In the series on science experiments, this article explains Boyle’s law and the experiments that can be done in the classroom.

How do we measure elements? What is a mole and how is the Avagadro number related to this unit of measurement? Find out from the experiments given in this article.

One of the first lessons we are taught in chemistry is that all matter is made of atoms and molecules. And that these atoms and molecules are tiny particles? But do we know how tiny atoms and molecules are? There are experiments which can help us determine. This article mentions one such experiment.

This article explains how one can set up experiments either to prove or disprove a hypothesis.

Science teaching must emphasise both content and process, one without the other is meaningless. Content can be acquired from books and from experimentation. And experimentation is the process of science.

Metals play an important role in the lives of human beings. Whether it is iron, silver, gold or copper, man has been associated with metal since the historic ages. Let us understand these metals better through some experiments.

Observing the reactions of the halogens, especially chlorine is quite easy with Small Scale Chemistry. Here we give some experiments that you could try out.
