‘Useful Chemistry’ for Year 9 Science
Last week, Year 9 Science students conducted flame tests as part of the ‘Useful Chemistry’ unit. They discovered that some metallic salts burn with distinct colours (e.g. Strontium turns the flame colour to red, Copper to blue/green and Potassium to purple). They then discussed the real life application of this chemistry to make spectacular fireworks displays and the significance of this experiment in leading the Scientist, Neils Bohr, to develop the planetary model of the atom.
I think they also enjoyed making their own pyrotechnic displays!
