How an Oscilloscope works

 There was a time when students had met CRT screens but now with LED this and LED that they have little experience of seeing these let alone knowing how they work. when I showed them a valve they had no idea.

Proteins and Evolution

 Why do some proteins and reactions work the way they do? RuBisCO was probably created when Oxygen levels were lower and Carbon Dioxide Levels were higher, and there were not strong enough evolutionary pressures to create something better.

Changing Standards

 We looked at how standards in computing have changed, how Serial and Parallel came and went, and how firewire was a thing. We also looked at how cards for cameras and others have changed and adapted over the years.

Titrations

Students are getting lots of practice on how to do titrations. They are attempting to get single drops and very similar values on each repeat.

 

Spirometer

 

Completing one of the A-Level PAGs investigating breathing using a @pascoscientific spirometer. Measuring the vital capacity as well as the tidal volume. Trying this out before, during, and after running on a treadmill.

Online Maths Revision

 1:1 online Maths Revision hits the spot. The student comes in not being able to do something and, in the end, can do it. Soon, the students run out of things they can't do and have to get a good grade. So far, all the students have told me how easy the exams are!

Determining Density

 Going through all the physics practicals as revision just before the exam. How many can be done in a session? All 4 in an hour running concurrently. Determining density was one of the quickest.
