Main sources of

electricity are dry cell,

dynamo, accumulator,

solar cell and

hydroelectric power. How dry cell, dynamo,

accumulator, solar call

and hydroelectric power

generate electricity.

Devices that use dry cell,


solar call and

hydroelectric power to

function.

1. Teacher uses PowerPoint andquestion to guide studentsunderstand the sources ofelectricity.

2. Teacher shows a picture of dry cellto students.

3. Students state the things in the

picture are dry cell.4. Teacher shows the different types of

dry cell to students.5. Student pastes the flash card of

Dry cell on the board.6. Teacher shows structure of dry cell

to students.7. Students answer the questions

asked by teacher.

T : How dry cell produces electricity?S: Reaction between chemical in the

dry cell.T : How is the flow of electricity?S : Electricity flows from positive

terminal to negative terminal.T: If the chemical in the dry cell is finish

can it be used again? Why?S: No. Because chemical reaction

cannot happen in the dry cell again.

T: Do you have heard rechargeablebattery? What is it mean?

S: Yes. It means we can use it againafter charge.

T: Which devices use dry cell tofunction?

S: Clock, torch light and remote controlT: What the advantage of dry cell?S: It is small, easy to carry and

affordable.
