Crystal Growing Experiment

To explore crystallization in a practical way, two different crystal-growing methods were used. One method uses borax, which produces faster and more defined crystals, while the second uses simple household materials so that anyone can try it at home.

Method 1: Borax Crystal Experiment ( advanced method)

Possible Outcomes:

Materials needed:

Very hot boiling water (safety hazard adult MUST be present when using this material
borax powder
clear jar or cup
spoon
pipe cleaner or string

Procedure:

pour hot water into a jar then add borax powder slowly while stirring until no more could dissolve. This created a saturated solution. Then take a pipe cleaner and shape it into a simple form ( such as a star or circle) and placed it into the solution, hanging in the middle of the jar make sure the pipe cleaner is not touching the jar on the sides or the bottom to give the crystals place to grow.

Then leave the jar undisturbed overnight. As the water cooled, borax particles should began forming solid crystal structures on the pipe cleaner.

Result:

Within several hours, visible crystals should be formed along the pipe cleaner, growing larger as time passed. The longer time it stays in the saturated solution undisturbed the better the outcome of the crystal.

Brief explanation:

As the hot water cooled, it could no longer hold all the dissolved borax. The extra particles bonded together in repeating patterns, forming crystals.

Method 2: Household Crystal Experiment ( simple method)

Materials needed:

warm water
salt or sugar
clear glass or jar
spoon
stick or string

Procedure:

pour warm water into a container and add salt or sugar slowly while stirring until the solution becomes saturated. The container is then left in a quiet place for several days. As water slowly evaporated, crystals began forming at the bottom and sides of the container.

Result:

Small crystals should appear after one or two days and continued growing over time.

Brief explanation:

When water evaporates, the dissolved particles are forced out of the solution and attach to each other, forming crystal structures.

Both experiments demonstrate the same scientific process:

when a saturated solution changes (by cooling or evaporation), particles arrange into solid crystal patterns. This is the same process that forms many natural crystals underground.
