Tug-of-War
It encourages students to reason carefully about the "pull" of various factors that are relevant to a question of truth. It also helps them appreciate the deeper complexity of matters of truth that can appear black and white on the surface.

It can be used in any situation in which questions of truth come up, and there is evidence to be considered, evidence from common knowledge or from information resources like newspapers or encyclopedias or the Internet. Questions of truth can come from school subjects or everyday life. Newspaper headlines are full of claims from politicians and others that can be evaluated. Science brings many issues like whether genetically engineered foods are dangerous or how old the universe is. History comes with endless controversies, for instance about who really started a particular war or what everyday life was like at various times in the past. Many works of literature create suspense by offering only bits and pieces of information until the end: Before the end, can you the reader figure out who the culprit really is or what secret from the past the heroine is hiding?

Summary [Word]
PZ Visible Thinking: Tug-for-Truth [Web Link]
  * This is a routine that builds on children's familiarity with the game of Tug of War to help them understand the complex forces that "tug" at either side of a question of truth (there is also a Tug of War for fairness dilemmas with the same basic structure).
* The routine uses a rope or a diagram to represent pulls toward true or false in evaluating a claim. The tug of war is between True and False.
* Help students think about the various factors that tug at one side of the rope orthe other, as well as other considerations related to the issue.
* A natural follow-up to the activity is to have students investigate facts related to the questions written above the Tug of War.
