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.
If you select labs in Norwegian Bokmål, the descriptions on this website will still be displayed in English. However, when you include the lab in an ILS and change the language setting of the ILS to Norwegian Bokmål, the lab will be displayed in Norwegian Bokmål within the ILS.

There are two similar labs that you can see if you create a space, feel free to choose which one to use. Please note that while the preview shows you only one, the screenshots present both labs.
Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.
Learn about conservation of energy with a skater dude! Explore different tracks and view the kinetic energy, potential energy and friction as he moves. Build your own tracks, ramps and jumps for the skater.
Aims of the lab:
Stretch and compress springs to explore the relationships between force, spring constant, displacement, and potential energy! Investigate what happens when two springs are connected in series and parallel.
Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Explore pressure at the atomic level. All matter is made up of atoms, which make up molecules. These atoms and molecules are always in motion. When atoms and molecules are contained, we can measure the amount of pressure they exert on the container.
See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. The sizes of the symbols in the equation change to match the circuit diagram.
Sample Learning Goals
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:
Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.
