Immutable theory of light

 Looking at light passing through one prism then taking just one of those colours and trying to split that light again in another prism. It doesn't get split any more. Red light stays as red light.

Heating effect of electricity

 #Physics Teaching about electrical circuits and resistance and heating. Setting iron wool on fire with only a few volts. The students wondered why I wouldn't hold the wool in my hands until they saw this. #iteachphysics #Science #STEM

Parallelogram of Forces

 Teaching #Physics online looking at the parallelogram of forces using a force board. Even though the students are back at school many are still forced to isolate or have Covid and then I need to teach them online. #iteachphysics #Science #STEM

Centre of Mass

 #Physics Using and inclined plane, a phone inclinometer and some masses with foam to raise the mass higher with adding any mass lower down to look at the effect of centre of mass, angle and the tipping point. Fun Experiment #iteachphysics #Science #STEM With the mass higher up the object falls over at a lower angle. With a shorter piece of foam the centre of mass is lower and the angle is much higher before the object falls.

Nylon Rope Track

 Some fun #Alevel #Chemistry carrying out the nylon rope trick. Seeing the faces on the students as the nylon is pulled from where the two surfaces touch and drawn out into a string. #Science #STEM #iteachchemistry

Inclined Plane

 #ALevel #Physics Theory and Practice looking to the inclined plane. Learning about Mg sin Ɵ and mg Cos Ɵ.

Seeing the equations, working them out and then finding the real world values are the same. #iteachphysics #STEM #Science

Interactive Physics

 #Physics Using Interactive Physics to demonstrate different physics concepts. Old software but works well for certain demos. Can measure using this then try it out in the real world and compare. #iteachphysics #STEM #Science
