NATURAL SCIENCE

UNIT 6. TOOLS AND MACHINES

The test will be next MONDAY 24TH May

Discoveries are things that we find. 

Inventions are things that we make and that didn´t exit before.

Machines make work easier and they can help us to move objects.

There are:

Simple machines: have 1 or 2 parts.

Complex machines: more than 2 parts.

UNIT 5. MATTER AND MATERIALS

The test will be next Monday 26th April.

They need to know:

The difference between natural and man-made materials and some examples.

The properties of materials: examples of each

Difference between float and sink and materials.

Definition of mass and volume

Difference between homogeneous and heterogeneous mixtures.

States of matter: solid, liquid and gas.

Uses of materials.

NATURAL AND MAN MADE MATERIALS

Natural materials come from plants, animals or the ground.

For example:

Stones come from the ground

Wood and cotton come from plants.

Wool come from an animal.

Man made materials are made by humans. They don´t come from the nature.

For example: bricks, metal, glass, plastic....

PROPERTIES OF MATERIALS

• Soft
• Rigid
• Flexible
• Rigid
• Transparent
• Opaque
• Magnetic
• Waterproof

Cotton is soft.

Metal is magnetic

Wood is rigid

Plastic is flexible.

Glass is transparent

Stones are hard.

Plastic is waterproof.

Paper is opaque.

FLOAT or SINK

MASS AND VOLUME

Mass is the amount of matter an object has.

Volume is the space an object occupies.

MIXTURES

In homogeneous mixtures we can´t see the ingredients.

    Examples: milk and chocolate, water and salt...

In heterogeneous mixtures we can see the ingredients.

    Examples: pizza, salad...

UNIT 4. PLANTS

Plants need: water, sunlight, soil and air to live.

Parts of a plant:

Roots: are underground. They absorb water and minerals.

Stem: hold the plant.

Leaves: are green and they make their food here in the leaves. plants breathe through the leaves too.

Flower: is the colorful part of the plant. They make the seed.

Seed: is underground is where the plant grows.

TYPES OF PLANTS

• TREES: have a thick and hard stem called TRUNK.
• BUSHES: have a lot of stems. They are short.
• GRASSES: are thin and bendy.

TREES

Trees are tall. They have a thick and hard stem called TRUNK.

Some trees have fruits and flowers.

PARTS OF A TREE:

• ROOTS
• TRUNK
• LEAVES
• FRUITS
• BRANCHES

TYPES OF TREES

Trees can be:

• Evergreen trees: they are green all year round.
• Deciduous trees: lose their leaves in autumn.

Parts of a flower:

Pistil

Stamen

Sepal

Petal

Flowers make seeds. Seeds make new plants.

Some flowers turn into fruits. The fruit contains the seed. When the fruit falls to the ground new plants grow from the seed.

NON-FLOWERING PLANTS

Mosses and ferns are non flowering plants.

Mosses are short and soft. They don't have flowers. They can’t make seeds.They reproduce with spores.

Ferns are small and green. They live in shady places. They have roots, stem and leaves.They don't have flowers or fruits.

UNIT3. ANIMALS

The TEST will be next Tuesday 2nd February 2021

They have to know the difference between:

• Vertebrates and invertebrates
• Oviparous and viviparous
• Carnivores, herbivores and omnivores.

Types of vertebrates: mammals, birds, fish, amphibians and reptiles.

Types of invertebrates: molluscs, arthropods and worms.

They need to study the 5 types of vertebrates

Tuesday 19th January 2020

VERTEBRATES

Vertebrates have a backbone.

 Mammals, birds, reptiles, amphibians and fish are vertebrates. 

Mammals are viviparous. They have their body covered with fur. 

Examples: dog, cat, lion,tiger...

And also the whale, the bat and the dolphin.

Birds are oviparous. They have feathers. Most birds can fly because they have wings.

Examples: penguin, hen, parrot, chicken...

Fish: they are oviparous. They have scales. They can swim because they have fins. They live in water.

Examples: sardine, trout, shark...

Reptiles are oviparous. They have scales. They can slither.

Examples: crocodile, snake, turtle...

Amphibians are oviparous. The have wet skin. They live in land and in water.

Examples: frog, toad, salamander...

INVERTEBRATES 

Invertebrates haven’t got bones.

Monday 18th January STORY TIME!

Today we are going to listen and watch the STORY.

You need to go to the DIGITAL BOOK and find Coco´story.

Then you have to complete the activities.

Page 44.

Activity 1. Match the babies with their mothers.

Activity 2. Is a book a living or non living thing?

Page 45

Activity 4. Draw 2 living things and 2 non living things from the story.

Activity 5. Circle YES or NO.

Living and non living things

Animals and plants are living things. 

Animals belong to the Animal Kingdom.

Plants belong to the Plant Kingdom.

ANIMAL KINGDOM: we have all types of animals.

For example: lions, cats, fish, crocodiles, birds, bears, spiders, butterflies, giraffes, frogs...

Animals are classified into: 

• Vertebrates have a backbone inside their bodies.
• Invertebrates don't have a backbone inside their bodies. 

VERTEBRATES

Vertebrates have a backbone.

 Mammals, birds, reptiles, amphibians and fish are vertebrates. 

INVERTEBRATES

Invertebrates haven´t got a backbone.

Insects and spiders are invertebrates.

Many invertebrates are very small. 

Molluscs, arthropods and worms are invertebrates. 

Octopuses and snails are molluscs. 

Spiders and ladybirds are arthropods.

ANIMAL NUTRITION

• Herbivores eat plants. Giraffes eat plants: they are herbivores.
• Carnivores eat other animals. Lions eat meat: they are carnivores.
• Omnivores eat plants and other animals. Bears eat meat and plants: they are omnivores.

UNIT 2. INTERACTION

The test will be next MONDAY 30th November 2020.

They will need to know and to write the muscles, bones and joints. Also they need to know the 5 senses and the organs.

Our LOCOMOTOR SYSTEM is made up of BONES, MUSCLES and JOINTS.

Bones form the skeleton.

Bones are hard and rigid

Bones:

• Skull
• Ribs
• Spine
• Humerus
• Femur
• Hip

Muscles

Muscles are soft and elastic.

• Biceps
• Abdominals
• Pectorals
• Quadriceps
• Calf muscles
• Gluteus

JOINTS

Joints make the skeleton flexible.

Joints help us move.

• Shoulder
• Elbow
• Wrist
• Hip
• Knee
• Ankle

THE SENSES

We have five senses: sight, smell, touch, hearing and taste.

I can see with my eyes.

I can taste with my tongue.

I can smell with my nose.

I can touch with my hands.

I can hear with my ears.

UNIT 1. NUTRITION and REPRODUCTION

The TEST will be next MONDAY 26th October 2020

IMPORTANT: They need to write the parts of the systems.

In this UNIT we are going to learn about:

• the digestive system
• the respiratory system
• the circulatory system
• the excretory system 
• the reproductive system

DIGESTIVE SYSTEM

We need to eat a variety of food every day.  We eat food to obtain nutrients.

Our digestive system has diferent parts: 

• mouth
• esophagus
• stomach 
• intestine.

It is important to eat HEALTHY FOOD.

There are 5 groups of food:

• Potatoes, bread, cereals and pasta.
• Milk and dairy.
• Oil and butter.
• Fruit and vegetables.
• Fish, eggs, meat, beans and pulses.

RESPIRATORY SYSTEM

In the respiratory system we breathe OXYGEN and we breathe out CARBON DIOXIDE.

The respiratory system takes oxygen from the air. It carries oxygen to our lungs.

The parts of the respiratory system are:

Nose

Trachea

Lungs

CIRCULATORY SYSTEM

The circulatory systems sends BLOOD around the body.

Blood carries

The HEART pumps BLOOD.

The blood carries and delivers NUTRIENTS and OXYGEN.

The parts of the circulatory systems are:

HEART

BLOOD VESSELS

EXCRETORY SYSTEM

The EXCRETORY SYSTEM helps to eliminate waste products.

Parts of the excretory system:

Kidneys

Ureters

Bladder

Urethra

REPRODUCTIVE SYSTEM

The reproductive system help us to reproduce (have babies).

Humans are VIVIPAROUS.

Humans grow and change.

Our reproductive system allows us to have babies.

Humans are mammals. 

The fetus grows inside the uterus and it spends nine months inside it. 

The umbilical cord connects the baby to its mother.

With this Power Point Presentation, we are going to review the main contents from 1st Grade.
