Atoms and Molecules word search, scramble and crossword puzzle

I made this atoms and molecules puzzle set for my 4th graders during our chemistry unit. The kids had heard the words but thought atoms were like tiny dots and had no idea how they stick together to make molecules. So I put together a word search, a word scramble, and a crossword using words like atom, molecule, proton, neutron, electron, nucleus, element, compound, bond, water, oxygen, hydrogen, carbon dioxide, and periodic table. Nothing fancy — just puzzles to help the vocabulary finally make sense.

The PDF is four pages. Three puzzles plus one answer key page. The word search works well for quiet time after recess. The scramble gets them talking because they argue about whether water is an atom or a molecule. The crossword I use for partners. I added a couple simple circle and stick drawings showing atoms bonding but nothing too busy.

Works for 4th through 5th grade. Print and go. Sometimes I have early finishers draw a simple atom with protons, neutrons, and electrons on the back. The kids actually ask for these now.
