Alkali Metals

Watching how fast Sodium oxidises in the air before comparing its reactivity to Lithium and Potassium in water. A really great, fun experiment.

 

Chemistry - Fuel Cells

 This is still the future - fuel cells. Charged by Solar to split water. The hydrogen and oxygen combine at a later time to create water again and electricity. This cell will do both the splitting and the recombining.

Hookes Law Series and Parallel

 Back to work looking at Hookes Law with series and Parallel springs and predicting what happens and then trying out experiments to see if the experiments prove the predictions.

Survived Christmas

 The proper use of a NO2 cylinder making whipped cream for a vanilla slice - part of Surviving Christmas 2023

Analog Computing

 Time to set up and play with a few more demos of using Analog Computing @analogparadigm to demonstrate what it can do and achieve.

Last Day of Teaching before Christmas

 Last day of Teaching until after Christmas. I can manage to squeeze in a few days off to celebrate Christmas with my family. But before then, it's Chemistry, Maths, Biology, Maths and Computer Science.

Splint flame tests

 Flame tests are always a good way of finishing a term's experiments. There are many ways to do flame tests, but one of the easiest is to use a wooden splint. It's quick, easy, and fun.
