Curious McCarthy, named after the famous scientist Marie Curie, has decided to become a scientist herself. Her first hypothesis: That her mischievous younger brother will get noticed before her proper oldest sister, Charlotte. Using footnotes filled with funny observations, Curious invites readers to read her observations about her first days at a new school with an old-fashioned teacher and her entertaining evenings at home with her six brothers and sisters. A fun experiment brings the science to life and a glossary and discussion and writing prompts provide reader support.
