I have been doing the “wrap up” session for Vacation Bible School this week, and I have been using chemistry experiments to illustrate the lessons. Tonight’s lesson was about how Jesus died for our sins. It was a real challenge coming up with a chemistry experiment to illustrate The Atonement, but here’s what I did:
In a 250 mL Erlenmeyer flask, I dissolved a small amount of corn starch in 150 mL of water. I then added a small amount of potassium iodide. The result was a slightly cloudy, but mostly clear solution.
In a 50 mL beaker, I made 40 mL of a saturated solution of sodium thiosulfate.
I then filled a medicine dropper with bleach.
The Erlenmeyer flask represented a person, and the bleach in the dropper represented sin. I added a few drops of bleach to the flask, which turned blue. The color change represented the effect of sin. As I added more drops, the color got deeper.
I then showed the kids the beaker, which represented Christ. He lived a sin-free life, which is why the solution was clear. I poured the clear solution into the colored solution that was in the flask, which represented Christ coming into a person’s life. When the two solutions mixed, the deep color went away, and the result was a solution that looked like what was originally in the Erlenmeyer flask – a slightly cloudy but mostly clear solution.
I was reading Dr. Hunter’s blog yesterday, and he had a post about entropy and evolution. In that post, he cited an article that comes to the right conclusion on the issue, but for the wrong reason. In fact, I am surprised that it passed peer review, since it promotes a very bad misconception regarding the Second Law of Thermodynamics. Because both creationists and evolutionists do a very poor job of applying the Second Law of Thermodynamics to the concept of origins, I thought I would try to explain the proper way to interpret the Second Law of Thermodynamics. In the next post, I will then apply the Second Law to the concept of evolution.
Before I get started, however, let me tell you the overall conclusion. The Second Law of Thermodynamics DOES NOT forbid the process of evolution. I know there are many creationists out there who claim that it does, but they are simply wrong. In addition, I know there are a lot of evolutionists out there who claim that it doesn’t, but they do so for reasons that are often wrong. So let’s talk about the Second law of Thermodynamics and how to properly apply it to many situations, including the process of evolution.
Alkali metals (like sodium) really like to give up their last electron. That way, they have a very stable electron configuration. Well…one way these metals can give up their electron is to react with water:
2Na + 2H2O –> 2NaOH + H2
In NaOH, the sodium is in its ionic form, Na+. Thus, it has lost its last electron and is now quite stable. Note that hydrogen gas is a product. Well, hydrogen is an explosive gas, and this reaction produces a lot of heat. So when sodium and water react…
Note that this was done in a drainage pond with the owner’s full permission. There were no fish in the water, and the byproduct, NaOH, is actually good for the soil in this area, as the soil is acidic. Thus, this is an environmentally friendly shenanigan.
It turns out that of all alkali metals, sodium is the SECOND LEAST reactive. Lithium is the least reactive. The other alkali metals, in order of reactivity, are potassium, rubidium, cesium, and francium.
You have stumbled across Dr. Jay L. Wile's Blog. Dr. Wile holds an earned PhD from the University of Rochester in Nuclear Chemistry. He is best known for the "Exploring Creation with..." series of textbooks written for junior high and high school students who are being educated at home. He has also just released an elementary science series!You can read about that here.

Answers in Genesis
While I disagree with some of the theology on this website, the science discussed is pretty solid.
This website contains works from a good mix of young-earth creationists.
This is the blog of Dr. Todd Wood, one of the leaders in baraminology. He covers current topics of interest to young-earth creationists.
This is the blog of Kevin Nelstead, an old-earth creationist geologist. He covers many topics related to the age of the earth and offers a nice contrast to the young-earth writings listed above.
An interesting "think tank" that contains the major players in Intelligent Design
This is atheist PZ Myers's blog. While I disagree with most of what he says, he is a provocative writer. This is one of the few blogs I read regularly. Please note that there is a lot of foul language in his writing. Those who cannot defend their positions rationally tend to descend into such nonsense.
