About This Board

Review middle school cell biology: cell theory, organelles, plant vs animal cells, membranes, and microscopes. Built for Grades 6-8. 25 ready-to-play clues, no prep needed. This is a Grades 6–8 Science review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Cell Theory, Organelles, Plant vs Animal, Membranes & Transport, Microscopes.
