A PowerPoint presentation about how to balance chemical equations. Useful when printed as a handout or when used as an actual presentation.

A very clear powerpoint presentation showing the ‘arrows in boxes’ electronic sub shell filling order from hydrogen to krypton. My students find this very helpful and it is useful when printed as a handout. It also shows clearly the incomplete 4s subshell in chromium and copper.

A quick test on atomic structure

A multiple choice test on the elements of group 2 and group 7. Suitable for advanced level students.

This is a fun (and moderately challenging) crossword puzzle that would serve as an excellent starter, plenary or in-lesson activity for any radioactivity and isotopes class. This crossword tests students’ knowledge of: Isotopic/atomic structure The difference between alpha, beta and gamma radiation Knowledge of the isotopes of hydrogen (i.e. deuterium and tritium) Radioactive decay and half-life The use of Uranium-235 as an electricity generating fuel This is a lot of fun and my students loved it. If your kids have never learnt anything about the radioactivity and isotopes before, then you could provide the students with a summary to help them as they do the puzzle. In this pack you get a PPTX (which you can edit), a pdf version and a png of the puzzle itself (in case you want to project it on your interactive whiteboard for students to fill in).

These slide presentations cover all of the syllabus requirements for Edexcel IGCSE Physics Unit 1: Forces and Motion. Topics covered include: Unit conversions Movement and position Forces, movement shape and momentum The slides will be applicable to other exam boards too.
