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.

Explore how the code embedded in DNA is translated into a protein. The process of converting the information in DNA into protein is a two-step process, involving transcription and translation. In transcription, an mRNA copy is made of the DNA.
Explore how changing the DNA sequence can change the amino acid sequence of a protein. Proteins are composed of long strings of amino acids. Proteins are coded for in the DNA. DNA is composed of four different types of nucleotides.
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 lab, through an experimental set-up, shows that carbon dioxide is released during aerobic respiration. This lab can also be used to study the effect of temperature on the rate of respiration.
This lab is used to study plant population density by the quadrat method.
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 simulations aims at demonstrating plasmolysis in peels of Rhoeo plant in hypotonic and hypertonic solutions using salt solution. Students can vary the concentration of NaCl and identify the type of solutions.
Students working at a distance in two different ILSs share a simulation of rabbit genetics. Changes made in one version of the simulation are simultaneously shown in the other version. However, in one version, there are black rabbits and in the other version white rabbits.
