How Do You Make Copper Sulfate Crystals?
Growing copper sulfate crystals is a popular and fun science experiment involving household items. Copper sulfate is available at chemistry and art supply retailers. The crystals develop as the water in the solution evaporates and forces copper sulfate molecules to bind together differently than they had before being dissolved in water: in a bright blue crystalline structure. Making a project out of copper sulfate crystals help students to understand the relationship that molecules have to one another. Fill a glass jar with 0.5 cups of warm water. Stir in 2 to 2.5 tbsp. of copper sulfate. Allow the jar to rest overnight in an area where the temperature remains stable, such as in a cupboard or on a table away from sunlight. Pour the liquid contents of the jar into an empty container, being careful to leave the crystals that have formed at the bottom of the jar intact. Pick one large crystal from the bottom of the jar. Tie a nylon string around the biggest crystal at the bottom of the fi
