The experiment comprises two subexperiments:

• We emulsify oil
• Saponification of edible oil

For each subexperiment, the students are first provided with an overview of the materials to be used and safety information. This overview is followed by the detailed, step-by-step instructions for conducting the experiment. Afterwards, the students are asked to note their observations. Specific questions are used to guide the students as they analyze the results of the experiments. At the end, the students are asked probing questions related to the experiment (an answer sheet is available for teachers).

Notes:
• Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
