Metal Chloride Experiment Evaluation
The experiment that we did today involved a range of different metal chlorides and a bunsen burner. We lit the bunsen burner and put the different types of metal chloride on a long piece of metal to hold above the flame. We had Copper Chloride, Potassium chloride, Strontium Chloride and Sodium Chloride. All of these different metal chloride reacted differently to being held above the flame from the bunsen burner. We had a google doc to record our objectives subjectives, observations and inferences.
I don't think that this is a very good representation of the science of stars because the experiment is very inaccurate. Stars change colours based on their temperature. When the star is hot it is blue colour, when it is cold it turns red. We weren't able to find the temperature of the flame when burning the metal chloride so we couldn't identify wether when the flame was blue it was hotter than the red flame.

Some of the strengths of the experiment is that it does show two of the colours that stars could shine.
