Help students discover why oil and water separate—and how emulsifiers bring them together—with this complete, classroom-ready lesson bundle. Designed for high school food science, culinary arts, chemistry, agriculture, and family and consumer sciences courses, this engaging 60-minute lesson connects emulsion science to familiar foods such as mayonnaise, salad dressing, milk, butter, and ice cream.

Students explore dispersed and continuous phases, oil-in-water and water-in-oil emulsions, hydrophilic and hydrophobic regions, droplet formation, and factors affecting emulsion stability. A low-cost, hands-on investigation allows students to compare oil-and-water mixtures prepared with and without an emulsifier while collecting and analyzing observable data.

The bundle includes nine editable Word files:

• Lesson objectives
• Engagement starter
• Complete lesson plan
• Student lesson notes
• Student worksheet
• Critical-thinking questions

• PowerPoint Slides
• Teacher guide

Complete answer keys, teacher directions, safety guidance, and coordinated activities make this practical lesson easy to implement with minimal preparation and no specialized laboratory equipment.
