Product Details

Soap-making is one of the oldest known chemical reactions involving organic compounds. Use the ancient craft of soap-making to show students a real-world application of chemistry—making products people use every day! The investigation begins with an introductory activity to make a bar of soap using a combination of natural fat and oil that is heated with a sodium hydroxide solution. The properties of the soap will then be investigated—its pH, texture and emulsifying action. The results provide a model for guided-inquiry design of an experiment to prepare soap with different oils or fats using a student-personalized recipe. As students observe the transformation of organic compounds from natural products into consumer products, they gain appreciation for the practical application of chemistry in the world around them!

Complete for 30 students working in pairs.

Performance Expectations

HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
