Covered in Fire

There are different colors of fire because of the different types of chemicals and elements put into the liquid for the start of the fire. These liquids also change the amount of heat for the fire and that is what makes the different colors. The different colors include red, orange, yellow, green, blue, and purple.

This relates to engineering because the heat and the chemicals are all part of chemical engineering. The substances used to light fire and the actual chemicals to do so are part of that subject too.
