Atomic Theory
Atomic Theory Timeline:
This extra lesson is not explicitly covered by the Cambridge iGCSE syllabus but it makes a nice addition to the course, as project work, an introduction to the idea of scientific models or just as an introduction to the periodic table or atomic theory.

Each PowerPoint contains a lot of detail, thus this lesson is not really intended to be delivered in the presentation format as like my other lessons.

The PowerPoint covers how a theory may change as new evidence is found. How a scientific explanation is conditional but may become more convincing when predictions based on the model or theory are confirmed later on by further ideas/scientific data.

The lesson covers the concept of models, a brief overview of atoms, a printable of the atomic theory timeline and slides on the models proposed by various key figures in the atomic theory timeline.
There is as always a list of extra resources and a question page (just one question) at the end of the PowerPoint
