Explore what happens at the molecular level during a phase change. The three common physical states of matter (also called phases) are solid, liquid and gas. Matter can change phase with the addition or subtraction of heat. Molecules are always in 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.

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants.
The primary aims of the lab are:
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!
Diffusion describes how particles of matter move through other liquids and gases (including air). Diffusion explains how the mass of particles and temperature are related to how quickly particles spread out over an area.
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
Primary aims of the lab:
This applet is used to explore the relationship between the isotopic ratios of an element and the element's atomic weight. Select any atomic element and manipulate its isotope ratios using the provided pie chart or table.
Convert between pH values and concentration of hydronium ions. An interactive graph visualizes the formulaic relationship.
In this lab, our objective is to study the shift of equilibrium between ferric ions and thiocyanate ions by increasing the concentration of either of them.
This simulation demonstrates the relationship between the number of molucules of a gas and the volume they occupy.
How does solar radiation interact with the Earth and its atmosphere to cause global warming? Use this lab to see what’s going on at the molecular level.
