WHAT IS THE IMPORTANCE OF CHEMISTRY IN EVERYDAY LIFE??

Have you ever wondered about the importance of chemistry in everyday life? This is a question you may ask yourself if you're taking chemistry. Otherwise, finding an answer is one of the most common chemistry homework assignments. Here's a look at why chemistry is important.

Chemistry is important in everyday life because...

• Everything is made of chemicals. You are made of chemicals. So is your cat. So is your desk. So is the sun. Drugs are chemicals. Food is made from chemicals.
• Many of the changes you observe in the world around you are caused by chemical reactions. Examples include changing colors of leaves, cooking food and getting clean.
• Knowing some chemistry can help you make day to day decisions that affect your life. Can I mix these household chemicals? What are safe mosquito repellents? Will my bottled water expire?

PERANCANGAN PEMBANGUNAN PROFESIONAL

PROFESSIONAL DEVELOPMENT PLAN atau dikenali sebagai PERANCANGAN PEMBANGUNAN PROFESIONAL. 

 

Pencapaian:

    Setelah mendapat keputusan SPM pada tahun 2009, saya ditawarkan untuk meneruskan pelajaran ke Kolej Matrikulasi Johor dalam jurusan sains hayat. Bermula dari sana, saya merasakan saya lebih sesuai dengan karier sebagai guru dengan dorongan daripada mentor saya ketika berada di sana. Kemudian, tanpa berfikir panjang, saya memilih UPSI sebagai pilihan pertama saya berdasarkan kepada keputusan sijil matrikulasi dan saya memilih untuk menyambung pelajaran dalam bidang Kimia. alhamdulillah, berkat doa umi abah, saya, dan orang yang menyayangi saya, saya berjaya mendapat tawaran dalam Ijazah Sarjana Muda Pendidikan Kimia dengan Kepujian di Universiti Pendidikan Sultan Idris.

   Setelah berada selama tiga semester di sini, saya mula terbiasa dan gembira dengan kehidupan saya sebagai mahasiswi UPSI. Saya berharap agar saya berjaya membuktikan kepada kedua umi abah saya yang xberhenti menyokong saya daripada dulu sehingga sekarang yang saya akan berjaya membawa segulung transkripsi yang akan membanggakan mereka. Tidak hanya mengimpikan untuk berhenti belajar setelah memiliki ijazah sarjana muda, saya berazam untuk sentiasa belajar dan terus belajar sehingga ke peringkat yang termampu. InsyaAllah.

Bakal Guru Masa Hadapan

   Selepas bergraduasi, saya akan ditempatkan ke sekolah menengah kebangsaan yang akan ditetapkan oleh pihak Kementerian Pelajaran Malaysia. Saya akan mempraktikkan segala ilmu yang saya tuntut sepanjang berada di UPSI. InsyaAllah, saya akan menjadi guru contoh kepada pelajar-pelajar saya. Saya akan berusaha untuk menyahut seruan kerajaan dalam mencapai visi dan misi untuk membangun potensi individu melalui pendidikan berkualiti. 

   Tidak hanya ingin menjadi guru biasa, saya mengimpikan untuk menjadi guru yang hebat dan mencapai gelaran JUSA. Saya akan berusaha dengan bersungguh-sungguh untuk mendapatkan yang terbaik dalam hidup saya dan akan berbakti kepada masyarakat sebagai seorang pendidik selagi bernafas di dunia ini. 

CHEMISTRY MANIAC

Chemistry is a fascinating science, full of unusual trivia! 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/
• The only two non-silvery metals are gold and copper.
• 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.
• Dry ice is the solid form of carbon dioxide, CO2.
• Liquid air has a bluish tint, similar to water.

CORROSION OF METAL

Corrosion is the disintegration of an engineered material into its constituent atoms due to chemical reactions with its surroundings.
