1. What type of sugar dissolves better in which temperature of water? Raw SugarRaw castor SugarBrown Sugar

2. Raw Castor sugar appears to be very fine grain

3. Raw Sugar appears to have larger grains than the Castor Sugar

4. Brown Sugar is a lot more dense than that of the other two sugars. It tends to “clump” together more and is not as grainy like the other sugars

5. Cold Water Water from the Fridge Tap Water Water out of the tap Hot Water Boiling water from Jug What type of water?

6. Cold water out of the fridge – No sugar will dissolve in this water Tap Water – The Raw Castor sugar may dissolve best in tap water Boiling water - All three sugars will dissolve in hot water

7. Raw Sugar Raw Castor Sugar Brown Sugar

8. As predicted no sugars dissolved in the cold water

9. Raw Sugar Raw Castor Sugar Brown Sugar

10. As you can see from the pictures the brown sugar dissolved the best out of the three different types of sugar in tap water

11. Raw Sugar Raw Castor Sugar Brown Sugar

12. Using the boiling water, the raw castor sugar and the brown sugar dissolved the best. Some of the raw sugar dissolved but not all of it.

13. Kevin C de Berg put it in a really simple way by explaining that the sugar particles are broken down by the water into smaller particles that you cannot see with the naked eye. (Kevin C de Berg)

14. So what does this mean? Because the Brown sugar dissolved in both the tap water and the Boiling water does this mean that this is the answer to our question?

15. Does Brown Sugar dissolve the best in water? Because it dissolved in 2 different temperatures of water.

16. Before completing the fair testing we would need to ask the following questions: 1. As the Brown sugar was tested last in all three tests – did the temperature of the water change at all over this time? For example did the tap water get hotter or colder during the course of the investigation? 2. Did the amount of sugar used, contribute to whether it dissolved, or how long it took to dissolve? 3. Did the amount of water used contribute to whether the sugar dissolved and how long it took to dissolve?
