Diffraction presentation and problem sheet for A level or IB. Using the diffraction formula (theta = lambda/b).

Written for year 9, traces the development of models for the solar system using observations of astronomical phenomena. Fairly comprehensive so could also be used higher up the school.

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.

Presentation and worksheet written for GCSE/IGCSE and simple IB.

Complete with music - written for GCSE/IGCSE Physics

GCSE PowerPoint explaining static electricity.

Presentation and worksheet (with answers) for refraction. Written for IB/A level this could also be used for some GCSE/IGCSE syllabuses.

PowerPoint and problem sheet for A level or IB.

Presentation, worksheets and practical activities for capacitors A level or IB. Is it in some GCSE courses too?! Includes explanatory video from the author too!

Force on a wire in a magnetic field and force on a moving charge calculation questions for A level or IB.

Brightness and luminosity worksheet for A level, IB.

Parallax angle questions for A level, IB.

Presentation and worksheet. Suitable for GCSE/IGCSE and A level.

Presentation and 2 worksheets for moments in KS3 or GCSE.

Presentation and all the worksheets and practicals you need to teach density. KS3 or GCSE. This presumes you have some material blocks and access to basic equipment (measuring cylinders etc).

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 you need to teach momentum and impulse to IGCSE, GCSE, A level and IB. Presentation with suggestions for practicals, worked examples, a cool video and worksheets. Great value for money!!

Everything you need for IGCSE/GCSE radioactivity. In the half life activity (Nihalinitis) you need to change the city to your own city and pick a student in your class for the symptoms! (I have a boy in my class whose name is like Nihalin) who has the symptoms displayed. It's meant to be light-hearted - he didn't mind! (For example you might have a boy named Gary in your class who is football obsessed and who like Justin Bieber - in which case the disease would be called "Garyitis" and the symptoms would include an obsession for football and Justin Bieber). You'll get the idea when you see the activity which uses spreadsheets to model radioactive decay.

Converging lenses, principal focus etc and drawing ray diagrams to find the position of images. Also includes a practical activity before the ray diagrams so students can see what the results actually mean. I have a running joke in my class about not liking dogs hence the questions on the worksheet. Please fell free to edit!!

Introduction to waves at GCSE/A level. This starts with an activity where they write a poem (!) to pre-assess words they already know. The PowerPoint then introduces the different measurements of a wave (frequency, amplitude etc) before introducing the wave equation (speed = frequency x wavelength) and a worksheet that uses the equation. It is handy to demonstrate the different types of waves (sound, light, slinky and even a Mexican wave in the class!)
