There are two kinds of attractive forces shown in this model: Coulomb forces (the attraction between ions) and Van der Waals forces (an additional attractive force between all atoms).

Online labs provide 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.
Please note that the Go-Lab Authoring Platform Graasp is no longer maintained. This means that it is not possible to create and publish new Go-Lab Inquiry Learning Spaces using the labs listed on this page. However, you can still access the labs and use them directly on the providers' websites with help of the preview links, which you will find on the dedicated lab pages. If you are interested in creating and using Inquiry Learning Spaces in your classroom, please visit the new Authoring Platform Graasp.org
If you are looking for online labs selected for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.

Investigate the relationship between the volume of a gas and the pressure it exerts on its container. This relationship is commonly known as Boyle's Law. The pressure of a gas tends to decrease as the volume of the gas increases.
Primary aims of the Lab:
This simulation allows students to perform a double displacement reaction using sodium sulphate and barium chloride solutions.
A model to help demonstrate the key factors affecting rates of reaction. Not suitable for generation of rates data but helps students visualise the processes.
Kinetic Molecular Theory describes the behaviour of tiny gas particles, which are too small to be seen even with the strongest microscope. Kinetic means "motion," so the theory is all about particles moving!
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.
This animation illustrates the absorption of infrared radiation by CO2 in the troposphere and the collisional loss of this absorbed energy to surrounding N2 and O2 molecules. In this animation the user can sweep through a region of the IR spectrum and excite some of the vibrational modes of CO2.
Our objective is to study the variation of cell potential of Zn│Zn2+ ││Cu2+│Cu cell with change in the concentration of electrolytes (CuSO4 and ZnSO4) at room temperature. Students understand the terms, electrochemical cell, electrolytic cell, Daniell cell, salt bridge, EMF.
This lab will help you learn how to build inorganic molecules. You will also be able to investigate the nature of the bonds between the atoms and how are electrons placed.
Explore the role of temperature in the rate of diffusion of a substance. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.
