Exploring the Chemistry of Adrenaline
Explore the fascinating relationship between the structure and function of four important molecules: adrenaline, phenylephrine, pseudoephedrine, and methamphetamine. These compounds share a common framework but differ in their functional groups, which affects how they work in the body. By coloring the diagrams, students identify key features, such as hydroxyl and methyl groups. Small changes can…

Cell Signaling – Comprehensive Unit Plan
Cell signaling is the process by which cells communicate with each other and respond to external stimuli, ensuring the coordination of vital biological functions. This system involves a signal binding to a receptor on a target cell, and triggering a series of intracellular events. These signaling pathways often include second messengers, protein kinases, and phosphorylation…

Investigation: Apples and Pectinase Enzyme
In this experiment, high school students will investigate the role of enzymes by testing the effects of pectinase on apples. The objective is to compare the amount of juice extracted from apples treated with pectinase to those left untreated. In addition, students change the temperature of the solutions to compare enzyme activity at cold and…
