Learning Outcomes
1.Factual     knowledge 2.Conceptual knowledge 3.Procedural knowledge    4.Metacognitive knowledge 5.Process skills 6.Positive attitude Entry behaviour:   Reference: Teaching-learning aids: 1.Chart: 2.Materials:	Enable pupil to develop factual knowledge of period number by, a)    Recalling the periods in the periodic table. b)   Recognizing the period number. Enable pupil to develop conceptual knowledge of period number by, a)    Explaining about the number of periods. b)   Demonstrating this with activities. Enable pupil to develop procedural knowledge of period number by, a)    Doing and observing activities based on it. b)   Raising questions about periods. Enable pupil to develop metacognitive knowledge of period number by, a)    Focusing on the idea that the period number is equal to the shell number. Enable pupil to develop different process skills like observation, hypothesizing, inferring and communicating. Develops a positive attitude towards science. Pupil should know about the periods in the periodic table. 1.IXth Standard Basic Science, Part-I 2.Handbook 1.About period number 2.Activity cards 1.Picture of window 2.Modern periodic table
CLASSROOM INTERACTION PROCEDURE	EXPECTED PUPIL RESPONSE
INTRODUCTION                 The teacher enters into the class and wishes the students. After the friendly talk teacher shows a picture of window. Then she asks questions related to the window. ·       What do you seen in the picture? ·       How the rod is arranged in the window? ·       Is the periodic table has horizontal rows? ·       Which is the name of the horizontal rows? PRESENTATION     After discussing these questions she enters into the topic periods. For this she shows the modern periodic table. MODERN PERIODIC TABLE After showing this, she discussed the questions related to the modern periodic table. DISCUSSION POINTS Ø Who is the father of modern periodic table? Ø Which is the name of the horizontal rows? Ø How many periods are there in the periodic table? CONSOLIDATION           The horizontal rows in the periodic table are called periods. There are 7 periods in the periodic table. Then to teach about the period number she divided the students into groups and gave an activity. ACTIVITY-1 Element Z Electronic Configura tion No. of shell Period No. Helium Boron Magnesium Calcium 2 5 12 20 ---- ---- ---- ----- ---- ---- ---- ----- ---- ---- ---- ----- Then ask questions related to the above activity. DISCUSSION POINTS Ø Which elements are there in this activity? Ø Are all elements having the same shell number? Ø What is the relation between period number and number of shells? CONSOLIDATION             The period number is equal to number of shells Then the teacher gave another activity to the students. ACTIVITY-2 Element Electronic configuration No. of shells Period number    A    B    C    D 2,2 2,8,2 2,8,5 2,8 ------- ------- ------- ------ ------ ------ ------ ------- Then ask questions related to the above activity. DISCUSSION POINTS Ø Can you write the period number when the electronic configuration? Ø How can you find the number of shells? Ø Is the period number and the number of shells are equal? Ø How can you find the period number? CONSOLIDATION            The period number is finding when the atomic number or electronic configuration is given.		The students gave reply to the teacher.

Yes By giving the atomic number or electronic configuration(BB)

                             

  CLOSURE

       What is the electronic configuration, period number of the element X, if its atomic number is 6?

                                  Element=X

                       Atomic Number=6

          Electronic Configuration=2, 4

                           Period number=2
