An engaging resource for students to practice their understanding of the two pressure formulas: P=height x density x gravity and P= force/area. Students have to calculate the pressure that each animal/person is subjected to at different depths in sea water. They are given the lethal force required for each organism, using the P=f/a formula they have to work out if they survive or not. Extension activities could include - finding out the maximum depth they have to be at before they would die etc... You could ask the students to find a liquid that has a much lower density in which the organisms could survive greater depths. My students loved it and I hope your students do too. Enjoy!

This powerpoint focuses on fixed resistors and calculating resistance using the band colours as well as the the resistance formulas used in circuits. This was made for a top set year 11 iGCSE class and features on the older Cambridge iGCSE syllabus. It is still relevant for all students studying resistance (fixed and variable) in electrical circuits and systems.

I found very few resources for this odd topic in iGCSE physics so i created this powerpoint for my classes. It explains the differences between the three logic gates and also when two or more are combined. There is an intro to boolean language and binary but not too much. It was used for a top set Year 11 iGCSE class but can possibly be used for lower age groups.

This is a PPT lesson with printable slides for students to use as worksheets (in groups is best). This was designed for the iGCSE Cambridge syllabus but it is relevant to all exam boards that contain static electricity topics. Build up of charges Electrons and Protons Discharge Sparks etc... Real life applications and suggestion for practicals. Balloons with polyester jumpers = attracts fine hair Balloon rubbed with jumper or silk cloth will attract small pieces of tissues paper The balloon will also 'magically' attract/repel an aluminium drinks can on it's side Use the charged balloon to bend a thin light stream of water from a tap. There is a video of lightning occurring outside my house which you can take out if you wish.

Cambridge iGCSE Physics: ATOMIC PHYSICS Extension Exam Questions +MS. I have isolated some extension level questions from some extended papers (paper 3) for CIE iGCSE physics. This resource includes 6 whole questions (41 marks total) relating to radiation, radioactivity, alpha, beta, gamma and cathode ray tubes. The mark scheme is attached within the PDF. The content belongs to CIE not me.

Cambridge iGCSE Physics: SOUND AND WAVES Extension Exam Questions +MS. I have isolated some extension level questions from some extended papers (paper 3) for CIE iGCSE physics. This resource includes 3 whole questions (22 marks total) relating to sound waves and general properties of mechanical & EM waves. The mark scheme is attached within the PDF. The content belongs to CIE not me.

Cambridge iGCSE Physics: LIGHT AND WAVES Extension Exam Questions +MS. I have isolated some extension level questions from some extended papers (paper 3) for CIE iGCSE physics. This resource includes 3 whole questions (21 marks total) relating to light rays, lenses and properties of mechanical waves etc. The mark scheme is attached within the PDF. The content belongs to CIE not me.

Cambridge iGCSE Physics: ELECTRICITY Extension Exam Questions +MS. I have isolated some extension level questions from some extended papers (paper 3) for CIE iGCSE physics. This resource includes 6 whole questions (46 marks in total) relating to electricity, electrical components and circuits etc. The mark scheme is attached within the PDF. The content belongs to CIE not me.

A 12 minute tutorial video about how a CRT and CRO works for the CIE Cambridge iGCSE physics syllabus. Features exam question at the end. Lots of visual stimuli and basic explanations for a varied audience. The video includes references to abstract humour (such as the Pitbull effect - like electrons he took his life from negative to positive). This video can be shown to your students and then they can summarise the content. You can pause the video and print the exam questions to hand out to students. As the teacher you can pause the video, rewind or fast forward areas that students may not understand fully. I hope you enjoy it!

13 Prepared Lessons for the complete teaching of the year 7/8 topic - Magnetism & Electricity (7.5). Completely inline with and supportive of the 2014 national curriculum changes. Each lesson is fully resourced with activities, worksheets, homework, starter, plenary and extension activities. This is a 'unit in a bag'. Each individual lesson is complemented by a structured and detailed lesson plan.
