For a scientific temper
You would have all heard about physics, chemistry and biology. But did you know that within these are various subdivisions that are called specialisations?
For example, biology has botany and zoology, which have more micro-specialisations. The same goes for engineering, environmental sciences and a whole bunch of other subjects. Sometimes these specialisations may even have connections with subjects like history, geography, psychology and others.
Here is a word search based on specialisations within science. See how many you can find out.
