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) ||~ Comments || **Possible Materials** ||
 * = Block #1 ||= 6.3 ||= 15.625 ||= 0.40 ||=  || Alder Wood ||
 * = Block #2 ||= 12.3 ||= 15.625 ||= 0.8 ||=  || Apple Wood ||
 * = Block #3 ||= 7.7 ||= 15.625 ||= 0.5 ||=  || Alder Wood ||
 * = Block #4 ||= 18.7 ||= 15.625 ||= 1.2 ||=  || Plastic ||
 * = Block #5 ||= 16.9 ||= 15.625 ||= 1.1 ||=  ||   ||
 * = Block #6 ||= 142.7 ||= 15.625 ||= 9.4 ||=  || Metal ||
 * = Block #7 ||= 43.7 ||= 15.625 ||= 2.8 ||=  || Metal ||
 * = Block #8 ||= 127.1 ||= 15.625 ||= 8.1 ||=  || Metal ||
 * = Block #9 ||= 22.2 ||= 15.625 ||= 1.4 ||=  || Plastic ||
 * = Block #10 ||= 137.2 ||= 15.625 ||= 8.8 ||=  || Metal ||
 * = Small Wood Ball ||= 5.8 ||= 28.3 ||= .2 ||=  || Wood ||
 * = Medium Wood Ball ||= 19.5 ||= 100.5 ||= .2 ||=  || Wood ||
 * = Large Wood Ball ||= 48.2 ||= 211.3 ||= .2 ||=  || Wood ||
 * = Super Ball ||= 39.2 ||= 157 ||= .2 ||=  || Rubber ||
 * = Golf Ball ||= 45.8 ||= 127.2 ||= .4 ||=  || Plastic and Rubber ||
 * = Silver Colored Cylinder ||= 15 ||= 5.3 ||= 2.8 ||=  || Metal ||
 * = Long Plastic Cylinder ||= 15.5 ||= 12.7 ||= 1.2 ||=  || Plastic ||
 * = Small Gold-Colored Cylinder ||= 57.4 ||= 3.9 ||= 14.8 ||=  || Metal ||
 * = Blue Cylinder ||= 14.9 ||= 8.5 ||= 1.8 ||=  || Plastic ||
 * = (other - fill in yourself) ||=  ||=   ||=   ||=   ||   ||
