Simon has been teaching Physics for over 27 years in British state schools and international school around the world. He specializes in International Baccalaureate, A level and IGCSE. He is now head of the secondary school at the British School of Tashkent, a Nord Anglia school and in August he will become International Principal of NAS Guangzhou Panyu. He is a regular contributor to the Times Educational Supplement and is one of their "Subject geniuses" for Science.

Suitable for all levels, KS2, KS3 or KS4 (let's presume by KS5 they've got it!). Ask the class to name each symbol before revealing the answer. Some funny "symbols" too! Finish by constructing some simple circuits around the class and getting the class to draw them as diagrams in a "circus" style activity.
Good starter or finish to a revision lesson. Students can either do thumbs up/down, hold up cards or move to different sides of the room. Good assessment exercise too.
PleasThese are PowerPoints and sheets I use in lessons and will need some adaption to your classes. Most lessons start with a "Do now" that students do as they enter. I should mention that there are running jokes about my dislike of dogs (sorry!
This could be used at KS3, 4 or even 5 level. A fun practical using multimeters and pencil lines to measure the relationship between resistance and length.
Lesson PowerPoint, worksheet and practical sheet. Written for IGCSE but suitable for GCSE and even A level. In the practical they can compare their results with the actual results and discuss why their results for the SHC is larger than the accepted value.
Presentation plus latent heat question sheet. The practical referred to in the presentation is the cooling of molten wax in hot water. I like to put the wax in a boiling tube in the beaker of hot water and take the temperature of the wax and the water as they cool to emphasise that the wax stops cooling when it reaches its melting point. This then leads into a discussion of latent heat followed by example calculations etc.
Digestion PowerPoint featuring all stages of digestion with humour too! "Draw the sentence" exercise to finish. Students have to "Draw" 8 sentences about digestion - ideally no more than one word per drawing. get them to divide a page into 8 boxes to do this. This is an excellent assessment technique to demonstrate their understanding of the Powerpoint. Suitable for KS3 and lower groups in KS4.
Presentation recaps heat transfer by conduction, convection and radiation in humorous style. This is then applied to how a vacuum flask works and students then complete the cut-out and stick worksheet. Good for KS3 and KS4.
You can’t beat an easy lung dissection to get students interested and possibly a little nauseous! Hopefully at the time of writing there are still some actual butchers shops surviving out there and you have no problem getting your hands on some sheep or pigs lungs, especially if you have an obliging laboratory technician to help. Try to get some with oesophagus and trachea attached.
I usually set the lab up beforehand to look as much like an operating room as possible. A table at the centre covered in white sheets, stage lighting if available, and if you can get hold of some scrubs even better (although a lab coat and a stethoscope will do). Teaching is partly a theatrical performance after all! I normally have stools arranged around a central bench – “in the round” so to speak.
Start by bringing attention to the smooth surface of the lungs and discuss how this helps, along with the pleural fluid, the lungs to move in relation to the rib cage. Remind the class of the role of the diaphragm contracting beneath the lungs and the intercostal muscles expanding the rib cage. Show where approximately the diaphragm is in relation to your rib-cage – it’s much higher than most people imagine. Being a good physicist I will explain how the air is PUSHED into the lungs by the surrounding air pressure - “In Physics, there is no such thing as suck!”
Contrast the flexible cilia-lined trachea made of cartilage with the muscular lined oesophagus. You can remind them of peristalsis by squeezing a Smarty down the esophagus with your fingers (it’s when it appears at the other end you might see a few green faces). Discuss the role of cilia in keeping dirt particles out of the lungs and how smoking can affect their action.
Before cutting the lung itself, inflate it using a blower (cue a couple more green faces). Then cut down the trachea with scissors, branching off into the bronchi, remembering also to discuss the role of surface area in the functioning of the alveoli. Cut a piece of lung and put it on water to show how light it is compared with a piece of meat, which sinks. You can ask “What would happen if the sheep/lung had drowned?” I normally finish by cutting a cross-section across a whole lung horizontally to show the lung riddled with cartilage bronchioles, explaining that’s why we don’t normally eat lungs!
I will usually then get the students to do a “Draw the sentence” exercise (my favourite) where they convert 8 simple sentences about the action of the lungs into drawings.
Three worksheets for the price of one. calculating resistance, adding resistances, and calculating power. Suitable for KS3 or IGCSE/GCSE (or even as a simple reminder for A level). Sheets includes notes and formulae as well as progressively difficult questions with some differentiation.
All lesson PowerPoints and activities for year 9 (and indeed GCSE) electricity.
Student confusion over words like “charge”, “current” and even “electricity” (whatever that is) is common. Why not simply talk about the movement of electrons – even lower down the school in year 7? It is much easier for students to visualize a flow of particles carrying energy than it is to comprehend vague expressions like “flow of charge” or to understand current as a flow of water etc.
Make lots of small pieces of paper (about 1 cm x 5 cm). Arrange the students around the room in a large circle with you at one side (with the paper) and a lit Bunsen on the other (with plenty of mats surrounding it!). The students walk slowly round the room, collecting a piece of paper from you, setting light to the paper at the Bunsen (and placing on the mats) and returning to get more. Ask them in groups to try to identify the elements in the circuit (perhaps by sketching). You are the cell (use correct terminology here), they are electrons, the Bunsen is a lamp and the paper is energy.
Everything they need to know for GCSE/IGCSE magnetism. Includes a "draw the sentence exercise. The slides can also be put on a loop and students can mind-map the information.
