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Please note that the Go-Lab Authoring Platform Graasp is no longer maintained.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

This simulation allows students to visualize some characteristics of a working pulley such as applied force, work, pulled distance. Changing load, distance to lift and pulley diameter students can see how these variables influence the result.
This astronomy “Little Big Picture” was programmed by REU student Nick Robe. It is an early effort of the UNL Astronomy Education Group to provide materials for mobile devices. More astronomy teaching materials can be found on the web at astro.unl.edu.
In the Electrical Circuit Lab students can create their own electrical circuits and do measurements on it. In the circuits the students can use resistors, light bulbs, switches, capacitors and coils. The circuits can be powered by a AC/DC power supply or batteries.
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
Primary aims of the lab:
Hang masses from springs and adjust the spring constant and damping. Transport the lab to different planets, or slow down time. Observe the forces and energy in the system in real-time, and measure the period using the stopwatch.
Sample learning goals:
This lab demonstrates how a prism works. White light shines in from the left. You may be surprised to see that it goes straight into the prism, without splitting up inside the prism. Why is this? This is something of a special case.
This simulation shows the energy flow in a heat engine, such as a gasoline-powered car engine. For every 100 J (QH) of heat generated by burning fuel at a higher temperature, only a fraction can be used to do useful work (W).
13C NMR spectroscopy is a powerful tool to help determine the structure of molecules in organic chemistry, by mapping the framework of C atoms in a molecule.
This lab is designed to have students investigate the different changes that could be made to an air filled capacitor and the results that occur because of these changes. Students can vary the gap between the plates, the size of the plates, and the voltage across the plates.
