MATTER

 * Background Information on Chemical vs Physical Changes at Chem4Kids
 * Try the Chemical vs Physical Change quiz at Quia (20 ques)
 * Record your scores for these activities in your notebook


 * The Size of Things -- Chemistry Unit 1 Worksheet 5

**ATOMIC MODEL** Dalton's Playhouse
 * Investigate what led Dalton to his model of the atom
 * Trace the development of early models of the atom

**Thomson's Model of the Atom**

 * Investigate the 1897 experiments performed by physicist J.J. Thomson that proved the existence of electrons
 * Watch an animation of these same experiments (click twice to start the animation)


 * Exploring Electric Charges**
 * Interactively explore some of the concepts you have learned about atomic structure.
 * Use the simulation Balloons and Static Electricity
 * More fun with Static Electricity


 * Discovery of the Nucleus**
