Carbohydrates are commonly associated to "special diet", "getting fat" and many other negative concepts. Still, the truth is that we need them to have energy throughout the day ... of course, just like everything in life all extremes are bad, and ingesting too little or too much of this type of nutrient can affect our health.

​

Today we will learn more about this

nutrient. We will get to know some

examples, how our body uses them

and some fun and interesting facts

about food that is rich in

carbohydrates.

​

​

​

​

1) Watch the study.com video and as you do it, complete the text in your notebook:

​

​

​

​

​

​

​

​

​

​

 

 

2. Pay attention to this short presentation, and take notes in your NB:

​

​

​

​

​

​

 

3. Go to the  GODIGIT website and write the health benefits of eating carbs (just mention the titles). Choose the one you don't understand very clearly and explain it with your own words.

​

4. Visit the BIONINJA website, and under the table "types of Saccharides" find and write in your notebook 2 examples (names) of each type of saccharide. ​

​

5. In the Britannica website find which foods are the healthiest to obtain the carbs from? mention at least 6.

​

6. Read the article about energy drinks and write 3 reasons why drinking regularly this kind of beverage that is high in carbohydrates is harmful to our health, especially for teenagers.

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 activities at the end (the little questionnaire), 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. a) Write 2 important facts from each of the videos about FATS.

​

​​b) Use the information from this INFOGRAPHIC to complete this table about the types of fat:

​

​

​

​

​

​

​

2) Rotate through the 5 stations with food containers or wrappings. In each station choose 1 food and write the number of grams per 100 g of Total carbohydrates, total fat and protein. Then, write the list of vitamins and mineral it contains and their amount in 100 g of product.

 

3) Classify the foods you wrote in the class according to: (write them in increasing order, write the number of 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.

​

4) According to the number of nutrients these foods have, which one is the healthiest and why?

​

5) Which one is the least healthy and why?
