Element Hunter


You have been reading in your book how Itch has been searching for and collecting elements for years. Each element has its own shoebox that Itch keeps in his shed. It's your turn to be element hunters!

You will have two elements for which you will hunt. It will be your responsibility to find your element or find a way to model where you can find your element. This (along with other information) will be placed in a tissue box. Here are some requirements for each box:

1. The inside of your tissue box must be lined with construction paper depending on the classification of (to which family) your element belongs.
      • alkali metals - light blue
      • alkaline earth metals - yellow
      • transition metals - red
      • rare earth metals - pink
      • other metals - brown
      • metalloids - green
      • halogens - orange
      • noble gases -dark blue
      • other non-metals - white
2. On the back of the inside of your box, you must include the element symbol, name, atomic number, and mass. The general format we will use is this:

3.  Included on a 3x5 index card that will be in a sleeve attached to the bottom of your box, you will need the following information:
      • who discovered the element in what year
      • phase at room temperature
      • melting point in degrees C
      • boiling point in degrees C
      • density
      • electronegativity on Pauling scale
      • atomic radius in pm
      • color
      • uses

You will be expected to use some of the book resources we have in class in conjunction with reliable websites. Here are some good ones:

http://www.periodictableontheweb.com/
http://www.ptable.com/

This will be an assignment you will work on as we continue through the unit. There will be periodic (pun intended) check-in points to see your progress then we will assemble our table once the project is complete. Our due date is April 20 but there will be other projects to work on between now and then, too, so be sure to budget your time and don't wait until the last minute.

HAPPY HUNTING!

Atomic Odyssey

apple pie history lady



"As American as apple pie." Is apple pie truly American? How did this tasty dessert originate?

Pie and the atom have both changed over the course of history. Read this brief article (http://content.time.com/time/nation/article/0,8599,1862315,00.html) on the history of pie and leave a comment about the thing you found most interesting in pie history.





This online WebQuest will lead you to multiple websites from which you can gather information to answer the questions that follow each link about the history of the atom. Further directions are on the website. Write the questions and all responses in your lab journal using complete sentences. Title this "Atomic Odyssey". It is due Friday, April 10.
