Deer Heart Dissection
My anatomy students learn the heart every year which ends with the dissection of a preserved sheep heart. This year, a hunter friend brought me a fresh deer heart which I was able to dissect in front of the class to show my students how the deer heart compared to the sheep heart. There isn’t…

Chi Square Analysis
The new Advanced Placement Biology curriculum includes a few topics on statistical analysis under the section on Science Practices: “Students can use mathematics appropriately.” Most introductory level biology classes (freshman) do not include these lessons because it can be difficult with students who haven’t advanced very far in algebra. Seniors in AP Biology should…

High School Students Doing Field Biology
If you are fortunate enough to teach near a university, there is a very good chance that programs at the college are in place to help high school teachers. For years, I have been able to borrow equipment from Southern Illinois University and Washington University to alleviate the costs of buying the equipment for…

Human Immunodeficiency Virus (HIV) Coloring
The virus that causes AIDS (Acquired Immunodeficiency Syndrome) is called the Human Immunodeficiency Virus, commonly known as HIV. HIV is a member of the retrovirus family, which means it contains RNA as its genetic material instead of DNA. HIV coloring worksheet uses a model to understand viral transmission. Students identify and color the major structures…

Why I Teach Pathology in Biology
When you examine the AP Biology Course Description, there is no mention of pathology (the study of diseases) in the list of Big Ideas. Bacteria are mentioned in the context of comparison between prokaryotes and eukaryotes, lines of descent, and endosymbiosis. Viruses are mentioned within the context of genetics and how DNA can be transferred…

Precision Versus Accuracy
I was in the market for a new digital scale, mainly for the osmosis experiment where students must weigh dialysis tubes. I found that my one digital scale just wasn’t enough for 20 students to gather data. Unfortunately, digital scales you buy from scientific suppliers are often very expensive and I really don’t need the…

Teaching Evolution Using Animal Models
Most evolution units start with a history of evolutionary thought, where scientists of the past, like Darwin, Linnaeus, Larmarke, and Wallace, are discussed with regard to their contributions to evolutionary theory. If you’re not careful, you can end up spending too much time on the history, talking about the Voyage of the Beagle and the…

Your Inner Fish – Video from HHMI
At the NSTA Conference in Chicago last year, I had the pleasure of meeting (at least from a distance) Neil Shubin, who is a fish paleontologist. We watched one of the newer movies, were treated to refreshments and popcorn and were given a t-shirt and a DVD copy of “Your Inner Fish.” This amazing…

Can Bacteria Be Designed to Create Gasoline?
I’ve heard the term “biofuel” before, and that usually conjures up images of corn fields and ethanol. I recently attended a lecture at Washington University presented by Fuzhong Zhang. The title of the workshop was quite intimidating: “Synthetic Regulatory Systems for Dynamic Metabolic Pathways.” Teachers don’t just spend our summers lazing about at the pool!…

Is Group Work Really Effective?
I was out for a day last week and left a case study for my anatomy students. The case was about six pages long and starts with a doctor examining a pregnant woman and hearing what he thought was a heart murmur in the fetus. The pages build upon each other, asking students to…
