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.

Electric fields

A problem for the students having to explain how electricity works by visualising the electric field around a wire and seeing and measuring the magnetic field using the @pascoscientific magnetic field probe. Are the fields the same but just looked at differently?

 

Tree Diagrams

 By far, the best way of teaching tree diagrams is with sweets. After the first round, if you have eaten a green sweet, how many left becomes easier when it is the mouth.

Specific Latent Heat of Vaporisation

Ready to perform the Specific Latent Heat of Vaporisation experiment. The older style immersion heaters were shorter, but my replacement one is too long and doesn't give accurate results.
