Today we continue The Frozen Project: a 6-year-olds study of crystals…
What did you study next? Sugar crystals. I will call these “Sugar #1.”
How did you make them? It was sugar plus water, but it was a hot solution. So we melted the sugar into the water. Before we used the simple sugar solution, we let it cool.
What did you do with the sugar water solution when it was cool? We put two drops of the solution on the slide and put a cover slip on top.
What happened next? We had to wait and wait and wait and wait and wait for the solution to dry and crystals to form.
What were these crystals like? They were flat and beautiful. Some grew from beyond the cover slip. They were glittery.
Here is a sketch of what I saw:

Did you study something else? I studied salt again. I will call this “Salt #2.”
Why did you study the salt again? When we did the other salt experiment, mommy forgot that crystals grow up. So after we finished the first salt, we decided to study salt which was flat instead.
What did you do differently from the first salt experiment? We put a cover slip on the salt sample.
How were these images different from the first salt images? Some were more square and some made beautiful leaf patterns.

Did you do try sugar without a cover slip? Yes. I will call it “Sugar #2.”
What was the difference between sugar #1 and #2? Like the first salt without cover slip they grew upward on the slide causing them to be thick and chunky where in contrast sugar #1 was thin and elegant.
