Spectrometer with Fibre optic scope

 One of the problems of the students using a spectroscope to observed the emission lines is that they usually can't see them, but using the @pasco spectrometer I can put the image on the board and we can calculate the limes easily

A Far Infrared Picture

 My Phone with a FLIR attachment allows me to take and show heat pictures to the students, showing the shadow of a hand print on a table of how much heat the white board gives out.

Faradays ice Pail

 More fun with the Van De Graaff Generator this time with Faradays ice Pail #iteachphysics

Black Light

 

Using a UV light to show up the invisible parts of bank notes enthused the students some claiming they hadn't seen a £50 note before and seeing that it was genuine. I was glad all the notes we looked at were genuine.

electrical conductivity

Busy day today with lots of experiments including using the @pascoscientific electrical conductivity meter to look at different salts and how their conductivity varied. Students thought best part was using the vortex mixer.

The Van de Graaff Generator and a Ping Pong Ball

The graphite covered ping pong ball moving charge from one sphere to another and making the little hair I have stand on end. The ping pong ball acts as a charge carrier allow the Van de Graaff generator to discharge, but the sudden discharge has a lot of force behind it, launching the ping pong ball away towards the smaller dome. #iteachphysics

Polarising lenses

Using polarising lenses to see the effect on light and effect that some solutions have on the light passing through. #iteachphysics
