What Determines Gender in Humans? part of Interactive Lectures:Examples
In this activity students examine karyotypes from five individuals to try to identify which chromosomes determine gender in humans. This activity is also a good illustration of meiotic non-disjunction. -
Simple Mendelian Genetics: An interactive lecture using "DNA from the Beginning" part of Interactive Lectures:Examples
An interactive lecture that uses flash animations showing the researcher and their experiments that were used to develop the basic concepts in Mendelian genetics. Includes multiple choice questions students can ...
Searching Genbank part of Teaching with Data:Examples
An active problem-based assignment that uses the Genbank database to teach the basics of molecular biology and molecular evolution
Plant Pest Control part of Teaching with Data:Examples
This learning experience introduces participants to scientific inquiry, hypothesis formation, experimental design, data analysis, and interpretation.
Genetic Drift part of Mathematics and Statistics Models:Examples
In this biology simulation, students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. Students run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results.
Human Demographics part of Mathematics and Statistics Models:Examples
In this biology simulation students explore factors that change human population growth including age at which women begin to bear children, fertility rate and death rate.
Constructing Phylogenetic Trees: The Whippo Story part of Interactive Lectures:Examples
An interactive lecture in which students use data on feeding habits and habitat, skeletons, and DNA sequences to draw phylogenetic trees. -
Light Reactions of Photosynthesis part of Teaching with Visualizations:Examples
Light reactions of photosynthesis including location and steps for non-cyclic and cyclic photophosphorylation.
Dark Reactions of Photosynthesis part of Teaching with Visualizations:Examples
The dark reactions of photosynthesis (Calvin Cycle) are presented in this learning experience to show where these processes take place in the plant as well as the specific reactions involved.
Plant Growth Regulation part of Teaching with Visualizations:Examples
Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are investigated in this learning activity to demonstrate how these chemicals (hormones) affect plant growth and development.
