UNIT 10: ENERGY AND FORCES

WHAT IS ENERGY

What is energy? Energy is the ability to do work.
We need energy for everything we do.

TYPES OF ENERGY

There are many different forms of energy:

1. Electrical energy
2. Thermal energy
3. Light energy
4. Kinetic energy
5. Chemical energy
6. Nuclear energy

RENEWABLE AND NON-RENEWABLE ENERGY SOURCES

What is a renewable energy source? A renewable energy source is a source of energy that will never run out.

What is a non-renewable energy source? ...

Remeber: Is it forever???

LIGHT

- Def: Light is a form of energy.

- Light sources: Sun (Natural), Bulb (Man-made) and candles (Man- made).

- Properties: Light travels in all directions, light travels in straight line and light travels very fast.

PROPERTIES OF MATERIALS DEPENDING ON HOW MUCH LIGHT THEY LET THROUGH:

Transparent - Translucent - Opaque

THE COLOURS OF LIGHT

Light looks white, but it is actually made up of seven colours: red, orange, yellow, green, blue, indigo and violet, the colours of the rainbow.

Primary colours: red, green and blue.

Secondary colours: magenta, cyan and yellow

Red plus Blue makes Magenta

Red plus Green makes Yellow

Blue plus Green makes Cyan

UNIT 10: MATERIALS

1. MATERIALS:

  - Natural materials: are found in nature. Ex. wood, leather, cotton, wool and sand.

  - Man-made materials: are made by people. Ex. paper, glass or plastic

Paula! I need your notebook! Sorry:)

2. PROPERTIES OF MATERIALS:

   - Flexible: It doesn't break --> Leather

   - Strong: It can support a lot of weight and force --> Iron

   - Elastic: It can be stretched an it returns to its original shape --> Rubber

   - Light: It does no weigh much --> Aluminium

   - Transparent: Light can pass through it, and you can see through it --> Glass

   - Heat-resistant. It withstands high temperatures --> Steel

   - Waterproof: It doesn't let water pass through --> Plastic

   - Fragile: It breaks easily --> Glass

3. HOW WE USE MATERIALS:

    Some materials are very versatile, they have different uses due to their different properties.

    Ex. Plastics and metals.

4. GREEN MATERIALS

    Green materials are materials that do not pollute the atmosphere and do not take too many resources away from nature. Ex. Bamboo

5. MACHINES

What is a machine? A machine is an object that help us to save time and energy.

How many types of machines are there? There are two types of machines: simple and complex machines.

What is a simple machine? A simple machine is a machine that has no or few moving parts.

What is a complex machine? A complex machine is a machine that has two or more simple machines working together.

Remember, Simple Machines are six: lever, wedge, inclined plane, pulley, secrew and wheel.

• Activity 1
• Puzzle

1. WHAT ARE ECOSYSTEMS? 

An ecosystem is made up of all the living things and non-living things that interact together in a specific place.

• Living things: plants and animals
• Non-living things: all the elements that affect the plants and animals.

Habitat: Places where plants and animals find what they need to survive.

2. FOOD RELATIONSHIPS IN ECOSYSTEMS

• Producers: living things that make their own food. Plants.
• Consumers: living things that eat other living things. Animals

THE NUTRITION PROCESS

NUTRITION is a process and it is related to:

• The digestion: the digestive system.
• The breathing: the respiratory system.
• The blood circulation: the circulatory system.
• The excretion: the excretory system.

THE DIGESTIVE SYSTEM:
· Our body needs nutrients.
· We get nutrients through digestion.
.  Our digestive system transforms food into nutrients.
. The organs of the digestive system are:  mouth, (o)esopahgus, stomach, small intestine, large intestine and anus.

THE RESPIRATORY SYSTEM: 

· Our body needs oxygen: 

· We get oxygen through breathing: 

· Our respiratory system gets oxygen from the air: 

. The organs of the respiratory system are: nose,  trachea, bronchial tubes and lungs.

THE CIRCULATORY SYSTEM: 

· Blood is a very important liquid.

· Blood circulation transports nutrients and oxygen.

. The organs of the circulatory system are: the heart, veins, arteries and capillaries.

WATCH A VIDEO

THE EXCRETORY SYSTEM: 
· Our body needs to eliminate waste.
· We eliminate waste through the excretory system and the skin.
  The organs of the excretory system are: kidneys, ureters, bladder and urethra.

GOOD HABITS FOR OUR BODY:
We should sleep 10 hours every night. 
We should brush our teeth after eating. 
We should have a shower every day. 
We should wash our hands before eating. 
We should drink lots of water.
we should eat fruit and vegetables every day. 
We should eat 5 times a day. 
We should exercise regularly.
We shoud wear warm clothes when it's cold.
We should cover our face when we are coughing.
We should sleep ten hours every night.

SCIENCE: FOOD PYRAMID

Como xa sabedes para ter boa saúde é necesario levar unha dieta sa, variada e equilibrada. A pirámide nutricional axúdanos a saber que tipo de comidas e canta cantidade debemos inxerir a diario.


1. FATS AND OILS GROUP: they are foods like cakes, sweets and butter.
2. DAIRY GROUP: they are foods like milk, cheese and yogurt.
3.MEAT AND BEANS GROUP: they are foods like fish, meat and eggs.
4. VEGETABLES GROUP: they are foods like tomatoes, carrots and beans.
5. FRUITS GROUP: they are foods like oranges, apples and grapes.
6. GRAINS AND CEREALS GROUP: they are foods like rice, pasta and bread.

Na seguinte pirámide ollaredes as porcións diarias necesarias para cada un destes grupos. Canto máis abaixo da pirámide,máis porcións debemos tomar. SERVINGS = PORCIÓNS

FATS: These foods have a lot of sugar. Eat a little.
MEAT: Meat and eggs have proteins. Proteins help children grow. Eat two or three servings a day.
MILK:  Foods from milk group have calcium.
FRUIT AND VEGETABLES: Fruit and vegetables come from plants. Eat four or five servings a day.
GRAINS: Grains give us energy. Eat five or six servings a day.


FOOD GAMES

"MY PLATE" : arrastra cada porción ou alimento ao prato.

 "MATCHING FOOD GROUPS": xogo de memoria sobre os distintos grupos de alimentos.

"HIDDEN FOODS": deberás buscar a comida que che indica dentro de cada grupo de alimentos, deberás estar moi atento cando os pratos queden ao descuberto.

"BALANCED MEALS"
 Entra na cociña e selecciona un menú saudable para cada unha das comidas do día. Cando remates comproba o ben que o fixeches facendo clic en "I think I've finished"
