Global heating - KS3 Chemistry lesson

A full 1 hour lesson designed for a mixed ability year 8 class.
This is the 7th lesson in “Chapter 4 - The Earth" from Activate 2, Chemistry. This lesson is on 'global heating. This lesson has been separated from igneous rocks, which is found on the same textbook pages.
This lesson should be suitable to teach to any KS3 Chemistry class, even by those where Chemistry is not their specialism.
This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks.

From this lesson, students should be able to:

• Define the term ‘greenhouse effect’
• Recall two greenhouse gases (carbon dioxide, methane)
• Describe the greenhouse effect
• Define the term ‘global heating’ or ‘global warming’
• Use data from a graph to describe how carbon dioxide levels have changed in the atmosphere in recent years
• Use a graph to describe the relationship between carbon dioxide levels in the atmosphere and the average global surface temperatures

All of my lessons contain:

• A 5-in-5 retrieval-style starter
• An interesting lesson hook, careers link, or retrieval practice to start the lesson
• Teacher input slides with dual coding and reduced cognitive load, where key vocabulary is explicitly taught
• Teacher models
• Regular ‘check for understanding’ slides, such as hand signals quizzes and whiteboard quizzes
• Regular student independent practice slides, with optional scaffolds, challenges and answer slides
• A plenary task
