-----------------------------------
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.
- VERTEBRATES AND INVERTEBRATES ANIMALS
-Pets Song

UNIT 5- MATTER AND ENERGY
- MATTER
Everything is made of matter. Matter has two properties:
-Mass: the amount of matter an object contains
-Volume: the amount of space an object occupies.
- STATES OF MATTER
Matter has three physical states: solid, liquid and gas.
- MATERIALS
The substances we use to make things are called materials. We can find natural materials, that comes directly from nature or human-made materials, we transform natural materials to make them.
Materials song
- ENERGY
We need energy. Energy is the ability to do work. Energy makes things move and it makes machines go.
Energy can be non-renewable and renewable.
- POLLUTION
We can reduce pollution by:
- Turning off lights in empty rooms.
- Kepping the fridge door closed.
- Turning off electrical devices when not in use.
- Folling the 3Rs: reduce, reuse and recycle.
***************
UNIT 6- MACHINES
Machines are devices that help us do tasks more easily. There are simple machines and compound machines.
- SIMPLE MACHINES
The most common are the lever, the pulley, the inclined plane and the wheel. 
- COMPOUND MACHINES
- Here you have an interesting video about machines:
- MACHINES AND ENERGY
We use modern machines in a lot of everyday activities: at school, at work, at home, in transport and communications, and during the free time.
All machines need energy to work. Machines use various forms of energy, such a mechanical, electrical and chemical energy.

UNIT 7- THE SOLAR SYSTEM
Our Solar System has eight planets, which orbit the Sun (a star). It also has satellites, comets and asteroids.
- PLANETS
The planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
- Planets song
- THE EARTH
- The geosphere: it is the solid part of the planet.
- The hydrosphere: all the water on the planet.
- The atmosphere: it is the layer of air that surrounds the Earth.
- THE MOON
Lunar phases:

UNIT 8- WATER
- ATMOSPHERE
The atmosphere consists of five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
- STATES OF WATER
Water changes state when it gets hotter or colder.
- THE WATER CYCLE
The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection.
- EVERY DROP COUNTS
We use water to drink, cook, wash, clean and water plants.
We must use water responsibly. Doing little things can save a lot of water. You can help too!
