Our focus for the technological discovery regarding science exploration on laboratory equipment was based around understanding how the temperature of the water can change how quick a substance, such as sugar, can dissolve into a liquid form or substance solution and we used different types of scientific equipment to perform this experiment.
The creative task that we were set was to measure 100ml of cold water into a beaker using our knowledge of meniscus to determine an accurate measurement. Then, using a scale or weighing machine, we calculated exactly 10 grams of sugar on a petri dish disregarding the weight of the petri dish. Once we measured the sugar, we used a thermometer to determine the exact temperature of the water. Then, we poured the sugar into the cold water and used a stopwatch to see how long it took for the sugar to dissolve. We repeated this process for hot water.
I found this science task easy because I am familiar with measurement and performing accurate calculations regarding temperature and specific amounts. I enjoyed this task because I was able to use the different laboratory equipment to perform this experiment and I had a lot of fun recording and comparing results.
The information about the equipment we used can be found recorded and listed on the document above.
The temperature of the cold water was 20 degrees celsius.
The time it took for the sugar to dissolve was 59.66 seconds.
The temperature of the hot water was 75 degrees celsius.
It took 17.10 seconds for the sugar to dissolve.
Well done Bella!!You are doing really good.
