LI: To explore science equipment.
Our task was measuring an exact amount of sugar and dissolve in both hot and cold water to make a solution.
The equipment we used was:
- A petri dish
- A weighing machine
- Table sugar
- 200 ml beakers
- A pipette
- Thermometer
- Stopwatch
Method: We placed a petri dish on the weighing machine or scale. Fill a beaker with 100 ml of cold water, Measure 10 grams of sugar in the petri dish. Pour the 10 grams of sugar in the 100 ml of water in the beaker and stir. We used the stopwatch to time how long the sugar to dissolve into the water. We did the same with the warm water
Results:
Temperature of the cold water was 25 celsius and the time taken by sugar to dissolve in cold water was I minute and 10 seconds.
Temperature of the warm water was 84 celsius and the time taken by the sugar to dissolve in warm water was 17.18 seconds.
