In that photo,  Mr. Fabien, Our ESL teacher asked us to watch a film named ‘Home’. Then, Mr. Fabien will give us  some question about that film. So, we have to listen clearly. This film was telling a story about our 'Home' (Earth) in a few years ago. 

Art

In Art lesson, we've learn about the dark-light technique, how to make a 3D cube and a cube. I didn't think my painting is good. Because, start from I was in elementary my drawing is always simple and my painting isn't very neat. But, even it's not very good I'm proud of it. So, here is some picture that I draw and paint myself.

This is my 3D drawing and painting

ICT

Do you know...?

•          How to differentiating various communication device (old and new)

Communication is an information delivering process (message, news, idea, or opinion) from one side to another. In the ways of human to communicate always experience a development along with the development of the human’s knowledge itself.  Here is the history of communication course from the old times up to now.

1.    Various tribes in Africa used a sound of wooden drum to send the message

2.    The American native people used smoke to send the message that can be seen in several miles away.

3.    In the 18^th century, the wooden barriers on the high pole in French along the country sending a signal up to hundreds of kilometers away.

4.    Claude Chappe invented a semaphore system in 1797 and now it still being used by Navy to send message among the ships. On this left side are the pictures of semaphore.

5.    In 1838, an American called Samuel Morse invented a code in the form of long and short flashes of electric current lamp which is usually called in a term of ‘period’ and ‘line’. This code can send message through wire or light flash.

6.    Around 1870s, a Scotland – Alexander Graham Bell invented a telephone. The working principles of the telephone to change the sound becoming an electric signal which is sent to the receiver device hold by the other user. In 15 years period, there are almost some 140.000 telephone users in USA.

7.    An Italian named Guglielmo Marconi invented a radio or wireless electronic device in 1899. Radio station sends the signal through invisible radio wave, and then it is received by antenna. A Scotland – John Logie Baird invented a television in early 1926. The picture on the television can spread through the air or wire. The wave is caught through the air while the installation of cable TV uses a connection device.

 

8.    Nowadays, using cell phone you can talk with anyone practically wherever you are. Your voice is brought by radio wave which is called a micro wave passing one antenna to another; it reaches the telephone you connect it. Some antennas are in the outer space satellite.

2.    Several devices of ICT?

Information and communication devices are media of technology that can be used to deliver the information. The devices of information are now very progressive. It is proved that all of the human activities can be helped with devices like cell phone for having a communication with each other even in a far place,

 Computer is used to get information, and many more. Here are some several devices of ICT.

-Cell phone

Cell phone is a device used to communicate through audio wave and also being used to send message.

Computer

A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. And we can search for information through the internet in computer

   

PE Lesson

A few weeks ago, we've learned about gymnastics. We were divided into groups and we were ask by our teacher to choose two picture of gymnastics and try to demonstrate the actions that are on the pictures. My weakness in the assessment is on the "cat wheels" even if in the assessment we were allowed to not do the action that we could not do. But, I feel unsatisfied. And the handstand was very difficult too. we have to stand with our head on the bottom, and our feet on the top. like my friend did in the picture.  

This is the picture of I and some of my friend were having a practice for the assessment on gymnastics.

We were demonstrating "bridge" or in Indonesia we call it "kayang".

But, even if the assessment wasn't as I've expected to be easy, but I'm proud about what I did. I hope I could do better next time.

After School Activity (ASA)

After school activity (ASA) is a lesson that we can pick ourselves. It depends on what we like. If we like science, then we can pick Science club. For me, I pick 2 After School Activity. It is "Science Club" and "Swimming Club".

In Science Club, there was a view things that we've done. First, we were memorizing the biology language. that wasn't easy to memorize.. Something like solanum lycorpersicum stands for tomato. and many more. After that, we were using the microscope to investigate the cells in an onion. And we also learned to dissect goldfish. We were dissecting the fish to see the body parts of that fish. And the last is, we were watching the "putri malu" plant. To see the effect of different ways we make the plants close the leaves. And the very last thing is, we watch the explanation of our friend. They were explaining about the project that they're been doing. They're making a balloon blow it self because of the chemicals.

In Swimming Club, we learned about the breast stroke. And how to use it as fast as you can.  I know, I'm not so good in swimming.  But, at least I already know how to swim. Every Wednesday, we practice to swim faster and faster. Because you know, "practice make perfect".  

Toxic

Toxic is one of the hazard symbol. In the science lesson, we can mention that the toxic symbol or the poison symbol is an important symbol. Notably, this symbol is very important when we are in a laboratory specially science laboratory. This symbol warns us to be wary of the chemicals. We should have careless when holding chemicals. We have to take this symbol serious because, if we are exposed to the chemicals we’re going to get hurt. So, if you are exposed to chemicals, you must immediately report to your teacher or an older person (only in science laboratory).

This symbol also has another function than in a lesson. This symbol also has a function to our lives. If we do not have this symbol, maybe we'll have a lot of diseases specially skin diseases. Or we could even die.

Music Reflection

A few days ago, we’ve learn about pentatonic melody. Pentatonic melody is 10 tones in two or three line of music. In this pentatonic melody work, I and my friends make the lyrics too. The lyrics was made by ourselves. This topic makes me improve about finding words by myself that I’m going to use as the lyric of my pentatonic melody. It also makes me improve my ability to draw and find the tone that I’m going to use as my pentatonic melody. Actually, we can say that the pentatonic melody is a very short song. Because, the pentatonic melody has some tone and some lyrics. We can’t say that the pentatonic melody is a song. Because, it is very short and it hasn’t have what is it got to be a song. 

Math Reflection

 1st Chapter Assessment

My feeling for the score in mathematics was quite good. Even if my score isn't very good. But, I am proud about the score that I get. I hope I will have a better score and could answer the wrong answer with the right answer. I’m so happy when Ms. May said that she will give us a chance to get a better score. So, when the second assessment come, I had to be ready. Because Ms. May said, that she will take the highest score. So, I have to get a higher score than the first assessment.

My weakness is in the problem solving. I should practice hard on it. And my other weakness is in the question. So, I had to learn how to analyze the question. Because, If I didn’t understand the question, I could answer it wrong again. I hope that will never happen. Because I want to get the higher score. Not the lower score. I think everyone wants to get the higher score.

Ciri-Ciri Makhluk Hidup

 ● Bernapas
  Ciri utama makhluk dikatakan hidup yaitu bernapas. Ketika bernapas makhluk hidup menghirup oksigen (O2) dan menghembuskan karbon dioksida (CO2). Oksigen diperlukan untuk proses oksidasi zat makanan yang menghasilkan energi dan karbon dioksida. Energi berguna untuk menjalankan kegiatan hidup.

Reaksi oksidasinya sebagai berikut :
Zat makanan + oksigen —> energi + uap air + karbon dioksida.

● Bergerak
Ada dua macam gerak yaitu gerak aktif dan gerak pasif. Gerak aktif adalah gerak berpindah tempat misalnya dengan kaki, sayap dan sirip. Gerak pasif misalnya ditunjukkan oleh tumbuhan. Tumbuhan tidak dapat berpindah tempat, tetapi menggerakkan sebagaian tubuhnya.

Contohnya gerak daun menguncup, gerak batang menghadap cahaya, gerak akar mendekati sumber air serta gerak mekarnya bunga.

● Peka terhadap Rangsang
Makhluk hidup peka terhadap perubahan yang terjadi disekitarnya. Alat pengenal lingkungan pada manusia dan hewan berupa indra. Indra peka terhadap rangsang. Rangsang dapat berupa cahaya, bunyi, bau, rasa atau sentuhan.

Dengan adanya indra yang peka terhadap rangsang-rangsang tersebut, manusia dan hewan mempunyai kemampuan melihat, mendengar, mencium, mengecap rasa dan menyentuh/meraba.
Tumbuhan tidak mempunyai alat indra, tetapi peka terhadap rangsang. Misalnya tumbuhan putri malu menguncupkan daunnya jika disentuh dan pertumbuhan batang kearah cahaya matahari.

● Makan

Makanan diperlukan oleh makhluk hidup sebagai sumber energi, untuk pertumbuhan dan mengganti sel-sel yang rusak. Tumbuhan hijau memperoleh makanan dengan memproduksi sendiri. Tumbuhan hijau sebagai produsen mengolah zat-zat anorganik menjadi zat organik melalui proses fotosintesis.

Fotosintesis adalah proses pembuatan makanan oleh tumbuhan hijau dengan bantuan cahaya.
Tumbuhan tak berhijau daun, hewan dan manusia tidak dapat membuat makanan sendiri. Mereka memanfaatkan makanan dari hasil fotosintesis tumbuhan hijau dan sumber lain dari hewan dan alam.

● Mengeluarkan Zat Sisa

 Dalam proses penyerapan makanan, terbentuklah zat sisa yang merupakan zat yang tidak terserap oleh tubuh. Zat-zat itu disebut zat sisa oksidasi biologis, misalnya air dan karbon dioksida.Berdasarkan aktivitas tubuh dan hasilnya, pengeluaran zat-zat sisa dibedakan atas 3 jenis yaitu, Ekskresi, Respirasi, dan Defekasi.

• Ekskresi, merupakan pengeluaran zat-zat sisa yang dilakukan oleh kulit dan ginjal. Kulit akan mengeluarkan zat sisa yang dinamakan keringat karena adanya kelenjar keringat di bawah kulit. Ginjal akan menyaring darah dan mengeluarkan zat sisa yang disebut urine.

• Respirasi, merupakan pengeluaran CO2 sebagai zat sisa proses respirasi yang dikeluarkan melalui hidung.

• Defekasi, merupakan pengeluaran zat sisa pencernaan makanan yang berupa tinja (feses) melalui anus.

● Tumbuh
Makhluk hidup mengalami pertumbuhan dan perkembangan. Pertumbuhan meliputi perubahan ukuran tubuh, yaitu luas, tinggi dan berat. Perkembangan adalah perubahan menjadi dewasa.

● Berkembang Biak
Makhluk hidup berkembang biak untuk menghasilkan keturunan. Cara perkembangbiakan makhluk hidup berbeda-beda. Hewan berkembang biak antara lain dengan melahirkan, bertelur, bertelur-melahirkan, bertunas, fragmentasi atau membelah diri. Tumbuhan berkembang biak secara alami dan buatan.

Perkembangbiakan alami pada tumbuhan yaitu dengan biji (kawin) dan dengan tidak kawin, misalnya membelah diri, spora, tunas, umbi, geragih, dll. Perkembangbikan tumbuhan secara buatan, misalnya stek, cangkok, runduk dan kultur jaringan.

● Beradaptasi
Makhluk hidup mampu beradaptasi dengan lingkungan. Jenis adaptasi makhluk hidup ada 3. Adaptasi morfologi, adaptasi tingkah laku, dan adaptasi fisiologi.

Adaptasi morfologi adalah penyesuaian terhadap lingkungan yang berhubungan dengan bentuk tubuh atau alat tubuh. Contoh pada katak dan itik terdapat selapu renang pada kakinya untuk berenang.
 
Adaptasi tingkah laku adalah penyesuaian terhadap lingkungan dalam bentuk tingkah laku. Contoh : hewan bermigrasi ke lain tempat yang banyak sumber makanan.
 
Adaptasi fisiologi adalah penyesuaian terhadap lingkungan dalam bentuk tingkah laku. Contoh : berkeringat saat cuaca panas.
