Elinor and her friends become plant detectives in this first Elinor Wonders Why picture book!

When Elinor and Olive check on their class plants before leaving school for the weekend, everything looks good. But when the friends get back on Monday, they discover one of the plants has grown in a zigzag - up, then to the side, then up again. Their teacher said most plants only grow up, toward the sun. So, what happened to this one? Could it have something to do with how Ari knocked into the table - and shook the plants - when practicing his backflips?

Science sleuths will love following the plant clues that grow right before their eyes!
