Students measure the mass and volume of different cylinders and then calculate the density of each followed by a comparison to textbook values. The students will also find the weight of each object when completely submerged in water and compare this weight to the weight of the displaced water. Introduces density as well as providing background on buoyancy.
|Balance, Scale, Digital 1500g||JE-105A-S123,123a, 130||1 per table|
|Calipers, Digital - Battery||JE-105A-D87-S121||1 per table|
|Density Sample, Metal Cylinder||JE-105A-D73-7||2 per table|
|Graduated Cylinders (100mL)||JE-105A-S81||1 per table|
Place (2) different cylinders per table. Note that brass and copper are interchangeable and count as the same.
The Cylindrical masses have symbols on the bottom.
Aluminum - No Symbol
Iron/Steel - +
Brass - =
Copper - ^
Zinc - .
Make sure to use the Mitotoyu Digital Calipers, and check for batteries. There should already be digital pan balances at each table.
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.
