Why this book counts

  • General / Multiple Sciences
  • Maker / Problem-Solving
  • Story / Adventure

A run of inexplicably grumpy magical creatures gives Zoey and Sassafras a pattern to investigate before their summer deteriorates further. The mystery advances through observations, comparisons, research, and revised ideas, so inquiry is the route to the solution rather than an inserted lesson.

The science inside

  • General Science

Your child will meet:

  • Repeated observations can reveal a pattern that one isolated event would not show.
  • Comparing affected and unaffected cases can help narrow possible causes.
  • A hypothesis should change when new evidence does not fit the first explanation.

Use it this way

Keep a cause table with one row for each bad day, recording what changed, which creature was affected, and what remained the same; ask your child to revise a theory only when a new clue requires it.

Parent effort: Quick discussion

In the seventh book, Zoey and Sassafras are excited to enjoy their summer with their magical friends. But . . . why is everyone so grumpy? A bunch of bad days one after the other lead Zoey to suspect that something more is afoot. It's up to Zoey and Sassafras to solve the mystery before they end up with one bummer of a summer! Each story in the Zoey and Sassafras series features a new magical animal with a problem that must be solved using science. There isn't a set formula for each book; Zoey sometimes needs to run experiments, while other times she needs to investigate a mystery, and yet other times she needs to do research. Zoey models how to keep a science journal through her handwritten entries in each story. Each story is complete with a glossary of the kid-friendly definitions for scientific terms used. The series highlights child-led inquiry science and the topics covered align with both Common Core and Next Generation Science Standards.
