Teaching Parametric Integration

Parametric Integration is not one of the easiest things to teach, but when the @Casio GC50 emulator calculator does different things to the real thing, then this makes life a bit more difficult

 

Thermopower

Discovering the power of electricity and volts! We wanted to know where those volts went? The answer is as heat, as demonstrated by @Lascells' Thermopower unit. #electricity #volts #heat #Thermopower

 

Chromatography of Chlorophyll

Which solvent works best to display various pigments in a green leaf? Experimenting with water, acetone, alcohol, and mixtures of acetone and alcohol, amongst other solvents to see which resolved the pigments the best. No real good answer in what we tried. #science #biology #experiment

 

Microprocessor lab

 Got out the ancient but still working HP microprocessor lab to show and teach the students. Some hand assembly made the programming interesting. Wonderful bit of kit and still being used for computing 40 years on. #vintagecomputing 

Separating Oil and Vinegar

 Who knew separating oil from vinegar would be so tough for students? I demonstrated how one layer sits atop the other, but they insisted on filtering, distilling, and even freezing it! None of them suggested using a separating funnel. #ChemistryStruggles #LabFails

Orbit Tellurium

Visited Cochranes of Oxford @CochranesOxford at #Bett2023Looked at a superb Orbit Tellurium, so had to order one!

Moments

Moments: A difficult concept to grasp but very easy to demonstrate and play with using the @pascoscientific metre stick and the mass hangers. Teaching this was a breeze.
