Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...
