History: Argon was the first discovered of the noble gases! Argon was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay.

Argon is frequently used when an inert atmosphere is needed. It is used to fill incandescent and fluorescent light bulbs to prevent oxygen from corroding the hot filament. Argon is also used to form inert atmospheres for arc welding, growing semiconductor crystals and processes that require shielding from other atmospheric gases.

Class Discussion

I think that spectrum eating is a fabulous (and fun) approach to eating! For the most part you can ensure that you are eating a variety of nutrients, antioxidants, amino acids, etc.. My consciousness around food has been greatly influenced by various authors, activists, farmers, and my own participation in food justice/ sovereignty work.
