MATERIALS: metric measuring spoons, 2 beakers, 2 spoons, 2 plastic cups, 15 mL table salt, 15 mL Epsom salts, 60 mL water, graduated cylinder, 2 pie plates, 1 sheet black paper, scissors PROCEDURE 1. Cut sheets of paper so that they fit inside the pie plates. Place one sheet in each pie plate. 2. Add the table salt to 30 mL of water in the beaker. Stir the water until the salt has dissolved. 3. Pour enough salt solution into one of the pie plates to completely cover the paper with a small film of liquid. Be careful not to pour into the plate any undissolved salt that may be in the bottom of the beaker. 4. Repeat steps 2 and 3 with the Epsom salts. Let the plates dry overnight. WHAT DO YOU THINK? Compare and describe the shapes of the crystals.   What do you think accounts for any differences you observe?   CHALLENGE Why are the shapes of the crystals the same as or different from the shapes in the materials you started with?
