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Please note that the Go-Lab Authoring Platform Graasp is no longer maintained.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

Waves 
Structure Of Matter

This is a simulation of the Doppler effect. You can set both the initial position and the velocity of the source (the small blue dot).
This lab is designed to help students visualize distance between two synchronized sources that will lead to constructive and destructive interference.
This lab is designed to have students investigate the relationship between the speed of a wave, the frequency of the wave and the wavelength of the wave. Students can vary wave speed and frequency. Each of these should be varied while leaving the other variable constant.
This lab is designed to help students visualize the formation of standing waves in a wind instrument. Students will be able to view fundamental waves as well as some higher harmonics. They can work with a tube with two open ends or just one open end.
This HTML5 app demonstrates the harmonics of the air in a tube as an example of standing longitudinal waves. It illustrates the movement of the molecules in the air during such an oscillation.
In this lab, you can explore what light does when it encounters a diffraction grating. Use at least one of the checkboxes to turn on a beam of light.
In this lab, you can explore the diffraction of waves by a single slit. The width of the opening is controlled by the slider. Initially, the waves are shown in black and white (grayscale), with both the peaks and troughs being white. Black indicates a zero amplitude.
This is a simulation of a longitudinal wave on a Slinky, shown in middle. At the top is a reference Slinky, showing what the Slinky looks like when there is no wave passing through it.
