Level : Secondary 1 NA / Express Topic : Separation of Mixtures

Learning outcomes (including use of basic skills and process skills): Students will be able to: 1. describe the different methods of separating mixtures. 2. identify and set up appropriate apparatus for separating different mixtures. 3. display proper separation techniques.

ICT tools: Internet (Seach engines, Wikispaces...etc), Digital Video recorders, Window Movie Maker, Microsoft Powerpoint.

DESCRIPTION OF ACTIVITY Pre-knowledge: Students would have covered properties of mixtures and the basic concept of various separation techniques.
 * || **Description of activity:**

Given various mixtures students are to state and demonstrate suitable separation techniques and procedures which will be flimed and put online for discussion. || **Essential features of inquiry: For each feature, mark on the continuum if you are planning for more self-directed (SD) or more Teacher guided (TG) inquiry** || Evidence LC --X-- TG Explanation LC --X-- TG Connection LC --X-- TG Communication LC -X--- TG ||
 * Question || There are different separation techniques for separating different mixtures. Students will be given different types of mixtures and they are to identify suitable separation techniques for each of the mixtures. || Question Learner-Centered --X-- Teacher-Guided
 * Evidence || Students will work in pairs and carry out 2 experiements: separation of mixture of sand and salt, paper chromatography. One student will be doing the experiment while being flimed by his/her partner and vice versa. Teacher will select some video clips and put on wikispaces for classroom online discussion on the proper use of separation techniques and procedure for subsequent lessons. ||  ||
 * Explanation/ Communication || Students are to view the videoclips on wikispaces and comment online in discussion forums.

Students will then be encouraged to go online to reseach on NEWater (reverse osmosis) and present their research using powerpoint in class. Students are also encouraged to relate and come up with examples on what they have learnt to their daily life. ||  ||

Evaluation of Pupils' Learning: !. Through their comments and reflections given online. 2. Presentation in class 3. Pre-test (to evaluate students' understanding), followed by a written Test.
