Transuranic minerals is a lecture and an article from the school of geology. It is about solid, crystalline substances containing the transuranic elements of the periodic table that occur in and compose astronomical objects. It focuses on materials that may occur on the surface of or associated with some astronomical objects.

You are free to take this quiz based on transuranic minerals at any time.

To improve your scores, read and study the lecture, the links contained within, listed under See also and External links, and in the astronomy resources and geology resources templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information using more familiar points of view, or be creative with association.

Enjoy learning by doing!

Research

Hypothesis:

  1. Transuranics may be found in rocks and minerals where heavy elements including actinides occur.

Control groups

This is an image of a Lewis rat. Credit: Charles River Laboratories.

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
