Hello, I hope you find my lessons covering the iGCSE CIE Cambridge 0653 Combined Sciences course helpful. I have noticed my lessons do not show much preview ( just first and last page) so please contact me if you wish to see more slides from any of the presentations.

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

Physical and Chemical Properties and Changes

(0)
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 The lesson includes a PowerPoint 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 sulfur experiment) with word doc for students and teacher to follow. The lesson also contains a separate homework exercise (word document) Covers section C3 of the Cambridge CIE 0653 GCSE Combined science course but can easily be used as a stand alone lesson on Physical and Chemical changes

Ions and Ionic Bonding IGCSE Chemistry Cambridge CIE

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!
