1. Cut and form the Digestive System

11

As you feed the body, what happens to the food?

Food breaks down as it travels through the digestive system, thanks to digestive juices that also help transform it into nutrients. Glands on the tongue make spit to ease food down the esophagus. The stomach releases strong gastric acids that mix and mash food even more (these acids are so powerful the stomach has a lining to protect itself!). When food molecules reach the small intestine, bile from the liver and enzymes from the pancreas break down proteins, fats, and carbohydrates into nutrients that the body can absorb. Bile also helps carry away waste into the large intestine.

1.3.2 Respiratory System

13

1. Label the Respiratory System

14

Swipe the legs. What happens in the respiratory system during exercise?

To get energy to run, jump, or dance, cells in the body use oxygen to burn sugars and starches from food. Carbon dioxide is created as a waste product of this process. When the brain recognizes the increase in CO2, it makes you breathe faster to exhale and get rid of it. The respiratory system picks up the slack to support this exchange of oxygen and CO2.

2. Complete the following chart with information of the Respiratory System

1.3.3 Circulatory System

What is blood made of?

Blood is made up of three kinds of cells: red blood cells, white blood cells, and platelets. They are suspended in plasma, a yellowish fluid that’s mostly (90%) water, but also contains and delivers nutrients, proteins, and hormones to the body. Plasma also picks up waste products and carries them away as blood circulates through the blood vessels.

Blood cells are tiny-but-mighty fighters for your health. Every single drop of blood holds 250 mil- lion red blood cells which carry vital oxygen to every cell in your body. Platelets help heal wounds on the skin and in blood vessels, gathering to stop the leak of blood by clotting. On the skin, they form a scab. White blood cells attack unwanted bacteria and viruses.

1.3.4 Excretory System

1. Complete the next questions with the correct Excretory System vocabulary word

19

2. Color the Excretory System follow the instructions

The kidneys are blood cleaners. Every minute, the heart pumps about one liter of blood through the renal artery and into a network of capillaries. In the kidneys, over one million tiny nephrons, the capillaries and

intertwining tubes that provide exits for waste products, filter the blood.

While clean, toxin-free blood is sent back to the heart through the renal vein, the toxins must find their own way out. Urochrome, a yellow-colored byproduct of the filtering process, combines with the waste materials and water to make urine that swishes through the urinary tract.

Although two kidneys are useful, we only need one to do all this work. Every day, these bean- shaped organs produce about one to two liters of pee in a rainbow of yellows. It’s important to keep the kidneys

working properly drinking plenty of fluids helps.

1.3.6 Causes of Illnesses in an organism´s systems

1. Illnesses in Digestive System

Drag different foods and feed the body. ¿How does the body respond?

Different foods affect the body, well—differently. Eating a balanced diet with a range of foods supports the body’s functions and likewise supports good health. Fruits and vegetables are great sources of vitamins and minerals that help the body grow, develop, and boost the immune system to fight off illness and infection. Dairy products, like milk and cheese, contain calcium to help grow and maintain strong bones. Meats can be a good source of protein and help to build muscle. Grains, like bread and rice, contain fiber, which helps keep the intestines healthy by moving food through the digestive system and causing regular bowel movements, aka good poops.

2. Illnesses in Respiratory System

24

Diseases and conditions of the respiratory system fall into two categories: Infections, such as influenza, bacterial pneumonia and enterovirus respiratory virus, and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD).

3. Illnesses in Circulatory System

A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw.

25

4. Illnesses in Excretory System

1. Copy and draw the kidneys below, try to make them the same as possible

Diseases that affect the excretory system are nephritis, uraemia, kidney stone, polyuria, anuria, oedema, etc. These diseases are not fatal if diagnosed and treated early. A healthy lifestyle can also prevent most of these diseases. Renal failure is when kidneys struggle to process urine via glomerular filtration. It is further categorised into two types, acute and chronic. In the case of ARF, kidney suddenly stops working, whereas in case CRF kidneys lose their abilities gradually over time.

1.5 The Sun as the Earth´s energy source

1. Read the following story tale with one class mate and share your thoughts

Playing with the Sun There was once a forest where all the animals played happily and contentedly together. So much so, that the sun noticed them and wanted to join in. The animals told the sun he could play with them, but when the sun left his place in the sky, and came down to the forest, none of the animals could stand the heat, and they all went running to hide. The sun went back up into the clouds, feeling terribly sad. So sad, that no longer did he want to come out every day and light up the world. Without the sun, life was beginning to run down, the lovely forest and its animals included. Knowing what the problem was, the animals had a meeting to think of ways to cheer the sun up. Someone suggested that they play with the sun at night when he no longer shone. That would avoid the heat of his rays. So that's what they did. All the animals had to make a great effort to rest during the day, so that they could play at night. But they so wanted to cheer the sun up that all the animals managed it. Soon the sun and with it, happiness, returned to the forest and to the rest of the world.

36

Solar radiation is the sunlight and energy that comes from the sun.

Solar radiation travels to Earth in the form of light waves, which are also known as the electromagnetic spectrum. Light waves come in different forms, travel, vibrate, and have different lengths. Some light waves have low energy and are longer. Other light waves have very high energy and are shorter in length. All light waves are electromagnetic, which means that they contain vibrating electric currents and

magnetism.

e. Climate Change

¿What is climate?

When we talk about climate, the first thing that usually comes to mind is the temperature in an area.

Africa typically has a high temperature and therefore, we think of it as having a hot climate. Antarctica is

usually cold so it has a cold climate. Climate is BIGGER though. Climate is an area’s “average weather”,

including temperature, precipitation (rain, snow, etc.), humidity, wind and even seasons (What is climate

change?, n.d.). The Earth has been around a long time and its climate has changed a lot. During the time

of the dinosaurs, Earth was a much warmer place and just

about 10,000 years ago, we finished an ice age. The

problem we face now is human-made climate change.

What we are doing is changing our climate much faster

than Nature intended and that's what’s causing the

problems.

Happy Thought!

It’s not too late! By making small changes to our lifestyles, we can lower our carbon dioxide

emissions and reduce pollution. If everyone does his or her part, we can stop this.

55

¿What’s the big deal with Climate Change?

NASA has reported a global average temperature increase of 1.4° Fahrenheit since the 1880s, and stated

that nine out of the ten warmest years have happened since the year 2000. These records date back 134-

years (Global Climate Change, n.d.).

1. Read and paint the effects of Climate Change

Interesting Fact ¿How can we stop climate change? ……………………………………………….……………………………………………….……………………………………

56

The Greenhouse Effect

One of the most significant ways we affect our environment is the large amount of greenhouse gases we emit,

mainly carbon dioxide (CO2). How does this create global warming

and climate change? It all comes down to the greenhouse effect.

The greenhouse effect is when the layer of gases in the

atmosphere absorbs heat from the Earth to keep it warm like a

blanket or sweater keeps you warm. The gases that do this

(including carbon dioxide) are called greenhouse gases. They are

very important, without them, most places on Earth would be too

cold to live in. But when there’s too many of them, it can cause the surface temperature of the Earth to rise.

2. Elaborate a letter for the world, show them why it is important to take care of our Earth
