Aluminum Foil Lab – Procedure

Part 1 – Density

• make sure the aluminum “shot” is dry
• make sure you take care to read graduated cylinder
• graph of mass (y) vs volume (x) will give density (slope)
• OK to use spreasdsheet to graph and generate line
• more than three (3) trials required (more is better)

Part 2 – Thickness

• how will you use density for part 2?
• what measurements do you need to determine thickness?
• no water / glassware required

Aluminum Foil Lab – Processing

• format of calculations section
• sig figs – how to apply
• units – how to show

Homework

• Lab Calculations (LNB)
• density of each trial
• average density
• area of aluminum foil
• thicknes sof foil (only if you are clear on how to do so)
