In this experiment, students will determine the mass and volume of various objects to calculate the densities of those objects.
|Density Sample, Metal Cylinder||JE-105A-D73-7||1 per table|
|Graduated Cylinders (100mL)||JE-105A-S81||1 per table|
|Balance, Scale, Digital 1500g||JE-105A-S123,123a, 130||1 per table|
|Calipers, Digital - Battery||JE-105A-D87-S121||1 per table|
|Density Sample, Lead Sinker||JE-105A-X32||1 per table|
|Towels, Paper||JE-Labs Under Sinks||1 per table|
|Mass, Hooked, 1 kg Giant Pink Foam||JE105A-X shelves top||1 per room|
|Density Sample, metal sinker||JE-105A-D73-5||1 per table|
The cylinder specified as wood can be any material that floats having a density not too close to 1 g/cc, and it must easily fit inside the graduated cylinder. Find out whether the instructor wants to use the dual pan or the digital balances, or the dial or digital calipers. (Prof. Dolan uses unusually shaped objects with at least a 5 ml volume in place of the wooden cylinders, and wants only digital balances and digital calipers. The metal cylinders for Prof. Dolan should not have hooks, and because that makes for more water spillage, the tables should each have a large piece of paper towel. Lead sinker is #2 or bigger, but must fit easily into graduated cylinder.)
Along with the initial apparatus set-up, supply a sufficient number of the appropriate paper procedure handouts for all of the lab sections that will use the set-up over the course of the week. Print the PDF, duplicate to double-sided pages, staple, and leave pile on instructor's table prior to first use of set-up.
