Climate Change

CLIMATE CHANGE

Summarized by : Tandri

Earth's climate has a huge impact to human life. 

Climate is a weather that usually happened on certain area regularly.  There are lots of thing that have an effect on the climate. For example : the atmosphere, the oceans, the land, ice, people, plants, animals, light, and heat of the sun. 

atmosphere that is an important for controling the climate is unstable now.

There are too many green house gases that grows. This green house gases are making the temperature of earth become very hot that an ice berg can melt easily.   There are many effects of a warmer world such as heatwaves, flood, and storms. 

Over a million years, climate change over and over. 

There have been an ice age million years ago, ice age is a condition of earth that are covered by ice all over the place. Human cannot live in that condition so thankfully we are born after the ice age. 

Scientist had study that the cause of climate change are not always natural. 

Human are responsible for releasing a bunch number of carbondioxide to the air that made the the green house increasing. 

For the better future , we should lower the activities that can release carbondioxide to the air. 

For example : start using the electrecity rather than oil. In that case, we could suppres the heating so that the earth does not heat overtime and the climate bevome fresher.

All About Puberty

Time to Change

OK, so it's a funny word — but what is puberty, anyway?

Puberty (say: PYOO-ber-tee) is the name for the time when your body begins to develop and change as you move from kid to adult. We're talking about stuff like girls developing breasts and boys starting to look more like men. During puberty, your body will grow faster than at any other time in your life, except for when you were a baby.

It helps to know about the changes that puberty causes before they happen. That way, you know what to expect. It's also important to remember that everybody goes through these changes. No matter where you live, whether you're a boy or a girl, whether you like vanilla or double-fudge-chunk ice cream, you will experience them. No two people are exactly alike, but one thing everyone has in common is that we all go through puberty.

Usually, puberty starts between ages 8 and 13 in girls and ages 9 and 15 in boys. This wide range in ages may help explain why some of your friends still look like young kids whereas others look more like adults.

When your body is ready to begin puberty, your pituitary (say: pih-TOO-uh-ter-ee) gland (a pea-shaped gland located at the bottom of your brain) releases special hormones. Depending on whether you're a boy or a girl, these hormones go to work on different parts of the body.

Changes for Boys and Girls

For boys, the hormones travel through the blood and tell the testes (say: TES-teez), the two egg-shaped glands in the scrotum (the sac that hangs under the penis), to begin making testosterone (say: tess-TAHS-tuh-rone) and sperm. Testosterone is the hormone that causes most of the changes in a boy's body during puberty, and men need sperm to be able to reproduce (be the father of a baby).

In girls, these hormones target the two ovaries (say: OH-vuh-reez), which contain eggs that have been in the girl's body since she was born. The hormones cause the ovaries to start making another hormone, called estrogen. Together, these hormones prepare a girl's body to start her periods and be able to become pregnant someday.

Boys and girls both begin to grow hair under their arms and their pubic areas (on and around the genitals). It starts out looking light and thin. Then, as kids go through puberty, it becomes longer, thicker, heavier, curlier, and darker. Eventually, boys also start to grow hair on their faces.

It's Just a Growth Spurt

A spurt is a short burst of activity or something that happens in a hurry. And a growth spurt is just that: Your body is growing and it's happening really fast!

When you go through puberty, it might seem like your sleeves are always getting shorter and your pants are creeping up your legs. That's because you're having a growth spurt that lasts for about 2 to 3 years. When that growth spurt is at its peak, some kids grow 4 or more inches (10 or more centimeters) in a year! At the end of your growth spurt, you'll have reached your adult height — or just about.

But your height isn't the only thing that changes during puberty.

With all this quick growth, it can seem like one part of your body — your feet, for instance — are growing faster than everything else. This can make you feel clumsy or awkward. This is normal, too! The rest of your body will eventually fill out and shape up, and you'll feel less klutzy.

Taking Shape

Your body also fills out and changes shape during puberty. A boy's shoulders will grow wider and his body will become more muscular. He may notice a bit of breast growth on his chest. Don't worry, this is normal — and it goes away for most boys by the end of puberty.

In addition, boys' voices crack and eventually become deeper, their penises grow longer and wider, and their testes get bigger. All of these changes mean that their bodies are developing as they should during puberty.

Girls' bodies usually become curvier. Their hips get wider and their breasts develop, starting with just a little swelling under the nipples. Sometimes one breast grows more quickly than the other, but most of the time they even out. Girls may start wearing bras around this time, especially if they are involved in sports or exercise classes.

With all this growing and developing going on, some girls may be uncomfortable with how their bodies are changing, but it's unhealthy for girls to diet to try to stop any normal weight gain. If you have any questions about puberty or are worried about your weight, talk to your parent or doctor.

One question a girl will have is: When will I get my first period? This usually happens about 2 years after her breasts start to develop. The menstrual (say: MEN-strul) period, or monthly cycle, is when blood is released through the vagina. That may sound alarming, but it's normal and it signals that a girl is growing up and her body is preparing so that she can have a baby someday.

Here's what's going on: Each of a girl's two ovaries holds thousands of eggs. During the menstrual cycle, an egg is released from one of the ovaries and begins a trip down the fallopian (say: fuh-lo-pee-un) tube to the uterus, also called the womb. A girl has two fallopian tubes, one connecting each ovary to the uterus.

Before the egg even leaves the ovary, though, hormones stimulate the uterus to build up its inner lining with extra blood and tissue. If the egg gets to the uterus and is fertilized by a sperm cell, it may plant itself in that lining and grow into a baby. The extra blood and tissue nourishes and protects the baby as it develops.

But most of the time the egg is only passing through. When the egg doesn't get fertilized, or if the fertilized egg doesn't become planted in the lining, the uterus no longer needs the extra blood and tissue, so the blood leaves the body through the vagina. This blood is known as a girl's period. A period usually lasts from 2 to 7 days. About 2 weeks after the last period, a new egg is released as the cycle repeats itself.

Face Up to Changes

Another thing that may come with puberty is acne (say: AK-nee) — or pimples — caused by all those hormones at work in the body.

Skin gets oilier and pimples sometimes start showing up when puberty begins, and you may get them throughout the teenage years. You might see pimples on your face, your upper back, or your upper chest.

To help control pimples, wash your face twice a day with warm water and a mild soap or cleanser. Don't squeeze, pick, or pop your pimples. Your doctor can also offer suggestions for clearing up acne. The good news is that acne usually gets a lot better as you get older.

PERTEMUAN KEDUA

Putting the P.U. in Puberty

P.U.! A lot of kids notice that they have a new smell under their arms and in other places when they hit puberty — and it's not a pretty one. That smell is body odor (you may have heard people call it B.O.) and everyone gets it.

As you enter puberty, the puberty hormones stimulate the glands in your skin, including the sweat glands under your arms. When sweat and bacteria on your skin get together, it can smell pretty bad.

So what can you do to feel less stinky? Well, keeping clean can stop you from smelling. You might want to take a shower every day, either in the morning before school or at night before bed. Wearing clean clothes and showering after you've been playing sports or exercising is also a good idea.

Another way to cut down on body odor is to use deodorant. If you use a deodorant with antiperspirant, it will cut down on sweat as well.

There's More?

Boys and girls will also notice other body changes as they enter puberty. Girls sometimes might see and feel white or clear stuff coming from the vagina. This doesn't mean anything is wrong — it's called vaginal discharge and is just another sign hormones are changing your body.

Boys will begin to get erections (this is when the penis fills with blood and becomes hard). Sometimes erections happen when boys think about sexual things or they can happen for no reason at all. Boys also may experience something called nocturnal emissions (or wet dreams). This is when the penis becomes erect when a boy is sleeping and he ejaculates. When a boy ejaculates, semen — the fluid that contains sperm — comes out of the penis. That's why they're called wet dreams — they happen when you're sleeping and your underwear or the bed might be a little wet when you wake up. Wet dreams occur less often as boys move through puberty and they eventually stop.

Change Can Feel Kind of Strange

Just as those hormones change the way your body looks on the outside, they also create changes on the inside. During puberty, you might feel confused or have strong emotions that you've never had before. You might feel overly sensitive or become upset easily.

Some kids lose their tempers more often and get angry with their friends or families. You also may feel anxious about how your changing body looks.

Sometimes it can be hard to deal with all these new emotions. It's important to know that while your body is adjusting to the new hormones, so is your mind. Try to remember that people usually aren't trying to hurt your feelings or upset you on purpose. It might not be your family or friends — it might be your new "puberty brain" trying to adjust.

You might also have sexual feelings that you've never felt before. And you will probably have lots of questions about these new, confusing feelings about sex.

It's easy to feel embarrassed or nervous when talking about sex. It's important to get your questions answered, but you need to be sure you have all the right information. Some kids can talk to their parents about sex and get all their questions answered.

But if you feel funny talking to your parents about sex, there are many other people you can talk to, like your doctor, a school nurse, a teacher, a school counselor, or some other adult you feel comfortable talking with.

Developing Differently

People are all a little different from each other, so it makes sense that they don't all develop in the same way. During puberty, everyone changes at his or her own pace. Maybe some of your friends are getting their period, and you haven't developed breasts yet. Maybe your best friend's voice has changed, and you think you still sound like a kid. Or maybe you're sick of being the tallest girl in your class or the only boy who has to shave.

In a few cases, kids who are developing very early or who are very late in starting have a problem that may need to be checked or treated. If you are concerned about that possibility, talk with your parents and schedule a visit with your doctor. Your doctor knows all about puberty and can help determine if you are developing normally.

But just about everyone catches up eventually, and most differences between you and your friends will even out. Until then, hang in there. Puberty can be quite a wild ride!

Hello my name is Scott number 2, and I want to share my opinion about the presentation before and the subjects this week.

Based on my opinion, the unit about the theme about solas system is very interesting and very useful because we get to know some of the information about the solar system and the universe that we never know about it before.

For me, the presentation before was very good to because we can compare the information from the second presentation with the third one, so its not always the same opinion. 

Thank you

Planet Facts for Kids

Our solar system consists of eight planets which all orbit around our home star, the Sun.

In the image is Jupiter and one of the moons - image taken by the Juno space craft, a NASA space mission

Our planetary system was formed 4.6 billion years ago! 

For most of history it was thought that everything in space moved around the Sun, however around the 17th century the idea, that the earth is just one of the planets in the system, started gaining popularity.

In fact, the Sun is only one of more than 200 billion stars moving about in the Milky Way!

Our solar system consists of eight planets which all orbit around our home star: the Sun.

These eight planets are:

Solar System Facts
What you should know...

Mercury

The closest planet to the Sun is only about as wide as the Atlantic Ocean! 18 Mercuries would fit into the Earth. The planet does not have an atmosphere, just like it is on all the other planets. There is no water present on this dangerous planet either! There temperatures vary between -180°C and 430°C/-290°F and 842°F. 

This is also the fastest planet! It speeds through space with 50km per second/31 miles per second.

The BepiColombo mission was launched in October 2018 and now travels in space towards Mercury which it will reach by 2025. It will orbit the planet to solve mysteries about Mercury. It also will hopefully reveal questions like how planetary systems form. 

Venus

Venus - named after the Roman goddess of beauty - is also known as the evening or morning star. Yellow clouds made of sulfur and sulfuric acid cover the entire planet causing light to reflect off the surface.

This makes Venus the second brightest object in the night sky after the Moon.

Venus - the brightest planet

Venus is very similar to Earth in terms of size and material.

However, it is the hottest planet in the Solar system with temperatures reaching 460°C/480°F. The surface of Venus hosts thousands of volcanoes, craters and super-high mountain ranges.

Many missions have been conducted about Venus but many questions remain. The Soviet Union successfully landed eight space probes on Venus during the 1970s and 1980s.

If the International Space Station is in the sky, it will be brighter and easier to see than Venus! The space station looks like a very bright star! Find out how, where and when you can spot the space station.

Earth

Earth is the fifth largest planet of our solar system and has one large natural satellite, the Moon.

Did you know that all planets were named after Roman and Greek gods and goddesses, except the Earth. The name 'Earth' nevertheless is more than 1,000 years old and means just 'ground'.

Image from Space shows how the Super Typhoon Noru formed

Everything one ever knows is here. This is the only place where life is known to currently exist. Most of the Earth's surface (about 70%) is covered with water.

Mars

Mars, the most likely candidate for a future human habitat, is affected by huge dust storms that occur every now and then and cover the entire planet!

Mars is very cold and dry but water exists in form of ice at the North and South poles. The surface of Mars has many craters, deep valleys and volcanoes.

The largest peak on the red planet is a volcano called Olympus Mons, which is three times higher than Mount Everest, the highest mountain on Earth. 'Mons' is the Latin word for mountain.

Mars - the Red Planet

Mars has two moons called Phobos and Deimos, both are probably asteroids which were caught up by Mars’ gravitational field. 

There are two rovers on the surface of Mars and six spacecraft orbiting Mars that are tasked with discovering the presence of water and searching for evidence of previous ancient life, amongst other things.

Jupiter

Jupiter is the largest planet in the solar system. The most famous feature on the surface of the planet is the 'Great Red Spot' which is actually a storm that has been blowing for about 350 years, if not longer.

Jupiter - true colours as seen by Cassini

Jupiter has some of the largest moons in the solar system and one in particular, Europa might be able to sustain life in an ocean below its icy surface. 

There is one spacecraft currently orbiting Jupiter called Juno. Juno is trying to solve how the planet formed and finding out more about the winds that occur.

Saturn

Saturn is a gas giant just like Jupiter, Neptune and Uranus. This means that it doesn’t really have a proper solid surface as it is mainly made up of gases with a small rocky core.

Saturn is the second largest planet and is known for its rings, although the other gas giants also have these kinds of rings, only Saturn’s rings can be seen the clearest.

Saturn and rings - images by Cassini NASA mission

Saturn’s moon, Titan is the second largest in the solar system.

In 2005, NASA and ESA (European Space Agency) landed a space-probe called 'Huygens' on Titan revealing the composition and the landscape of this moon. This spacecraft was part of the Cassini-Huygens that recently ended when the orbiting spacecraft Cassini was intentionally crashed into Saturn. Cassini showed us that another moon of Saturn, Enceladus is also potentially habitable.

Uranus

Uranus is the second furthest planet from the Sun and therefore also has to travel a pretty long time to go once around out home star. It takes Uranus roughly 84 years to orbit once around the Sun. 

Uranus looks blue because of its gases

Uranus is a blue planet, not because of water, but because of gases that make it appear blue.

Uranus orbits on its side, which means that its seasons are completely different to ours. Summer and winter each take 21 years at the north and south poles!

Neptune

Neptune is closely related to Uranus, the atmosphere is composed of almost the same gases and just like Uranus, Neptune also appears blue. Neptune inherits its name from the Roman god of the sea as reference to its deep blue color.

Neptune is the furthest planet from the Sun and it takes 165 years for Neptune to go once around the Sun.

No space probes have ever visited Neptune or its partner Uranus but a fly-by was made by the space probe Voyager 2 in 1989.
