Which activity would provide the best opportunity for third-grade students to apply critical-thinking skills in science?

• A. Identifying problems in the way an experiment was carried out
• B. Memorizing a list of science facts
• C. Reading about science without hands-on work
• D. Copying data from a chart without analysis

Answer: (A)

Critical thinking in science means looking closely at how ideas are tested, evaluating evidence, and figuring out better ways to investigate. The activity that asks students to identify problems in how an experiment was carried out puts this into action: it requires them to examine the steps, notice missing controls or unclear procedures, and explain why these issues could affect results. Students must justify changes to improve fairness and reliability, which builds reasoning about cause and effect, comparison, and planning. In contrast, memorizing facts focuses on recall rather than applying ideas; reading about science without hands-on work keeps learning passive and doesn’t require evaluating methods; copying data without analysis ends up as replication without interpretation, so it doesn’t develop the necessary questioning and reasoning skills.
