From Stone Age tools to the Large Hadron Collider, there’s
always the potential for catastrophe when it comes to science.
And what better way to get your middle schoolers psyched about
scientific leaps than challenging them to avoid disaster? Each
chapter of the book describes a scientific breakthrough and the
consequent catastrophes associated with it. Experiments are
rated from Low (no risk of catastrophe) to High (involves the
use of fire, hot liquids, or hazardous substances, making adult
supervision required). Kids will love the hands-on experiments
and researcher parents will revel in preventing potential
calamity. The Book of Potentially Catastrophic Science: 50
experiments for daring young scientists by Sean Connolly $13.99
