Online labs provide 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.
Please note that the Go-Lab Authoring Platform Graasp is no longer maintained. This means that it is not possible to create and publish new Go-Lab Inquiry Learning Spaces using the labs listed on this page. However, you can still access the labs and use them directly on the providers' websites with help of the preview links, which you will find on the dedicated lab pages. If you are interested in creating and using Inquiry Learning Spaces in your classroom, please visit the new Authoring Platform Graasp.org
If you are looking for online labs selected for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.
If you select labs in English, the descriptions on this website will still be displayed in English. However, when you include the lab in an ILS and change the language setting of the ILS to English, the lab will be displayed in English within the ILS.

Investigate the relationship between the volume of a gas and the pressure it exerts on its container. This relationship is commonly known as Boyle's Law. The pressure of a gas tends to decrease as the volume of the gas increases.
Primary aims of the Lab:
This applet is used to explore the relationship between the isotopic ratios of an element and the element's atomic weight. Select any atomic element and manipulate its isotope ratios using the provided pie chart or table.
This simulation demonstrates the relationship between the number of molucules of a gas and the volume they occupy.
Explore different types of attractions between molecules. While all molecules are attracted to each other, some attractions are stronger than others.
Explore the role of polarity in the strength of intermolecular attractions. While all molecules are attracted to each other, some attractions are stronger than others.
Explore the structure of a liquid at the molecular level. Molecules are always in motion. Molecules in a liquid move moderately. All molecules are attracted to each other. Molecules can be weakly or strongly attracted to each other.
Explore the role of a molecule's mass with respect to its diffusion rate. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.
Investigate the difference in attractive force between polar and non-polar molecules by “pulling” apart pairs of molecules. While all molecules are attracted to each other, some attractions are stronger than others.
While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction.
