By Dr. Miriam Douglass, Dr. Martin McClinton
Learners convert units used to designate pressure. Units for pressure are atm, mm Hg, torr, and pascal.
By Eileen Bouchard
Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.
