UNIT 1- THE HUMAN BODY

-Body parts

Human beings are animals, but they are different from other animals because we can think and we can talk.

Our body consists of three parts: the head, the torso (trunk) and the limbs.

- Vital Functions

Human beings are living things. They do the three life processes:

  • Nutrition 
  • Reproduction 
  • Interaction

-The Stages of Life

The human body changes over time. We can divide our life into five stages:

  • Childhood
  • Adolesce
  • Young adulthood
  • Adulthood
  • Old ages 

- Musculoskeletal System

Musculoskeletal system consists of the skeleton (bones), joints and muscles. It helps us to move the different parts of our bodies.

-Our Senses

Our sensory organs perceive information from outside. The senses are: sight, hearing, smell, touch and taste.

  • Eyes are the organs of sight.
  • The ear is the organ of hearing.
  • The nose is the organ of smell.
  • The tongue is the organ of taste.
  • The skin is the organ of touch.

UNIT 2- EAT WELL, FEEL GOOD
-Digestive System
The digestive system consists of a group of organs that work together to help us digest the food we eat.

-Nutrition
Food is everything we eat and it allows us to grow and stay healthy. Food comes from different sources: animals, plants and minerals.
Food contains substances that we need to live and grow. These substances are called nutrients.
We classify food into groups according to the nutrients they contain:
-Carbohydrates
-Fats
-Water
-Vitamins and Minerals
-Proteins
-Calcium (Dairy)


- Nutrition Song
Our diet is what we eat everyday. For a balance diet, we have to eat the right amount of foods from all the food groups.

UNIT 3-  ANIMALS
Animals are living things. They do the three life processes of nutrition, reproduction and interaction.

-Nutrition
All animals need to eat to get the energy to move, grow and reproduce:
  • Herbivores eat plants.
  • Carnivores eat meat from the other animals.
  • Omnivores eat plants and meat.


-Reproduction:
  • Viviparous: animals that develop inside their mother's womb.
  • Oviparous: animals that develop inside an egg. 

-Interaction:
Animals interact with their environment using their senses, their muskuloskeletal system and their nervous system.
