Viac o knihe

Acadia Greene wants answers. What happened to the frogs she usedto see at her favorite local pond? Why do leaves change color in the fall, andwhy don't evergreen needles do the same? What is the water cycle, and what istranspiration? How do time zones work, and why does the sun set at differenttimes in different places within a single zone? How do germs infect us? Acadiadoesn't mean to do science, but shehas questions and her parents refuse to simply give her the answers. "Conductan experiment," they tell her. "Use the scientific method." So Acadia makeshypotheses, designs experiments, analyzes data, and draws conclusions. Acadiadoes science.
