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:
