Tried of having students to tedious and time consuming timeline posters? Are those digital timeline tools just too much to figure out? Then this product is for you! I put together an activity that goes through all the major contributors to the atomic theory. (Democritus, Aristotle, The Alchemists, John Dalton, JJ Thomson, Ernest Rutherford, Bohr, Chadwick, and Schrodinger)
The first activity page has students work through a hands on modeling activity. Then students use websites, videos, and simulations in order to answer key questions about the contributors to the atomic theory. The final page of the document includes key vocabulary about atoms, elements, and compounds.
