This experiment-based test on laboratory safety is designed for lower secondary chemistry (grades 7–9) and supports CLIL and bilingual science teaching. It focuses on safe laboratory practice based on real classroom experience.

Students analyse hazard symbols, safety rules and laboratory behaviour using realistic scenarios. Instead of learning rules by heart, students apply their experimental experience to interpret risks and select appropriate safety measures.

The detailed reading text explains laboratory safety in age-appropriate language and highlights the importance of responsibility in experimental science. Tasks are structured along three cognitive levels: recalling safety rules, analysing hazard situations, and evaluating the consequences of unsafe behaviour.

A comprehensive 100-point marking scheme ensures transparent assessment and supports scientific responsibility and clear reasoning. This resource is ideal for inquiry-based chemistry lessons with a strong focus on safety.
