Introduction
Objective
Use several different techniques to separate a mixture of aluminum, iron filings, sand and salt into separate parts. This
experience will help you be more aware of lab procedures, and provide you with an opportunity to write your very own
formal lab procedures.
Hypothesis
If given a sample of matter that is a mixture, then it can be separated by a physical means.

Lab Report
Results
Data / Observations: In this section you need to have the following:
Organize this material in a data table.
 Total mass of the sample started with.
 Mass of each of the components of the mixture AND Observations that were made during the
experiment.
 % composition for each component of the mixture
**Graph - For this lab make a PIE GRAPH of % COMPOSITION
Calculations (formula and example calculation)
In this section you need to show the equation, set-up and results for each equation used to get the above
data.
Here is an example for you to follow.
Formula:
% composition =
Calculation:
𝑚𝑎𝑠𝑠 𝑜𝑓 𝑠𝑎𝑙𝑡
𝑇𝑜𝑡𝑎𝑙 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑠𝑎𝑚𝑝𝑙𝑒
𝑥 100
12.4 𝑔 𝑠𝑎𝑙𝑡
% composition = 40.0 𝑔 𝑚𝑖𝑥𝑡𝑢𝑟𝑒 𝑥 100 = 31.0 %
