In which Stream i would take in my higher studies to became a scientist?

Hi,

There are many different ways to get into science. The scientific community has a place for everyone, including the total novice. If you're interested in science, the best place to start is by learning as much as you can. Aside from classes and books, there are magazines that explain recent scientific findings to a popular audience (such as Discover, New Scientist, and Natural History) or, if you feel up to it, you can even try the scientific journals at your library (Science and Nature are two well-respected options). But science isn't just about book learning; you can get involved in the activities of science in many ways:

• volunteer at a nature or science center


• work with a non-profit that promotes science


• attend a science cafe (where a scientist gives an informal talk about his or her work)


• try out a summer science program


• ask to shadow a scientist on the job


• explore the natural world on your own — after all, science is all around us

Typically (though not always!), scientists who want to run their own research continue their studies to complete a Masters degree, a Ph.D., and possibly a postdoctoral research appointment (commonly called a postdoc), which provides recent Ph.D. recipients with advanced training under the direction of a mentor).

Good luck in your choices!
