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.

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.

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
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.
The Radioactivity Lab examines the intensity of radiation over distance, demonstrating the effects of the inverse square law.
Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.Primary aims of the lab:
You will see that there is a difference between reality and theory.
The light energy reaches the solar cell and is converted into electricity by the photovoltaic effect.The solar cell converts light energy into electricity. The amount of energy is directly related to the intensity of light that strikes the cell.
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.
Many organic molecules exhibit characteristic vibrational modes that produce spectral features in the infrared region. These provide the experimental basis for identifying functional groups.
This virtual lab serves as a bridge from classical mechanics to the inherently probabilistic nature of quantum theory. It allows students to analyze a classical system, here a block oscillating on a spring, in a probabilistic way.
