Explore the role of pore size in the diffusion of a substance across a membrane. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.

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 the Electrical Circuit Lab students can create their own electrical circuits and do measurements on it. In the circuits the students can use resistors, light bulbs, switches, capacitors and coils. The circuits can be powered by a AC/DC power supply or batteries.
This simulation visualizes different eye effects, such as astigmatism, hyperopia and myopia, and how they can be fixed with different types of glass lenses.
Study of the heat propagation means by convection and radiation. When the lamp is switched on, it transfers heat to the surrounding environment primarily through thermal radiation. Then, the flow of air forced by external processes diffuses heat by natural convection.
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!
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.
In this lab, you can explore the diffraction of waves through a single slit and double-slit interference pattern.
Explore the role of permeable membrane in diffusion. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.
With this lab you will find out how separation of mixtures is done using the following techniques:
Separating funnel
Chromatography
Centrifugation
Simple distillation
Fractional distillation
In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create the final solution.
