What is a Supersaturated Solution?

By Janice VanCleave

Each solution is a mixture of sugar (sucrose) and water. Sugar is the solute and water the solvent. Solution A has twice as much sugar added to the same amount of water as does solution B. Thus, Solution A is more concentrated than is Solution B. You can also say that of the two solutions, A and B, Solution B is more dilute.

What is a Solution? How do You Saturated A Solution? A solution is  a homogeneous mixture, meaning it is the same throughout. A solution can be made of more than two substance, with one of the substances being the solvent and the substances that dissolve in the solvent are called solutes. You make and use […]

Snowflakes

By Janice VanCleave

Six-Sided Snowflake Models The snow flake to the right gives the basic design of a six-sided snowflake. You can be as creative as you dare in making snowflake models. Just be sure they have six major sides. A paper snowflake can be cut from a round paper coffee filter. The procedure for folding and cutting […]
