Using the @pascoscientific colourimeter to demonstrate the rate of the reaction of Sodium Thiosulfate and Hydrochloric Acid. Probably one of the best and easiest ways to demonstrate the effect of a change of concentration on the rate of a reaction.

Mechanics in A-level Maths for non-physicists is complex. So, in the Maths lessons, I need to get out an inclined plane so they can see and, if necessary, measure the forces, making understanding the Maths easier.

Water Flow Meter
I have the water flow meter back all working again, so Paul and I went out to test it in the River Gade, which has burst its banks. A flow rate of 1.31 m/s at its highest flow rate in a narrow channel at 300mm.

Phases of the moon
Teaching all about space and looking at what causes the moon's phases. Surprised by how many students didn't know and how most living in the city had never seen stars or the Milky Way. One said that the Milky Way didn't exist because he had never seen it.
