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.
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.
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!
Bond (from bonding in chemistry) helps students learn about solubility and precipitation of salts. Bond contains a database with thousands of salts and the most common ions, with information about solubility and colours. The setup is similar to what students would do in a real chemistry lab.
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:
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales.
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.
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.
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.
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.
