Brightness and luminosity worksheet for A level, IB.

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 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.

Year 9 or GCSE. PowerPoint discusses terminal velocity and falling without air resistance and there is an investigation (with investigation write-up template) at the end. I should mention that there are running jokes about my dislike of dogs (sorry!).

Presentation and 2 worksheets for moments in KS3 or GCSE.

Students investigate length of day in Summer/Winter. Each group of students need a light source and access to a globe (blow up ones will do). The instructions are quite hard to follow for some kids - perhaps groups could be organised by attainment and the teacher could assist the lower group.

Useful for KS3 or KS4. Includes a nice exercise using the final bobsleigh run from "Cool Runnings" which is available on YouTube.

Mr Porter's amazing "Revise by writing" sheet. Students have to use 47 words to describe various pictures - convection, terminal velocity, latent heat, etc. Once you've seen the idea and used the sheet you can apply this to just about any topic (in Chem and Bio too).

Complete with music - play as a class - don't forget their lifelines! About 20 - 25 mins of classroom fun if played like the real game.

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.

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 and worksheet on the difference between evaporation and boiling and the factors which affect the rate of evaporation.

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.

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

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