Models

by Grades

Elementary (K-5)

Pumpkin Contest

A simulation on artificial selection. Enjoy growing giant or tiny pumpkins!

Goldfish Breeding

A simulation of artificial selection. Enjoy breeding beautiful goldfish! Suggested for elementary students.

Secondary (6-8 & 9-12)

Bark Beetle Epidemic

Explore forest dynamics resulting from the interaction among bark beetle, spruce forest, temperature, drought severity, and tree diversity.

Carrying Capacity

Explore carrying capacity in a hypothetic elk population. You may explore how carrying capacity is influenced by four types of factors: food, predator, another herbivore, and temperature.

Brine Shrimps in Great Salt Lake

Explore the bird and brine shrimp population dynamics in south arm of the Great Salt Lake resulting from the lake salinity, affected by stream inflow, north arm water inflow, and evaporation.

Mendelian Inheritance in Sunflowers

Investigate monohybrid, dihybrid and trihybrid cross in sunflowers.


Multiallelic and Codominant Inheritance

Investigate the polymorphism resulted from multiple allelism and various dominance mechanisms.

Genetic Linkage

Investigate the genetic linkage, including both X-linkage and autosomal linkage.

Rock Pocket Mice-Factors

Examine the roles of mutation, heritability, and selection in the process of rock pocket mouse evolution.

Galapagos Finches

Investigate the effect of different food resources on finch beak depth in this model.

Stickleback Evolution

This model simulates the contemporary evolution of threespine stickleback in Loberg Lake, Alaska.

College

Genetic Code

Synthesize an mRNA, translate it, and CRACK genetic code!

Genetic Drift & Natural Selection

Investigate the changes in allele and genotype frequencies affected only by genetic drift and by both genetic drift and natural selection.

Coevolution

This is a simulation modeling the process of coevolution. Users may also observe different evolutionary patterns by adjusting the speed mutation extent in prey and/or predator populations.

Evolution of Antibiotic Resistance

This model reveals the same scenario in the giant petri dish experiment on the evolution of antibiotic resistance. Mutation and reproduction rates are included to expand student's exploration to the process.

Stickleback Evolution--Eda gene

This model simulates the contemporary evolution of threespine stickleback in Loberg Lake, Alaska. Users can examine the changes in allele frequencies over time.

Rock Pocket Mice-Fitness

Examine the roles of mutation, heritability, and selection in the process of rock pocket mouse evolution. Allow users to track offspring fitness.

Selection in Guppies

Investigate guppy coloration patterns in various habitats and infer the underlying selection mechanisms.

Speciation

Investigate the effects of different factors on the evolution of coloration in a simulated fish population, especially the divergence in allopatry and sympatry.

Hardy-Weinberg Equilibrium

Explore various conditions in which HW is violated and learn how the allelic and genotypic frequencies change under these conditions.

Cattle Body Size Evolution

Investigate the evolution of cattle body size affected by different selection mechanisms.

Human Skin Color Evolution

How does UV affect human skin color evolution through the effect of folic acid and vitamin D on human reproduction and survival? Test your ideas in this model.
