Mixture Separation

Virtual Lab

To Begin…

Read the entire lab sheet before continuing with this virtual lab so that you will be familiar with the procedures and concepts used. The following slides take you step-by-step through the procedure.

Step 1:

Samples of sand, salt, iron filings, and poppy seeds were given to the students.

Sand

Iron Filings

Salt

Poppy Seeds

Step 1:Response to a magnet (be sure to write your observations on your

data table):

Sand

Iron Filings

Salt

Poppy Seeds

Step 1:Behavior in water (solubility and floating):

Sand

Iron Filings

Salt

Poppy Seeds

Step 2:

You should develop a step-by-step procedure that anyone could follow that will separate a mixture of salt, sand, iron filings, and poppy seeds. This mixture is shown below.

Step 2:

Be sure to list the steps clearly for your procedure in a numbered list. You will need to use the knowledge you gained in step one of the lab to figure out a way for the mixture to be separated.

Step 3:

The following slides show the mixture being separated using lab techniques from step 1. The pictures are not labeled and are provided to guide your thoughts as you write your procedure.

Blow Torch

Salt water from filtration.

Separated sand

Separated poppyseeds

Separated salt

Separated iron filings

That’s It!!!

Be sure that your data table is complete. Answer the conclusion questions and turn your lab in by the date your teacher specifies. Good luck!
