1. Sieving:
- Use a sieve with a mesh size that allows sand and sawdust to pass through while retaining iron filings and sugar.
- Pour the mixture into the sieve and shake it gently.
- The sand and sawdust will pass through the sieve, while the iron filings and sugar will remain on top.
2. Magnetic Separation:
- Use a magnet to separate iron filings from the remaining mixture.
- Move the magnet close to the mixture, and the iron filings will be attracted to it.
- Carefully remove the iron filings with the magnet.
3. Dissolving and Filtration:
- Dissolve the sugar in water.
- Stir the mixture until the sugar is completely dissolved.
- Filter the solution using filter paper or a coffee filter.
- The sand and sawdust will be retained on the filter, while the sugar solution will pass through.
4. Evaporation:
- Collect the sugar solution from the filtration process.
- Place the solution in a shallow dish and let it sit in a warm, dry place.
- The water will evaporate, leaving behind the sugar crystals.
5. Final Separation:
- After evaporation, you will have sand and sawdust on the filter paper and sugar crystals in the dish.
- Spread out the sand and sawdust mixture on a flat surface and let it dry completely.
- You can separate any remaining sawdust from the sand by gently blowing air over the mixture.
By following these steps, you can successfully separate the mixture of sand, sawdust, iron filings, and sugar.
