10 famous figures of chemical scientists:
adapted from: esdikimia.wordpress.com/2011/06/29/10-tokoh-kimia
1. John Dalton (1766 - 1844)
Originator of modern atomic theory which states that matter is composed of atoms that can not be further subdivided. Each
- each element consists of atoms with identical properties and mass,
and compounds are formed when atoms of different elements combine in a
fixed composition.
2. Amadeo Avogadro (1776 - 1856)
An Italian scientist who sparked through hopotesisnya Avogadro's law
that "at the same pressure and temperature, the gases have the same
volume the same number of particles".
3. Humphry Davy (1778 - 1829)
A scientist who succeeded in extracting metals sodium and potassium from hidroksidanya through electrolysis. He is known as a pioneer of electrolysis of the research results.
4. James Prescott Joule (1818 - 1889)
A scientist who formulated the law of conservation of energy, namely "Energy can neither be created nor in musnakan".
5. John Tyndall (1820 - 1893)
An English scientist who proposed the event of light scattering by colloidal particles known as Tyndal effect. Tyndall effect can be used to distinguish sistemkoloid and true solution.
6. Friedrich Kekulé (1829 - 1896)
Chemist
who is known as the ring because it successfully reveals how the six
carbon atoms of benzene molecules bind to the six hydrogen atoms.
7. Sir William Crookes (1829 - 1919)
Scientists
from Britain who argued that merukana cathode ray particles are
negatively charged, has mass, and is owned by all the material.
8. Dmitri Ivanovich Mendeleyev (1834 - 1907)
Russian chemist who created the system based on improved periodek elements' atomic numbers ". this number indicates the number of protons contained in the nucleus of an atom. the number of protons equals the number of electrons surrounding the atom-free.
9. Henri Louis Le Chatelier (1850-19360)
A
French chemist who did research on chemical equilibrium, and present
one of the equilibrium principle is "if the action is something done a
certain equilibrium, then the equilibrium will be shifted to eliminate
the impact of the action".
10.Svante Arrhenius (1859-1927)
A scientist Sweden who got Hadia Nobel Prize for his work on ionization. He
suggested that the compounds in solution can be decomposed into ions
her, and the strength of the acid in solution aqua depending on the
concentration of hydrogen ions in it.

Here are some fun and interesting chemistry facts for you.
- The only elements that are liquid at room temperature are bromine and mercury. However, you can melt gallium by holding a lump in the warmth of your hand.
- Unlike many substances, water expands as it freezes. An ice cube takes up about 9% more volume than the water used to make it.
- If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass.
- There is about 1/2 lb or 250 g of salt (NaCl) in the average adult human body.
- A pure element can take many forms. For example, diamond and graphite both are forms of pure carbon.
- The chemical name for water (H2O) is dihydrogen monoxide.
- The only letter that doesn't appear on the periodic table is J.
- Lightning strikes produce O3, which is ozone, and strengthen the ozone layer of the atmosphere.
- Although oxygen gas is colorless, the liquid and solid forms of oxygen are blue.
- The human body contains enough carbon to provide 'lead' (which is really graphite) for about 9,000 pencils.
- Hydrogen is the most abundant element in the universe, while oxygen is the most abundant element in the earth's atmosphere, crust, and oceans (about 49.5%).
- The rarest naturally-occurring element in the earth's crust may be astatine. The entire crust appears to contain about 28 g of the element.
- Hydrofluoric acid is so corrosive that it will dissolve glass. Although it is corrosive, hydrofluoric acid is considered to be a 'weak acid'.
- One bucket full of water contains more atoms than there are bucketfuls of water in the Atlantic ocean.
- Approximately 20% of the oxygen in the atmosphere was produced by the Amazon rainforest.
- Helium balloons float because helium is lighter than air.
- Bee stings are acidic while wasp stings are alkaline.
- Hot peppers get their heat from a molecule called capsaicin. While the molecule acts as an irritant to mammals, including humans, birds lack the receptor responsible for the effect and are immune to the burning sensation from exposure.
- Dry ice is the solid form of carbon dioxide, CO2.
- Liquid air has a bluish tint, similar to water.
1. This is the last presentation for the subject. this is my turn and my fellow friends from group 9. We had chosen to to share with other the microsoft excel.
2. Up till i manage to complete all assignment and task given in this subject, Overall, i got six assignment. The first one is discussion about the future learning; school in the cloud. the hardest one is our fifth experiment, whereby i had to make my own video for learning resources

Carbon - The Chemical Basis for Life
2. Carbon is a nonmetal that can bond with itself and many other chemical elements,
forming nearly ten million compounds.
3. Elemental carbon can take the form of one of the hardest substances (diamond) or one of
the softest (graphite).
4. Carbon is made in the interiors of stars, though it was not produced in the Big Bang.
5. Carbon compounds have limitless uses. In its elemental form, diamond is a gemstone
and used for drilling/cutting; graphite is used in pencils, as a lubricant, and to protect
against rust; while charcoal is used to remove toxins, tastes, and odors. The isotope
Carbon-14 is used in radiocarbon dating.
6. Carbon has the highest melting/sublimation point of the elements. The melting point of
diamond is ~3550°C, with the sublimation point of carbon around 3800°C.
8. The origin of the name 'carbon' comes from the Latin word carbo, for charcoal. The
German and French words for charoal are similar.
9. Pure carbon is considered non-toxic, although inhalation of fine particles, such as soot,
can damage lung tissue.
10. Carbon is the fourth most abundant element in the universe (hydrogen, helium, and
oxygen are found in higher amounts, by mass).

Our journey in the world of ICT became more exciting. Every week, i found out that myself being more intelligent. i love it.
9. PREZI (Group 8)
Prezi is a presentation tool that helps you organize and share your ideas.
At first glance, Prezi may seem like an inferior example of presentation software. But closer inspection reveals that Prezi is simply so unique, comparing it to traditional slideshow makers . Prezi displays information not as a series of slides, but as one large board that zooms in on specific information or images..
With Prezi, a presentation is created as a whole board. You lay out the information and visual aids however you like, then you create a “path” for the pan-and-zoom functions to follow. The end result? A presentation that starts with one bit of information, zooms out, pans to another bit of information, zooms in, etc. Certainly an interesting alternative to typical slideshow presentation.
You can add text and multimedia items, like photo, video and audio files. There are two cookie-cutter shape options, as well as the word processing ability to do bulleted text. There are also 10 themes to choose from, which include color palates and fonts. You can create your own theme and save it for future use, as well. And there is a form of paragraph style functionality – you can preset three styles and choose from them when you create text blocks.
Want to know more about Prezi, kindly click this link: http://prezi.com/ .
10. Microsoft Power Point (Mouse Mischief )
Very useful while carried out a lesson in a class room. This tool can help teacher to make sure their student are paying attention.
What is it exacly?
Mouse Mischief integrates into Microsoft PowerPoint 2010 and Microsoft Office PowerPoint 2007, letting you insert questions, polls, and drawing activity slides into your lessons.
Students can actively participate in these lessons by using their own mice to click, circle, cross out, or draw answers on the screen.

Microsoft Mouse Mischief is a new free add-on to Microsoft PowerPoint. Mouse Mischief is designed as an inexpensive alternative to clicker-type response systems. Mouse Mischief allows teachers to put multiple choice questions into their PowerPoint slides. Students can then answer the questions using mice connected to their teacher's computer. Mouse Mischief works with both wired and wireless mice. You can learn more and download Mouse Mischief here.
Applications for EducationI have not had a chance to try Mouse Mischief with students yet, but it seems like it could be a good way to get feedback from students during a lesson. If you're school already has Microsoft PowerPoint for teachers, this is a nice free addition for you.

Andai ku terbuang tak diterima
Andai aku disingkirkan
Ke mana harusku bawakan
Ke mana harusku semaikan cinta ini
Andai ku terbuang tak diterima
Andai aku disingkirkan
Ke mana harusku bawakan
Ke mana harusku semaikan cinta ini
Betapa
Di bumi ini ku melangkah
Ke utara selatan timur dan barat
Ku jejaki
Di bumi ini ku melangkah
Ke utara selatan timur dan barat
Ku jejaki
Aku
Bukanlah seorang perwira
Gagah menghunus senjata
Namun hati rela berjuang
Walau dengan cara sendiri
Demi cinta ini
Bukanlah seorang perwira
Gagah menghunus senjata
Namun hati rela berjuang
Walau dengan cara sendiri
Demi cinta ini
[Ulang chorus]
Ku ingin kotakan seribu janji

1. Smiling Makes Us Attractive
We are drawn to people who smile. There is an attraction factor. We want to know a smiling person and figure out what is so good. Frowns, scowls and grimaces all push people away -- but a smile draws them in (avoid these smile aging habits to keep your smile looking great).2. Smiling Changes Our Mood
Next time you are feeling down, try putting on a smile. There's a good chance you mood will change for the better. Smiling can trick the body into helping you change your mood.
3. Smiling Is Contagious
When someone is smiling they lighten up the room, change the moods of others, and make things happier. A smiling person brings happiness with them. Smile lots and you will draw people to you.4. Smiling Relieves Stress
Stress can really show up in our faces. Smiling helps to prevent us from looking tired, worn down, and overwhelmed. When you are stressed, take time to put on a smile. The stress should be reduced and you'll be better able to take action.5. Smiling Boosts Your Immune System
Smiling helps the immune system to work better. When you smile, immune function improves possibly because you are more relaxed. Prevent the flu and colds by smiling.6. Smiling Lowers Your Blood Pressure
When you smile, there is a measurable reduction in your blood pressure. Give it a try if you have a blood pressure monitor at home. Sit for a few minutes, take a reading. Then smile for a minute and take another reading while still smiling. Do you notice a difference?7. Smiling Releases Endorphins, Natural Pain Killers and Serotonin
Studies have shown that smiling releases endorphins, natural pain killers, and serotonin. Together these three make us feel good. Smiling is a natural drug.8. Smiling Lifts the Face and Makes You Look Younger
The muscles we use to smile lift the face, making a person appear younger. Don't go for a face lift, just try smiling your way through the day -- you'll look younger and feel better.9. Smiling Makes You Seem Successful
Smiling people appear more confident, are more likely to be promoted, and more likely to be approached. Put on a smile at meetings and appointments and people will react to you differently.10. Smiling Helps You Stay Positive
Try this test: Smile. Now try to think of something negative without losing the smile. It's hard. When we smile our body is sending the rest of us a message that "Life is Good!" Stay away from depression, stress and worry by smiling.Everyone needs a smile!!!

My friends and i cracking our brain to about what to do in this a
Engage :
A way to improve the students understanding by asking them
to think in a greater depth in order to answer the enhance section. It is
a another method same as the engage but the difference is that enhance is the
application of the knowledge. Students have to relate the scientific concept to
the daily life so that they really understand the topics. They have to think
creatively and critically when answer the question provided
Feel Free To Say Thousand Words
What
is actually engage, empower and enhance?
Engage :
A method that elicit
students's idea from their prior knowledge. Teachers may elicit their ideas
through a few questions so that teachers could know the level of the students
and where should they begin to teach the students. It creates a two ways
communication between teachers and students where students may share their
knowledge besides the teacher does. This engage is the method that used to
attract student's attention. Through the question or picture given, the teacher
will elicit students idea on that particular topic. This enable the teachers to
know about the prior knowledge which the students possesses on the particular
topic.Other than that, engage will help students in the process of think and
give the idea about the question.
Empower :
Empower :
A method where experiment is conducted in a more systematic way and
less time consuming to increase student's knowledge and understanding on
particular topic. Practical is important for them to expose themselves in the
real situation and they understand better about the scientific concepts. In
empower, teachers will prepare some questions from the easiest to the hardest
for the students to answer so that they might empower their knowledge.

MICROSOFT PUBLISHER.
I have learn to use Microsoft publisher. By using this programmer, i would be able to simple brochure, banner for announcement or even create a page for advertisement. During this class, i have to come up with a brochure. In this brochure, i have decide to advertise a free class on how to use chemsketch.
Publisher is included in higher-end editions of Microsoft Office, reflecting Microsoft's emphasis on the application as an easy-to-use and less expensive alternative to the "heavyweights," with a focus on the small business market where firms do not have dedicated design professionals available to make marketing materials and other documents However, it has a relatively small share of the desktop publishing market, which is dominated by Adobe InDesign and QuarkXPress.Publisher has historically been less well liked among high-end commercial print shops, compared with other desktop publishing applications.
5. MICROSOFT PUBLISHER
In Microsoft Office 2007, while most of Microsoft Office apps adopted ribbons in their user interface, Publisher retained its toolbars and did not adopt ribbons until next version, 2010.
Microsoft Publisher includes a library of color schemes you can use to
ensure your publications are well-designed and professional. The
software offers a large selection of "building blocks" that can be
dragged into your documents, helping you to create page elements such as
calendars, newsletter sidebars and borders. Publisher integrates mail
merge features, which is handy when you need to send publications to a
list of customers, and it is possible to export publications as HTML Web
pages or PDF documents.
Microsoft Publisher is a desktop publishing software application capable of producing greeting cards, certificates, newsletters and other printed publications. The software comes complete with a wide range of pre-installed document templates, with more available free of charge for download from Microsoft's online service.
