This model simulates the classic example of natural selection on color patterns in peppered moths (Biston betularia). When air pollution is low, lichens cover the trees and the light moths are well camouflaged. When air pollution is high, the trees become dark and the light moths stand out.

Online labs provide your students with the possibility to conduct scientific experiments in an online environment. Remotely-operated labs (remote labs) offer an opportunity to experiment with real equipment from remote locations. Virtual labs simulate the scientific equipment. Data sets present data from already performed lab experiments. Please use the filters on the right to find appropriate online labs for your class. Labs can be combined with dedicated Apps to create Inquiry Learning Spaces (ILSs).
If you are looking for online labs especially suitable for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.

This model is an adaptation of the classic experiment conducted by Peter Buri (1956), which documented genetic drift in laboratory populations of Drosophila.
This is an updated version of an existing lab. It includes some theoretical background information and the lab which simulates MacArthur & Wilson's 1963 Island Biogeography Equilibrium paper.
This simple model simulates seining a stream for animal life. Sixteen species of;invertebrates wash down the stream. When the seine is open they may get caught and separated into buckets.
This lab is an abridged Html5 version of the Java applet lab Sexual Selection in Guppies. It has been optimized to work with tablet computers.
This model simulates Endler's 1980 classic experiment on the balance of sexual selection and natural selection. In guppies, females prefer to mate with males that have lots of spots, but those males are more easily seen by predators.
This model simulates MacArthur & Wilson's 1963 Island Biogeography Equilibrium paper. You can run virtual experiments manipulating the following: island size, distance from mainland, habitat type, and species types (e.g. birds, arthropods, etc.).
This is an updated version of the existing lab. It includes some theoretical background and the online lab, which allows students to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).
