Sources of Light

LIGHT_Reflection and Refraction

REFRACTION 

When  light goes from air to water and its direction changes.

REFLECTION

When light hits an object and the rays reflect in the same direction.

HOW DO WE SEE COLOURS?

If an object looks green, it is absorbing every colour except green. The colour we see is the colour reflected.

ENERGY

Why some objects float and others sink?

The bracelet sinks because it has bigger density than water.
The ball floats because it has lower density than water.

SUMMARY. Here you have the summary we did alltogether last day in class:

Cancer makes the cells grow uncontrollably. 

Eating fast food often and little exercise can cause weigh problems and heart disease. 

Mental diseases, such as Alzheimer's disease affect the nervous system.

UNIT 1 HEALTY HABITS: INFECTIOUS AND NON-INFECTIOUS DISEASES

Some diseases such as colds are contagious. This means they can be transmitted from one person to another. Pathogens enter the body through the nose and mouth.

UNIT 1 NUTRITION_ THE RESPIRATORY SYSTEM

INHALATION

- We breathe in oxygen.
-The diaphragm, the big muscle under the lungs, contracts.
-The ribs expand.

EXHALATION

- We breathe out carbon dioxide.
- The ribs and diaphragm relax.

UNIT 1 NUTRITION_THE EXCRETORY SYSTEM

THE EXCRETORY SYSTEM

The excretory system consists of the urinary system and sweat glands.

1.     What two waste products are excreted by our body?

Urine and sweat are excreted by our body.

2.     What is the function of the renal arteries?

The renal arteries carry blood to the kidneys

3.     Which organs eliminate waste from the blood?

Kidneys eliminate waste from the blood.

4.     Which tubes connect the kidneys to the bladder?

Ureters connect the kidneys to the bladder.

5.     How is the bladder emptied?

The bladder is emptied by another tube called urethra.

v Use your answers to summarize in 5 lines the whole text about the excretory system.

Urine and sweat are excreted by our body.

The renal arteries carry blood to the kidneys. 
They (kidneys) eliminate waste from the blood. 
Ureters connect the kidneys to the bladder.

The bladder is emptied by another tube called urethra.

UNIT 1 NUTRITION: CIRCULATORY SYSTEM

The main organ is the heart.
It (the heart),sends* oxygen and nutrients to our cells.

SECOND TERM_Unit1_NUTRITION: Digestive System

Digestion:

1. The sense of smell provokes the production of saliva in the mouth.

2. We swallow* the food into the oesophagus, a tube that links* the throat with the stomach.

3. The stomach breaks down* food excreting gastric juices.

4. The food becomes a liquid and mixes with bile (produced by the liver) and pancreatic juices. Nutrients are absorbed into the blood*.

5. The waste* passes to the large intestine. Water is absorbed into the blood. Solid waste leaves the body through the anus.

*to swallow: to take food or liquid down the throat

to link: to join or to connect

to break down: to disintegrate a substance 

blood: red liquid that flows throughout the body

wastes: garbage, excrements
