PHY_10_26_V2_TG_Mechanical and magnetic energy

Teacher Guides of the Lesson

Theoretical material for the lesson, definitions for concepts 

Instructions for demonstrations and safety

Warning: experiments should be performed under the supervision of teachers or students follow the instructions of safety procedures.

Additional guidelines for organizing a lesson 

1.      Organization moment. Establishing emotional state. Checking for absent students.

2.      Teacher introduces the topic and objectives of the lesson, assess criteria.

3.      Teacher organizes a class discussion on various types of energy. Then gives the definition of mechanical and magnetic energies.

4.      Teacher asks learners make comparison individually between mechanical and magnetic energy in terms of sources, formulae, properties and so on. Each student produces a poster (A3) which shows these very clearly. Any student in a class is invited to explain it to the rest of the class and then the class can assess for the poster which makes comparison.

5.      Teacher assesses each student’s posters by using assessment criteria and provides fair and helpful feedback.

6.      Stars and Stairs feedback

Recommendations for formative assessment

Activity1. Students discuss learning objectives and assess criteria.

          Activity2. Class discussion.

          Activity3. Teacher asks learners make comparison individually between mechanical and

                            magnetic energy in terms of sources, formulae, properties and so on. Each student  

                            produces a poster (A3) which shows these very clearly. Any student in a class is

                             invited to explain it to the rest of the class and then the class can assess for the

                             poster which makes comparison.

                             Teacher used group member’s responses to promote further learning…“What could

                              you add to that?” “Do you agree with that thinking?”

           Activity4. Teacher assesses each student’s posters by using assessment criteria and provides fair

                           and helpful feedback.

         Activity5. Stars and Stairs feedback
