In the model shown at right the Sun and hypothetical regions around it are labeled.

Heliophysics is the physics or astrophysics of the closest star to the Earth. It is a lecture from the astronomy department. This is a quiz based on this lecture that you are free to take at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the astronomy resources template. 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.

A suggestion is to 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 from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. True or False, A basic unit of length for measuring the diameter of the Sun is the kilometer.

TRUE
FALSE

2. True or False, By assuming gravity causes the Earth and Sun to orbit each other, and assuming a mass for the Earth, a mass for the Sun can be determined from the orbital characteristics.

TRUE
FALSE

3. True or False, By correlating the length of an Earth year to a fixed number of seconds, the length of time of a second can be determined.

TRUE
FALSE

4. True or False, The Sun could have an internal core of iron that generates its bipolar magnetic field.

TRUE
FALSE

5. True or False, As the principal portion of the sunspot cycle corresponds well with a periodic conjunction of Venus and Jupiter, the increased electron flux to the Sun may cause the magnetic poles to reverse.

TRUE
FALSE

Your score is 0 / 0

Research

Hypothesis:

  1. Timing the Sun is like timing a ball of gas.

Control groups

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]
