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.

Waves

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.
In this lab, you can explore the concept of the Doppler shift for electromagnetic waves. At the top is a simplified version of the emission spectrum from the Sun.
In this lab, you can explore waves and their interference phenomenon. You can observe both constructive and destructive interference. The first two plots show the individual waves from different directions and the third shows the sum of these two waves.
In Newton's rings, a curved watch glass sits on top of a flat piece of glass. A thin film of air is in between the two - the thin film has a thickness that is zero where the two pieces of glass touch, and gradually increases as you move away from that point.
The lab above simulates what would happen if a spinning fidget spinner was placed in a photocopier. Try hitting the Pause button - that freezes the fidget spinner at one instant, so you capture a snapshot of the fidget spinner at one time.
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).
A spring wave has the same spirit as the pendulum wave. In this simulation, each ball oscillates back and forth on its own spring (the springs are not shown), experiencing simple harmonic motion.
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.
This lab demonstrates the interference of waves from two identical sources that are separated by a variable distance. The wave crests are shown in red and the troughs in blue, with black indicating a local wave amplitude of zero.
