Go to A Methanol-Free Method of Extracting Secondary Chemicals
A Methanol-Free Method of Extracting Secondary Chemicals
This experiment examined the inducible responses of tobacco. Leaf toxicity was assessed by a brine shrimp bioassay. A new method of extraction was used in this bioassay. Previously, secondary chemical...

Go to A Three-Part Laboratory Exercise Using Flightless Fruit Flies (<i>Drosophila melanogaster</i>) to Study Modes of Inheritance
A Three-Part Laboratory Exercise Using Flightless Fruit Flies (Drosophila melanogaster) to Study Modes of Inheritance
This is an inquiry-based investigation of genetic modes of inheritance using flightless Drosophila as the experimental organism. We present the three-part laboratory writeup, suitable for use a...

Go to An Inquiry-Based Enzyme Lab
An Inquiry-Based Enzyme Lab
A laboratory commonly used in introductory biology classes is the breakdown of starch by the enzyme amylase. These labs tend use a “cookbook” format in which students are given explicit, step-by-step ...

Go to Building Retentive Understanding of Biology By Using a
Building Retentive Understanding of Biology By Using a "Hybrid" Format With an Interactive Website and Active-Learning Exercises
Introductory Biology at North Carolina State University is a freshman course taught in large lecture halls using a standard, lecture-based format. We are experimenting with a hybrid course that utiliz...

Go to Conversion Immersion, Version 2.0: Working Together to Create Investigative Labs
Conversion Immersion, Version 2.0: Working Together to Create Investigative Labs
This workshop built on the success of the first “Conversion Immersion” in 2004. The objective was to provide a forum for instructors to convert traditional “cookbook” laboratories to a more investigat...

Go to Defining the Patuxent River Watershed
Defining the Patuxent River Watershed
The lab is designed to be engaging, using a place students know to introduce them to a concept, and then letting them take the concept and apply it to the watershed I want them to discover. We define ...

Go to Demonstrating the Concepts of Mutagenesis and Genetic Screening Using the Fungal System <i>Coprinus cinereus</i>
Demonstrating the Concepts of Mutagenesis and Genetic Screening Using the Fungal System Coprinus cinereus
Coprinus cinereus, basidiomycete fungus, is an excellent model system to use for the studies of meiosis because the process is naturally synchronous. C. cinereus can grow as a monokaryon...

Go to Determining Human Blood Type by Non-Invasive Methods
Determining Human Blood Type by Non-Invasive Methods
When teaching co-dominance in my genetics course, I discovered only 1 in 3 students knew their ABO blood type. This lab exercise allows students to determine their ABO blood type without drawing blood...

Go to Extraction, Sequencing, and Analysis of Mitochondrial DNA
Extraction, Sequencing, and Analysis of Mitochondrial DNA
In this laboratory, students extract mitochondrial DNA (mtDNA) from eyelash hair follicles. The instructor then uses polymerase chain reaction to amplify a 440 bp segment of the control region. After ...
