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 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 model is an agent-based population genetics simulation. The program contains the tools to conduct virtual experiments violating all the assumptions of Hardy-Weinberg theory (small population, selection, mutation, migration, and non-random mating).
Knowing how many individuals are in a population can be critical. How can you tell how many there are when there are too many to count? This model simulates a pond of tadpoles. The population size can be estimated in three ways: direct sampling, sampling with removal, and mark/recapture.
Explore the role of pore size in the diffusion of a substance across a membrane. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.
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.
Explore how hydrophobic and hydrophilic interactions cause proteins to fold into specific shapes. Proteins, made up of amino acids, are used for many different purposes in the cell. The cell is an aqueous (water-filled) environment.
In 1962, Rachel Carson published 'Silent Spring', which drew attention to how the use of pesticides was indirectly decimating bird populations by causing thinning of egg-shells.
This lab can be used to grasp the concepts of power generation in an osmotic power plant. It is based on a simple model which incorporates geographical parameters. Students can choose a location for their osmotic power plant and compare it to the prototype in Norway.
