What is the Best Solution to Dye Easter Eggs?
Students use red and blue litmus paper to determine the category of common substances. They then set up an experiment using vinegar, water, and ammonia (or milk of magnesia) to determine that acids make the best solution for dyeing...

Colorimetric Determination of the Concentration of Blue Food Coloring in Sport Drinks
Seventh graders determine the amount of blue food coloring in sports drinks and plot the concentration and absorbance data. They summarize the data and determine why companies need to know the amount of chemicals in their products.
Curated OER
Acid (and Base) Rainbows
Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...
