Separating Solids
Submitted by: Jennifer G.
Recommended Grade Level(s):
Appropriate for: Grade 9
Teaching Topics & Concepts:
Integrated Chemistry and Physics, Filtration, physical properties
Materials:
• Mixture (in baggie)
• Sieve cups
• Small cups (4)
• Magnet (in baggie)
• Piece of Paper
Background Information:
For the first component of this lab, students receive a bag filled with pebbles, sand, chalk, and iron filings. Students then use a
magnet and sieve cups to separate the different parts of the mixture (see first 2 pages of attached lab).
For the second component of this lab, students receive a mixture of sand and salt (they take the initial mass) and must separate
the insoluble sand from the soluble salt with warm water. Students then check on their sand and salt cups each day until fully dry,
where they take the masses again to find percent composition of the sand and the salt.
