In this lesson, we will learn about the difference between physical changes and chemical reactions. We will learn about the particles in both of these types of change and the signs to look out for in a chemical reaction. You will need a pencil, a ruler and a piece of paper for this lesson. If you have baking soda and vinegar then you will need that for an investigation too, but don't worry you can still take part without these things.
Watch the following video, complete the activities as you go along and complete the quiz.
