Notice and Wonder: Comparing Three Cell Types
By Paul S.
A short, diagram-based worksheet for 8th graders that has students compare prokaryotic, animal, and plant cells through a Notice and Wonder table and a tree map classification. It builds close observation, scientific questioning, and categorization skills, and works well in a single 45-minute class period or as a station activity.
Customize for your classroom
Teacher Guide & Tips
- Introduce the three cell diagrams as a whole-class warm-up, then have students work individually or in pairs for about 15 minutes to fill in the Notice and Wonder table.
- Discussion question: What structures do you see in the plant cell that are missing from the animal cell, and why might that difference matter for how each cell works?
- Scaffold for struggling readers: Provide a word bank of organelle names (nucleus, cell wall, chloroplast, mitochondria, cell membrane, ribosomes) and a sentence starter such as "I notice that ___ is present in ___."
- Extension for advanced students: Ask them to write a wonder question comparing how prokaryotic and eukaryotic cells might have evolved differently, then use their tree map to justify a claim.
- Estimated time: About 45 minutes total, including roughly 15 minutes for observation, 15 for the tree map, and 15 for a brief class discussion.
