Making a Salt for an Acid and Base
Copper Sulfate creation with the water bath for improved safety. Using the water bath stops the students heating the acid up too much and reduces the hazards.
Refraction
Using a @pascoscientific light source in daylight to do a refraction experiment. It was bright enough to work and work well.
