Lab 1B: Aluminum Foil Lab by Katie and Maya

Procedure: First we knew we could find the thickness of the tinfoil by using Density=mass/volume. We found the length and width of the tinfoil using a ruler and rounding to 3 significant figures (in cm). Then we found the mass of the tinfoil using a scale (mass found in grams), and found the density using the water displacement method.

The water displacement method is using a graduated cylinder to find the volume of an irregular object. The water was at first at 89.0 mL and after the tinfoil was submerged under the water, the water level rose to 90.0 mL. The difference in the water levels was 1 mL and so the volume of the tinfoil is 1 mL.


After finding the density, we used our knowledge of the relationship between volume, mass, and density to calculate the thickness of the tinfoil.
