Title: Nutrition: Comparing and Contrasting Past and Present Practices

Grade level(s): 9-12

Time frame: 2 to 3 days

Subject matter: Science (Biology/Anatomy) and Health

Teacher information

School: Dupo CUSD 196 High School

City, State:Dupo, IL

AAM/TPS Consortium: SIUE

Lesson plan Rationale or Understanding Goal: Students will be comparing and contrasting past nutritional ideals with today’s ideals. Students will also hypothesize reasons for the increased obesity rate today. Using learned information, students will construct posters that will inform others of good nutrition. As an extension, students can also replicate a previously conducted experiment that will determine the value of a nutritional diet.

Background Information for Activity:

Lecture notes on nutrition prior to this lesson. Have copies on-hand of the “past” nutrition posters from the Library of Congress – . Also needed is information from the Department of Agriculture’s Food Pyramid webisite – (this can be done prior to this lesson in a computer lab)

Objectives:

• Students will observe, analyze, and determine if the nutritional posters of the past are still relevant in today’s society

• Students will observe, read, identify, and analyze some of today’s nutritional ideals and suggestions

• Students will compare and contrast the past and present nutrition information

• Students will discuss reasons why the obesity problem is great in the U.S.

• Students will construct posters that have relevance about nutrition today, and will display these posters to help make other students aware of good nutrition.

• If time permits, students will replicate a previous experiment to determine the value of good nutrition in rats(mice or hamsters)

Purpose of Library of Congress Resource:

o Library items give students the opportunity to closely examine items (posters/pictures) from the past and compare their information with items from today.

State Standard/s:

STATE GOAL 11: Understand the processes of scientific inquiry and technological design to investigate questions, conduct experiments and solve problems. 11.A.4a-f. This goal is met through doing the experiment in the above objectives

State Goal 13: Understand the relationships among science, technology and society in historical and contemporary contexts.

13.B.4e Evaluate claims derived from purported scientific studies used in advertising and marketing strategies

Resources or Materials needed:

1. Bibliographic Information:

2. Other Web Resources:

▪ U.S. Department of Agriculture Food Pyramid website

”.

3. Students will need poster board, construction paper, markers, scissors, glue, etc.

4. If experiment is to be conducted: rats or hamsters, cages, food for diet to be used in the experiment, etc.

Methods:

Modeling Activity:

1. Show the students the nutrition poster/pictures of the past and ask them if they think they are from the past or present, and why. Characteristics of the are, poster content, clothing styles from the pictures Discuss with them that the poster/pictures are from the 1930’s -1940’s

2. .Brainstorm and discuss what nutritional messages are in the poster/pictures and then discuss and brainstorm what nutritional issues we are dealing with right now. These ideas are to be written on the board. Ideas will vary. The “past” posters are very simple in style and in the information given. They are not “flashy” like a lot of posters today. The rate of obesity should also be mentioned as an issue of today. Some information from the food pyramid website should be given as well.

3. Have students write a compare/contrast paper or chart with the “old” and “newer” nutrition information. Old – foods more simpler less processed, etc.. Newer – more info on the different types of fats (saturated, unsaturated, trans), confusion on portion size, etc. Both explaining the importance of a balanced diet. How were the diets(and activities) of then and now related to obesity.

4. .After observing, discussing, and writing, have the students list a couple of good nutritional practices and what can be done to implement these practices in our lives. Eating more whole grains, eat less processed, high-fat foods, eat more varieties of vegetables, eat lean proteins, etc

Student Activity:

1. Students will create a nutrition poster that will be hung around the school promoting present issues and good nutrition.

2. If time permits, students will also replicate the experiment done from the photo from the Library of Congress to determine if the same nutritional diet then would have the same effect as now, and to verify previous scientist work..

Formal Assessment:

o Students will be evaluated on their participation in discussions and brainstorming ideas

o Students will be assessed in the production of their nutrition posters

o Students will be evaluated on technique of lab practices and completeness of the scientific method
