Hemel Private Tuition

It was the first time I had done Charles Law using a dried capillary tube and a bead of conc Sulfuric Acid to determine the volume against the temperature. The experiment took 3 hours, but I now know how to make it faster to fit into an hour lesson. Jacques Charles made a major contribution to th...

I confused many of the students with the paraffin block puzzle. The bottom is dark, the top light. Turn is round anyway, and the bottom is still dark. It kept the students amused for quite a while whilst they tried to work out what I had done to it.

After many months of waiting for my @Pascoscientific Wireless Geiger Counter and stand to arrive, I particularly like the stand, being able to place sources at different distances and placing different thicknesses of different materials to absorb the radiation.

Diffraction of light using a laser going through a single pinhole in a piece of Aluminium foil. I like introducing a topic by demonstrating an effect or, better still, letting the students do their own demo and then letting them come up with an explanation of what is happening. The light spreads ...

Comparing the burning of different alcohols by colour and rate of burning. It's always interesting when asked to compare substances. The students usually suggest taste - then they read the bottle labels.

Teaching topics like Bluetooth can be tedious - so spicing this up a little using the Bluetooth Go Dice. We can get the values, and the orientation of the dice, whether they are being rolled or not and then we can program them so we can count the total or change the values.

Negative feedback is a difficult concept to try and get over, so I tried using a balance board and the @pascoscientific smart cart strapped to my chest using the accelerometer to show my movement in the X Y and Z axis as I tried to keep my balance. The students did better than me

Density determination with a few extra challenges like an irregularly shaped piece of polystyrene, warm liquid gallium, and a hollow metal box

Using the Casio fx-50 to draw graphs of the trig functions and using the value on another graph so that the intersection can be found and then the value displayed. Better for understanding than using the CAST Diagram and the standard calculator
