How to separate Sand, wood shaving, iron filings and salt from a mixture?
stir with a magnet to pick up iron filings
pour the rest into water -- wood floats, sand sinks
skim off the wood, evaporate the water.
To separate sand, wood shavings, iron filings, and salt from a mixture, you can follow these steps:
1. Use a magnet to separate the iron filings: Move a magnet over the mixture to attract the iron filings. The magnet will attract the iron filings, allowing you to collect them separately.
2. Dissolve the salt in water: Pour the mixture into a container of water and stir it thoroughly. The salt will dissolve in the water, making it separate from the sand and wood shavings.
3. Filter the mixture: Set up a funnel with a filter paper or coffee filter, and place it over a receiving container. Slowly pour the mixture through the filter. The sand and wood shavings will be trapped in the filter paper, while the saltwater solution (made in the previous step) will pass through and collect in the receiving container.
4. Collect the sand and wood shavings: Rinse the sand and wood shavings remaining on the filter paper with water to remove any remaining salt. Once rinsed, leave them to dry, and then separate the sand and wood shavings into separate containers.
Now you have successfully separated the sand, wood shavings, iron filings, and salt from the original mixture.
