Case Study: How to Survive a Cholera Epidemic
In this case, students explore how cholera is spread and how it affects the body. The case is divided into four sections, with the first part focusing on the role of clean water supplies and the spread of bacteria. In the second part, the affects of the bacteria are examined, with attention on how the…

Case Study – The Tired Swimmer
This case study was modified from the National Center for Case Study Teaching in Science so that it is more appropriate for basic high school students in anatomy and physiology. This case is intended to be used during the chapter on muscles as it requires students to examine how the neurotransmitter, acetylcholine is used…

Macromolecules: Sketchnotes
In the past, I’ve had students create concept maps to help them organize the four macromolecules and related details. This year, I modified the assignment to try to encourage the use of sketching to help students remember the details. Students were asked to focus on one of the four macromolecules: lipids, carbohydrates, nucleic acids, or…

Case Study: Can a Virus Cause Diabetes?
This case asks students to examine data on children diagnosed with Type 1 Diabetes after reading a short story about a young girl who was losing weight and feeling thirsty. The content looks at a possible connection between diabetes and infection by the coxsackie virus, a virus that is responsible for “hand, foot, and mouth”…

Flashcard Creators and Templates
If you teach a class that requires students to memorize information, then you have probably worked with students on developing strategies for memorization. I often tell my anatomy students that they might forget some of the details of what they have learned, but study strategies will stay with them through college. I could get…

Bone Matrix Anatomy (Coloring)
Anatomy students learn about the skeletal system, where they examine bones and how the bones fit together to make up an entire skeleton. In addition, some course also explore bone tissue and how bone is formed, repaired, and even broken down to release minerals. The bone matrix is composed of cells called osteocytes…

Case Study: How Did the Guppy Get His Color?
This case study examines evolution in guppies as evidenced by color variation in populations. It is based on an iconic study performed by John Endler where he collected data on guppies by scoring the size, number, and brightness of spots. Students progress though the slides (lecture and discussion), and examine details of Endler’s study, such as where…

Case Study: How Do Genes Determine Skin Color?
This case study focuses on a news story whose headline declares that a “mother is a the only black woman to give birth to two white babies.” Students look past the sensationalized headline to discover how skin color is controlled by multiple genes and make a final judgement about whether statements made in the…

Case Study: Why Are There No Male Calico Cats?
This presentation case study asks two important questions regarding cat coloration: The case is presented as a slide presentation where students consider evidence and data related to cat coloration and chromosomes. Working in small groups, they discuss the case and eventually answer the two main questions. I usually collect their answers at the end of class…

Case Study – What’s Wrong with Timothy?
The endocrine system can be a difficult subject to cover in anatomy. It isn’t as showy as the other systems where you can label organs or dissect an eyeball. Students must also memorize a number of hormones and their functions which have complicated names like thyroxine and tri-iodothyronine. When I first started teaching anatomy,…

HHMI and Case Studies
HHMI Biointeractive has many interactive resources, case studies, and data analysis. Here is a list of my favorites: Interactive Case Study For Studying Elephant Communication Effects of Fungicides on Bumble Bee Colonies Human Skin Color: Evidence for Selection Lactase Persistence: Evidence for Selection Exploring Trophic Cascades Exploring Biomes in Gorongosa Nutrient Cycling in the Serengeti

Case Study: John Snow and the Origin of Epidemiology
This case study explores a time before the Germ Theory when doctors were uncertain how disease was spread. Current models, such as the humoral or miasma model could not fully explain how cholera infected some households, but not others. This case story explores London, England in 1854 after an outbreak of cholera which had…

Case Study – Are Nanobacteria Alive?
In this case study, students review the evidence of scientists on both sides of the controversy questioning whether nanobacteria are living organisms.
