Teacher Notes
These puzzles match common classroom science topics: the solar system, living things and habitats, the human body, and weather and simple experiments. A few ideas for using them:
- Warm-up: put one puzzle on the board at the start of a science lesson and let pupils solve it together.
- Vocabulary check: after teaching a topic, hand out its ten puzzles as a quick review — the clues double as definitions.
- Mixed ability: the shorter words (MOON, OCEAN, BRAIN) suit younger pupils, while the longer ones (AMPHIBIAN, DIGESTION, EVAPORATE) challenge older ones. Let pupils pick their level.
- No printing? The puzzles work just as well read aloud or shown on a screen.
