| Summary: | Trainee teacher Emma Bradley is shown a series of nine quick-fire exo- and endo-thermic reactions by Dr Kay Stephenson from the Royal Society of Chemistry and Simon Quinnell of the National Science Learning Centre, York. The demonstrations have been chosen to highlight various aspects of chemistry such as rates of reaction and energy changes, e.g. the catalytic oxidation of ammonia and the reaction of potassium manganate (VII) and glycerol. All the reactions have been assessed as safe to carry out in the classroom by CLEAPPS and Emma hopes some real life chemistry will enthuse and inspire her students. With each demonstration she also gets some helpful tips on how to carry out the demonstrations safely and successfully in her classroom. Explosive experts Dr. Jacqueline Akhaven, senior lecturer at Cranfield University, and Research Officer Dr. Alex Contini explain the explosive chemical and physcial reactions behind the spectacular fireworks we all love to watch. They do this through a series of controlled explosions in the Military Research Laboratories of the Ministry of Defence. You won't see any of these demonstrations in any classroom because they re much too dangerous. Jacquie and Alex begin with gunpowder, the basis of all fireworks, and explain how it reacts. They also demonstrate why many modern stage and TV effects use flash powder instead of gunpowder as it is more efficient. They change the colour of a firework by adding a metal salt and heighten its effect by adding a whistle and a scream. Finally, they open up a rocket to identify and predict what an identical rocket might do when ignited. And they re spot on - the rocket behaves exactly as planned. Beware, this can't be done outside the lab. |
