New Lab and Learning Excel

During a lab that we started yesterday and finished today, we had 567 small square pieces of paper or "atoms" that was plain on one side and colored on the other. In this lab we put all of the squares in a cup and mixed them up. After mixing them up we separated the color squares from the plain squares. After separating them we counted the white squares or (radioactive atoms) back in the cup and removed the colored ones (decayed atoms) We did this six times. What this did was taught us about half life. Here is a link that explains what half life is. After the completion of the lab we had to graph the data in excel. Most of us have never used excel before but still we were able to understand it pretty fast.
