An introduction to chemical reactions, looking at what chemical reactions are, how to identify reversible and irreversible reactions, and how to write simple worded reaction equations (reversible and irreversible!) I use this as an introduction to the ‘Chemical and Physical Reactions’ topic in year 7 science. Additional homework sheet spliced with another free resource on TES of identifying reversible and irreversible reactions.

A guided PowerPoint lesson and work-along worksheet duo on identifying and defining elements, compounds, and mixtures. The worksheet asks questions relating to the order of the PowerPoint, so makes it easy for students to work along with the PowerPoint and understand key points from the task.
