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.

In this lab, pupils can simulate the impact of an object (e.g., an asteroid) on the Earth, Moon or Mars. They can vary parameters such as the diameter, density and velocity of the projectile and see the characteristics of the resulting crater.

Students are asked to make predictions on how galaxies form and evolve in the Universe. They will use the ‘Galaxy Crash’ tool to simulate the evolution of 2 disc galaxies over time, and see if the results match their predictions.

From the theory is known that the energy which is radiated outward radically in three-dimensional space from a source is inversely proportional with the square of the distance from the source. This process is known as the Inverse square law.

The NAAP Lunar Phases Lab demonstrates how the earth-sun-moon geometry gives rise to the phases of the moon as seen from earth. A distant view of an observer looking down on earth as well as a perspective of an observer looking into the sky are used in the the simulator.

In 1671 the french astronomer Richer travelled from Paris (latitude φ = 48.8°) to Cayenne (latitude φ = 4.9°) in French-Guyana. In Cayenne he observed that his pendulum clock, which he carried with him, showed a delay of about 2 min/day.

A geodesic is a line representing the shortest route between two points. In simple terms, it might help to think of this as the route a crow (or aeroplane) would fly to get from one point to to another (ignoring any effects for wind).

A simple simulator for visualizing the expansion of the universe. Users can see vectors describing the velocities of galaxies and note that all galaxies are moving away from us. They can then change their perspective to another galaxy and note that Hubble's Law is seen from there as well.

Scale Height Lab is a parameter used to describe how something fades away with increasing distance – it is the distance over which a quantity decreases by a factor of 1/e. It is exclusively applied to planetary atmospheres in this lab, but is certainly used in many other contexts.

What is the form of a planetary orbit? The astronomers from Ptolemy to Copernicus had a clear (but wrong) answer to this question: A planet moves on a circle or at least on an orbit which can be explained by superposition of circular motions.
