Half Lives
Today we learned about half lives and how they work. I thought that actually half of the atom was just decaying, but its only the amount of time it takes for the atoms to decay into stability, so there is no loss of mass. To help show this concept, we began to work on a half live lab. In the lab you cut out 567 squares then put them in a cup, dump the squares, and any that are on the colored side have "decayed" and are removed.

Thank you Ian for sharing your misconception because I thought that too at first! Thanks for sharing your lab that helped demonstrate that too! Next time, you may want to include how the data was kept in your table so we know how you went through your experiment! Thank you again!
