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…

Investigation: Two Point Discrimination Test
Students investigate the sensitivity of different areas of the skin using a mathematical compass to stimulate mechanoreceptors. The procedure asks students to place the points of the compass on different areas, such as the forearm and the palm and have a test subject report whether one point is being felt or two points. The compass…

Investigation: Taste Buds and Signal Transduction
As a part of the chapter on cell signal pathways, students perform a lab that examines how their taste buds are affected by Gymnema. For this lab, I simply placed a question on the board “How does Gymnema tea affect your ability to taste sweet foods?” I provided them with a list of…

Investigation: Enzyme and Substrate Concentrations
Students who complete the Enzyme Investigation lab can further explore enzymes with this lab on how concentrations of the substrate (hydrogen peroxide) and the enzyme ( catalase) can affect the rate of reaction. In the first experiment, students simply made a judgement about the amount of bubbling to indicate reaction speed, though this is a…

Cell Membrane and Transport
This reinforcement worksheet displays a graphic of the cell membrane showing the phospholipid bilayer and embedded proteins. Students identify structures within the bilayer and use reasoning to determine how molecules are moving across the membrane in response to a hypertonic solution. Worksheet was designed for freshman level biology classes who are studying osmosis and…

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”…
