This engaging lab activity helps students explore solubility, saturation, and mixture types through direct experimentation with common and classroom-safe substances.

In this experiment, students test the solubility of various materials—such as salt, flour, sugar, and copper compounds—in water. They determine whether each substance is soluble, and if so, how much is required to reach saturation. The activity also introduces key scientific distinctions between solutions, suspensions, and colloids.

This structured version includes the aim, method, and equipment list, making it easy to implement in a lab setting while still encouraging independent observation and critical thinking.

This resource features:

A pre-lab hypothesis activity to engage students in making predictions
A results table to track solubility and saturation of nine different substances
A solubility graphing task for data interpretation and visual learning
Analysis questions that connect experimental outcomes to scientific concepts
Real-world extension questions to deepen conceptual knowledge
