Physical and chemical changes

In this lesson, we find out what happens to the arrangement and behaviour of particles during a change of state. Learn about the properties of solids, liquids and gases and how to identify changes of state.

In this lesson, we find out what happens during a physical change, look at examples of physical changes and complete our own investigation into the physical change that occurs when chocolate melts.

In this lesson, we will find out what happens during a chemical change, look at some examples of chemical changes and practise representing chemical changes using word equations.

In this lesson, we will compare the characteristics of chemical and physical changes and use our knowledge to categorise changes as either physical changes or chemical reactions.

In this lesson, we will learn about reactivity and how scientists investigate how reactive a substance is. We will conduct our own investigation into the reactivity of vinegar while looking at the variables we need to change, control and measure in our investigation.

In this lesson, we will learn about what makes our results repeatable and reproducible. We will complete an investigation into the reactivity of metals and analyse our results to see if they are repeatable and reproducible.
