These activities help students identify and compare basic food groups.
*NOTE: Activities increase in diffulculty. Educators/Parents may want to work through all
activities or choose those most appropriate for their students/children.
(BACKGROUND INFORMATION)
What do we already know about protein?
- Protein is one of six essential nutrients needed by the human body.
- Protein is made up of carbon, nitrogen, sulfur, oxygen, and hydrogen.
- Protein helps build and repair our bodies.
Activity One - Food Sort

magazines, scissors, glue, three colors of construction paper (one to identify proteins, one to indicate carbohydrates, one to identify fats)

- As a group, discuss the basic food groups. For this activity, students will be sorting foods into
only three of the six groups — fats, carbohydrates, and proteins. Be sure to discuss that many foods fall into more than one category.
- Give students magazines and scissors. Ask them to look through brochures and magazines
for pictures of foods.
- Students will sort these pictures into food groups. Identify a particular color of construction
paper to represent each group. Ask students to glue the pictures on the appropriate
construction paper.
- As a group, discuss what common attributes are found in the foods.
Extension Activity
Encourage students to keep a log of the foods that they eat in a day. Help them identify what foods were proteins, carbohydrates, and fats.
Activity Two - Food Bingo

Bingo cards with the words protein, carbohydrate, and fat in the squares; food words or pictures on slips of paper; Bingo chips or bean counters

- Give each student a Bingo card and Bingo chips or counters.
- Call a food word or show a food picture.
- Students must decide if the food is a protein, carbohydrate, or fat and mark the square.
- When they have a completed row, they call Bingo.
- Students must justify their choices.
Activity Three - Food Pyramid

Food pyramid chart, pictures of different foods (You may use the pictures from the first activity.)

- Draw a pyramid shape on the board. Discuss how the shape indicates the amount of each
type of food you should eat. What would a food rectangle suggest about the amounts of each type food we should eat?
- Fill the pyramid with examples of the food groups.
- How could you translate what you’ve learned into your everyday life?
EXTENSION ACTIVITY
Ask the cafeteria manager to discuss food choices for the school based upon the food pyramid. Take a “field trip” to the grocery
store to identify foods. Plan a menu that reflects the food pyramid.
DID YOU KNOW?
Did you know that if you eat a piece of meat, the proteins and fats must be broken into smaller molecules so that
your body can absorb them? A protein molecule is made up of many amino acids. It takes several enzymes in the stomach and
in the small intestine to digest proteins.
