Step 1:  Create a half-life graph for an isotope with a half-life of

• days
• years
• minutes

using the data matrix from yesterday.  You can get free graph paper, if you need it, from http://www.printfreegraphpaper.com/

Step 2:  Tell me the significance of this photo.

Step 3:  Tell me why radon is a problem. Include a parent that makes radon and a daughter product.  (Hint:  consider states of matter--solid, liquid, gas)

Step 4:  Pick one of the isotopes on this graphic and tell me what it is used for in society.

Step 5:  Explain how probability influences the multiple pathways found on the bottom of this chart.
