Evolution
- Stem Case
Working as a CDC researcher, students investigate an outbreak of multi-drug resistant bacterial infections and determine how evolution was involved by tracing the source and cause of the...
Lesson InfoEvolution: Natural and Artificial Selection
5 Minute Preview
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Compare the processes of natural and artificial selection....
Lesson Info Launch GizmoEvolution: Mutation and Selection
5 Minute Preview
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Inheritance of color occurs according to Mendel's laws and...
Lesson Info Launch GizmoHuman Evolution - Skull Analysis
5 Minute Preview
Compare the skulls of a variety of significant human ancestors, or hominids. Use available tools to measure lengths, areas, and angles of important features. Each skull can be viewed from...
Lesson Info Launch GizmoRainfall and Bird Beaks
5 Minute Preview
Study the thickness of birds' beaks over a five-year period as you control the yearly rainfall on an isolated island. As the environmental conditions change, the species must adapt (a...
Lesson Info Launch GizmoH-R Diagram
5 Minute Preview
A collection of stars visible from Earth can be arranged and classified based on their color, temperature, luminosity, radius, and mass. This can be done using one or two-dimensional...
Lesson Info Launch GizmoNatural Selection
5 Minute Preview
You are a bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the...
Lesson Info Launch GizmoHardy-Weinberg Equilibrium
5 Minute Preview
Set the initial percentages of three types of parrots in a population and track changes in genotype and allele frequency through several generations. Analyze population data to develop an...

Lesson InfoEvolution: Natural and Artificial Selection
5 Minute Preview
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Compare the processes of natural and artificial selection. Manipulate the mutation rate, and determine how mutation rate affects adaptation and evolution.
Lesson Info Launch GizmoEvolution: Mutation and Selection
5 Minute Preview
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Inheritance of color occurs according to Mendel's laws and probability. Mutations occur at random, and probability of capture by predators is determined by the insect's camouflage.
Lesson Info Launch GizmoHuman Evolution - Skull Analysis
5 Minute Preview
Compare the skulls of a variety of significant human ancestors, or hominids. Use available tools to measure lengths, areas, and angles of important features. Each skull can be viewed from the front, side, or from below. Additional information regarding the age, location, and discoverer of each skull can be displayed.
Lesson Info Launch GizmoRainfall and Bird Beaks
5 Minute Preview
Study the thickness of birds' beaks over a five-year period as you control the yearly rainfall on an isolated island. As the environmental conditions change, the species must adapt (a real-world consequence) to avoid extinction.
Lesson Info Launch GizmoH-R Diagram
5 Minute Preview
A collection of stars visible from Earth can be arranged and classified based on their color, temperature, luminosity, radius, and mass. This can be done using one or two-dimensional plots, including a Hertzsprung-Russell diagram of luminosity vs. temperature.
Lesson Info Launch GizmoNatural Selection
5 Minute Preview
You are a bird hunting moths (both dark and light) that live on trees. As you capture the moths most easily visible against the tree surface, the moth populations change, illustrating the effects of natural selection.
Lesson Info Launch GizmoHardy-Weinberg Equilibrium
5 Minute Preview
Set the initial percentages of three types of parrots in a population and track changes in genotype and allele frequency through several generations. Analyze population data to develop an understanding of the Hardy-Weinberg equilibrium. Determine how initial allele percentages will affect the equilibrium state of the population.

Lesson Info Launch GizmoCladograms
- New!
5 Minute Preview
Based on the similarities and differences between different organisms, create branching diagrams called cladograms to show how they are related. Use both morphological data (physical traits) and molecular data to create the simplest and most likely cladograms. Five different sets of organisms are available.
