GATHERING DATA ABOUT THE ELEMENTS

First:  Let's get some data on those elements so we can see how to organize it ourselves.  Then we'll check later with "experts" to see how well we did.

    Since there only were about 60 known elements during the time the periodic table was being developed and that was the experts starting point, that is the starting point for where we will start to investigate and gather data.

    Unfortunately, we do not have the luxury having all those elements in the classroom to study and gather information on directly.  However, we can study them "at a distance"  and gather data from the Internet about them.

    Find your group number and that will be your elements to collect data.  Your data should included information that would relate to its ultimate position in the periodic table and why the symbol was given to that element.  Since we will be constructing a periodic table in the classroom and space on the element cards will be limited, only 5 different data "bytes" will be accepted per element.  Your group will need to decide what those five data "bytes" will be and remember what technology was available at that time.  If the information used was a characteristic which could not be described for the time period of Mendeleev (1869), the data "byte" will be discarded.  If all five pieces of information are discarded, this will result point deduction for accuracy of element information.

    Use the search engines listed and other websites.  Submit a website evaluation form for each reference used.  If the website is rejected by the instructor as an invalid source of information, more must be used.  If discrepancies in information exist, examine the websites more closely for validity.

    Once finished, your group needs to be prepared to defend the information put on the index cards to be presented during the class discussion that will follow this part of the project.


GROUP ONE:  hydrogen, carbon, silicon, arsenic, selenium, zinc, cadmium, iodine, calcium, thorium.

GROUP TWO:  beryllium, nickel, zirconium, platinum, osmium, sodium, tantalum, bromine, antimony, titanium.

GROUP THREE:  fluorine, nitrogen, phosphorus, rubidium, bismuth, vanadium, cobalt, silver, barium, indium.

GROUP FOUR:  lithium, magnesium, palladium, chromium, tungsten, mercury, thallium, sulfur, niobium, lead.

GROUP FIVE:  uranium, tin, copper, boron, iridium, ruthenium, manganese, cerium, potassium, molybdenum.

GROUP SIX:  tellurium, iron, chlorine, aluminum, oxygen, strontium, lanthanum, cesium, gold, rhodium.

    Gathered data needs to be put in a file using the notepad function (found in program ->accessories of the start up key).  Store data as a separate file on a floppy disk given to your group for data gathering.  "Cut and paste" the URL used for the source into each file for each element researched and type into that file whatever information was obtained from that URL.  Save this data for each element separately on the disk.  The sources will be needed as references for the final book product bibliography.   Use, at least three different sources, since in a lab the results of various tests would be repeated at least this many times, to make it "statistically valid".

Here are some suggested websites; however, don't feel limited to these sites.  These are just a starting point:

The Comic Book Periodic Table

Chemical Elements.com

Web Elements Periodic Table

Element Database

These search engines may prove helpful; however, don't feel limited to these sites.  These are just a starting point:
