Testing for oxygen

 Making and then testing for oxygen. Fun of relighting a glowing splint in oxygen. #Science #iteachchemistry

Elodea Photosynthesis

 Using one of the photographic lights to really illuminate some Elodea getting it to produce significant amounts of Oxygen. Doing this experiment in the winter means little sunlight and its harder to get Elodea. #Science #STEM

Electricity and Magnetism

 Plotting the magnetic field around a single wire. #iteachphysics

Making salts from insoluble carbonates

 Making Salts from Carbonates. A good time to learn about magnetic stirrers and how they work. #Science

Equilibria

A Level Chemistry looking at Cobalt Chloride in hot and cold solutions and how the equilibrium is changed #iteachchemistry #Science

Red + Green = Yellow

 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

Ammonia and HCl

 Doing the safer way of showing the reaction of Ammonia with HCl. The relative size of the molecules can be appreciated more. #Science
