre-assessment to gauge prior knowledge, a guided practice activity during initial instruction, or a formative assessment to check understanding before moving to more complex argumentation tasks. Teachers can deploy this quiz as a warm-up activity to activate student thinking about scientific writing, assign it as homework to reinforce classroom learning, or use it as a review tool before summative assessments. The quiz aligns with Next Generation Science Standards practices, particularly those emphasizing scientific argumentation and evidence-based reasoning (NGSS Practice 7: Engaging in Argument from Evidence), and supports Common Core literacy standards in science (RST.6-8.8: Distinguishing among facts, reasoned judgment based on research findings, and speculation). This resource strengthens students' ability to construct coherent scientific explanations and prepares them for more sophisticated research and laboratory report writing.

Which of the following includes reasoning?

We took two pictures. One had yellow leaves and the one on the windowsill had green leaves.

Our plant on the windowsill grew more and was green. I know that plants need sunlight to grow, so the green color might have something to do with getting the light they need.

Our plant in the closet is yellow. The plant on the window sill is growing. They are different colors.
