Nia's Greenhouse Seed Mystery

Ages 6–8

When mystery seedlings sprout and a whole row of tomatoes starts to wilt, junior detective Nia uses leaf clues and pH strips to solve two garden puzzles before the summer fair.

Careful observation and simple science tools (not guessing) can solve real-world mysteries, and patience is rewarded with a satisfying reveal.

Nia loved mysteries almost as much as she loved plants. So when Nana Pearl found a tray of unlabeled seed packets in the greenhouse, she grabbed her brass magnifying glass at once. "Every seed has a story," she whispered. "Let's find theirs."

"Look!" said Miles, pointing at a corner bed outside. "The tomatoes on the left are all droopy, but the ones on the right look perfectly fine!" Nia tilted her head. Two mysteries in one morning. This was going to be a very good day.

"Maybe it's poison!" Miles said dramatically. "Or thirsty roots!" Nia shook her head. "We don't guess, we test." She pulled the garden journal from her pocket and wrote: MYSTERY ONE — Why is only the left row wilting?
