Lesson
Presentation
The lesson presentation will introduce the students
to the concepts of pH, the pH scale and how to quantify the concentration
of hydrogen ions in a solution or substance. It is expected
that the students will have some exposure to scientific notation
before embarking on this lesson. If they need further explanation,
there is a link on the first page of the presentation to an explanation
of scientific notation. You may also access that link by clicking
here.
The concepts presented in this lesson may be difficult for the students
to grasp, that is why many link have been included in the presentation
that further explain concepts and have visual aids as well.
In addition, the following links may be helpful for the teachers
