Background Agricultural Connections
Interest Approach – Engagement
 Ask your students, "What is fat?" "Is fat necessary in our diet?" Inform students that everyone needs some fat in their diets. It's true that many Americans eat too much fat, which can be unhealthy. However, some fats and fat in moderation is a healthy part of our diet.
 Make a list of the following foods on your board:
 Hamburger
 Tomatoes
 Ham
 Vegetable Oil
 Wheat
 Corn
 Ask a volunteer to circle all of the food items that begin its production on a farm. Ask another volunteer to identify where each food item originates. (Hamburger is meat from cattle, ham is meat from pigs, and wheat, corn, and tomatoes are all plants grown by farmers for us to eat.) Likely, students will not know that oil is also produced by a farmer.
 Explain to students that the seeds of many plants contain oil. A farmer grows the plant, harvests the seeds, and then presses the seeds to extract the oil. Some of the plants grown for their oil include: corn, safflower, canola, cottonseed, sunflower, or soybeans.
 If needed, help your students understand that the oil used when making a cake or brownies and the oil their parents cook with is the type of oil extracted from seeds.
Procedures
Activity 1: Dress it Up
Scientific Inquiry: Reading Labels
 Read Dress it Up and complete the Doodle Bugs.
 Review label reading. Explain that the Nutrition Facts on food labels tell you how many calories, grams of total fat, grams of saturated fat and grams of trans fat are in foods. Sometimes grams of monounsaturated and polyunsaturated fats are listed too. Show the class where to find serving sizes, total calories, total fat, saturated fat and trans fat on the Nutrition Facts label. Point out the different units of measurement such as tablespoons, calories and grams.
 Give each student or pair of students a set of food labels. Instruct your students to complete the Salad Dressing Nutrition Facts table. Remind students to record units of measurement.
 Students may work independently, in pairs or as a class to complete questions one to six.
 Place several vegetables and one tablespoon of each salad dressing on each student’s plate.
 Students will dip vegetables into the salad dressing to complete a taste test. Instruct students to answer the remaining questions.
Activity 2: Emulsify This
Scientific Inquiry: Immiscible
 Prior to beginning the activity, label the jars using small strips of masking tape and a permanent marker. Each group will need a jar labeled “A” and a jar labeled “B”.
 Read Emulsify This and complete Doodle Bugs.
 Separate the class into groups of four to eight students.
 Review the new vocabulary words: immiscible (liquids that normally don’t mix), emulsify (to blend), emulsifier (a substance that keeps two immiscible liquids from separating), interface (the line between two layers of liquids that don’t mix).
 Students will follow the Scientific Inquiry: Immiscible instructions to complete the lab.
 Students will take turns measuring the ingredients and shaking the jars.
 While observing the separation of the vinegar and oil, the class may discuss other kitchen emulsions such as mayonnaise, salad dressing, peanut butter and milk.
 After several minutes of observation, instruct students to complete the questions.
Activity 3: Mmmm Creamy
Scientific Inquiry: We All Scream for Ice Cream
 Read Mmmm Creamy and complete the Doodle Bugs.
 Pass out the Nutrition Facts labels for each ice cream to each student or pair of students.
 Review where to find serving sizes, calories and total fat on the Nutrition Facts labels.
 Then instruct students to complete the Ice Cream Nutrition Facts table. Remind students to record the units of measurement.
 Once students have completed the table, they will use the data to complete the bar graph.
 Finally, serve each student a small sample of each type of ice cream in his or her small cups. Ask students to label their cups “R” for regular, “RF” for reduced fat and “FF” for fatfree.
 Students will taste the ice cream and complete the Ice Cream Taste Test Facts table. Encourage students to use descriptive words when completing the chart.
 Students will finish the lab by answering questions one to three.
Concept Elaboration and Evaluation
After conducting these activities, review and summarize the following key concepts
 Fats and oils are found in various forms in the food we eat.
 Oil, used in cooking, is produced from seeds and plants that were grown by farmers.
 Fats and oils should be consumed sparingly.

Common Core Connections
Speaking and Listening: Anchor Standards

CCSS.ELALITERACY.CCRA.SL.1
CCSS.ELALITERACY.CCRA.SL.1Prepare for and participate effectively in a range of conversations and collaborations with diverse partners, building on others’ ideas and expressing their own clearly and persuasively.
Mathematics: Practice Standards

CCSS.MATH.PRACTICE.MP1
CCSS.MATH.PRACTICE.MP1Make sense of problems and persevere in solving them. Students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Students check their answers to problems using a different method, and they continually ask themselves, “Does this make sense?” They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.

CCSS.MATH.PRACTICE.MP2
CCSS.MATH.PRACTICE.MP2Reason abstractly and quantitatively. Students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved. Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.

CCSS.MATH.PRACTICE.MP4
CCSS.MATH.PRACTICE.MP4Model with mathematics. Students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. Students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later. They are able to identify important quantities in a practical situation and map their relationships using such tools as diagrams, twoway tables, graphs, flowcharts and formulas. They can analyze those relationships mathematically to draw conclusions.

CCSS.MATH.PRACTICE.MP5
CCSS.MATH.PRACTICE.MP5Use appropriate tools strategically. Students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Students at various grade levels are able to identify relevant external mathematical resources, such as digital content located on a website, and use them to pose or solve problems. They are able to use technological tools to explore and deepen their understandings of concepts.

CCSS.MATH.PRACTICE.MP7
CCSS.MATH.PRACTICE.MP7Look for and make use of structure. Students look closely to discern a pattern or structure. They recognize the significance of an existing line in a geometric figure and can use the strategy of drawing an auxiliary line for solving problems. They also can step back for an overview and shift perspective. They can see complicated things, such as some algebraic expressions, as single objects or as being composed of several objects.

CCSS.MATH.PRACTICE.MP8
CCSS.MATH.PRACTICE.MP8Look for and express regularity in repeated reasoning. Students notice if calculations are repeated, and look both for general methods and for shortcuts. As they work to solve a problem, students maintain oversight of the process, while attending to the details. They continually evaluate the reasonableness of their intermediate results.

Introduction to FoodMASTER:
FoodMASTER (Food, Mathematics and Science Teaching Enhancement Resource) is a compilation of programs aimed at using food as a tool to teach mathematics and science. It is our theory that if food is used as a tool to teach mathematics and science, students will be better prepared to demonstrate and apply mathematic and scientific knowledge. Because students encounter food on a daily basis, they have preexisting contextual experiences preparing them for learning new and relevant mathematics and science material.
Food is conducive to handson and virtual, inquirybased, active learning that uses multiple senses to engage students in the learning process. Utilizing food allows for an interdisciplinary approach to learning concepts and ideas in a variety of scientific subjects like general science, biology, chemistry, microbiology, nutrition and health. Additionally, food labs are a dynamic way to teach mathematics concepts such as numbers and operations, algebra, geometry, measurement and problem solving.
The knowledge and skill development that can be inspired by the FoodMASTER approach is limitless. Proper use of measurement tools, data collection and interpretation, application and generalization, classification and organization, graphing and comparative analysis, understanding chemical changes, observing functions of ingredients and controlling variables, pricing, critical thinking, selfdirecting learning, and team building are only a few of the potential knowledge and skill development areas for intermediate grade students experiencing FoodMASTER’s scientific inquiry labs.
Additional FoodMASTER lessons can be found to cover health and nutrition topics such as: Food Safety, Vegetables, Fruits, Milk and Cheese, Meat, Poultry and Fish, Eggs, Grains, Measurement, and Meal Management.
Background for this lesson:
Fat is a nutrient found in foods. The body uses fat for energy, growth and nerve and brain functions. Everyone needs some fat in their diet. However, many Americans eat too much fat. Fats are high in calories and the wrong kinds of fat can be unhealthy. For this reason, it is important to learn which fats are healthier and which are less healthy.
In this lesson, students will:
