This lesson is designed for the Activate KS3 Science Course, specifically Year 7 C3 ’Reactions’ module.

This lesson begins with an introduction to chemical reactions, students will read a paragraph of information on chemical reactions. Using the information students will answer a set of questions, this task can then be self-assessed using the mark scheme provided once complete.

Students will now watch a video about chemical reactions, they will need to write down as many things you might see/hear/feel during a chemical reaction. This work can the be self-assessed using the mark scheme provided on the PowerPoint presentation. Students will now summarise what they have learned so far by completing a ‘fill-in-the-blank’ task, this work can also be marked and corrected using the anwers provided

Students will now consider whether chemical reactions are useful or now, they will be given a list of different chemical reactions and they will need to sort these into two columns - useful or not useful. Students can then self-assess this task when it is complete.

Next, students will watch a video on the differences between chemical and physical changes. Whilst watching the video students will need to answer a set of questions, this work can self-assessed using the mark scheme provided.

The last task requires students to determine whether a set of examples are demonstrating a chemical or a physical change. They could complete this task as a class, using mini whiteboards.

The plenary task requires students to write three sentences to summarise what they have learned this lesson.
