Sections 4 & 5: Tonight you're going to mess around with a simulation of Rutherford's gold foil experiment. The link to the simulation is below (you may have to allow pop-ups for it to work):

There are two tabs (Rutherford and Plum Pudding), as well as several settings (energy, number of protons, etc). For each tab you will play around with the settings and make some observations. Remember that you can only draw accurate conclusions if you change only one variable at a time. For each tab, fill out a chart in your notebook that looks like this (you should have at least 3 rows of observations for each):

Variable changed	Observation	Possible explanation of the result

Section 5: You will be creating a color-coded periodic table with a detailed legend. You should use your textbook or ptable.com to color code all of the groups of elements listed below (pgs. 140-141 are particularly helpful for this). Then, make a legend on the back, which includes the name of the group, the color assigned to it and an explanation of that groups common properties and characteristics (use your textbook for this as well).

Groups:

Alkali Metals

Alkaline Earth Metals

Transition Metals

Post- Transition Metals

Metalloids

Noble Gases

Halogens

Other Non-Metals

Lanthanoids

Actinoids
