Curated OER
Weathering Lab
In this weathering worksheet, students use limestone chips and acidic solutions of pH 2 and 7 to determine if acidic solutions contribute to the weathering of rocks. Students determine which pH weathered the rocks the most.

Middle School Chemistry: Neutralizing Acids and Bases
Students will use citric acid and sodium carbonate solutions to see that adding a base to an acidic solution makes the solution less acidic. Students will then use a base to help them identify which of two acidic solutions is more...
