Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Increasing levels of greenhouse gases in the atmosphere is leading to global warming and climate change
  2. Carbon dioxide is a greenhouse gas, released by living organisms and produced when burning fuels
  3. Methane is a greenhouse gas, released by living organisms and from the ground
  4. Methane is a more potent greenhouse gas than carbon dioxide
  5. Reducing greenhouse gas emissions can reduce the rate of global warming and may even help to reverse it

Keywords

  • Greenhouse effect - the effect of some gases in the atmosphere that keep Earth’s surface warmer than it would be without them

  • Greenhouse gases - gases in the atmosphere that keep it warmer than it would be without them

  • Global warming - the increase in Earth’s average surface temperature

  • Carbon dioxide - a compound made of carbon and oxygen (CO₂) that is a gas at room temperature

  • Methane - a compound made of carbon and hydrogen (CH₄) that is a gas at room temperature

Common misconception

The greenhouse effect is the same as global warming.

Discuss the natural greenhouse effect and how it enables life on Earth to flourish. Emphasise that global warming refers to an increasing temperature, rather than to a temperature that is warmer.

When levels of greenhouse gases in the atmosphere increase, they cause an increase in temperature referred to as global warming. To fit with the language used in other subject areas, we can describe the additional greenhouse gases as 'enhancing' the greenhouse effect.
