Natural phenomena, such as rainbows, sunsets, flashes of lightning, waterfalls, geyser bubbles (appearing just before the water is ejected from the ground) and geysers themselves, volcanic eruptions, and solar eclipses, provide a context for teaching a wide variety of science concepts and ideas. These phenomena, with the use of technology (i.e. high-definition photographs), can become sources of both aesthetic pleasure and wonder. On the other hand, some very spectacular phenomena, such as aurora borealis and light pillars (forming around natural sources of light, such as a setting Sun and Moon, and caused by suspended ice crystals), or phenomena that are terrible, such as tsunamis, tornadoes, and fire tornados (created by vortexes that suck flames upwards) and volcanic lightning (when the volcanic ash gains electric charge), can literally catch the students’ attention and evoke wonder and awe.
