Common Core Standards addressed: S8P1: Students will examine the scientific view of the nature of matter b. Describe the difference between pure substances (elements and compounds) and mixtures Materials: Seasonal, preferably locally grown fruit Whipping cream, vanilla, sugar Mixing bowl Serving bowl Flexible cutting boards Butter knives Whisk Serving spoon Disposable cups/plates, spoons Time needed: 70-­‐80 minutes Vocabulary: Matter Pure Substance Element Compound Mixture Heterogeneous Homogeneous Solution Suspension Alloy Colloid Plan for assessment: Activity quizzing students on whether various items are an element, compound, or mixture Farm to School Lesson Plan Concept: Matter and Mixtures Objective: Students will learn about pure substances (elements and compounds) and mixtures (homogenous and heterogeneous) and prepare a healthy dish representing the material learned. Lesson Outline: Opening 20 minutes Instructor will discuss vocabulary terms. Assessment: After material is taught, photos of various items will be shown. Students will answer whether they are an element, compound or mixture. If item is an element, they will name the symbol of that element on the periodic table. If the item is a compound they will name the chemical formula. If the item is a mixture they will state whether it is homogeneous or heterogeneous and whether it is a solution, suspension, alloy, or colloid. Work Session 40-­‐50 minutes Instructor will go over proper sanitary, food handling, and safety procedures and students will wash hands. Groups will be assigned jobs cutting fruits and making whipped cream. All students will have the opportunity to whisk the whipped cream. Instructor will collect all cut fruits and whipped cream and combine the mixture while asking students why they made a fruit salad. Students should answer that the fruit salad is a heterogeneous mixture and the whipped cream is a homogeneous colloid. Closing 10 minutes Students will serve and eat fruit salad while reviewing the material taught. Cleanup of classroom and materials used. Alternatives: Any type of salad can be made instead of a fruit salad Lesson developed by: Sumer Ladd, FoodCorps Service Member 2014
