We talk water and sewage - who invented the toilet, why water disposal is so important, and make sure you shower before you swim!

We talk careers and paper rounds with Mr Forsyth, Atkinson and Young focussing on the importance of #nowrongpathway, skills, resilience and growth mindset.

Tennis is an interesting subject for science as it is hugely dependent on materials (racquets, courts, balls) but would tennis players be any better if they knew more physics?

A German word meaning ‘environment’. But also that different species, with different dominant senses, perceive the world very differently to us. We do our best to discuss what these are and how perhaps we could be less human sense-centric!

We try to add our thoughts on the TV show ‘Breaking Bad’. They have used science experts, what can we add to the discussion?

Hear from Ricky Sheriff-Short as he describes his journey from an inauspicious academic end to school to working with 15,000 nurses after an interactive and fulfilling nursing career. When Ricky says ‘bank’ he means a nursing bank, not a bank bank! ;-)

Scales are useful for relative measurement - so pH 1 is more acidic than pH2 by a factor of x10 concentration hydrogen ions. Similarly, 20decibells is 10x louder than 10decibells. But what about your stools? On a scale of 1 to 7 your stool can be used to tell whereabouts you are more constipated or have diarrhoea. Awesome.

We discuss rockets, fuel, the proposed base on the moon and travel to Mars. Radiation, dummies and Shaun the sheep. As ever, we’re not experts, it’s a starting point for discussion…for example, the solid fuel rocket is used second not first! …and we don’t know if it is (insoluble) aluminium oxide poisoning the aquatic life around the launch site.

What units of measurement should we use, and which ones do we commonly use? We discuss the metric system, Imperial units and odd ones used on the news…. Like Wales!

Second series - up and running with the usual expert insight and occasional ignorance. But, always discussion.
