Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...

Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...
