Description

In this chapter, the students will find out: The ideas of work and power How to calculate work and power. This lesson starts with the evaluation of last experiment-3.10 Work on an inclined plane-which some of the students were not able to attend due to DI competition in Poland. This is fallowed by small group discussion about open end questions and presentations. Finally the students complate the end of topic questions on page 108. So they can check their own learning, and they can ask me for help.

Main Aims

  • To provide of language used for Transformation and conservation of energy in the context of Transformation of g.p.e into the k.e. and doing work

Subsidiary Aims

  • To provide clarification of language used for following instructions and team work in the context of n
  • To provide clarification of language used for following instructions and team work in the context of not only

Procedure

Warmer/Lead-in (15-20 minutes) • to get the students who are weak and missed the last lesson by the studends who are good at physics to a level for starting the evaluation of last experiment.

Experiment set-up will be prepared by the teacher. 5 balanced ability groups will be made by the teacher. The students will go over the experiment sheet on iPad by examining the set-up.

Test #1 (5-8 minutes) • To gauge students' prior knowledge of the relation between change in energy and work done?

Three further examples of forces doing work: Which of the forces is/are doing work? Argue your answer in term of change in energy. Pushing a shopping trolley to start it moving. An apple is falling from a tree. Breaking to stop a bicycle.

Teach (20-25 minutes) • to see the equality of change in energy and work done.

The experiment-sheet will be projected by the teacher. The students will try to answer the questions, and this stage will be moderated from the teacher by using QA-teaching method.

Test #2 (10-12 minutes) • Check students' use of the relation between change in energy and work done? and compare with the first test

Three further examples of forces doing work: Which of the forces is/are doing work? Argue your answer in term of change in energy. Pushing a shopping trolley to start it moving. An apple is falling from a tree. Breaking to stop a bicycle.

Free practice (13-15 minutes) • To provide students with free practice of the relation between change in energy and work done?

This time the students have to solve the questions from 8.3 to 8.7, on page 108 on their own.
