About Science Crossword

Every Science crossword here is themed end to end, from the words to the challenge. Experiments, discoveries, and the scientific method. Kids meet words like atom, experiment and crystal as they solve, and that repeated, low-pressure exposure is exactly how new vocabulary sticks.

You'll find this Science crossword in three difficulty levels - easy (ages 4-6), medium (ages 7-9), and hard (ages 10+) - each free to print with its own answer key. Working through them builds vocabulary, spelling, and clue-based reasoning, and because every level shares the same theme, siblings of different ages can play side by side.
