Science Sunday ~ The Decomposition of Sugar


Dawson has been learning about the basic patterns of all life. One that we studied this week is: Life Runs on Sugar.

From The Way Life Works by Mahlon Hoagland, "Sugars are simple, energy-packed chains of three to seven carbon atoms festooned with hydrogens and oxygens." Sugar is carbon and water fused together. When sugar is heated, it breaks down into it's original carbon and water elements.

So, to demonstrate the decomposition of sugar, we did the following experiment:

Dawson poured 1/2 cup of sugar into a small pan and heated it until the hydrogen and oxygen were revealed in their natural combined form: water.


As it was broken down into the carbon element, it turn into a blackish  color.


Once the sugar was caramelized into a liquid form, he slowly added 1/2 cup of water. It sizzled and popped, so he poured slowly and stayed back.


Part of it crystalized immediately and it tasted like rock candy.

The sugar was decomposed and made into a completely different substance. Had we wanted, we could have continued to heat and stir it until it was pure caramel, and used it as sauce over ice cream or another dessert.

This is what you DON'T want to do: Turn on the burner, and take someone's word for it that it takes about 5-10 minutes for the sugar to turn into liquid form. It only takes a couple of minutes, at least with an electric stove top.


I was busy making the beds. Apparently Dawson didn't see the smoke. Hmmmm ... That sure didn't look like something we wanted to serve on a dessert.

  1. HA!!! I bet that (the last picture) was exciting...and smelled lovely. ;)We have learned we can't take anyone's word for science because we have HORRIBLE luck with experiments. I'm pretty sure you don't want to serve that last picture on dessert. :) Good experiment, though, and one we might have to replicate since we're talking about sugar here too!

  2. I love this! We make caramel from time to time, but I never thought of using it as a science demo. Wonderful!

  3. OH, I've done that last part a time or two. It's going great and then you get distracted...... and then icky brown mess.

We all know that in this crazy world of homeschooling, we need all the (adult) support we can get. Please leave a comment if you so wish!

CTC Math {Schoolhouse Review}

We found our groove with math this year. I found a curriculum that both of the kids respond well to and seem to enjoy (as much as one can enjoy math). We have spent the whole year learning the ins and outs of multiplication and were just a few lessons away from being ready to move onto the next year-long level on division. And then an opportunity to review the 12 Month Family Plan from  CTC Math became available. To be honest, I wasn't very enthusiastic. I mean, why mess with the methods that have worked so well? When I was chosen to review the product I didn't go into it with the level of enthusiasm that it deserved. We have been using a dvd/workbook curriculum with great success. The 12 Month Family Plan from CTC Math is a web based curriculum. As we have not had a lot of luck with those types of programs, I went into this review with a negative attitude. And then my socks were knocked off by how great it is. In fact it is so great that we are going to continue to ...

Veritas Press Self-Paced History: Old Testament and Ancient Egypt (Schoolhouse Review)

For the past several weeks we have been reviewing Veritas Press Self-Paced History: Old Testament and Ancient Egypt and the Old Testament and Ancient Egypt Flashcards  from Veritas Press . As we were entering into our more easy-going summer schedule, and had just concluded a two-year Old Testament Bible course, I was happy to try out this product as it appeared to be something that Eli and Brynne could do together, alone, and would act as a review of the Old Testament presented in a different way. And I was right. Each Veritas Press Self-Paced History program includes 160 lessons teaching about 32 events in history. They are designed for children in grades 2-6, and it is recommended that the student be a minimum of 7 years of age at the time of the first lesson. What We Received We received a full one-year subscription, for one child, to the online Veritas Press Self-Paced History: Old Testament and Ancient Egypt program and the accompanying Old Testament and Ancien...

Cells ~ It's What's for Dinner

Dawson made edible cells on Friday. He made an animal cell pizza ... and a plant cell chocolate chip cookie ... He reviewed what he's learned about cells the past two weeks, and I had dinner made by someone else. Win, win!! I am linking up at Science Sunday at Adventures in Mommydom.
