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.

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.
This simulation shows the four inner planets of the solar system, as they orbit the Sun. Moving out from the Sun, we see Mercury, Venus, Earth, and Mars, in that order.
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.
This lab presents the spectrum of eletormagnetic radiation in terms of wavelength and frequency.
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.
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.
'Planets' is a web app created to help understanding the night sky. Unsurprisingly it's focused only on Solar System planets and our Moon.
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.
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.
