Sugar Investigation
\\Input Variable
Outcome Variable
Temperature
Time taken for the sugar to dissolve
Volume of Water
Number of Stirs
Amount of Sugar
Type of Sugar
The input variable we are testing is the temperature to see if the time taken for the sugar to dissolve differs.
Prediction
I predict that when the temperature of the water increases, the time taken for the sugar to dissolve in the water will be quicker than dissolving at a low temperature.
This is because, the particles in a solid are very close together and are in a fixed position. The particles in a liquid are very close but are not in a fixed position causing them to flow over each other. So when a solid is put into a liquid, the liquid particles collide with the solid , causing the solid to get smaller and eventually dissolve. As heating the water, the particles will move more and collide more often with the sugar. This will cause the sugar to dissolve quicker.The particles never disappear they just become so broken down that they cannot be seen by the naked eye.
