Acadia Greene wants answers. Who keeps stealing her blueberries just as they ripen on the bushes? Why is her hair curly? Why does the sun wake her up so early in the summer? Why does the tide submerge her sandcastles? How do rocks become sand? Acadia doesn't set out to do science, but she has these important questions and her scientist parents refuse to simply feed her the answers. "Conduct an experiment," they tell her. "Use the scientific method." So Acadia gathers evidence, makes hypotheses, designs experiments, uses the results to test her hypotheses, and draws conclusions. Acadia does science.

Acadia Files for autumn, winter, and spring will follow on future lists.

The author, Katie Coppens writes a recurring column for NSTA's middle school magazine Science Scope on science and literacy called The Integrated Classroom.
