Burning Magnesium Ribbon

 Year 9 Chemistry Tuition. Burning magnesium ribbons in the air is one of my favourite experiments. This is the most talked about experiment in school science because the students can do it themselves.

Pressure in a balloon

 GCSE Physics Tuition: Is the air pressure higher in an inflated balloon than outside air pressure. I had the whole class betting against me and they were wrong. The air pressure was the same - then we had to work out why. Using the @pascoscientific pressure sensor.

Polar Coordinates

In A-Level Further Maths Tuition, we played around with polar coordinates and used the Casio CG50 calculator to graph some of the equations we studied. Experimenting with different values, the students could see the effect on the shape of the graph.

 

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
