10/27/08: In this activity you are going to measure and record the density of the objects in your bin. You are going to need a ruler, knowledge of geometry (formulas for volume of each object), and a triple beam balance (you'll need to share).

Your first step, however, is to make a new page in this wikispace: click on "New Page" on the Action Bar to the left. Use you first name to name your page.

Here's an example of a data table:


 * ~ Object Description ||~ Mass (g) ||~ Volume (cm³) ||~ Density (g/cm³) || **Possible Materials** ||~ Comments ||
 * = Block #1 ||= 7.1 ||= 15.625 ||= .4544 || White Pine, Yellow Pine ||= [|Source 1] ||
 * = Block #2 ||= 11.3 ||= 15.625 ||= .7232 || Satin, Beech wood ||= [|Source 1] ||
 * = Block #3 ||= 8.6 ||= 15.625 ||= .5504 || Sycamore wood ||= [|Source 1] ||
 * = Block #4 ||= 19 ||= 15.625 ||= 1.216 || PVC ||= [|Source 4] ||
 * = Block #5 ||= 18.8 ||= 15.625 ||= 1.203 || PVC ||= [|Source 4] ||
