What are the ideas from today?
- Dissolving
What factors affect dissolving?
- Surface, Mixing, and Temperature
Aim method and Results:
Aim: To figure out the rate of dissolving depending on temperature and string.
Method: To get 50ml of water and a spatula of sugar, depending on what one we were doing. 1 2 3 4. We then put the sugar into the beaker of water, and timed how long it took to dissolve
These are the results from all groups, the number up the top is all the seconds combined, and the number below it. We thought that the Hot water, sugar, and string would be the fastest because of the hot water giving the sugar more energy to move and dissolve, we also thought the Coldwater, sugar, and no stiring Would be the slowest because your not stirring it which is isn't getting around which then the cold water takes slower to dissolve the sugar.
Hi Jaz really interesting results, I'm pleased you explained the headings as I was wondering what they meant. I was wondering if next time you could try taking photos or video clips to really reinforce your point?
