Significant ideas:
- The atmosphere is a dynamic system that is essential to life on Earth.
- The behaviour, structure and composition of the atmosphere influence variations in all ecosystems.
What do you know?
Work on the sugar paper - record everything you already know about the atmosphere! You might think about:
- What it is
- What's in it
- What is does
- How it changes
The Dynamic Atmosphere
The Dynamic Atmosphere
- The atmosphere is a dynamic system (with inputs, outputs, flows and storages) that has undergone changes throughout geological time.
- The atmosphere is predominantly a mixture of nitrogen and oxygen, with smaller amounts of carbon dioxide, argon, water vapour and other trace gases.

Cartoon
Draw a series of images to illustrate the idea that "The atmosphere is a dynamic system (with inputs, outputs, flows and storages) that has undergone changes throughout geological time."
Systems Diagram
Draw a systems diagram for the atmosphere (boxes for storages, arrows for flows). Lucid Chart is probably the easiest way to do this. The pictures below may inspire you.
When you have finished, do the same but for a different period in geological history.
Pie Chart
Use Google Sheets to make a pie chart that accurately shows the modern composition of the atmosphere (the gases in it).
("The atmosphere is predominantly a mixture of nitrogen and oxygen, with smaller amounts of carbon dioxide, argon, water vapour and other trace gases."
- Most reactions connected to living systems occur in the inner layers of the atmosphere, which are the troposphere (0–10 km above sea level) and the stratosphere (10–50 km above sea level).
- Most clouds form in the troposphere and play an important role in the albedo effect of the planet.
- The greenhouse effect of the atmosphere is a natural and necessary phenomenon maintaining suitable temperatures for living systems.
Greenhouse Effect
From your existing knowledge, draw a picture that shows the greenhouse effect.

Go back to what you produced before. Should you change/add/remove anything?
The Albedo Effect
Look at the picture below. Write a comment on this Padlet to say:
- What the image shows.
- Where you find most clouds.
- How this could be relevant to the temperature of the earth.
- Any other 'hmm that's interesting!' thoughts this inspires.
