Tech @ Tamaki Stem/Science

Aim or Purpose: 1. Measure an exact amount of sugar and dissolve in water to make a solution.

Thermometer
Weighing Machine
Stop Watch
Spatula

Pipette

Cold Water:

Hot Water:

Method: Measured the cold water and timed the sugar being dissolved in the cold water. We then measured the hot water and timed the sugar being dissolved in the hot water. The temperature for the cold water was 23 and the time was 1.38 sec. The hot water temperature was 77 and time was 22.43.

Result:
Temp of cold water = 23
Temp of hot water = 77
Time taken by water to dissolve in cold water = 1.38
Time taken by water to dissolve in hot water = 22.43

Hello everyone, it's me Finau. Today we had our stem/science class. We were measuring and checking the temperature of hot and cold water.  We also dissolved the sugar in the cold and hot water. What was really interesting for me was how the sugar dissolved in less than 30 seconds in the hot water but it took kind of a long time when it was in the cold water. I hope you have enjoyed this post. Please leave a positive comment on my blog. Bye!
