How does a crystal form a crystal?

Answer 1

(For Steph. Who likes things that sparkle.)Step 1: Gather materials. You will need: a glass of warm water. A pencil, string, small garden stone, and table salt. Step 2: Tie the pencil to the string. Lay the pencil rim to rim across the glass. Then, tie the stone to the loose end of the string. Make sure the stone is submerged in the liquid. Step 3: Add the table salt. You should add about three shakes of salt. If the water is not filmy, then add more. Stir the water. Step 4: Leave the glass in a sunny place like a windowsill. Allow about 2 weeks for this to work. Step 5: It's been 2 weeks! If you have a decent sized jewel, and you want to add some color to your clear crystal, add some food coloring of your color choice.ENJOY!!

Answer 2

It really depends on what type of crystal garden you have. The most common ones for kid's lab experiments are salt based gardens. They generally involve making a supersaturated solution of saline. A little bit of bluing and some small bits of porous material such as sponge would be added. The water from the solution begins to evaporate and the blue particles can no longer be supported. The salt will no longer be able to stay in the solution so it will begin crystallizing around the blue particles.

Answer 3

I'm not sure how to approach this, but from what I read, crystals depend on a process called "nucleation" to grow.

That's what I remember. Rather limited, but I'm sure someone will elaborate.

a crystal is a natural thing that is called a nucleation and it does glow.because natural things always glow for example= a diamond is a natural thing

1. A mineral crystal grows during mineral formation as atoms are added to its surfaces, edges and corners, the types of atoms that are added depends on the crystals growing surrounding.

Answer 5

Growing salt or sugar crystals is easy, safe and the experience is enlightening.
Get a pot of water heated up until it is between steaming and boiling. Pour sugar or salt in until it cannot hold any more. You will see that the substance is gathering on the bottom of the pan and cannot be stirred in. Remove the pan from the heat and place a rod that can go across the top of the pan with strings on it that hang into the liquid. Let this sit and cool undisturbed. Moving it can ruin the crystals. When completed you can pull your rod up and you will have crystals on the strings. If you are using sugar add a few drops of food coloring and you have a passable candy. There are kits that you can buy and grow wilder crystals.

Answer 6

How do crystals form

and how do they grow?

Crystals start growing by a process called "nucleation". Nucleation can either start with the molecules themselves (we'll call this unassisted nucleation), or with the help of some solid matter already in the solution (we'll call this assisted nucleation). Unassisted nucleationWhen molecules of the "solute" (the stuff of which you want to grow crystals) are in solution, most of the time they see only solvent molecules around them. However, occasionally they see other solute molecules. If the compound is a solid when it is pure, there will be some attractive force between these solute molecules. Most of the time when these solute molecules meet they will stay together for a little while, but then other forces eventually pull them apart. Sometimes though, the two molecules stay together long enough to meet up with a third, and then a fourth (and fifth, etc.) solute molecule.

Most of the time when there are just a few molecules joined together, they break apart. However, once there becomes a certain number of solute molecules, a so-called "critical size" where the combined attractive forces between the solute molecules become stronger than the other forces in the solution which tend to disrupt the formation of these "aggregates". This when this "protocrystal" (a sort of pre-crystal) becomes a nucleation site. As this protocrystal floats around in solution, it encounters other solute molecules. These solute molecules feel the attractive force of the protocrystal and join in. That's how the crystal begins to grow.

It continues growing until eventually, it can no longer remain "dissolved" in the solution and it falls out (as chemists like to say) of solution. Now other solute molecules begin growing on the surface of the crystal and it keeps on getting bigger until there is an equilibrium reached between the solute molecules in the crystal and those still dissolved in the solvent.
