Dissolving Experiment Worksheet: Warm and Cold Water

Science experiments lesson 3: Dissolving sugar: warm vs cold water · Set 515 · 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.
