how to separate a mixture of sawdust and powdered salt.

  1. Dump the mixture into a beaker or other container filled with water and wait.
  2. The salt will dissolve into the water, while the sawdust will float on top.
  3. Using a spoon, scoop up the sawdust from the surface of the water.
  4. Now the only substance remaining in the water is the salt.
  5. Heat the water and wait for it all to evaporate. 
  6. The salt will remain in the beaker, because its melting point is higher than that of water.
  7. Now the substances are separate.
Hope that helped you!!!
Regards!!!
