Which activity best serves as an informal assessment during a plant life cycle unit?

• A. Administer a timed written test.
• B. Students compare growth of plants under sun and shade and discuss observations.
• C. Have students memorize terminology.
• D. Do a long lecture with no student interaction.

Answer: (B)

Informal assessment in a plant life cycle unit comes from watching students explore and talk about what they observe as they investigate. When students compare growth of plants grown in sun and shade and discuss their observations, you get real-time evidence of what they understand about how light affects plant growth. Their explanations, questions, and the way they connect measurements to outcomes show where their thinking is solid and where misconceptions are forming. This kind hands-on, collaborative inquiry lets you adjust instruction on the fly and supports deeper learning. A timed written test focuses on quick recall and is a formal measure rather than a live check of understanding. Memorizing terminology doesn’t show whether students can apply ideas to real observations. A long lecture with no student interaction provides no opportunity to gather evidence about students’ thinking or to gauge how they use data to reason about plant growth.
