PBS has made some of its NOVA and Frontline programs available online: NOVA Online Frontline Online I watched "Life's Greatest Miracle" last night, which is about human sexual reproduction (It is a remake of the older "Miracle of Life" video). It was excellent; though I wouldn't want to show the extended bikini-babes-on-the-beach scene in class. …

Earth as art
"And God saw everything that he had made, and behold, it was very good." -- Genesis 1:31 I'll let these images from NASA's Earth As Art site speak of the beauty and goodness of God's Earth: Grace and Peace
Wild World
At the middle school and high school level, biology textbooks usually have a section on biomes, which are large regions of the Earth that have distinctive communities of plants and animals. Examples of biomes include desert, tropical rainforest, temperate grasslands, and tundra. These biomes can be subdivided into smaller ecoregions, which have more specific assemblages …
Stellarium
For several years, I have been using Starry Night software in the classroom when teaching about the stars. The students love it, but at $49.95, they were unlikely to be able to do anything with it at home or in our computer lab. I found an excellent substitute for free on the internet: Stellarium. There …
Alaska Volcano Observatory
The US Geological Survey operates five volcano observatories, which keep watch on regions of volcanic activity in the United States. The five observatories are for the Cascades, Hawaii, Yellowstone, Long Valley (in California) and Alaska. My web site of the week is for the Alaska Volcano Observatory. Here's a description of the Alaska volcanoes from …
The Inner Life of the Cell
Web site of the week: "The Inner Life of the Cell." This site has a computer animation of the inner workings of a white blood cell. Absolutely amazing—both in terms of the animation, and the processes it portrays. It is a testimony to the wisdom and power of the Creator. I got this link from …
eNature — Online Field Guide
A good online field guide—with images and information about 5500 different species—is at eNature.com, which is produced by the National Wildlife Federation. With sections on birds, mammals, reptiles, amphibians, fish, insects, spiders, seashells, wildflowers, and more; eNature is a good site for those of us who don't have a complete shelf of field guides (I …
Google Earth
It's time to get back to my "Web Site of the Week." I'll start with one of my favorites, Google Earth. Google Earth is software that you can download for free, which can be used for viewing imagery of virtually all of the Earth's land areas. Resolution tends to be better over the United States …
White Horse Inn
In Bucharest, we attend a Romanian-language church, and often don't get all that much out of the sermons. When we need a dose of solid English-language teaching, we download a John Piper sermon from Desiring God. My favorite radio program is The White Horse Inn, produced by the same people who put together Modern Reformation …
The Periodic Table of Comic Books
Welcome to The GeoChristian. Out of over 600 posts on my blog, this one on the Periodic Table of Comic Books is in the top five in terms of how many people view it. The purpose of The GeoChristian is twofold: 1. To enhance science literacy within the Evangelical Christian community. 2. To present a …
The Evangelical Ecologist
For my web site of the week: The Evangelical Ecologist, subtitled "A Christian Ecoblog- 'Cause the world isn't ours to mess up. Psalm 24:1." This week there have been excellent posts about the high price of gasoline, and the economics of sustainable development. Grace and Peace
Urban Legends
Hopefully there is no need to tell you, but wild stories circulate on the internet—on web pages and via email. My web site of the week is Snopes.com, which is devoted to uncovering the truthfulness or falsehood of these "urban legends". What would make one suspect that a story received in one of those emails …
Beauty in Stone
For the web site of the week, I have chosen Igneous rocks in thin section. In order to identify minerals and interpret the history of a rock, geologists will often make a thin section. A thin section is made by slicing and polishing a rock until it is only about 30 micrometers thick (human hair …
Simple Cells?
Prominently displayed in the back of my science classroom at Bucharest Christian Academy is an oversized poster showing biochemical pathways—the enzyme-mediated processes that occur in all cells, in organisms ranging from bacteria to humans. The poster presents an incredible amount of information, outlining processes such as electron transport in the mitochondria (in eukaryotes), and the …
Botany Photo of the Day
Astronomy Picture of the Day has been a favorite of mine for some time. There have been several other attempts at "Science Picture of the Day" sites, but they have all fallen short, at least in my mind. Botany Photo of the Day, however is an excellent site, with a beautiful image from the world …
