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.

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.

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.
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.
Climate is regulated by the delicate balance of incoming and outgoing electromagnetic radiation. This applet first explores the climatic condition of various planets, focusing on Mars, Venus, and Earth.
Star in a Box is an interactive webapp which animates stars with different starting masses as they change during their lives. Some stars live fast-paced, dramatic lives, others change very little for billions of years.
The Faulkes Telescope Project provides access free-of-charge via the internet to robotic telescopes and a fully supported education programme to encourage teachers and students to engage in research-based science education.
'Planets' is a web app created to help understanding the night sky. Unsurprisingly it's focused only on Solar System planets and our Moon.
This is an open access archive of astronomical images. You can find astronomical images from public users of the LCOGT network.
A spaceship is flying a distance of 5 light hours, for example from Earth to the dwarf planet Pluto. The applet demonstrates that the clock in the spaceship goes more slowly than the two clocks of the system in which Earth and Pluto are motionless.
