HUMAN DENSITY DUNK

One day in chemistry Mrs. Lee asked do you think we could take the mass of a Human. The class answered yes. So Friday in class we did a human density dunk. Before we actually did the experiment we started planning the week before. The supplies we need where a kiddy pool, a big garbage can, containers to collect the water, beakers, paper and pencil, and a shower curtain. We had everybody signed a paper saying the job they would be responsible for . We also came to the conclusion that we would have to transfer pounds to grams and that we would have to take the volume and mass of the garbage can filled with water to subtract from the water that came out. The jobs where: Recorders, Dunkies, Helpers, Collectors, Media, Set up, and Clean up. The recorders where the people that wrote down all the information and transferred pounds into grams (g). Dunkies where the people that actually got into the water. Helpers helped the dunkies into the pool so they wouldn't get hurt. Collectors collected the water that feel out of the garbage can when the dunkie got in so we could find the volume. Media where the people that took pictures and video of the experiment. Set-up where the people that got the kiddie pool set up and the garbage can filled with water. Clean-up was of course the people that clean up after the experiment. we did a boy and a girl from each of the 3 hour chemistry classes so when we plotted the data we had 6 points. Of course the boys had a higher density, but the thing we found to be strange was that the density of a human was close to the density of water. We came to the conclusion that the density of a human is so close to water because we're made of mostly water.http://wiki.answers.com/Q/What_is_the_average_density_of_the_human_body This is a website that explains more about how a humans density is close to water.
