A different kind of Maths

 Why do we learn Maths? - so we can do Physics, of course.

Rubens Tube

 Always a class pleaser when I demonstrate the Rubens tube. Even more fun when we link it up to a student's phone, and they play their favourite soundtrack. Explaining how it works demonstrates how sound travels through the air much better than other ways of teaching.

Aphids

Aphids in A-Level quiz stirring debate! Some students stumbled over their life cycle and feeding mechanisms under phloem pressure. Not familiar with these intriguing insects? Brush up on your biology! 📚🔬 #BiologyExam #Aphids #AlevelBiology

 

Bourne End 2023 Sailing

 Bourne End - Upper Thames Sailing club regatta @upperthamessc

Took some 3000 photos and about 8 hours of video. Now to process this lot.

Typical week

Variety is what a typical week looks like. For some, there are loads of revision and test papers, while others are investigating Rubens tube, or doing a required practical, making up solutions, or carrying out electrolysis, either online or in person.

 

Thermal expansion making up solutions.

 When making up solutions - why is the temperature so important. Students made up a solution of NaOH to the correct molarity, then after cooling, they saw that their perfect solutions weren't so perfect after all. Lesson Learnt.

Plancks Constant Apparatus

The last two LEDs on the Plancks constant apparatus are in the IR and invisible to the naked eye but easy to see with a phone or a digital camera. Should we use the camera to obtain readings for these values, as the camera might give different weights to the human eye?
