Transcript of Dissolving Sugar Project

Dissolving Sugar Science Project
Question:
What type of sugar dissolves the fastest?
Hypothesis: We think the granulated sugar will dissolve the fastest in hot water.
Steps
1) Put 15 teaspoons of cold water in 3 of the 6 cups.

2) This next step requires 2 people. Have one person place 2 small sugar cubes in one cup, while the other person get ready to time how long it takes to dissolve.

3) Time how long it takes until the sugar cube is fully dissolved. If needed, extract the sugar from the cup and place on paper plate. Then, record your observations.

4) To measure the other sugars, measure 2 teaspoons of any sugar and repeat Steps 2-4.




Conclusion
After our experiment, our hypothesis was true. Not only did granulated sugar dissolve the fastest, it dissolved the fastest in cold water as well. We also think that stirring was probably a factor of the uneven times. For example, the powdered sugar got 56secs and 18secs. This was because we stirred more in one test so it probably spread the sugar and it dissolved faster. In conclusion, our hypothesis was correct and be sure to stir the same for each test for best results!

Background Research
We found out many things about sugar. White sugar is highly refined and is made from cane and/or beet. Brown sugar is the same as white sugar, but mixed with molasses to make a thick and moist texture. Molasses affects the color of brown sugar, depending on how much or how little molasses is added in. Powdered sugar is super fined sugar, and is referred as 10x sugar. Also, sifting can remove lumps from flour/powdered sugar, so it will make the powdered sugar less lumpy and more refined.

measuring spoons
flat surface
2 teaspoons granulated sugar

Steps Part 2
5) Then, measure 15 teaspoons of hot water in one cup.

6) This next step requires 2 people. Have one person place 2 small sugar cubes or 2 teaspoons of any sugar in one cup, while the other person get ready to time how long it takes to dissolve.

7) Record how long it takes to fully dissolve. If needed, extract the sugar from the cup and store it for later use. Then, record your observations.

8) To measure the other sugars, measure two teaspoons or 2 sugar cubes and repeat steps 5-8.

9) Dispose the dissolved sugars, plastic cups, and water after lab use.
