Students reinforce cell biology concepts by assembling image-based puzzles of animal and human cell diagrams. Learners piece together cell structures, building familiarity with organelles and cellular organization while practicing visual-spatial reasoning. This activity supports TEKS 7.12.D and 7.12.F (compare cell structures) and aligns with NGSS MS-LS1-2.
Skills: cell biology vocabulary, visual discrimination, spatial reasoning, scientific observation. Grades 6-10.
