STEPS IN PREPARATION OF LESSON PLAN

Teaching points	Multimedia material used	Teaching Learning Process	Rationale for the use of Multimedia Media	Skill develop
Recall taste of few edible substances		First PT will ask a riddle to students, after getting response from the student. Yes Lemon is the correct answer.   Lemon is one of the edible substance we use in our daily life. Like lemon We use large number of edible substances. Pt will further enquiry :   “Do they have same taste”?   After getting response Pt will say so Lets recall about the taste of few substances and you have to guess Are they taste sour,bitter, salty.       After getting response from the students PT will further indulge students in enquiry and brainstorm do they know??   “Why all these substances taste sour”?   Students will become curious about the topic further.   After getting response from students. PT will announce the topic, Well students, Today we will try to learn   Why all these substances taste sour?	Inquiry approach     Riddle is used by Pt to link the topic with previous knowledge. Question ask  by Pt will help students to recall about various taste that they studied in their previous classes.     Inquiry Approach                                   Problematic Question.         Inquiry approach	imaginative skill                 Hypothetical skill                                               Scientific skill
Comprehend term acid		Pt will say,   Lemon, orange are citrus fruits because they contain citrus acid.   Tomato ketchup is made from tomato which taste sour due to the presence of oxalic acids.   Curd taste sour due to the presence of lactic or milk acid.   Now, students will you try to frame definition of acid. Then Pt will explain     Lemon, Orange, Tamarind , Curd all these taste sour due to different acids.    With the help of the students pupil teacher will frame the define of Acid.   “ The substances that are sour in taste are called acids.”   Now Pt will ask are you people know about some properties of acid?   Now PT will say all acids contain hydrogen. “is this statement true or false”?   Some say yes whereas some say no. After getting responses from students Pt will explain with the help of an example of water and sodium hydroxide.   And said acids contain replaceable hydrogen, means when it reacts with water releases Hydrogen ion.   Then Pt will say this our first property of acid that acid contains replaceable hydrogen.   Now Pt will demonstrate an activity by dissolving lemon juice in water and ask student try to form hypothesis.   Then after taking responses from the students Pt will explain this is our second property of acid that it is dissolve in water.   So lets find out  some more properties of acids with the help of an activity. Both Pt and students will discuss and start demonstrating an activity.   Pt will demonstrate an activity by dipping the ends of circuit in lemon juice and ask from students what do you infer from it?   Students will say lemon juice conducts electricity.   Pt will say yes students “this is another property of acids that it conducts electricity”.	Explain topic with the help of image in order to provide better version of learning.         Relate with example provide better clarity to the students.               Frame define with the help of students built hypothetical skills.             Lecture cum Demonstration method                                                         Demonstration helps in developing better concept and also built analytical skills.               Demonstrati on method               Scientific skills develop by live demonstration and also Generate curiosity	Exploring skill
Associate Different acids contain by different substances.		Pt will show a matching activity and ask students to help me out in matching different acids contain by different substances.   After getting responses Pt will say well students these some basic acids in which we deal everyday.	Activity is used by Pt to increase the curiosity among students.	Scientific skill
Discuss Two different type of Acids.		Pt will explain that there are two type of acids;   1.    Organic Acid 2.    Mineral Acid   Acids that are found in plants and animals are called organic acids. e.g.: citrus acid, Lactic acid, Formic Acid.   Acids prepared from the minerals of the earth are called mineral acids.   HCL, ,	To create interesting environment in the class.	Listening skill
Illustrate Several precautions		After explaining types of acids, Pt will show some images to student and ask them to carefully observe them. Now Pt will ask What do you infer from these two images. After getting responses Pt will start illustrate about the precautions while handling with acids.   Never handled with bare hands or tasted.   Always add acid in water not water in acid.   Always wear proper equipment while dealing with an acids.	Inquiry approach     Image help student for better understanding of process.     To enhance the observation skills of students Pt will show images.	Observational skills

Recapitulation                                    

For recapitulation Pt will select some points based acids and some are not then Pt will ask students to select appropriate points and insert them on this given circle.

 

Extension of Learning                      '

 Pt will ask students                                    

1. To make a list of at least 10edible substances which contain acid?

2. Are acids always evil. Justify your answer
