Every 40 seconds, someone in the United States has a heart attack (Heart Disease and Stroke Statistics 2017). Students may experience or be affected by several incidences of heart attacks throughout their life. As such, students should be aware of the risk factors and learn the underlying reasons for a heart attack. Most students believe they are…

Evolution can be a difficult concept for students, even though it is an organizing principle in biology. It can also be a challenge for teachers to cover evolution properly (or at all) in the classroom, whether due to personal attitudes or lack of knowledge or confidence in the material (Rutledge and Mitchell 2002). Even in some states where…

This article describes a lesson in which high school biology, ecology, environmental science, anatomy, and physiology students can devise hypotheses and test them with scientific data, identify unanswered questions, and design an additional study to answer those questions. This module connects students with exciting research and current science…

Many traditional science curricula explore human body systems separately, paying little attention to how the systems interact. For example, the textbooks "Biology" (Miller and Levine 2006) and "Biology: An Everyday Experience" (Kaskel, Hummer, and Daniel 2003) detail the structure and function of each system and individual organs but offer little…

The study of the human form is fundamental to both science and art curricula. For vertebrates, perhaps no feature is more important than the skeleton to determine observable form and function. As Leonard da Vinci's famous Proportions of the Human Figure (Virtruvian Man) illustrates, the size, shape, and proportions of the human body are defined by…

Despite student interest, the heart is often a poorly understood topic in biology. To help students understand this vital organ's physiology, the author created this investigation activity involving the mammalian heart and its role in the circulatory system. Students design, build, and demonstrate working artificial "hearts" to exhibit what they…

Teaching the anatomy of the muscle system to high school students can be challenging. Students often learn about muscle anatomy by memorizing information from textbooks or by observing plastic, inflexible models. Although these mediums help students learn about muscle placement, the mediums do not facilitate understanding regarding integration of…

The author examines the evolutionary and neural roots of a triune intelligence comprised of a primal mind, an emotional mind, and a rational mind. A simple brain model and some definitions of unfamiliar behavioral terms are included. (Author/MA)

Promotes a reductionist approach to teaching about the endocrine system in high school biology and anatomy courses. Encourages the study of how hormones travel to the cells and affect them. Provides suggestions for activities and discussion questions, along with sample diagrams and flow charts. (TW)

Provides suggestions for a unit on the biological process of aging. Includes three activity sheets on the comparison of jaws and dentition from differently aged people, a denture survey, and eating and living without teeth. Includes a framework for organizing a course on the physiology of aging. (RT)

In this article, the author presents a two-week evolution unit for his biology class. He uses Maria Sybilla Merian (1647-1717) as an example of an Enlightenment mind at work--in this case a woman recognized as one of the great artists and natural scientists of her time. Her representations of butterflies, caterpillars and their pupae, and the…

Studying "Caenorhabditis elegans" ("C. elegans") live cultures provides excellent opportunities for authentic inquiry in a high school anatomy and physiology or other biology lab course. Using a digital dissection microscope, a student can photograph the organism during various stages of development and study and analyze the images. In this…

Describes procedures for examining a beetle's anatomy with microsurgical tools. Instructions for experimental exercises dealing with the insect's structure and digestive enzymes are outlined. Tips on how to make a microscalpel are also included. (TW)

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

Described is a curriculum for a pathology class offered to eleventh and twelfth graders. Included are suggestions for laboratory activities and student projects. These activities can be incorporated into other science classes. (KR)
