Answers to Quiz

Purpose

The field of lighter-than-air aviation involves many areas of general chemistry. The purpose of this WebQuest is to reinforce many basic chemistry concepts by exploring the science of lighter-than-air flight.

General Chemistry Concepts

Most of the questions in this activity deal with either chemical reactions or the behavior of gases. A list of the specific concepts involved with each question follows.

Question	Concepts involved
1	Chemical reactions, stoichiometry
2	Octet rule, noble gases, chemical reactions
3	Avogadro's hypothesis, moles, gas behavior
4	Ideal gas law
5	Gas mixtures, chemical composition of air
6	Chemical reactions and reactivity, surface area, octet rule, scientific method, nature of scientific knowledge

Relevant National Science Education Standards

Unifying Concepts and Processes—Question #6 deals with the evidence used by Addison Bain to unravel the unanswered questions of the Hindenburg disaster, as well as how he modeled his hypothesized scenarios in the laboratory to test their validity. It also shows how he drew on many kinds of evidence to arrive at his explanation for how the tragedy occurred.

Physical Science—Chemical reactions and their endothermic or exothermic nature are discussed in the questions.

Science and Technology—The technology of lighter-than-air flight is the focus of the activity.

History and Nature of Science—The story of Addison Bain's investigation explores the nature of scientific knowledge and illustrates that science is a human endeavor.
