Description:
These simple experiments for the emulsification and saponification of fats are well suited as an introduction to the topic of digestion and metabolism in the human body. Starting from the experiment that merely demonstrates that fats can be split into fatty acids, the topic must then be related to human digestion. These teacher instructions provide information and suggestions for this. The materials and apparatus supplied are sufficient to allow eight groups of students to conduct the experiments simultaneously.
The experiment comprises two subexperiments:
• We emulsify oil
• Saponification of edible oil
Notes:
• Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
