Dissolving Experiment Worksheet: Warm and Cold Water

Science experiments lesson 3: Dissolving sugar: warm vs cold water · Set 171 · 40 questions

What you do (Warm, stir, small): 1. An adult pours the same amount of warm water and cold water into two glasses. 2. Add one level teaspoon of sugar to each at the same time. 3. Stir each the same number of times and time how long the sugar takes to vanish. 4. Look, do not taste — then compare the two times.
