LESSON 9: MAIN NUTRIENT GROUPS IN FOOD FACTORS OF SCIENTIFIC LITERACY AND FOUNDATIONAL OBJECTIVES, LEARNING OBJECTIVES, SCIENCE 10 BIBLIOGRAPHY
NEXT LESSON

WHAT ARE NUTRIENTS AND HOW ARE THEY CLASSIFIED?

FOOD IS OFEN PLACED IN CATEGORIES AS SHOWN IN CANADA'S FOOD GUIDE. HERE FOOD IS PLACED IN ONE OF FOUR GROUPS:

  • GRAINS AND PRODUCE
  • VEGETABLES AND FRUITS
  • DAIRY PRODUCTS
  • MEAT AND ALTERNATIVES

FOODS THAT WE EAT HAVE TWO TYPES OF COMPONENTS:

  1. NUTRITIOUS PARTS: THIS PART OF THE FOOD CONSISTS OF MOLECULES THAT THE BODY USES FOR ENERGY, GROWTH, MAINTENANCE OF CELLS AND CELL REPAIR. THE NUTRITIOUS PARTS OF FOOD ARE CALLED NUTRIENTS.
  2. NONNUTRITIOUS PARTS: THIS PART OF THE FOOD CONSISTS OF MOLECULES THAT THE BODY IS NOT CAPABLE OF DIGESTING AND THUS THIS PART OF THE FOOD IS EXCRETED AS WASTE.

EATING A BALANCED DIET WILL PROVIDE YOUR BODY WITH THE NUTRITION IT NEEDS. WITHIN ANY FOOD, THERE MAY BE SEVERAL NUTRIENTS. THE FOOD COMPONENTS OR NUTRIENTS ARE CLASSIFIED IN GROUPS AS WELL. THE MAIN NUTRIENT GROUPS ARE:

  • PROTEIN
  • CARBOHYDRATES
  • FAT
  • VITAMINS
  • MINERALS
  • WATER

IN THIS LESSON YOU WILL LEARN WHY OUR BODIES REQUIRE EACH NUTRIENT. YOU WILL THEN CLASSIFY FOODS INTO ONE OF THE MAIN NUTRIENT GROUPS.

ACTIVITY

YOUR ACTIVITY INVOLVES DOING THREE THINGS:

LEARNING

YOUR FIRST TASK IS TO LEARN ABOUT THE MAIN NUTRIENT GROUPS. THE STUDENTS IN YOUR CLASS WILL BE GROUPED TO DO A JIGSAW. THERE WILL BE SIX GROUPS OF STUDENTS, WITH EACH GROUP ASSIGNED ONE MAIN NUTRIENT. YOU WILL LEARN ABOUT THIS ONE NUTRIENT IN DEPTH: WHAT IS THE NUTRIENT, WHAT IS THE NUTRIENT'S ROLE IN OUR BODY, WHAT HAPPENS IF OUR BODY LACKS THIS NUTRIENT OR GETS TOO MUCH OF IT, AND WHAT FOODS PROVIDE THIS NUTRIENT.

TO DO YOUR LEARNING, YOU CAN USE YOUR CHEMICALS IN ACTION TEXTBOOK, OR USE OTHER BOOKS YOU MAY FIND IN YOUR LIBRARY OR YOU CAN USE INFORMATION YOU FIND ON THE INTERNET. IF YOU CHOOSE TO USE THE INTERNET AS YOUR RESOURCE, HERE ARE A FEW SITES THAT YOU MAY FIND USEFUL. FEEL FREE TO DO YOUR OWN INTERNET SEARCH.

  • SITE A: NUTRIENT GROUPS BY THE LUNG ASSOCIATION
  • SITE B: KIDSHEALTH FOR KIDS SITE - SCROLL DOWN TO FIND LINKS TO THE NUTRIENT GROUPS
  • SITE C: WORLD BOOK MEDICAL ENCYLOPEDIA ENTRY ABOUT NUTRIENTS
  • SITE D: ENEREX BOTANICALS LTD. INFORMATION ON NUTRIENTS
  • SITE E: NUTRITION AND FOOD MANAGEMENT - SELECT THE NUTRIENT LINKS ON THE RIGHT SIDE OF THE SCREEN
  • SITE F: TRADITIONAL FOOD NUTRIENT DATA

MAKE A POSTER

MAKE A POSTER ABOUT YOUR NUTRIENT. THIS POSTER SHOULD "TEACH OTHERS" ABOUT THIS NUTRIENT. INCLUDE IN YOUR POSTER: WHAT IS THE NUTRIENT, WHAT IS THE NUTRIENT'S ROLE IN THE BODY, WHAT HAPPENS IF OUR BODY LACKS THIS NUTRIENT, WHAT HAPPENS IF THE BODY HAS TOO MUCH OF THE NUTRIENT, AND WHAT FOODS PROVIDE THIS NUTRIENT. PUT YOUR FULL NAME IN THE BOTTOM RIGHT HAND CORNER OF THIS POSTER.

SHARING OR TEACHING OTHERS

YOU WILL SHARE YOUR UNDERSTANDING OF YOUR NUTRIENT WITH 5 OTHER CLASSMATES WHO HAVE DONE DIFFERENT NUTRIENTS THAN YOU. TAKE TURNS IN YOUR GROUP TO "TEACH" THE OTHER MEMBERS ABOUT YOUR NUTRIENT. GIVE A COPY OF YOUR NUTRIENT POSTER TO EACH OF THE MEMBERS IN YOUR GROUP. BE SURE THAT YOUR NAME IS IN THE BOTTOM RIGHT HAND CORNER OF YOUR POSTER. CLICK HERE TO GET COPYING INFORMATION.
