AIM: What is the role of carbohydrates in our diet? DO NOW: How much of our daily diet should consist of carbohydrates? Why do you think this? Learning Objectives: I can … ● define carbohydrate ● distinguish between monosaccharides, disaccharides and polysaccharides Carbohydrates: ● nutrients composed of carbon, hydrogen, and oxygen ● supply energy for your body’s functions Types of Carbohydrates ● monosaccharides - simplest carbohydrate molecules ○ A.K.A. simple sugars ○ ex: glucose Types of Carbohydrates ● disaccharides - 2 monosaccharides joined together ○ ex: table sugar (sucrose) Types of Carbohydrates ● polysaccharides - multiple monosaccharides joined together ○ ex: starch Check for Understanding: 1. Based on the image to the right, is maltose a carbohydrate? 2. If yes, classify it as a monosaccharide, disaccharide, or a polysaccharide. Carbohydrates & Energy ● 1 g of carbohydrates = 4 calories Hochman Activity: 1.

Carbohydrates are an important nutrient, so … ● ● Write/Pair/Share ● Brainstorm a list of as many carbohydrates as you can (1 minute) ● Discuss your list with your groups and compile one big list! Student List (PD 1) Student List (PD 4) Student List (PD 6) Turn & Talk: Are any of the following examples on the previous list a staple carbohydrate from your culture? Exit Ticket: Rank yourself 1-5 (1=bad ; 5= great) on your demonstration of each of today’s learning objectives (total 2 rankings) ● define carbohydrate ● distinguish between monosaccharides, disaccharides and polysaccharides Explain why you selected this ranking using at least 2 sentences for each ranking (total 4 sentences). Extension: Where do you think the average U.S. citizen obtains most of their carbohydrates? ● ● ● ● Wheat-based breads Potatoes Sugary snacks and desserts Soft drinks (sodas) AIM: What is the role of fats in our diet? DO NOW: Is there such a thing as a “healthy” fat? What do you think are some examples of a “healthy” fat? Learning Objectives: I can … ● distinguish between the structures saturated fats and unsaturated fats ● describe the effects of saturated fats on human health Fats: ● nutrients composed of carbon, hydrogen, and oxygen ○ contains fewer oxygen atoms than carbs ● source of energy for our body Fat & Energy: ● 1 g of fat = 9 calories “Good Fats” ● monounsaturated fat - only 1 C=C double bond “Good Fats” ● monounsaturated fat - only 1 C=C double bond “Good Fats” ● polyunsaturated fat - 2 or more C=C double bond “Good Fats” ● polyunsaturated fat - 2 or more C=C double bond “Bad Fats” ● saturated fat - no C=C double bond ○ can raise chloresterol and lead to heart disease “Bad Fats” ● saturated fat - no C=C double bond ○ can raise cholesterol and lead to heart disease “Bad Fats” ● trans-fat - manufacturers add hydrogen to the fat molecules in vegetable oils ○ “partially hydrogenated oil” on ingredient labels Write/Pair/Share: Based on the fat information on nutrition label to the right, is this a food you would want to put into your daily diet? Why or why not? Hochman Activity: 1. Saturated fats are different than unsaturated fats because … ● ● 2. Saturated fats are different than unsaturated fats, but … ● ● 3. Saturated fats are different than unsaturated fats, so … ● ● Exit Ticket: Rank yourself 1-5 (1=bad ; 5= great) on your demonstration of each of today’s learning objectives (total 2 rankings) ● distinguish between the structures saturated fats and unsaturated fats ● describe the effects of saturated fats on human health Explain why you selected this ranking using at least 2 sentences for each ranking (total 4 sentences).
