Using Webelements
What I had actually meant was for you to use the webelements periodic table to identify all of the elements which are radioactive or synthetic (in which case they are radioactive). With the information that is provided from that site (discoverer or developer and the year in which this occurred), create a timeline of those elements - paying particular attention to whether these cluster around a certain period or years, if there were individuals who participated in more than one discovery/development or if it all appears to be pretty random. When you get this list finished, create a word document with the timeline and turn it in to me. I'll be curious to see what you discover.

Evidently, you haven't had time to get any work done on the last assignment - a timeline on the discovery/creation of radioactive elements. You will need to keep up with the websites you use to create the timeline. I will need to see a comment indicating how far you have gotten on this assignment by Thursday (3/20).
I asked for something from you by 3/20 - today is 4/1. Do you have something to submit? If not, we need to have a serious conversation.
Your final project will be determined by the amount of work you have completed as of now. If I don't hear from you by the end of the week, I will reassign you to another project.
Please contact me - either through the blog or in person.
