Metallic Structure Model

 A Petri dish, some water and washing up liquid, a straw and a pipette tip and with a gentle blow we have a model of a metal.

Calcium Oxide reacting with water

Adding water to the Calcium Oxide to make slaked lime and a lot of heat. The lump in the middle is the bit that didn't react that upset the figures.

Limestone experiments

Heating Limestone intensely to make Calcium Oxide, thermal decomposition. Weighing before and after showed a slight decrease in mass. Not as much as the students predicted until they did the next experiment
 

Fuel cells

Setting up and running a fuel cell to make hydrogen and oxygen and then reversing the fuel cell to make electricity. We made the electricity either by wind or solar power to split the water

A level Maths

 Amid the Prime Minister changing and a beloved Monarch dying and a new King Proclaimed, A level Maths continues unchanged

Installing and using VNC

 A challenge for the students. To obtain a screen capture from a Linux Machine on a Mac or PC. They decided on VNC but had to download and install all the software to get to to successfully work on the end.

Reducing Copper oxide

 @ChemixLab diagrams make it quick and easy to create chemistry diagrams to illustrate how to set up equipment for students, then they can piece together the things necessary to do the experiment
