Composting and Soil Health word search, scramble and crossword puzzle

I made this composting and soil health puzzle set for my 3rd and 4th graders during our Earth science unit. The kids could name a few things like worms and leaves, but they had no idea what words like compost, decompose, or soil meant when we started learning about how things break down and how soil stays healthy. So I put together a word search, a word scramble, and a crossword using words like compost, soil, worm, decomposer, moisture, air, carbon, nitrogen, leaf, fruit, vegetable, bin, and layer . Nothing fancy — just puzzles to help the vocabulary finally stick.

The PDF is four pages. Three puzzles plus one answer key page. The word search works well for quiet time after recess, and the scramble gets them talking because they argue about the spelling of "decompose" (it's a tricky one) or whether a worm and a mushroom are both decomposers (they are—they always have opinions about it). The crossword I use for partners, and I usually have a simple diagram of a compost bin with its layers nearby for the kids who need the visual support to see the process.

Works for 3rd through 5th grade. Print and go. Sometimes I have early finishers draw a compost bin and label its layers on the back. The kids actually ask for these now.
