9/4/2012 ~ Easter Monday

 

Date	10/4/2012
Time	8.15 am - 9.15 am
Class	4 Science 3
Subject	Chemistry
Theme	Matter Around Us
Learning Area	Periodic Table Of Elements
Learning Objective	Analysing elements in a Period
Learning Outcome	Student is able to : a) List all elements in Period 3. b) Write electron arrangements of all elements in Period 3. c) Describe changes in the properties of elements across Period 3. d) State changes in the properties of the oxides of elements across Period 3. e) Predict changes in the properties of elements across Period 2. f) Describe uses of semi-metals. g) Identify the positions of the transition elements in the Periodic Table h) Give examples of transition elements i) Describe properties of transition elements j) State uses of transition elements in industries
Activities	Discuss : a) Changes in the properties of elements across Period 3. b) Properties of transition elements with respect to melting points, density, variable oxidation numbers and ability to form coloured compounds.
Noble Values	Appreciating the contribution of science and technology.
Teaching Aids	a) Text book b) Reference book
Reflection	Before the lesson start, teacher recalls back their knowledge by discuss the term electronegativity and electropositivity regarding Group 1 elements and Group 17 elements. All of students understand well and only then teacher proceeds with elements in period 3. At first, about 10 of the students do not understand the trend of atomic radius because they get confuse with the trend of size in the Group 17 elements. Teacher reinforces again by comparing both trend and use analogy to make them understand better. Students have no problems with lesson of transition elements, their properties and uses. Students do exercises to evaluate their understanding.

 

Date	10/4/2012
Time	9.45 am - 10.55 am
Class	5 Science 1
Subject	Chemistry
Theme	Interaction  Between Chemicals
Learning Area	Oxidation And Reduction
Learning Objective	Analysing redox reaction
Learning Outcome	Student is able to : a) State what oxidation is b) State what reduction is c) Explain what redox reaction is d) State what oxidising agent is e) State what reducing agent is f) Explain with examples oxidizing and reducing agents in redox reactions
Activities	Collect and interpret data on oxidation, reduction, redox reaction, oxidising agent and reducing agent based on : a) loss or gain of oxygen b) loss or gain of hydrogen c) transfer of electron
Noble Values	Appreciating the balance of nature.
Teaching Aids	a) Text book b) Reference book c) Mahjong paper d) Marker pens
Reflection	All of students have no problem to identify the process of oxidation and reduction. They also able to define the meaning of redox reaction. Teacher also discovers that students have no problems to identify the oxidizing agent and reducing agent. They find it is easy when define redox reactions in terms of loss or gains of oxygen as well as loss or gains of hydrogen. But during activity time, teacher discovers that student do not really master in applying their previous knowledge on electron transfer in identifying the oxidation and reduction process. They get confuse and difficult to find which one is oxidation and reduction process. Teacher monitors and guides them. Only two groups are able to present today. Other presentations will proceed on the next lesson. Teacher has to give more exercises since most of the students do not really master the redox reaction in terms of electron transfer. Today's objectives only achieved about 90%.

Learning Outcome	Student is able to describe the process of mitosis
Activities	Discuss the process and importance of mitosis
Noble Values	Appreciating the balance of nature.
Teaching Aids	a) Textbook b) Reference book
Reflection	Today's objectives are achieved. All of students are able to draw the process of mitosis properly. Teacher checks their work one by one and satisfied with their work.
