The complete ‘apparatus list’ as per 0653 Combined Science CIE syllabus. Complete with extra resources and a homework question sheet it’s a great starter to the ‘Experimental Techniques’ C2 section of the course.

One full lesson dedicated to separation techniques. Filtration, Sand and Water, Evaporation, Rock Salt, Distillation, Fractional Distillation etc. Designed for use with Cambridge 0653 Combined Science IGCSE course. This lesson comes with homework question page and answer sheet and additional quiz as part of powerpoint lesson. Recently updated

The next lesson in the iGCSE Cambridge Combined Science series Experimental Techniques this lesson includes slides on paper chromatography (describing technique and how to calculate RF factor) along with a homework sheet and list of online 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)

This lesson covers the following topics 1. Elements 2. Molecules 3.Compounds 4. Mixtures. 5. Physical and chemical properties and 6. Physical changes and Chemical changes CIE combined Science 0653 C3 Atoms Elements and Compounds. The lesson includes a Power Point presentation including all the topics outlined above plus a quiz on physical and chemical changes There is a lab lesson on compounds and mixtures (classic iron fillings and sulphur experiment) with word doc for students and teacher to follow. The lesson also contains a separate homework exercise (word document) Covers section first 2 specifications of C3 on the CIE 0653 GCSE Combined Science Course

Designed for the 0653 IGCSE Combined Science Course. This presentation is perfect for any introduction to Chemistry class. It contains an introduction to matter, the states of matter, atoms and molecules. It also includes a question page an experiment overview ( pour a gas) and a list of extra resources.

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

Today it is all about ions. What are ions, how are they formed what is ionic bonding and how we can describe the formation of ionic bonds: This lesson covers the spec: Describe the formation of ions by electron loss or gain Describe the formation of ionic bonds between elements from Groups I and VII. Describe the formation of ionic bonds between metallic and non-metallic elements to include the strong attraction between ions because of their opposite electrical charges* ( Higher Level) Describe the lattice structure of ionic compounds as a regular arrangement of alternating positive and negative ions, exemplified by the sodium chloride structure* ( Higher Level) I find this a curious place in the course to deal with ionic bonds - before having gone through the periodic table of elements. The previous lesson does deal with orbitals and electron configuration , but logically I would prefer to move onto the Periodic Table after this. Anyway I have tried to also explain a little about Group 1 and Group 7 elements- however this may be confusing for those who have limited knowledge of the periodic table of elements. The PowerPoint goes over the basics as per the Spec but also included is a work sheet/homework page with solutions for the students to work on. My advice is to practice these dot and cross diagrams as much as possible and at the end of this lesson students should be able to draw the bonds between NaCl, MgCl, KF LiCl MgF2 and CaO then when it comes to learning about the Periodic Table it will fall into place!
