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!

Characteristics of Living Organisms made for the Cambridge iGCSE Combined Science CIE 0653 curriculum Includes a PowerPoint with definitions of 7 characteristics of living organisms A slide at the end of the presentation that lists extra online resources A homework page ( 5 questions - one former past paper question) with answers A worksheet in case extension is required.

This lesson continues with bonding- focusing on Covalent Bonding. This lesson covers the spec: Definition of Covalent Bonding. State that non-metallic elements form non-ionic compounds using a different type of bonding called covalent bonding involving shared pairs of electrons. Draw dot-and-cross diagrams to represent the sharing of electron pairs to form single covalent bonds in simple molecules, exemplified by H2, Cl2, H2O, CH4 and HCl. Draw dot-and-cross diagrams to represent the multiple bonding in N2, C2H4 and CO2 * Again as with the previous lesson I find this a curious place in the course to deal with bonding - before having gone through the periodic table of elements. The previous lessons 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 classifying materials and the periodic table to make it relevant. 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 H2, Cl2, H2O, CH4 and HCl. Then when it comes to learning about the Periodic Table it will fall into place!

Cambridge Combined Science Syllabus (B2.1) This resource contains a PowerPoint lesson on the following topics: State that living organisms are made of cells Describe and compare the structure of a plant cell with an animal cell, as seen under a light microscope ( limited to cell wall, nucleus, cytoplasm, chloroplasts, vacuoles and location of the cell membrane) State the functions of the structures seen under the light microscope in the plant cell and in the animal cell Calculate magnification and size of biological specimens using millimetres as units. There are also multiple links here to online tutorials on how to use microscope and a practical investigation using a light microscope to view an onion cell. The supplemental syllabus includes some slides on relating the structure of cells to their functions There is a homework page with 10 questions and answers for teacher There is an additional small worksheet with table to be filled out

Homework sheets for Experimental Techniques and for Laboratory Equipment. Chemistry Complete with answer sheet. The question sheet is taken from teh lesson available also on TES which is 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 bundle covers an introduction to atomic theory. In includes a Power Point lesson that includes the topics outline below. It 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 This lesson cover the section C3 of the iGCSE unit 0653 combined science (some sections regarding the periodic table will be included in a separate section). 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.

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

The slides give an overview of the recent changes as well as a link to the official CIE website with the original specification. Embedded in the file are 3-word documents that explain the Chemistry, Biology and Physics syllabus in more detail. This is the perfect overview for anyone new to teaching the Chemistry, Biology and Physics Cambridge Combined Science Course or for anyone who wants to show students an overview of the course at the beginning of the year. As well as the PowerPoint presentation you will also find the three separate Word Documents with the Chemistry, Biology and Physics syllabus. I think this is useful for those who want to print it out and tick off what they have covered/as a table of contents etc, or as a handout to students showing what they need to cover for the exam. As always, I am happy to convert to other formats for those who are not MS fans. Thanks all and happy teaching.
