本研討會將由兩所中學的教師介紹他們在整體課程發展的校本經驗。主題包括「運用英語學習科學」和「發展科學過程能力」。  

中學校長、副校長及科學教育學習領域統籌主任、科主任和教師可參加本課程。 

有興趣參加的老師請透過教師培訓行事曆報名。

The best way to study solvent extraction is to carry out related experiments but the concept of dynamic equilibrium is a bit abstract. I hope that the following may be of help.  Try this.

Once, a student have asked me ‘In the animation, why there is a fluctuation of particle count and the partition coefficient is not quite constant ?’  My answer was “That is really  the dynamic nature of equilibrium.  However, even with a concentration as low as 0.001M, a few thousands difference in no. of particles would still give a fairly constant ratio of concentrations. Can students do a little calculation and find it out ? What would you say ?

Would it help your students to understand the concept of dynamic equilibrium and distribution law better. How and where it should be integrated in your teaching are up to you. 

Chemistry teachers are invited to join the captioned course. Details of the course are as follows: 

Date: 11 June 2012 (Mon) or 14 June 2012 (Thu)

Time: 9:30 – 12:30 & 14:00 – 17:00

Venue: Room 6124 (lift 19 / lift 22), 6/F, The Hong Kong University of Science and Technology, Clear Water Bay, Kowloon

As the course consists of a lecture and a practical session.  Seats are very limited.  Interested teachers please enrol the course through Teacher Calendar System as soon as possible.

The video is a demonstration on how rate of reaction is being affected by surface area, produced by Royal Society of Chemistry and is interesting.  Traditionally in laboratory marble is used, but in this demonstration some milk powder is used.  Click to view the video.

What students would discover by playing around with the simulation is unlimited. Give them time to explore and make sure that they keep record of their discoveries, compare and discuss their discoveries with others.  While using it in a classroom, I would rather not to allow students reading/copying from books unless it is really necessary.   One 40 minute lesson would be enough.

Those who would like to have just the simulation without suggest tasks, please let me know (chungshiukin@hotmail.com) so that I can upload another one tailor made for you.  Sometimes, the more we suggest and give them, the less likely they would explore or discover.  It depends on abilities and attitudes of the class.  Would class discussion leads to consider factors like catalyst, time, mole and volume instead of concentration, etc. I have retired and my present goal is to enhance teaching/learning chemistry using IT.  Hope this may be of help.
