# Standard Level Core

#### Core or Base?

A core is the centre of something but I'm not sure that the syllabus core is really the centre, I would call it the base since it's the basics that everything else is built upon. The old syllabus was presented in a ready to go teaching order I don't think the new one is. Some of the "themed groupings" of topics don't make so much sense to me which is why I changed the order in my book, for example I would rather teach cells before the heating effect of electric current. Anyway here is the order of topics in the subject guide.

 Measurements and uncertainties Measurements in physics This is really just an introduction to physics and something about quantities, measurement and uncertainties. Most students will know all of this but I always like to start at the beginning especially with students who have never studied physics in English (most of mine). To give it some context, the uncertainties part is done as part of the practical programme. Uncertainties and errors Vectors and scalars Mechanics Motion After the introduction the logical next step is mechanics, how can students learn about charges particles and the kinetic model of a gas before they can model the motion of a simple rubber ball. Through basic mechanics we can logically introduce concepts such as momentum, force and energy that will be use throughout the course. Forces Work, energy and power Momentum and impulse Thermal physics Thermal concepts It might make more sense to take SHM and waves before thermal physics but which ever way round it should come after mechanics so that concepts such as heat end internal energy have some meaning. Modelling a gas Waves Oscillations SHM is an extension of mechanics using the already defined quantities of force and acceleration but in a more difficult context. The study of waves also requires students to understand motion (e.g. velocity) and also see how a wave has different behavior to a particle. Travelling waves Wave characteristics Wave behaviour Standing waves Electricity and magnetism Electric fields The microscopic model of conduction is the motion of particles again and solving circuit problems needs some understanding of energy. It makes sense to do electric fields before circuits. Good that electric potential is now back in the syllabus. Heating effect of electric currents Electric cells Magnetic effects of electric currents Circular motion and gravitation Circular motion I'd put this a bit earlier especially for HL where the circular model for SHM is worth using. Newton’s law of gravitation Atomic, nuclear and particle physics Discrete energy and radioactivity In this topic we draw on knowledge gained in mechanics (energy and forces), waves (EM spectra) , electrical fields (electron gun) there are very few new concepts in this topic just applying old ones to something very small. In particle physics we have to introduce some new tricks to explain what interactions are possible. Nuclear reactions The structure of matter Energy production Energy sources Again nothing new here just application of pretty much everything, a good revision topic to do at the end. Thermal energy transfer
