Chemistry Lab: Radioactive Half-life Simulation

On Thursday we did a lab called Radioactive half-life simulation. In this lab we were given a hundred pennies and we had to put them into a cup and pour them out. the ones that flipped to the head side are decayed and the ones that are flipped to the tail side are still radioactive. We put all the head pennies, the decayed ones, to the side and took the tail pennies and put them into the cup again. We shook the cup and poured all the pennies out. We did this six times for three trials and while we were doing this we recorded the data on our paper. Today, Friday, we enetered the data in our google doc acount and we printed the table out. We also watched a video E=mc^2. And i learned that this equation means energy equals mass times the speed of light squared.
