Book Chapter |
This lab is an inquiry activity if it is done before the discussion of how center of mass and balance are related. However, students should have an idea of what center of mass is before they start the lab. Students…

Chemical and Biological Weapons of Mass Destruction
Book Chapter |
Chemical warfare began in prehistoric times with the use of such weapons as poisoned arrows. However, World War I was the beginning of modern-day chemical warfare. The birth of biological warfare evolved during World…

Mass Extinction and Meteor Collisions With Earth
Book Chapter |
Paleontologists divide extinctions into two broad categories—background extinctions and mass extinctions. Background extinctions occur continuously while mass extinctions are unusual in that they involve very large…
