Have you ever wondered how professional wrestlers,

circus acrobats, and Olympic athletes get strong

muscles? Well, it has a lot to do with the nutrient

protein, which builds their muscles. Protein is a

nutrient that's naturally found in plants and animals.

It's made of microscopic building blocks called

amino acids. When you look at amino acids under

a microscope, they look like tangled strings.

 

Protein is an important and necessary part of your daily meals to help you to grow and stay healthy. (Obtained from Study.com) 

 

In this class, we will study where in food and the body we can find proteins, some important proteins in the body, and how to supply them when a person decides to become vegetarian.

​

​

1. Copy the following protein ID in the notebook and complete the information using the  Britannica Kids and PrimaryLeap websites:

​

​

​

​

​

​

 

 

 

2. Draw 5 foods high in protein

​

3. Which parts of the human

body contain most of the protein?

​

​

4. Choose TWO of these proteins and investigate what is their function in the body:

​

       Collagen                                             Thrombin                                      Hemoglobin

​

                                      Insulin                                                  Oxytocin

​

       Histones                                           Immunoglobin                                 Ferritin

​

                                Amylase                                                        Lysozyme

​

 

5. Visit the Eating well website and write some

of the foods that vegetarian people can consume

in order to replace animal protein

​

6. Read the whole PrimaryLeap website and solve the interactive worksheet you will find below, let's see how much you have learnt!

Fats, just like carbohydrates, are made up of carbon, hydrogen, and oxygen. These nutrients are also essential for having good health. 

​

Did you know that the cell membrane is made of fats? it is made of two layers of a special type of fat called phospholipid:

​

​

​

​

Today we will learn more about the types of fat and where to obtain them. Let's begin with this simple video:

​

Let's solve some activities in the notebook:

 

​

​

​

​

1. Go to the Byjus website and complete this information:

​

a) Mention 2 functions of the fat in our body

​

b) According to the types of fats shown in the site, complete this table:

​

​

​

​

​

2) With a partner, share your answers to the following questions. Then, go out and apply the survey to different people while recording their answers:

​

​

​

​

​

​

​

 

3) Classify the foods you find in the laboratory according to: (write them in increasing order, write the percentages and grams)

​

a) Carbohydrates (grams)

b) Protein (grams)

c) Fat (grams)

d) Number of minerals and vitamins

(vitamin A, B, C, D ...etc and minerals like iron, calcium, zinc, etc.) Write the ones each food has.
