Being Mendeleev

You will research certain elements and display your results on tiles that mimic the blocks on a modern periodic table. However, they will contain more data because you and your classmates will investigate various organizations of the elements in a manner similar to Mendeleev and Meyer.

Being Mendeleev
Learning about the structure of the Periodic Table by mimicking the building of the original.

Web Worksheet locatation
• http://poster.4teachers.org/ (note that there is NOT www) In the right column change the drop down menu from "poster ID" to "worksheet ID type in 123828. At the next screen, click on the number.
• additional resources at http://trackstar.4teachers.org, type in 282870 in the "find a track" area. This site is also linked on the worksheet.

General Instructions
• Read all instructions carefully.
• Be sure you include all requested materials.
• Neatness and grammar count.
• Creativity helps.
• There are a lot of interesting websites, but get your work done first and then go back to check out the cool stuff.

This is the minimum information required for each element:
1. Name
2. Modern symbol
3. Atomic number
4. Atomic Mass
5. Number of protons
6. Number of neutrons
7. Solid, liquid, or gas at room temperature
8. Melting point and boiling point
9. Major category: metal, non-metal, transition element, inert gas, metalloid

Pick and research at least 5 from this list that you think might help organization of the table.
• Name origin
• Is there an ancient (picture) or alchemist's symbol? If so, what is it and what did it mean?
• Does it have a characteristic color, taste or smell?
• Does it react easily with other elements or compounds?
• Is it a metal, metalloid or nonmetal?
• When was it discovered?
• Where was it discovered?
• Who was the discoverer of your element?
• Name of country of discoverer.
• When was it first used? What was its original use?
• The elements relationship to humans and the environment (dangerous or helpful?)
• Can the element or compounds made from it be recycled? If so, how and where? Is it done in your community?
• What do humans make with your element? (List at least 3 things.)
• Is the disposal of your element an environmental concern? Are there special disposal needs? Explain.
• Where do humans normally find your element?
• How do they process it to purify it for use from its natural state?
• If it is normally a mineral or an ore in nature, what are the names of its most common ores or minerals?
• What country is its biggest producer?
• Does it have any impact on history or civilization?
• How much is your element worth?
• Is your element poisonous to plants, animals or humans?
• Is it a nutrient?
• Can it be used in place of another element?
• Could it be replaced in its use by another substance?
• Is it commonly mixed with another substance that makes it more valuable to humans?
• Names of the elements in 6 different countries.
• What is the most interesting thing that you learned about your element?

Element data and tile

Each of you will be assigned three elements in a random drawing. It will be your job to search for the listed information then create a table block (or tile) for each one.

Collect all information in your log books before creating any tiles. An example will be provided. Please use the example as your template. It will make the organization much easier! Your tiles must contain at least each of the following items.
o The name, symbol, atomic number, number of neutrons, and atomic mass of your element.
o The physical properties of the element.
o Is it a solid, liquid or gas at room temperature?
o Physical properties & category.
o Any other information that will help organization of the elements.
