As a scientist, regardless of your field of expertise, most likely you will be required to write your findings and record your experiments.

Why not put this detailed writing discipline, combined with your creativity, to author a book.

The plot could surround your field of expertise and perhaps involve the murder of a co-worker.

The plot could develop in that it appears that it was accidental death, but you think otherwise due to mysterious discolorations or other abnormalities that indicate that it was a possible murder.

You could use your scientific background and education to draw upon and provide those types of detail that bring credibility to the writing.


2. Consultant

A possibility of earning some additional income would be to offer your expertise and services in the role of a consultant.

The answer could be in the form of a saltshaker.


Personal Story

Similarly, to most of you, high school was an opportunity to be exposed to a number of sciences.

In 10th grade, it was Biology, 11th-grade Chemistry, and in 12th grade it was Physics.

I enjoyed the sciences immensely and I particularly enjoyed chemistry and biology.

In fact, for Christmas one year I asked for a microscope as I was so enthralled with biology class and looking at cells, learning about our DNA and the various components of working within a laboratory.

Of course, a lot of the credit for that interest goes to the teacher that was teaching these subjects.

I don’t know if they were degreed in their particular science but their teaching, but they made it enjoyable, interesting, and memorable.
