Properties of Matter Word Search, Scramble and Crossword Puzzle

I made this properties of matter puzzle set for my Grade 3 and 4 students during our physical science unit. The kids could describe an object as big or heavy but didn't know words like density, texture, or conductivity. So I put together a word search, a word scramble, and a crossword using words like odour, ductility, magnetism, malleability, solubility, hardness, conductivity, lustre, density, viscosity, boiling point, melting point, elasticity, toxicity, and flammability. Nothing fancy — just puzzles to help the vocabulary stick.

The download is six pages. Three puzzles plus an answer key page for each. The word search works well for quiet time after recess. The scramble gets them talking because they argue about whether a rock floats or sinks and why. The crossword I use for partners. I added a couple simple magnifying glass and scale drawings but nothing too busy.

Works for Grades 2 through 5. Print and go. Sometimes I have early finishers pick one object in the room and list three of its properties on the back. The kids actually ask for these now.
