This hands-on investigation helps students develop a practical understanding of solutes, solvents, and the formation of solutions through direct experimentation.

In this activity, students test the solubility of everyday substances—such as permanent marker, nail polish, correction fluid, and oil-based paint—in a range of common solvents including water, alcohol, acetone, and vinegar. They record their observations and apply their findings to real-world contexts through a series of thought-provoking reflection questions.

Two versions included for flexible delivery:

Guided Version – Equipment list and method are provided, allowing students to focus on predictions, experimental results, and analysis.
Student-Led Version – Students write their own equipment list and method, supporting skill development in planning and procedural thinking.
This resource features:

A hypothesis table for pre-lab predictions
Results table to track solubility observations
Real-world application questions that link chemistry to everyday experiences
Clear formatting for ease of use in a lab setting
Designed specifically for use in practical lessons, this activity supports observation, analysis, and scientific thinking in a laboratory context.
