Sugar Dissolution Experiment Analysis

The video tutorial investigates which type of sugar dissolves the fastest in water. The prediction was that brown sugar would dissolve the quickest due to its moisture content, followed by refined sugar, with raw sugar taking the longest due to its larger crystals. The experiment involved dissolving each type of sugar in the same amount of water and timing the process. Results showed that brown sugar dissolved in 13.5 seconds, refined sugar in 34.3 seconds, and raw sugar in 63.9 seconds, confirming the initial prediction. The experiment controlled variables like water temperature and amount, while the type of sugar was the independent variable. The conclusion confirmed the prediction, with brown sugar dissolving the fastest.

What was the initial prediction about which sugar would dissolve the fastest?

• All sugars dissolve at the same rate

• Brown sugar

• Refined sugar

• Raw sugar

Why was brown sugar predicted to dissolve the fastest?

• It is more refined

• It is moist

• It is less dense

• It has smaller crystals

How long did it take for the brown sugar to dissolve completely?

• 1 minute and 3.9 seconds

• 36 seconds

• 34.3 seconds

• 13.5 seconds

What was the result of the refined sugar test?

• It dissolved in 34.3 seconds

• It did not dissolve completely

• It dissolved slower than raw sugar

• It dissolved faster than brown sugar

Which sugar took the longest time to dissolve?
