Acids and Bases - Vinegar II
Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental lesson, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of unknown pH.
Curated OER
Sour and Bitter: Acids and Bases
Tenth graders distinguish between acids and bases. In this pH lesson, 10th graders view a PowerPoint and discuss the characteristics of an acid and a base. They investigate natural substances to determine the pH level of each.

Aspirin Analysis
Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.
Carnegie Mellon University
Ocean Acidification
After brainstorming what they know about ocean acidification, youngsters place eggs in acid to determine the effects on calcium-containing organisms, and add carbon dioxide to solutions with sea shell material to discover the impact on pH.
