What would the penny weigh

This link will take you the presentation my group presented on what a penny would weigh if you were to pick it up of the sidewalk.

To reflect back on our presentation I would definitely say that more time could have been spent on it. The presentation really lacked any effort, we met one day and split up the work. We ended up having duplicated information which caused to really stumble through the presentation. Overall our presentation was not something that this caliber of students should be doing.

I believe for all the groups, even though there was a winner, non were up to par. More scientific research should have been done using the skills of the class to give more persuasive information.
