Topic 3 - Trying out laboratory equipment

Hello everyone this is what we did at Tamaki Collage for Science. We used Lab equipment.   

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

 

1. Thermometer

2. Weighing Machine

3. Stop Watch

4. Spatula

5. Pipette  

 

Method: We placed a petri dish on the weighing machines or scales. We used a spatula to measure the sugar. We put the sugar into a 200ml beaker fulled with water and then timed it to see how long it would take. Then we did hot water. We did that until the the sugar dissolved. We used a thermometer to see the temp of the water. We used 10grams of sugar and 100ml of cold and hot water. 

 

Results:  Temp of cold water = 23

Temp of hot water = 80

Time taken by water to dissolve in cold water = 1.20

Time taken by water to dissolve in hot water = 16
