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

A combined resource with 4 lessons containing: 1. Chem syllabus 2017-2018 2.Apparatus List (with worksheet) 3. Lesson on Matter (with extra resources, and homework sheet) 4. Lesson Experimental Techniques (with quiz and homework page) 5. Lesson on Paper Chromatography with homework page and extra resources

This lesson covers an introduction to atomic theory. In includes a Power Point lesson covered the topics outline below. It also includes a revision or homework page (with answer sheet). A ‘Hot Seat Quiz’ that includes the key terms covered in the lesson and a printable of the key figures in Atomic Theory. The Power Point lesson covers the key terms: • Atomic theory • Atoms • Atomic structure • Protons • Neutrons • Electrons • Atomic Mass Unit This is followed by a section covering describing atoms: • Electron configuration • Mass Number (Nucleon number) • Atomic number (proton number) The last section covers briefly • Isotopes • Relative Mass Unit • Relative Formula Mass Designed to partially cover section C3 of the iGCSE unit 0653 combined science CIE course as outlined on the Cambridge Specification here: 3.3 Atomic structure and the Periodic Table 1 Describe the structure of an atom in terms of electrons and a nucleus containing protons and neutrons. 2 Describe the build-up of electrons in ‘shells’ and understand the significance of the noble gas electronic structures and of valency electrons (reference to noble gases not included - this will be in periodic table lesson) 3 State the relative charges and approximate relative masses of protons, neutrons and electrons. 4 Define atomic (proton) number and mass (nucleon) number. 5 Use proton number and the simple structure of atoms to explain the basis of the Periodic Table ((Not yet included in this section)

Contains the first section of the IGCSE course, in 4 lessons. It starts with the syllabus then an apparatus list, followed by a lesson on Matter and Experimental Techniques. All lessons come with an additional homework assignment (Word Document). Email me if you have any questions or wish to see a better preview.

C3. Atoms, elements and compounds 3.3 Atomic structure and the Periodic Table 1 Describe the structure of an atom in terms of electrons and a nucleus containing protons and neutrons. 2 Describe the build-up of electrons in ‘shells’ and understand the significance of the noble gas electronic structures and of valency electrons (reference to noble gases not included - this will be in periodic table lesson) 3 State the relative charges and approximate relative masses of protons, neutrons and electrons. 4 Define atomic (proton) number and mass (nucleon) number. 5 Use proton number and the simple structure of atoms to explain the basis of the Periodic Table (see section C9), with special reference to the elements with proton numbers 1 to 20. (not yet included in this section) In addition, this lesson is combined with the Atomic Theory Timeline. This is not on the IGCSE syllabus however it is a great topic for class research, a mini homework assignment, it can make a nice addition to the course, an introduction to the idea of scientific models or just as an introduction to the periodic table or atomic theory. This separate PowerPoint contains a lot of detail; thus this Atomic Theory Timeline resource 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. It is a good introduction to 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.
