STEM Challenge Cards Generator
Print hands-on build challenges for grades K–5. Each card pairs a goal (the tallest tower, a bridge that holds 10 pennies, a boat that floats 20 coins) with materials that suit it and a grade-level rule. Add an Ask–Imagine–Plan–Create–Test–Improve recording sheet and big labels for your materials bins.
Print the cards on card stock and keep each set with its materials bin. Children pick a card, build, and record their work on the recording sheet. The season theme changes only the wording of each challenge.
