Physics is watching the surprise on students faces when you mix red and green light and get yellow ... and they won't believe you saying it is a trick. These are A level students. #iteachphysics

Ores
Making Copper from its ore. Looking at a piece of native copper found in Cornwall and some real Malachite ready to crush up and make copper. Making it more real for students. #iteachchemistry #Science #STEM

Wave Energy
We see waves all the time but it takes a machine like this to show that the particles in the wave only go up and down and its the energy that moves along. #iteachphysics #Science #STEM

Reversible Experiments
Making experiments reversible Looking at Hydrous and Anhydrous Copper Sulfate. I was surprised when the students found out we to repeat this experiment over and over again without loss. #iteachchemistry #Science #STEM
