To discover if sugar crystals grow bigger in a certain type of liquid (water, unsweetened apple juice or 7-Up).
In order to discover which sugar crystals grows the biggest, I will use three different types of liquid. I will boil each liquid for 3 minutes. I will measure 125 ml of liquid and pour it into a Mason jar. 375 ml of sugar will be poured into a Mason jar and stirred with a spoon for 1 minute. A bamboo skewer will be placed in the jar. The jars will be open to the air. The jars will be untouched and sitting on the dinning room table. Observations will be written in my journal. At the end of the two weeks, I will calculate the mass of the crystals, using an electronic balance.
It would be expected that 7-up will produce the largest sugar crystal formation on the bamboo skewer. My hypothesis was rejected. The unsweetened apple juice liquid grew the biggest sugar crystals and not the 7-Up and the water was the smallest mass. This was assessed by measuring the mass of each crystal, using an electronic balance (quantitative measurements) and qualitative observations (in the form of anecdotal notes). To make sure this was correct, I would have repeated the experiment again to ensure accuracy.
If someone wanted to make sugar crystal on a bamboo skewer, for a birthday party, or to sweeten a hot drink, it would be important to know what solution/liquid would make it grow big in a short amount of time span.
