Product Description
Students will distinguish between physical change and chemical change by completing the process of saponification (making soap). Additionally, students will observe an exothermic reaction. This process creates very hot liquids and strong fumes that require ventilation. Do not let students take the soap home right away. Test it with the pH strips, each day, until the pH level is at an eight or nine.

The product contains three complete labs that are differentiated for all of your students.

3 Differentiated Labs

Dependent Student Lab - A complete lab. This level is written with a combination of procedural instructions and inquiry questions. They are moderately student-centered with guided inquiry questions throughout the lab. Suggested for on-level learners.
Modified Student Lab - A complete lab. This level provides the most structured lab experience. The lessons may eliminate parts of the lab and change the questioning to include sentence stems or multiple choice questions. Suggested for learners with modifications.
Independent Student Lab - A complete lab. This level is the most student-centered experience. Suggestions are made for the students to get started, but most of the decisions will be student-centered. The students will be responsible for most aspects of the lab and will have the least guidance. Suggested for advanced learners.
