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.
