The following experiments and demos investigate the effect of the greenhouse gas carbon dioxide in
i) our atmosphere
In this demonstration, the basics of the electromagnetic spectrum are first covered followed by a demonstration of the thermal infra red. The final demo shows the effect that the greenhouse gas carbon dioxide has on our atmosphere as it absorbs thermal infra red radiation.

This demo allows you to create an edible analogue of a carbonaceous asteroid akin to the Moons of Mars or the parent of the carbonaceous meteorites. This simple demo has the wow factor and is suitable for both family shows and is a good finale for a space-themed masterclasses. This demo is successfully delivered as part of University of Leicester open days and planetary science outreach programme. In addition it is delivered during family shows and events at the National Space Centre, Leicester.

I have made an instructional video on how to make Asteroid Ice Cream. This was filmed during an A-Level planetary geology masterclass for the 2013 Astrobiology Summer Academy at the UK Centre for Astrobiology.
This activity was developed with funding from a UK Space Agency Space for All grant 2012/13.
This activity helps you understand how clouds and tornadoes are formed – you get to make a cloud in a bottle and a tornado in a bottle.
These activities were run as part of the University of Leicester EOS Blue Marble outreach programme to KS1 and KS2 in primary schools along with the Weather Forecasting activity. These activities were also run during 2013 BBC Star Gazing Live East Midlands Event and 2014 Leicester Star Gazing Live.
