Chemistry Crossword Puzzle with Word Search

Chemistry Vocabulary word search, scramble and crossword puzzle

I made this chemistry vocabulary puzzle set for my Grade 4 students during our matter unit. The kids had heard of atoms and elements but got lost when I introduced molecules, compounds, or the periodic table. So I put together a word search, a word scramble, and a crossword using words like atom, molecule, element, compound, mixture, reaction, reactant, product, acid, base, salt, ion, cation, anion, and pH. Nothing fancy — just puzzles to help the vocabulary finally click.

The PDFs are six pages. Three puzzles, each with its own 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 element or a compound. The crossword I use for partners. I added a couple simple beaker and molecule dot drawings but nothing too busy.

Works for Grades 4–5. Print and go. Sometimes I have early finishers write one difference between an element and a compound on the back. The kids actually ask for these now.
