That's the time period it takes a certain type of substance to decay and decrease by half.
To help tie the lesson in with a lab we used M&Ms as an example. Starting with 100 separate pieces we put them in a cup and shook them for ten seconds, then pour them onto a plate and remove all the ones with the labeled side 'm' up. we kept doing that for ten seconds 6 times collecting the data on a chart. Then in the packet we filled out all the questions and made a line graph on our data.
of course after we were done with the lab we got to eat the M&Ms!!
**dont forget to finish up pages 31 and 32 in the packet for homework!!**
and finally...CONGRATS TO THE GIANTS :)
