This resource contains little 5 minute activities for students to do as part of their Chemistry revision. It has been made using the Edexcel iGCSE Chemistry specification and all activities are chunked into the main topic areas: Principals of Chemistry, Inorganic Chemistry, Physical Chemistry and Organic Chemistry. A suggested way to use the resource is to ask students to complete the activity and then colour code the task red, amber, green based on their confidence. This will help them to sort out which areas of the course they need to focus on the most. Another way to use the resource is using the Brain, Book, Buddy, Boss strategy.
