A statement of a learning objective contains a verb (an action) and an object (usually a noun). The verb generally refers to [actions associated with] the intended cognitive process . The object generally describes the knowledge students are expected to acquire or construct. (Anderson and Krathwohl, 2001, pp. 4–5) The cognitive process dimension represents a continuum of increasing cognitive complexity — from remember to create.

Neil deGrasse Tyson: Maybe Were Not As Smart As We Think We Are
Imagine a circle that contains all of human knowledge: By the time you finish elementary school, you know a little: By the time you finish high school, you know a bit more: With a bachelor's degree, you gain a specialty: A master's degree deepens that specialty:
A spatial representation of every star within 14 light-years of the Solar System in orthographic projection. There are 32 stars in this region, including the Sun. The stars are colored according to the spectral type, which may not reflect the actual color.
From the nanoworld to the universe — The worlds we measure using our infinite yardstick. Nikon's opto-electronics technologies let people explore realms beyond the range of the naked eye. In this presentation, you can see the relative sizes of objects arranged on a single scale. This lets you grasp the sizes of things that you cannot compare side by side in the real world. Today's electron microscopes and astronomical telescopes reveal objects that were invisible to people of the past. How is your grasp of the sizes of such things?

by John Walker January 4, 1994 Fly's Eye The University of Utah operates a cosmic ray detector called the Fly's Eye II , situated at the Dugway Proving Ground about an hour's drive from Salt Lake City. The Fly's Eye consists of an array of telescopes which stare into the night sky and record the blue flashes which result when very high energy cosmic rays slam into the atmosphere. From the height and intensity of the flash, one can calculate the nature of the particle and its energy.
by Isaac Asimov I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important.
The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five dollar bet over highballs, and it happened this way: Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face -- miles and miles of face -- of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole. Multivac was self-adjusting and self-correcting.
