3. Collect sand and Gravel - The sand and gravel will be collected on the fittle paper, while the salt solution will pass through into the beaker step 4: Seperation of sand and Gravel (Sieving) 1. Sieve Again: - use a smaller meoh sieve to further seperate the sand from the gravel. 2. collect Fraction: - Collect and set aside the sand and gravel Step 5. Separation by Exaporation. 1. Evaporation. - Heat the saltwater solution to evaporate the water, leaving behind the salt crystals.
