All they need to know for GCSE presented in a clear step by step and humorous fashion.

Revision podcasts for the first four topics in Cambridge IGCSE Physics (P1 Motion, P2 Matter and forces, P3 Energy, work and power, P4 Simple kinetic molecular model of matter). Ideal for this time of year, students can listen on their phones/ipods. BONUS formulae podcast. Students love this novel way to revise.

Some lateral thinking problems and their solutions. To be done in groups.

GCSE PowerPoint explaining static electricity.

Set of 4 straightforward worksheets with notes and questions testing their understanding of conduction, convection and radiation. Best done after the "standard" demonstrations. The "Convection stops!" worksheet is a "What if....?" scenario where students have to think about what would happen if convection didn't happen and fill in a mock newspaper front page. This could be adapted for conduction and radiation too.

Written for IB but could also be used for A level. Step by step explanation of orbital motion using a dog shot from a cannon (I don't like dogs! It's a running joke in my lessons). Includes calculations of centripetal acceleration etc - using angular velocity too.

Fully comprehensive presentation with a choice of tasks. GCSE/IGCSE/A level.

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!!

Fabulous "Moon crash" activity. Lesson and worksheets - everything you need. All ages. As featured in the TES moon landing commemoration edition.

Series of PowerPoints on the extraction of metals for GCSE/IGCSE Chemistry.

Half-life for IGCSE based upon the authors recent artcile in "My Best lesson" in the TES. Full instructions and presentation for a top of the range radioactive half-life lesson. Feel free to adapt the Disease (MrPorteritis) that is running rampant in Warsaw (or your own town) to model radioactive decay using spreadsheets.

Everything they need for A level or IB. Presentation, worksheet and answers. Written by experienced (26 years) Physics teacher. Humour too!

Written originally for IB, this can be used for A level too. Students are taken step by step through the Raleigh criteria and example problems. There is a practical activity and worksheet. Written (with humour) by a very experienced (26 years!) Physics teacher.

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).

Presentation and worksheets covering all they need for GCSE/IGCSE Chemistry electrolysis - including Faradays.

Print out both sheets - cut into dominoes and off you go! Completed dominoes should form a square/circle. Will take a group of 3 students about 20 - 25 minutes to do this excellent revision exercise. Also included is a sheet of Chemistry definitions to help their revision. Perfect activity for this time of year!

Presentation introduces how to measure speed (distance/time) and students measure some "fun" speeds (the speed of someone walking to a boring class, speed of someone walking to a fun class, speed of a drip going down the window etc). They are then introduced to speed calculations and there is a worksheet (that should be personalised with your class names - they love that!). Presentation is in a humorous style with fun pictures.

Students investigate the effect of adding resistances together in parallel using pencil lines on the worksheet. Will need standard multimeters to do this task. Includes PowerPoint, activity sheet and question sheet. Ideal for GCSE or A level/IB. Written by experienced Physics teacher (26 years!!).

The "True of false" opening activity is a great way to assess their understanding before the lesson starts. Emphasise throughout the lesson that gravity is a force between ALL objects (many students have been taught lower down the school that gravity is only what pulls them to the earth). The work sheet should give a good assessment of the understanding of the lesson. The last two questions will really stretch their (and maybe their teacher's!) understanding.

Everything they need to know about seeds, germination and cotyledons for Cambridge IGCSE Biology. Making a "mini-book" exercise at the end.
