Experiment

Today in aliens we did a experiment in the lab.

For our experiment we burner 6 different metal chlorides using the bunsen burner. Each different metal chloride caused the flame to turn a different colour, but before we used the metal chlorides we turned a little silver thing on the bunsen burner until the  flame turned blue. after each chloride we had to tap off the excess chloride on the wood that was placed under the bunsen burner. The 6 chlorides that were used were copper, lithium, magnesium, sodium, Potassium and strontium. If you use a special type of telescope you will notice that the stars aren't actually white, The stars you see at night are colours depending on the temperature of that star, The hotter stars will appear as blue or white but then the colder stars are red. The blue or white stars are 6,000-7,000k but the red stars are under 3,500k.
