Density

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).

Procedure

 * 1) 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.
 * 2) Create (or copy) the data table below to store your data. Place this table in your page.
 * 3) Take measurements of the objects in your bin and store the data in your table on your page.
 * 4) Calculate densities of the objects in your bin and store this in the table.
 * 5) Add a column to your table. Include a heading called, "Possible Material." Make a hypothesis about what material each object is made of (based on appearance, touch, color, hardness, smell, and any other observable characteristics) and write your hypotheses in the table.
 * 6) Research/Look up the densities of different materials. When you find a website that has information you want to use, you must reference it. Place a link to your references on your page or in the table. How you do this is up to you, but if you use more than one reference be sure to indicate where you use each reference.
 * 7) Compare known densities with your data and infer the material of each object. Change or confirm the "Possible Material" entries in your table.

Here's an example of a data table:
