Teachers Guide Lesson Plans Chemistry, The Government of Punjab has a strong desire to improve the quality of teaching and learning. in the classroom Various initiatives have been undertaken for provision of quality education. to students in the Province Provision of quality education at secondary level is an important. step towards building an education system meant to contribute meaningfully towards. development of our society To achieve the desired goal activity oriented training for. secondary school teachers based on modern teaching methodologies has been considered. imperative and crucial, Directorate of Staff Development DSD has been training in service and pre service. public school teachers and developing educational material since its inception Considering. the quality work produced over the years the task of development of the Teachers Guides for. secondary school teachers in the subjects of English Physics Chemistry Biology and. Mathematics was assigned to the Directorate of Staff Development by the Provincial. Government, DSD worked in collaboration with over three hundred professionals i e Teachers Book. Writers and Teacher Trainers from both public and private educational institutions in the. subject of English Physics Chemistry Biology and Mathematics who worked in groups to. develop these comprehensive Teachers Guides These Teachers Guides with textbooks are. aimed to achieve Students Learning Outcomes SLOs through the teaching materials and. methodologies which suit varying teaching and learning contexts of Punjab These Teachers. Guides will help secondary school teachers to deliver and further plan their content lessons. seek basic information on given concepts and topics and assess students understanding of. the taught concepts, The DSD team acknowledges the cooperation extended by various public private. national and international organizations in the preparation of Teachers Guides DSD. recognizes the contribution made by all developers and reviewers belonging to following. organizations including German International Cooperation Agency GIZ Institute of.

Now tell students that similarly Ask the following questions from students to. elements are arranged in periodic table assess their learning. in order of increasing atomic number How elements are arranged in the periodic. Define the modern periodic law,Activity 3 Differentiate between group period. Concept of Group and Periods Differentiate between S P block elements. Teacher will explain the group and,periods with the help of seating Follow up. arrangement of students in the, classroom A B and C are three elements in the same. Students in 1 vertical row will be asked period of the periodic table A is a non metal. to stand up group B a metal and C is a transition metal What will. Students in the 1 horizontal row will be,be correct order of these elements in the.
asked to stand up period,periodic table moving across the period from. Teacher will then repeat activity with,left to right. Group2 and Period 2and students will, stand accordingly Find out why hydrogen is placed at the top of. Atomic model will be displayed in the group 1 of periodic table.
