Pressure

 GCSE Physics Tuition: Investigating Forces and Pressure. Looking at the force and pressure of a stiletto heel. We looked at why I put some blutack on the table to protect it and what happened to the wood when I didn't. A good excuse for some of the ladies to show off their shoes.

Transpiration

 GCSE Biology Tuition: Having a go at investigating transpiration using a photometer. The hard part of this set-up is ensuring there are no air bubbles in the experimental setup except for the one in the capillary tubing. We then could alter the climate conditions and compare the rates of transpiration

Old style printing technology

 A-Level Computing Tuition: Dot Matrix Printer Paper and the Dot Matrix Printer were quite a shock to some students who had never encountered these before. They wondered how letters were ever produced on the daisy wheel printer. It was fun to see it in action.

Determination the MW of a volatile liquid

 A-Level Chemistry: Getting out the steam kettle to heat up a gas syringe to 373K then inject a known mass of a volatile liquid into the syringe and measure its volume  at 373K then use PV=nRT to calculate the number of moles for that mass and from that the MW

Press a button on a Pasco smart cart and they will explode apart

Synth Setup

 Setting up my synth to do some background music. I can use both a hardware and a software setup; sometimes, I use the software to make the hardware sound different. Still looking for that signature sound. One day, I might stumble across it.

Rates of Reaction

GCSE Chemistry Tuition: When covering revision for a test, nothing can beat the @pascoscientific colourimeter to create a concentration reaction curve this fast. In just 20 minutes, we had done 5 different concentrations of thiosulfate vs acid and got these results.
