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.

This simulation visualizes forces and work involved in moving a block along an inclined plane. Students can explore this phenomenon varying the ramp and the block characteristics.
There are two similar labs that you can see if you create a space, feel free to choose which one to use. Please note that while the preview shows you only one, the screenshots present both labs.
A drawing-based learning environment for the gears domain. The primary aims of the lab are: Let students to explore the ways in which gears and chains transmit motion.
In the Gravity Drop Lab students can investigate the influence of air and gravity on the time it takes for dropped objects to reach the ground. Several object can be dropped on the earth and the moon.
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:
In this lab, our objective is to study the shift of equilibrium between ferric ions and thiocyanate ions by increasing the concentration of either of them.
Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.Aims of the lab:
What keeps the Earth moving in its approximately circular path around the Sun? It's a combination of the 30 km/s speed of the Earth and the gravitational force exerted on the Earth by the Sun.
