Safe Chemistry Labs

12 virtual chemistry labs for grades 6–12: guided experiments, lab reports, answer keys and an hours log. No chemicals.

Real chemistry experiments for homeschool students in grades 6–12, with no acids, flames or mess at the kitchen table. Safe Chemistry Labs opens in its own tab and runs entirely inside the extension. Each of the 12 guided experiments takes 25 to 45 minutes and follows the scientific method: 1. Brief: the question, key words, materials, and the safety gear a real school classroom would need 2. Predict: the student writes a hypothesis, with sentence starters 3. Experiment: a hands-on bench where they drag reagents into test tubes, light a burner, read a balance or thermometer and record data 4. Analyze: questions about their own results, scored on the first try 5. Conclude: claim, evidence and reasoning 6. Report: a complete write-up to print or save as a PDF THE 12 EXPERIMENTS Signs of a Chemical Reaction, Conservation of Mass, Types of Reactions, Exothermic and Endothermic Reactions, Reaction Rates, Electrolysis of Water, Acid–Base Indicators, Measuring pH, Reactions of Acids and Bases, Titration, Flame Tests, and Hydrates: Percent Water.
