The **worksheets** can be used in a number of ways, I used them in two ways, I laminated them both in the same pouch front to back for them to use as a mini whiteboard **and** write directly on them with a whiteboard pen then rub out the ink for reuse for different questions **and** classes **and** to use as work. Note If you have not looked at the **half**-**life** videos on the Radioactivity menu. is 13.6 counts per minute per gram, **and** the **half** **life** of **carbon**-14 is 5730 years. of thumb is that a radioactive **dating** method is good out to about 10 **half**-lives.

Cheeam **Half**-**Life** Problems #11 - 25 As a result, if my nehbor puts 120 ducks into my living room, the population would change like this: In the case above, the *half*-*life* of a duck is 1 hour because *half* the ducks would be dead in 1 hour. Problem #13 If you start with 5.32 x 10 9 atoms of Cs-137, how much time will pass before the amount remaining is 5.20 x 10 6 atoms? The *half*-*life* of Cs-137 is 30.17.
