Growing Crystals Science Project

Tie the seed crystal to your fishing line and dangle it back into the liquid, supported by the popsicle stick across the top of the jar.

Growing crystals is a classic science project that demonstrates , nucleation , and crystallization . By dissolving a substance (the solute) into hot water until it can no longer dissolve, you create a saturated solution. As it cools, the water can't hold as much solute, forcing the particles to settle into highly ordered solid structures—crystals. Popular Materials & Methods growing crystals science project

Stir the alum into the hot water until it stops dissolving. You’ll see a little powder at the bottom—that’s good! It means the solution is saturated. Tie the seed crystal to your fishing line

If crystals are growing on the bottom instead of your string, they are "stealing" the material. Clean the jar and move your seed crystal to a fresh solution. As it cools, the water can't hold as
