Name of Experiment: Mixture Separation

Materials

• Canister filled with salt, sand, and iron filings
• Beakers
• Magnet
• Plastic bag
• Coffee filters
• Hot plate
• Triple beam balance
• Glass stirrer

Procedure:

1. Arrange materials
1. Find the mass of the substances in the canister and record it
2. Separate iron
1. Use the magnet in the plastic bag to attract the iron filings
2. Pull away the magnet inside the plastic bag to let the filings fall onto an empty coffee filter
3. Repeat to filter out sand and salt
4. Find the mass of the iron filings and record it
3. Separate sand
1. Add a small amount (about 50 mL) water to a beaker
2. Pour in the salt and sand mixture
3. Stir to dissolve salt
4. Strain through a coffee filter into another beaker to separate saltwater and sand
5. Allow salt to dry out
6. Find mass of sand and record it
4. Separate salt
