Take the dry mixture, and using the screen filter separate the gravel from the salt and powder. Put the gravel in the “g” cup and the salt and powder into the “p” cup when filtering. Add 50 mL water to the salt and powder in the “p” cup, and stir until salt dissolves. Put the paper filter into the funnel stand, and put the “s” cup below the funnel. Pour the new water mixture into the filter. The powder will remain in the filter, which you can put into the “p” cup. The salt solution will drain into the “s” cup below the funnel.
I was able to successfully separate all three materials into separately labeled cups.

• To dissolve more solute once the solution is saturated, heat up the solvent.
• The mass of a saturated solution is equal to the mass of the solvent (water) plus the mass of the solute (salt, sugar, etc.)
• To tell if a clear liquid is a solution, let it evaporate. If it is a solution, the solute will be left behind in crystal form.
• Draw a picture of a saturated solution in a bottle.
