Curricular statement

  The pupils are made aware of the topic “Allotropes of carbon” through observation discussion, interviewing the teacher etc.

Content analysis

New terms: allotropes, diamond, graphite etc

Facts:

•       Carbon is seen both in elemental state and combined state in nature
•        Diamond, graphite, fullerene and graphene are allotropes of carbon
•        Diamond is the hardest allotrope of carbon
•        Graphite is most stable crystalline allotrope of carbon

Concepts 

Major concept: Allotropes of carbon- Allotropy is the phenomenon by which the some element exists in different physical forms

Minor concept: diamond, graphite and fullerenes are allotropes of carbon

Learning objectives

•         Remembering the above mentioned terms, facts and concepts related to the topic allotropes of carbon
•         Understanding of the above mentioned terms, facts, and concepts related to the topic “allotropes of carbon”
•         Applying the ideas to develop the different structures of allotropes.
•        Analyzing the characteristics of diamond, graphite and fullerene.
•        Synthesize the different terms associated with allotropes of carbon.
•        Create, deep knowledge about the topic and allotropes of carbon

To develop the process skills through interviewing and communicating

Learning aids

                     Activity card containing certain questions related to the topic allotropes of carbon

Product of learning

Additional knowledge 

                   The refractive index of diamond is very high

Pre- requisites

                    Pupils have the knowledge of the element carbon

	Classroom interaction procedure
Teacher	Introduction:after establishing a good rapport with students the teacher checks the knowledge of pupil about carbon Today you are going to interview me ,can you guess who Iam? I am carbon
Students	Greet the teacher and listen to her carefully
Teacher                     :	Presentation Common, quickly form four groups.Distribute the questions to each group kindly go through questions carefully. After that select your representative to interview me.If you need any information kindly feel free to ask me and I will try to help you
Student	Hello, can you please introduce yourself?
Teacher	I am Carbone.In my family we are five members, silicone , Germanium, Tin, Lead, and me
Student	Mr. carbon, you play a very important role in our daily life. Can you tell me how you must exist on earth?
Teacher	I am  the basis of life, without allotropes I cannot exist if I disappear off the face of the earth right now, all life itself would cease to exist, without me life itself would not be possible.
Student	What is allotropy?
Teacher	Allotropy is the phenomenon by which the same element exist in different physical forms
Student	Would you please explain how you form allotropy?
Teacher	I am different from the other elements I am so unique that  I am  capable of binding to myself and other elements through the use of single, double and triple bonds. This results in chains and rings. When I bind myself in chains and rings I form allotropes
Student	When we think of carbon, what comes to our mind is a black, chalky substance coal. How do you transform yourself in to beautiful and transparent diamonds?
Teacher	Most people probably think of me as coal, but actually 100% of me is diamond and only 92% is coal. Diamond is the hardest naturally occurring substance. It is an excellent insulator of electricity. It is used in the preparation of ornaments and in industry.
Student	It is a known fact that graphite is a good conductor of electricity. Can you give me a few more characteristic properties of graphite?
Teacher	I am a smooth in the form of graphite. Graphite does not vaporize and has high melting point. I am used as lubricant to reduce friction in machines.
Student	Carbon, you are nicknamed bucky balls, Do you like that name?
Teacher	Yes of course, I am proud of it because another interesting allotrope of me called fullerene was designed by the American architect Buckminster Fuller. Fullerenes and its compoundsare of great use as catalysts, lubricants and super conductors of electricity
Student	Does any other allotrope exist ?
Teacher	Yes of course, Myanother allotrope is graphene. It is the basic unit of graphite and fullerene. It is two hundred times stronger than steel and also a good conductor of heat and electricity
Student	You are awesome. Congratulations. You performed very well
Teacher	Thank you for your whole hearted participation and co-operation

Consolidation

•        Allotropy is the phenomenon by which the same element exist in different physical forms
