Glencoe Chapter 4 Resources
Glimpses of Atomic Theory Through Time This site gives some history in the concept development of the atom—everything from Aristotle to nanotechnology. There is a conventional photo of an oil droplet and an optical image showing features 1-nm across (approximately 5 atoms in width). Compare and contrast the two images in your Science Journal.	The Rutherford Gold Foil Experiment Rutherford discovered that the atom was mostly empty space. Visit this Web site and try out the gold foil experiment simulator. Increase the size of the opening in the lead screen and watch the affect it has on the particles.
Millikan’s Oil Drop Experiment Visit this site to learn more about Robert Millikan’s oil drop experiment. Try the simulation of Millikan’s chamber. Adjust the voltage and watch the drops. Do you see any suspended in air? Read on to find out why these drops stop mid-air.	Henry (Harry) Gwyn Jeffreys Moseley’s Contribution to Atomic Structure Visit this site and discover the contributions that Moseley made to atomic structure. Read the article and find out what happened to this great scientist at a very early age.
