Charlotte the Scientist is Squished by Camille Andros illustrated by Brianne Farley*

Charlotte loves science.  She seizes any opportunity she has to apply the scientific method.  Her main problem, however, is her large family!  She has no space  to perform her experiments.  So she applies the scientific method to this personal problem and soon realizes she needs a new conclusion!
Perfect for introducing the scientific method to younger students.
*Highly recommend.
