I was so happy when my both kids won special award and first price in the Science Fair Project. It is little harder to teach scientific words to elementary kids. But, if you teach any scientific terms with some experiment then kids can learn faster. These happens to my nine year old daughter. let’s begin with the project. Presentation of science project contains few steps.
Following are the main steps of any science fair project
1) Title of the project
2) Question problem/statement
3) Prediction/ Hypothesis
6) Data analysis and Graph/Diagram
7) Conclusion/Summary of the research
9) My Experience
Let’s start with all those steps: In my daughter’s own words with the help of all resources.
1) Title of the project:
“Cooling Effects on Sugar Crystals”
2) Question problem/statement:
Which temperature affects the growth of sugar crystals the most?
I think sugar crystals grow faster in the room temperature than the refrigerator based on several Google results and theory of crystalline structure.
4) Materials/Procedure:Materials and Equipment:
1) Get two jars and label it as “Jar A” and “jar B”
2) Get two pencils and two pipe cleaners. Wrap the pipe cleaner around the pencil and make sure it doesn’t touch the bottom of the jar at least two inches above the bottom.
3) Keep this pencils and pipe cleaners by side.
4) Get a pan; pour two cups of sugar and one cup of water. Stir it for 2 minutes.
5) Keep the pan on the burner and let it boil till bubbles appear. Let this step be done by parents.
6) Let it cool down for two minutes and pour this syrup equally into “jar A” and “Jar B”.
7) Pour two drops of food color in “Jar A”
8) Take two pencils wrapped with pipe cleaners and drop the unwrapped part of each pipe cleaner into each jar.
9) Now keep “Jar A”-red sugar syrup into the Refrigerator and “Jar B”- plain sugar syrup in a safe place and at room temperature. Cover with paper napkin to make it dust-free.
10) Now sugar crystals will grow on pipe cleaners.
11) Every 24 hours measure the growth of crystals of both sugar crystals for 4 days as shown in the Data chart.
12) Repeat all steps for Trial-2 and Trial-3.
1) Let an adult do the boiling and pouring part of this project.
2) Keep hot sugar syrup far from a little children.
1) Same amount of water and sugar.
2) Same brand of sugar.
3) Start growing crystals at the same time.
4) The same length of pipe cleaners.
1) The temperature of the crystal growth location that is cold and room temperature.
1) The growth rate of the sugar crystals.
2) Amount of chunks of crystals.
3) To determine the crystal growth rate, I defined the pipe cleaner with the most crystal growth as 100% and if no growth than it is 0%. I estimated the percentage between 0% to 100%.
6) Data analysis and Graph/Diagram
|Day||Amount(%) of crystal growth at room temperature||Amount of crystals growth at cold temperature|

- Graph of Day Vs Amount of crystal growth at room and cold temperature
Which temperature make crystals growth faster?
7) Conclusion/Summary of the research:
I accept my hypothesis because at room temperature, sugar crystals grow faster and chunks was bigger in compare with refrigerator temperature (cold).
The result of this experiment makes me wondering that it would be the same result if I use slat, snow flakes and other crystals.
Summary about Crystals: this is taken from the online library, wiki and other resources.
What is Crystals?
A crystal consists of solid matter that is formed from ordered, three-dimensional arrangement of atoms, molecules, ions.
It means forming crystals.
Crystal forms whenever solid is made out of fluid, vapor etc. Like sugar crystals is made up from carbon, hydrogen and oxygen atoms. Salt is made up from sodium and chloride ions and snow flake from water vapor.
Shapes of Crystals:
Shapes of Crystals:
There are about more than 20 shapes of crystals but most popular are cubes, hexagonal and prisms.
Examples of Crystals:
Table salt and sugar, snow flakes, Diamond,
sand, marble etc.
First scientist studied about crystals:
Crystallographer. After his name the studies of crystals growth, shape, geometry is called as “Crystallography”
What is sugar?
Sugar is a white powdery substance that we use to sweeten our food, but it is actually more than that. It is also known as “Sucrose” that comes from two source plants: Cane and Beet. Sugar forms crystals that are almost perfect cube shape. It is made of carbon, hydrogen and oxygen atoms.
3) I googled out a few words and learned about crystals, atoms, molecules, ions etc.
4) My mother helped in boiling sugar water syrup and pouring in the jar.
9) My Experience:
I was glad to do this fun learning experiment. I learned so many things about crystals like shapes, kinds, Crystallization, atoms etc. This was my first experience about making my own, yummy “rock sugar candy” too.
Make your child understand basic science about crystals and I will explain about atoms,molecules in a simple way in my next post.
Help them to do some science projects in this summer vacation. It will be fun learning process.
