Method
1. You are given a mixture of water, sand, salt, gravel and metal.
2. Use the magnet to remove the metal pieces from the mixture. Place the
removed metal into test tube 1
3. Place the filter paper into the funnel. Place the funnel into a test tube.
4. Slowly pour mixture into the funnel. You are lft with sand in the filter
paper and water in the test tube.
5. Pour the water back into the beaker.
6. Leave the funnel and filter paper in the beaker
7. You are left with salt water. Grab your teacher to start the Bunsen burner.
8. Boil the water with the Bunsen burner until the water is separated from
the salt. DO NOT TOUCH THE BEAKER.
9. You are left with only salt
Results:
Pure Substance
How did we separate it?
Conclusion
Separating mixtures is easy as long as you understand the properties of each
pure substance. To remove metal from our substance, we used
__________________. Sand, salt and water do not respond to magnets, so we need to
use another method. We used _____________________ _________________ to separate
gravel and sand from the salt water. Finally we were left with a
____________________ and ____________________ mixture. To separate this mixture we
used the Bunsen burner and a process called________________________. In this
experiment we found that to separate a mixture you need to understand the
properties of each ___________________ _________________.
Pure substance, filter paper, salt, evaporation, water, magnets, sand,
gravel.
