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.

Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.
Learning goals
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.
Atomic orbitals are mathematical functions that describe the properties of electrons in atoms.Using this lab, you will learn how to build atomic orbitals according to the general principals involved and you will also be able to visualize their shapes.
An interactive whiteboard activity where students build an atom by dragging electrons, neutrons and protons onto the template. The element information box shows if they are correct. The animation can also be used to show how ions form.
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!

Methyl orange is an orange, azoic dye and is used as pH-indicator, with a transition range from 3.1 to 4.4, as well as for dyeing and printing textiles. In this remote lab students can examine the synthesis of methyl orange.
