Pollution and the Environment Word Search, Scramble and Crossword Puzzle

I made this pollution and environment puzzle set for my Year 3 and Year 4 students during our Earth science unit. The kids had heard of pollution but couldn't name different types or explain simple solutions. So I put together a word search, a word scramble, and a crossword using words like pollution, air pollution, water pollution, land pollution, noise pollution, light pollution, microplastic, acid rain, runoff, smog, toxin, ozone, particulate, eutrophication, and bioaccumulation. Nothing fancy — just puzzles to help the vocabulary stick without making them feel hopeless.

The PDFs are six pages. Three puzzles, each with its own answer key page. The word search works well for quiet time after break. The scramble gets them talking because they argue about whether recycling really makes a difference. The crossword I use for partners. I added a couple simple rubbish bin and recycling symbol drawings but nothing too busy.

Works for Year 2 through Year 5. Print and go. Sometimes I have early finishers list three ways to reduce pollution at home on the back. The kids actually ask for these now.
