The Cell

All living organisms are composed of cells, some have only one cell and are called unicellular and others have many cells and are known as multicellular. The cell is the smallest part of a living organism.

The cells of both animals and plants have three vital functions: nutrition, relation and reproduction. The cells parts consist of a membrane, the cytoplasm and the organelles, where the nucleus is the cell's most important organelle. The genes are found there as well as the hereditary characteristics of all living organisms. We look so alike our parents because we receive their hereditary genes.

During this educational videos dedicated to Happy Learning children we will see that all living organisms, no matter how big or small, are made up of cells and that all of them are fundamental, imperative for our beautiful life's balance.

Website that explains 5 kingdoms (it uses terms Protist for "Algae and protozoa" and Monera for "Bacteria")

# data[].attributes.attachment_link.readable_text
Kingdoms are groups that categorize all living things, from the tiny bacteria to the large elephant. There are five kingdoms used by scientists: and Each of these kingdoms has specific defining features that help scientists sort living things.

History of the Five Kingdoms

Looking around the natural world, it is easy to see the similarities and differences between living things. Some living things grow out of the ground and don't move, and others are furry and run around.

Over 2,000 years ago a Greek philosopher named Aristotle first decided to split living things into two groups: animals and plants. We now know that there are more ways to distinguish living things, but this was a good place to start.

After Aristotle, scientists spent many years learning more about the living world. They finally decided on the five kingdoms we use today. However, it's important to remember that scientists are always learning new things, so these groups might change in the future.

Classifying the Kingdoms

There are a number of criteria for classifying the different kingdoms. Listed below are the five kingdoms are some of their characterizing features. You can click on each link to learn more about the kingdom.

Animal: Animals are multicellular organisms with eukaryotic cells. This means that the cells have nuclei and organelles. Unlike plants, animals get nutrients by eating - they can't make energy themselves.

Plant: Plants are also multicellular organisms with eukaryotic cells. Unlike animals, most plants cannot move. They can, however, make their own food through a process called photosynthesis.

Protist: Protists are single-celled organisms with eukaryotic cells. Some protists eat to get energy and some use photosynthesis.

Fungi: Fungi are multicellular organisms with eukaryotic cells. Like plants, fungi have cell walls, but they cannot perform photosynthesis and have to absorb nutrients to get energy.

Monera: Monera are single-celled organisms with prokaryotic cells. This means that the cells do not have nuclei or organelles.

Explanation of how a food chain becomes a food web

# data[].attributes.attachment_link.readable_text
Bigger Food Chains

Here's another food chain, with a few more animals. It starts with acorns, which are eaten by mice. The mice are eaten by snakes, and then finally the snakes are eaten by hawks. At each link in the chain, energy is being transferred from one animal to another.

There can be even more links to any food chain. Here another animal is added. It goes

Grass to grasshopper to mouse to snake to hawk.

There is actually even more to this chain. After a hawk dies, fungi (like mushrooms) and other decomposers break down the dead hawk, and turn the remains of the hawk into nutrients, which are released into the soil. The nutrients (plus sun and water) then cause the grass to grow.
It's a full circle of life and energy!!

So food chains make a full circle, and energy is passed from plant to animal to animal to decomposer and back to plant! There can be many links in food chains but not TOO many. If there are too many links, then the animal at the end would not get enough energy.

The heart is about the size of your fist, and you won't believe the things that this very important organ can do. Prepare to be amazed by these cool heart facts.

So, first let's take a look at how this little bit of dynamite that comes in a small package works.

The heart is like a big pump made of muscles, and it constantly pumps blood throughout our bodies every minute of every day. These movements are called 'involuntary' which means you don't actually have to think about making your heart beat; your brain does the work for you and passes on the message.

So everyone thinks that the heart is on the left side of your chest, well it's not. Whoever made that up has fooled people for years, maybe it was a trickster trying to trick us. It's actually right in the middle of your chest between your two lungs. It is protected by your ribs. At least we know it's in a safe spot!

The heart has four chambers, the left and right atrium and the left and right ventricles. Interestingly 'atrium' is the Latin word for entrance hall and 'ventricle' is the Latin word for little belly. So, there's a little belly inside our hearts...interesting.

There are also four valves in the heart, and these are there to make sure that the blood only goes one way, in or out. Imagine the chaos it would cause if the blood was going in and out all at the same time.

So how does the blood get around our bodies? Well when it leaves the heart it gets taken on a journey through arteries. Have you heard of the aorta and the pulmonary artery? Well these are super important for making sure our blood gets to the right place at the right time. It's like a well-timed train.

But what about when the blood needs to go back to the heart. Well here it is carried through veins. If you look at your wrists, you'll probably be able to see veins which look blue from the outside.

Then there's blood that comes from the lungs into the left atrium; this is transported along nicely through the pulmonary veins, while blood that comes from the body goes flowing in through the superior vena cava (this carries blood from your upper body) and inferior vena cava (this carries blood from your lower body).

You must have felt your own heart beating, well this actually works from electricity, yes really, electricity! Your heart contracts, or tightens up and this makes all the chambers smaller and pushes blood back into the blood vessels. So that's how it's done...interesting! When your heart relaxes again, the chambers get bigger and the blood comes back into your heart. Wow, sounds pretty complex.

Interesting and unusual facts about the heart

The heart weighs between 7 and 15 ounces (about 200 to 425 grams) which is about the same as a bottle of Heinz Ketchup! Pick up a bottle of ketchup and you'll be able to feel how much your heart actually weighs.

Now this is quite unbelievable. The average adult heart beats about 72 times a minute, 100,000 times a day and 3,600 times a year. During a person's life their heart could beat more than 3.5 billion, yes 3.5 billion, times.

This amazing bit of body machinery pumps about 100 gallons (380 liters) of blood through your body, every single hour, which is about 2,400 gallons (9000 liters) per day. Man it works hard. That's about the same as 1,600 glasses of water, per hour and 38,400 glasses of water per day. Wow. We certainly wouldn't be able to drink that much water. Now let's work that out over a lifetime...it pumps about 1 million barrels of blood during an average lifetime which would fill three super tankers. Getting the idea of how hard this little fellow works?

Let's look at it in another way. Turn on your kitchen faucet all the way for 45 years and that is the same amount of blood that is pumped through your heart in a lifetime. Okay, don't turn on the faucet; your parents won't be too pleased at all! What a waste of water too.

Want to know how fast the blood pumps through your aorta? It pumps at 1 mile (1.6km's) per hour. That is pretty fast.

You know when you hear the sound of your heartbeat; it's got a kind of 'lub dub' sound. Well that's from your four heart valves closing. What a cool thing to know.

Your heart does the most physical work out of any other muscle in the body. Hardly surprising when you see all the work it's got to do.

All of your blood vessels, which include arteries, veins and capillaries, are over 60,000 miles long (about 97,000km's). If we had to stretch them all out it would go round the world twice. No way. How they all fit in our body who knows.

This is interesting. During a heartbeat the heart creates pressure, okay cool. Now the amount of pressure it creates would be able to make your blood squirt a distance of about 30 feet (9 meters).

In 1967 Dr Christopher Barnard did the first ever successful heart transplant in Cape Town, South Africa. It was a wonder of medicine.

Can you believe there is actually a time and a day when most heart attacks occur? Well it's between 8 and 9am in the morning and Monday is the most popular day. Perhaps we aren't all that keen on Monday.

To keep your heart healthy you really need to get out there and get some exercise in...at least 30 minutes on most days of the week.

Why is the heart always associated with love? Well there are different theories, the Greeks believed the heart was the seat of the spirit, the Chinese associated it with the center for happiness and the Egyptians thought the emotions and intellect arose from the heart. Then Plato came along and believed that we reason through our brains but love came from our heart.

Early Egyptians believed that the heart, and other organs, moved around inside our bodies. Imagine that, we'd never be able to sit still.

Did you know that the heart can continue to beat outside of the body as long as it has got enough oxygen? Well this is because it has its very own electrical impulse. Freaky.

The heart pumps blood to almost all of the 75 trillion cells in our body. The only part of our body that doesn't get blood is the corneas in our eyes. 75 trillion cells, no way.

This is very interesting and very fast too. When your body is at rest it takes 6 seconds for the blood to go from your heart to your lungs and back again, 8 seconds for it to go to your brain and back and 16 seconds for it to go all the way down to your toes and back.

Imagine this. Your heart creates enough energy every single day to drive a truck for 20 miles (32km's). So if you're 10 you would have been able to drive a truck for 73,000 miles (about 118,000km's). Who knows where you'd be now, but you'd have been able to go to the moon and back.

If you own a cat, you're in luck. It can reduce your risk of having a heart attack by more than a third. Think you should ask your parents for a cat if you don't have one, you'll be super healthy.

Did you know that when you listen to music your heartbeat changes and it takes on the same beat as what you're listening to? So when you're listening to super-fast music your heart beats faster and slower when you're listening to calming music. Amazing huh.

This is grim! In 1929, German surgeon Werner Forssmann examined the inside of his own heart. He threaded a catheter into his arm vein and pushed it 20 inches (50cm's) into his heart. But some good did come out of this as he actually invented something called 'cardiac catheterization' - which doctors now use all the time.

Men and women's hearts beat differently. A women's heartbeat is faster than a man's at 78 beats per minute and a man's at 70 beats per minute.

Do you know what an electrocardiograph is? Well it measures the electric current in the heart and helps doctors to know what's happening in this amazing organ. It was invented in 1903.

If you want to feel how fast your heart is beating put your finger on the side of your wrist or throat. This is your pulse. Get the stopwatch out and see how many times it beats in a minute. As a kid it should beat about 75 to 100 times per minute. Go on, check it out now.

When you're running around, or if you're excited, have you noticed that your heart beats faster? Well that's because your heart needs to work even harder than normal to get more blood to your muscles so they're in tip-top shape. Gosh as if it doesn't work hard enough already.

Now we know the heart works hard, but this might shock you. Even when you're resting your heart is still working at an unbelievable pace...twice as hard as the leg muscles of someone that is sprinting. Amazing.

The aorta is almost as thick as a garden hose. On the flip side, your capillaries are so small that it would take ten of them to be as thick as a piece of hair.

This fist-sized piece of our body is a truly amazing little bit of machinery. Oh the places we can go with it...even to the moon and back!

What are senses?

Think about what happens when Mum or Dad tells you that dinner is ready - you can hear them asking you to wash your hands, feel the water and soap against your skin, smell what's cooking, see your chair at the table and taste the food on your plate. You can do all of that thanks to your senses!
Senses allow us to observe and understand the world around us. There are five main ways we can do this: through sight (with our eyes), touch (with our fingers), smell (with our nose), taste (with our tongue) and hearing (with our ears).

The Nervous System

Today we are going to learn about the nervous system...

We all know that humans have five senses, sight, which is the ability to see through our eyes, taste, which we use to enjoy different flavors, smell, which allows us to smell the wonderful scents in flowers, hearing, which we use to listen to our favorite music and touch, which is how we feel tickles or soft caresses through our skin. Well our nervous system is what receives all this information captured by the senses, interprets it and responds to each situation.

The nervous system has special cells called neurons and it is divided into two parts: the central nervous system and the peripheral nervous system.

The central nervous system is made up of the brain and the spinal cord. The skull is where the brain is located, as well as the cerebellum and the brain stem. The brain occupies the largest part of the skull and is in charge of controlling our memory, emotions and voluntary actions such as reading, writing or jumping.
The cerebellum also coordinates our balance as well as our movements. It is because of it that we are not constantly falling down, thank you cerebellum!

The brain stem links the brain to the spinal cord and controls the automatic actions such as our heart beat or the blinking of our eyes, which happens without us even realizing it.
The spinal cord is another part of the central nervous system. It is within our spine and is almost like a highway connecting the brain to all the bodies' nerves. The spinal cord is responsible for all the reflexes, like when you touch something hot, we pull our hand away
instinctively, without even thinking.

The peripheral nervous system is a set of nerves which travel around our body and is divided in two major parts: sensory nerves and musculoskeletal system.

The sensory nerves carry information received by the five senses to the brain; the musculoskeletal system transmits the brain's responses allowing the muscles to perform. So if we were to fall into the water, for example, the automatic system would send a message to our muscles ordering us to swim and get out of the water, thank goodness, because otherwise we would drown.

Well now you know about the nervous system, it's real interesting isn't it?
