1. the potential 1997—98 flu outbreak in Hong Kong and the work done around the clock to produce a vaccine,

2. the biological warfare possibilities in Iraq and the related political problems,

3. recent E. coli food poisoning outbreaks and the acceptance of irradiated meat in the food industry,

4. the renewed exploration of the Moon and the search for signs of water, or life, by NASA,

5. issues in conservation ecology and deforestation,

6. recent global warming and El Niño phenomena.

1. To display aesthetic wonder, show a slide of someone scuba diving around a colorful coral reef, or a similar shot.

2. To display scientific wonder, show a photo of beached whales, with a crowd of people or biologists surrounding them and attempting to understand what happened.

1. To display the theme on the origin of the universe, show recent slides from the Hubble telescope research (e.g. one recent one which showed two universes colliding).

2. A large color-coded DNA model, or picture thereof, would nicely illustrate the idea of large organic molecules constructed from many simple, repeated building blocks.

3. Show real fossils or pictures; for example, trilobites, insects embedded in amber, fern imprints, petrified wood, etc. (Figure 1.8).

1. Repeat the picture of a scuba diver exploring a reef, couple it with a picture of a modern research lab studying sea anemone behavior, and pictures, taken through microscopes, of cnidocytes, for example. Or, use a similar series of shots from macro to micro levels on some biological topic.

2. To emphasize bolded terms in this section, show a text slide with the bolded terms enlarged for emphasis: empirical, intersubjectively testable, naturalism, etc.

1. To demonstrate the Principle of Parsimony, an Occam's Razor discussion activity, or sample problem (e.g. why does the car light go on each time the door is opened?) could be presented.

1. To show emergent properties and compare them with the properties of constituents, show chlorine gas and discuss its toxic nature, show solid sodium and discuss its explosive nature, then show table salt (include the actual reaction between chlorine gas and solid sodium if possible) and discuss its nontoxic, nonexplosive qualities.

1. To illustrate differential rates of metabolism, show active and dormant organisms (e.g. a tree in summer, a tree in winter; a bear fishing in a stream, a bear sleeping in a den), and discuss how, in summer, both organisms are taking in or making food and, in winter, they are both using stored materials to survive.

1. Pass around or show several copies of the New York Times Tuesday editions, which have Science Times articles each week. Other editions of the Times, for one, also regularly have news coverage of science topics.

2. Show slides of various persons, including males, females, and various ethnic backgrounds and abilities, engaging in a wide variety of biologically related occupations.
