lesson?
Previously, we’ve discussed about what is
electricity…
5. orientation
“Good morning ma’am”
(The students pay attention and listen to the
teacher )
Today we are going to discuss about basic
electricity…
B. Motivation
Random selection. Who can define what is
soldering iron and its function. I will give
additional 5 points.
C. Presentation
Now I am going to present to you what is
soldering iron through powerpoint presentation.
So, what is soldering iron…
