Density of Pennies

This past week my chemistry students completed the Density of Pennies lab.  The one that I used in very similar to this one found here.  We have been working on our first unit which was measurement.  This lab was to help students with the calculations and measurements involved in density.  In addition, I added in a significant figures component as my students struggle with this every year.  If you are looking for a good lab to start the year off with I think that this is a good one.  The hardest part if finding enough pennies (especially the ones pre 1982).

What are some your favorites Chemistry labs? 

Looking for some new science teaching resources? (Giveaway alert!)

Although I am already back in school, I know that some of you are just going back next week.  I am always filled with great enthusiasm at the begining of the year and love having new ideas to try with my students.  I am hoping that one of my products will help you out.  I am giving away a product from my store.  You can check out my stores here (I have a few).
