Modern Webpage Design

 The computing books look at Web pages designed using Notepad, which is what I taught 30 years ago. We looked at more modern software like Nicepage and others to create webpages that do all the clever things and how much web pages have changed through the years.

Electric Fields

Creating parallel and radial electric fields from a Static electric feed rather than an EHT device. It works better.

 

Fractional Distillation of Oil

Starting with Synthetic Crude Oil the students heated the oil progressively heating it to a higher temperature and collecting the fractions. The first fraction burnt but the subsequent ones apart from the last wouldn't burn.

 

Pressure inside a ballooon

 Is the pressure inside an inflated balloon greater than that in a deflated balloon? The debate raged on until with a @Pascoscientific wireless pressure sensor proved that the pressure was indeed 1.1 KPa higher in the inflated balloon - the elasticity of the balloon to blame.

Curves

 Now draw a nice smooth curve through all the points

Static Electricity to Direct Current Demo

 A good fun experiment taking the static electricity from a Wimshurst machine and passing this to a capacitor plate and using a graphite-covered ping pong ball to transfer the charges which can then be picked up on a beam galvanometer.

Biodiversity

Thank goodness some councils in England are seeing sense in biodiversity. The councils are starting to leave large areas of parks to go more native, and as a result, there is a burst of biodiversity coming along.
