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.
Microcosm (Quantum)
Sort by
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH.
Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.
Learning goals
Bond (from bonding in chemistry) helps students learn about solubility and precipitation of salts. Bond contains a database with thousands of salts and the most common ions, with information about solubility and colours. The setup is similar to what students would do in a real chemistry lab.
13C NMR spectroscopy is a powerful tool to help determine the structure of molecules in organic chemistry, by mapping the framework of C atoms in a molecule.
This applet simulates von Lenard's and Millikan's experiments which provided the experimental understanding of the photoelectric effect and eventual acceptance (albeit reluctant) of Einstein's quantum hypothesis.
You can observe the light emitted by excited gas atoms of particular elements in this lab. In some sense, these are atomic fingerprints. Note that the lines are shown are the brightest lines in a spectrum - you may be able to see additional lines if you look at the spectrum from a real gas tube.
The aim of this experiment, which is important as an introduction to quantum physics, is to understand the wave properties of the electron postulated by de Broglie as well as to model solid-state crystal structures microscopically.
This lab presents the spectrum of eletormagnetic radiation in terms of wavelength and frequency.
This app shows the interference of two circular respectively spherical waves (e.g. of water or sound waves). The waves spread out from two sources oscillating with the same phase.
