INNOVATIVE TEACHING LESSON PLANGeneral informationName of the teacher: Lida G IssacSubject : ChemistryTopic : Ozone depletionStage : 14+ Curricular statementPupil develops factual knowledge, conceptual knowledge and metacognitive knowledge on the concept of ozone depletion.Content analysisTerms : Ozone depletionFact: CFC causes the depletion of ozone layerConcept:Ozone is a triatomic molecule of oxygen and is a protective layer of earth. It prevents harmful radiations coming from sun to our earth. CFC causes depletion of ozone layer. Learning outcomesEnables pupil to develop1. Factual knowledge on the depletion of ozone layer by, a) Recalling the concept of the formation of ozone. b) Recognizes that ozone hole due to the CFC.2. Conceptual knowledge on the depletion of ozone layer by, a) Arranging a drama. b) Showing a video,and a paper cutting.3. Procedural knowledge on the conservation of ozone layer by a) Doing and observing activities based on it. b) Raising question.4. Metacognitive knowledge on depletion of ozone by, a) Focusing on the idea that why we are celebrating world ozone day.5. Develops a positive attitude towards science.Pre- RequisitesThe pupil should have previous knowledge about pollutions

Class room interaction procedure

Pupils response

Teacher enters the classroom and greets the students. And they greet her back. In order to introduce the students into a new topic teacher shows a newspaper cutting and ask them why October 16 iscelebrated as world ozone day. (Students didnt respond as they topic is new to them).

Teacher then asks the students that now we are going to have a detailed study on that. Then she arranges the setup of a drama. She made them to stand in a circle She places a student at the centre and keeps a placard in his hand saying sun. The students standing around him keep the placard in their hands saying ozone (students). Some students having placards saying CFC comes and pushes away the ozone. Sun (student) throws some crape papers to the audience denoting the heavy rays of the sun. The ones who face the radiation are having severe diseases.

DISCUSSION POINTSTeacher enters into the stage and asks the students some questions

1. What is the main source of energy?

2. What is the name of the protection layer of the earth?

3. Do you know how this protection layer is formed?

CONSOLIDATION

Ozone is formed by the fusion of 3 oxygen atoms. Now you have seen there are some elements that destroyed the ozone layer and made trouble. Do you know what it is? And how it is made? (Students didnt respond) CFC is a compound that is the combination of carbon florin and chlorine. This compound is mainly found in perfumes, fridges and air conditioners .this causes formation of holes in the ozone layer and is called ozone depletion.

DISCUSSION POINTS

1. What will happen if there is holes in the ozone layer?

2. So isnt it our duty to protect this layer and what can we do to protect this layer?

Teacher shows the students a video related to the topic. https://youtu.be/WKrPd-8CJBM

Hope all of you have understood about the ozone layer and its functioning.

ConclusionOzone is a triatomic molecule of oxygen and is a protective layer of earth. It prevents harmful radiations coming from sun to our earth. CFC causes depletion of ozone layer.

Sun

Ozone

Dont know

The rays from the sun kill the earth

we have to the usage of products causes the emission of CFC

Question time Which is the protective layer of earth? What is ozone depletion? What are the components present in CFC?Follow up activityPrepare posters showing your concern about ozone depletion.
