Lesson Aim: To introduce students to the math and science of nutrition.
Immigration Reform Bill Recap (20 minutes)
• Hand out charts showing voting data for support for the bill from August 2, 2013 and August 15, 2013. • Remind Ss that this shows how many people have voted to support the bill. • Ask Ss to look at the chart in pairs and discuss:
How many votes does each chart show?
What's the goal for the vote in each chart?
Has the goal been met?
Chest the web page and point to message. Who is receiving the message? How do they know who is your Senator and who is your Representative.
Do you remember if Congress passed the bill?
Will you vote? If so, google: Keystone and Commonsense Immigration Reform Bill
Kitchen Math (50 minutes) • Tell Ss: We're going to be doing Kitchen Math (WOB). • Ask: is there math in the kitchen? Is there math related to food? • Elicit: recipes, calories, food pricing, measurements of ingredients, etc. • Do you count your calories? Do you try to stay below a certain number of calories per day? • Why are calories important?
Counting Calories • T reads top paragraph of Counting Calories • T asks Ss to look at the calorie table. Who needs more calories, girls or boys? Do you believe this? • Part 1: Model first problem. • Ss do problems by themselves, then check their answers with their partners. • Part 2: Model first problem. • Ss do problems by themselves, then check their answers with their partners. • WCFB: Volunteers answer.
Nutrition Facts • T reads top paragraph and directions. • T asks Ss if they ever read Nutrition Labels on foods they buy. • Do they read them before or after they buy them or both? • Tell Ss that everyone looks for something different when they look at nutrition labels. I look for the sugar, because I don't want to eat too much sugar. There's sugar in everything, potato chips, salad dressing, etc.! What Ss look for when they read them? (total number of calories, number of servings in pkg., what percent fat? How much sugar? How much protein? • Ss figure out problems by themselves and then check their answers with their partner.
Nutrition Facts (40 minutes) • Go over nutrition vocabulary. Ask Ss if they know these words and to give a definition. Ask Ss for examples of foods that are high in each. • Vocabulary: carbohydrates, sodium, cholesterol, protein. Don't go over fat vocab, but give it to Ss.
• Hand out nutritional labels • Ask Ss to guess what the foods are.Write: potato chips, protein powder, ice cream, coke, and bacon on board. • Are these foods healthy or unhealthy? • 1 cup = 236 grams (google gram to cup convertor) • After they guess, look at each one and talk about what to watch out for:
(potato chips - fat, coke - sugar) What do you see on the label that might be harmful? What might be good for you?
Serving size. How much would you eat realistically?? 1/2 cup of ice cream? I would eat all of it!
• Research things you don't know. Names and labels can be deceptive.
• Write ingredients on the board. • Ask Ss what ingredients means. • Is this an important part of food labeling? Why? • Ask Ss if they look at ingredients of foods when they go grocery shopping. • Hand out ingredients primer.
• Ask Ss to work in pairs to talk about which of these foods is healthy. Rank from healthiest to least healthy. • Order of ingredients. If sugar is first, is this healthy? Ingredients in order of amount
• Ss discuss: what can you do to eat healthier? Are there foods you eat now that you will consider eating less of? Tell your partner one thing you can do to eat healthier. • Introducing: high fructose corn syrup (HFCS)
• Write High fructose corn syrup on board. • Ask Ss if they have every heard of it. Write (HFCS)
High fructose corn syrup is an industrial food product. It is not natural. It is extracted from corn stalks through a secret process. Since there is there is no chemical bond in HFCS, no digestion is required so it is more rapidly absorbed into your blood stream. Fructose goes right to the liver and triggers lipogenesis (the production of fats like triglycerides and cholesterol) this is why it is the major cause of liver damage in this country and causes a condition called “fatty liver” which affects 70 million people. The rapidly absorbed glucose triggers big spikes in insulin–our body’s major fat storage hormone. This leads to increases in appetite, weight gain, diabetes, heart disease, cancer, dementia, aging,and more. High doses of free fructose have been proven to punch holes in the intestinal lining allowing nasty byproducts of toxic gut bacteria and partially digested food proteins to enter your blood stream and trigger the inflammation that we know is at the root of obesity, diabetes, cancer, heart disease, dementia, and accelerated aging. And HFCS is contaminated with mercury.
• Foods that contain HFCS are:
Yogurts
Breads
Frozen pizzas
Cereal bars
Cocktail peanuts
Boxed macaroni and cheese
Salad Dressing
Tonic
Applesauce
Canned fruit
• Ss discuss: what can you do to eat healthier? Are there foods you eat now that you will consider eating less of? Tell your partner one thing you can do to eat healthier. • Hand out a foodlabel that can help guide Ss in how to interpret food labels.
Pollination is the transfer of pollen grains, the male sex cells of a flower, from the anther where they are produced to the receptive surface, or stigma, of the female organ of a flower. The honey bee is the most important insect that transfers pollen between flowers and between plants. Bees pollinate crop plants. In many states the estimated number of hives of bees has dropped drastically in recent years. For example, in Illinois the estimated number of hives dropped from 101,000 in 1964 to 46,000 in 1984. Because of the reduction in numbers of bees, growers in any state can no longer assume that there are sufficient numbers of bees nearby to produce the best possible crop from insectpollinated plants.
Honey bees are good pollinators for many reasons. Their hairy bodies trap pollen and carry it between flowers. The bees require large quantities of nectar and pollen to rear their young, and they visit flowers regularly in large numbers to obtain these foods.
Honey bees are most active at temperatures between 60 degrees F. (16 degrees C.) and 105 degrees F. (41 degrees C.). Winds above 15 miles per hour reduce their activity and stop it completely at about 25 miles per hour. When conditions for flight are not ideal, honey bees work close to their hives. Although they may fly as far as 5 miles in search of food, they usually go no farther than 1 to 1-1/2 miles in good weather. In unfavorable weather, bees may visit only those plants nearest the hive. They also tend to work closer to the hive in areas where there are large numbers of attractive plants in bloom.
