We have always been taught that there are three states of matter - solid, liquid, and gas. These are the common states that are taught in school.
However, with advancements in science, there are now five states or phases of matter. Two more - plasma and Bose-Einstein condensates - have been added to the list. Check out the link to the article from Live Science.
Thank you for your observation. Maybe you will one day discover many more.
