Science Buddies: "Ask an Expert"

My son and I found this science fair project here on science buddies. "Maple Syrup: For Pancakes, Waffles, and...Crystal Candy?"
We have tried the project 4 times now.
We are basically saposed to boil pure maple syrup until it is thick then put a dalop on a room temp cookie sheet and one that has ice on it. We are then saposed to watch the crystals grow.
Nothing.
We have tried boiling until it's almost pure sugar and tried boiling until just before it's thick. What are we doing wrong?
Are the crystals microscopic?
We thought this would be an awesome science project, he has already done most of the writen work for it.
Does anyone know how to make maple syrup crystals grow???????
Thanks.

Hope it will help!

Hi Cindyluwho - I'm sorry to hear that your son has not been seeing crystals form as expected in the project. In addition to the other thread that John pointed out, this thread also contains advice and troubleshooting for this project:

In addition, the advice from Donna, part of our team of Experts at Ask an Expert, may prove helpful if it turns out that your son doesn't observe crystals after another trial.

Here are a few additional suggestions and things to check that may help:

-- starting with the syrup at room temperature may help with crystal formation

--the humidity of the environment can affect crystal formation. How was the weather during testing?

-- make sure the pan is VERY clean. Water, oil or soap residue can cause a problem with the formation of crystals


Let us know how it is going and if you have additional questions.

Good luck with the project!
