the chemistry of water

The polarity of water

Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Oxygen also has two unshared pairs of electrons. Thus there are 4 pairs of electrons surrounding the oxygen atom, two pairs involved in covalent bonds with hydrogen, and two unshared pairs on the opposite side of the oxygen atom. Oxygen is an "electronegative" or electron "loving" atom compared with hydrogen.Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge () near the oxygen  atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms. An electrostatic attraction between the partial positive charge near the hydrogen atoms and the partial negative charge near the oxygen results in the formation of a hydrogen bond as shown in the illustration.

FILA Chart.

What is FILA chart?

FILA chart is actually the useful draft to solve the problems at a certain situation. For your information, F is stands for Facts, I for Ideas, L for Learning outcomes while A is stand for Actions. By using the FILA chart,we can list the facts from the problems,ideas,learning outcomes and some actions in order to solve the problems. It is very useful and make us more easier to identify and solve the problems.

 

 Problem Scenario 1:

Rosa, a new teacher was chose to attend a workshop on Learning & Teaching organise by the district education department. In the workshop she was exposed to many things such as learning theories, teaching methods, classroom management and assessment process. At the end of the workshop each participant needs to deliver a talk according to particular topic given randomly to them. The topic given to Rosa was Smart School.

As a curriculum officer how would you help Rosa?

Facts	Ideas	Learning Outcomes (Issues)	Actions
- A new teacher. - Was chosen to attend a workshop on Learning and Teaching organize by district education department. - Was exposed to many things such as learning methods, classroom management and assessment process - needs to deliver a talk at the end of the workshop. - The topic given is about Smart School.	- lacks of experiences and general knowledge. - needs to share the information with the other participants. - might be teaching in Smart School. -find information about Smart School and do preparation before the talk. - has to improved her communication skills. - enhance her self-confidence.	- What is Smart School? - What are the objectives of Smart School? - What are the concepts of Teaching and Learning in Smart School? - What are the differences between Smart School and ordinary school? - What are the roles played by the teachers, school and parents in order to achieve the objectives and goals of Smart School? - what are the challenges and benefits	- Surfing the internet to find information about Smart School. - doing researches for articles of Smart School at the library. - do the discussion with all the group members. - finish the assignment before the dateline.
