Spectroscope

Using a hand spectroscope causes many problems for the students to observe what they are supposed to see. Using the camera I can at least ensure that even if the student could observe the spectra themselves they have looked at what they should have seen
 

Thermoelectric Generator

 Thermoelectric Generator or a Seebeck generator works via a heat transfer though a material to convert 'heat' into electricity.

A thermoelectric generator also known as a TEG, is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck or Peltier effect which is a form of thermoelectric effect. this type of generator is being used by NASA and the Martian Rovers to power without the uses of solar panels, because of how inefficient they are!

A level Maths

One of the most essential Maths lessons a student can have is on how to use a calculator. The students take these calculators into the exam without the knowledge of most of the functions, which could help them in the exams

Simulations

Sometimes simulations are a good idea to show a concept that can't be seen. But should you use computer simulations or instead is it better to have models and apparatus that the students can touch and play with. The latter although they take time to make seem to work much better

Dragons fire

 One of those fun experiments - producing dragons fire - the boron sparks off an exciting and interesting conversation on flame tests, identification of chemicals and fireworks.

Osmosis

Trying to find an isotonic solution for the chips. I have found that the chip cutter is excellent at producing chips of the same sizes.

Pasco Ultrasonic sensor

I probably use this @pasco ultrasonic sensor more than any other sensor in Physics. Other sensors come out for specific experiments but this one seems to be used in more experiments than any other and being wireless and having a good range  it is invaluable.
