Science – Chemical Substances

Course Access: 300 days access
Course Overview
This chemistry lesson describes the different types of chemical substances. We first describe the three states of matter – solids, liquids and gases, and changes of state. We’ll look at the periodic table of elements, metals and non-metals, and explain the difference between a mixture and a compound and the different ways of separating mixtures in a lab. Finally, we cover acids, bases and the pH scale – and the two experiments associated with them.
