This experiment-based test on water and its properties is designed for lower secondary chemistry (grades 7–9) and supports CLIL and bilingual science teaching. The assessment is closely linked to hands-on classroom experiments while remaining fully self-contained.

Students analyse experiments on surface tension, capillary action and solubility, using authentic classroom observations as evidence. Effects such as floating paper clips or rising water in filter paper help students understand why water behaves differently from many other liquids.

The detailed reading text explains these properties in age-appropriate language and highlights the model character of scientific explanations. Tasks are structured along three cognitive levels: recalling properties, analysing experimental observations, and evaluating the importance of water for life and everyday use.

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