1.) How do animals stay alive?

Nutrition:

Depending on the food they eat, animals are classified into carnivores, herbivores and omnivores.

• Carnivores: kill other animals and eat them.
  
• Herbivores: eat plants and fruit.
  
• Omnivores: eat everything.
  
• Decomposers: eat dead plants and animals.
  
• Scavengers: eat the remains of dead animals.
  

 

2.) What is sensitivity in animals?

Interaction or sensitivity:

• Animals react to their environment to survive.
• Animals get their food and escape from bigger animals.
• Different animals move in different ways (swim, fly, run).
• They make sounds to communicate.

 

3.) How do animals reproduce?

Reproduction:

 Animals have babies. Depending on the type of reproduction, animals can be:

• Oviparous: animals that are born from eggs.

• Viviparous: animals that are born directly from their mother’s womb.

• Ovoviviparous: the eggs develope inside the mothers body and hatch inside. The, the mother gives birth to them.
  

 

4.) Where do animals live?

 A habitat is a place where animals live. They need 5 things: water, food, air, space and shelter.

 

 

5.) What are vertebrate animals like?

VERTEBRATES:

Animals that have an inner skeleton made up of bones. They have a spine. Most vertebrates have a head, a torso, limbs and a tail.

 

6.) How are vertebrates different?

There are five groups of vertebrates:

 Mammals:

• They have hair or fur. 
• They breathe with lungs.
• They give birth to young live, they feed their babies with milk.
• They live on land, but some are aquatic. But only one mammal can fly! The bat.

Birds:

• Birds have a beak and wings for flying. Their bodies are covered with feathers.
• They breathe with lungs.
• They lay eggs, they are oviparous. Some birds, such as ducks and penguins live in water.

 Reptiles:

• Their skin is covered with scales.
• Reptiles breathe with lungs.
• They live on land, but some are aquatic.
• Reptiles are oviparous, they lay eggs.

Fish:

• Fish have scales and they use fins to swim.
• All fish are aquatic animals, they breathe with gills.
• Fish are oviparous, they lay eggs.

Amphibians:

• Amphibians have moist skin.
• When they are young they breathe with gills, but when they are adults, they develop lungs.
• They can live on land or in water.
• Amphibians are oviparous, they lay their eggs in water.

 

7.) What are invertebrate animals like?

INVERTEBRATES:

Invertebrates do not have a spine. There are many different groups of invertebrates:

0.) Let's remember plants' life processes!

Plants are also living things. Plants have three life processes: nutrition, interaction and reproduction.

Nutrition: plants make their own food. The process of making food is called: PHOTOSYNTHESIS

1. The leaves absorb sunlight and carbon dioxide from the air.

2. Roots absorb minerals and water from the soil.

3. Water and minerals pass through the stem to the leaves.

4. The plant uses the sunlight, the carbon dioxide, the water and the minerals to make food.

5. When plants make food, they make oxygen too and release it to the air. This is good because humans and animals need oxygen to breathe.

Interaction: plants can’t move around. But they can react to their environment by moving their parts. For example:

Reproduction: it is the process by which living things create new living things. Plants also reproduce. Seeds can create a new plant.

1.) What do the parts of a plant do?

Game: http://www.softschools.com/science/plants/plant_parts/

2.) What are seed-producing plants?

There are 2 types:

• Angiosperms: produce flowers, fruit and seeds.
  

• Gymnosperms: produce cones and seeds.
  

3.) How do flowering plants reproduce?

• Stamen: produce pollen.
  

• Pistil: contains the ovary, the ovary transform into a fruit.
  

• Ovary: contains ovules, the ovules transform into seeds.
  

• Petals: colourful to attract insects.
  

• Sepals: small and green. They protect the flower.
  

4.) The life cycle of a flowering plant.

1. Seeds germinate.

2. The plant grows into a tree.

3. The wind, insects or animals transport pollen from the stamen to the pistil.

4. Pollen travels to the ovary and fertilises the ovules. The ovules become seeds and ovary a fruit.

5. Fruit falls into the ground and a new plant grows out of the seeds.

5.) Do all plants produce seeds?

The answer is NOOOOO!!!! Two types of plants do not produce flowers or fruits with seeds:

• Mosses are very small. They grow on rocks, tree trunks or on the ground. They live in moist places. The produce tiny spores in capsules.
  

• Ferns have very big leaves called fronds. They produce spores under the leaves. They live in shady and moist places like forests.

1.) What are nutrients?

 Nutrients help us to grow and repair our body. They keep us healthy and give us energy.

 

2.) The food wheel and the food pyramid.

The food wheel and the food pyramid help us to choose a healthy diet.

We should eat carbohydrates daily: bread, pasta or cereal are good options!

We also should eat fruits and vegetables daily. There are so many to choose from! 

2-3 servings of meat, fish and eggs are fine. 

 

2-3 servings of dairy products are also enough.

We should eat fats, sugars and oils occasionally.

 

 

3.) What is a healthy diet?

A healthy diet helps us to stay healthy. It must be balanced. The Mediterranean diet is the best example of a healthy diet.

4.) What is the digestive system?

It is the system that we use to digest food and absorb nutrients.

Unit 1. The human body.

👂👃👄 Unit 1: The human body 👅💪💀

This unit explains how our body works. It introduces some organs and the body systems they belong to. It explains how our sense organs work and how we control movement.

1.) Nutrition

The process of obtaining energy from food.
There are four body systems involved in nutrition. 

a) Digestive system.

 

b) Circulatory system.

 

c.) Respiratory system.

 

d.) Excretory system.

2.) Body systems.

a.) Reproductive system:

The female reproductive organs are: vagina and ovaries.

The male reproductive organs are: penis and testicles.

b.) Nervous system:

With the five senses, it recognises and respond to what is happening around us. It is made up of the brain, the spinal cord and the nerves.

-The brain controls everything. It receives messages from the five senses and gives instructions.

 

 

-The nerves are connected to the brain by the spinal cord. They carry messages to the brain and instructions from the brain to our body.

 

c.) Locomotor system:

It makes our body move. It is made up of bones, joints and muscles.

- Bones (skeleton) they support the body and protect the heart, lungs and brain.

- Muscles work together with the bones to move the body. 

 3.) The five senses.

Human beings have five senses that help them interact with the world: touch, taste, sight, smell and hearing. Each sense has an organ. 

 

 

The organ of touch is the skin. We use our skin to identify hot or cold, hard or soft, smooth or rough. Our body is covered with skin. It’s the largest organ in the body.

ü The organ of taste is the tongue. We use our tongue to identify different flavours.

 

The organs of sight are the eyes. We use our eyes to identify colour, shape, size and distance.

The organ of smell is the nose, we use our nose to identify different smells.

The organ of hearing are the ears. We use our ears to identify loud and quiet sounds.
