  • Mixtures

    Compounds are made up of more than one kind of atom, but they always occur in fixed ratios in a chemical compound. In this lesson we are getting into the chemistry kitchen and putting pure substances together to make mixtures.

  • Particle model of matter

    Atoms can chemically combine to form molecules. These molecules are also particles and cannot be separated into their atoms by physical means. In this lesson we study the way in which these particles react by using the particle model of matter.

  • States of matter

    Using the model of matter we are going to describe the three classic states of matter that we find namely solids, liquids and gases and their behaviours when their states change.
