Thickness of Aluminum Foil

Thickness of Aluminum Foil

• Mr. Strickland, Science Instructor

2
Objective

• In this lab, we will practice collecting data,
  measuring, and organizing information.
• We will also utilize mathematical formulas to
  determine the thickness of a piece of aluminum
  foil.

3
Materials

• Aluminum Foil (2 brands)
• Balance
• Ruler
• Scissors
• Calculator

4
Procedure

• 1. Using the scissors and the ruler, cut a
  rectangular piece of aluminum foil.
• 2. Determine the area of the piece of foil.
• ( A l x w _____ cm2)
• 3. Using the balance, determine the mass of the
  aluminum foil. For best results, ball the foil
  up before putting it on the balance.
• 4. Repeat the procedure for the other brand.

5
Analysis(You do NOT have to write the
questions!)

• Using the density of aluminum, calculate the
  volume of each piece of aluminum foil.
• density of aluminum 2.699 g/cm3
• Density Mass / Volume, so Volume Mass /
  Density

6
Analysis (cont.) (You do NOT have to write the
questions!)

• 2. Using the formula for volume of a rectangle,
  calculate the thickness (or height) of each piece
  of aluminum foil.
• Volume length x width x height, so
• Height volume / (length x width)
• 3. Convert the thickness of each brand to meters
  (m), kilometers (km), and millimeters (mm).
• 4. Which brand is the thickest?

Summary

• Write one paragraph describing the objective of
  the lab, the materials used, a summary of the
  procedure, and an explanation of the results.
