Our Protective Atmosphere

Let's explore the invisible shield that makes our planet liveable. This topic takes your pupils on a journey from the ground we stand on to the edge of space, discovering the secrets of our protective atmosphere.

Atmosphere in a Jar

Pupils create a model of the atmospheric layers in a clear jar using different coloured liquids of varying densities (like honey, golden syrup, washing-up liquid, coloured water, and oil). Each liquid represents a layer, helping to visualise their distinct and stacked nature.

Identify the main gases that make up the Earth's atmosphere.

Facilitation Tip

Prepare pre-measured amounts of each liquid to minimise mess and ensure the layers settle correctly.

What to look for

Use an 'Exit Ticket' where pupils must write down two things they learned about the atmosphere and one question they still have before leaving the class.

Activity 02

• Jigsaw
• 30 min · Pairs

Gassy Graphs

In pairs, pupils use percentage data on the composition of the air (78% Nitrogen, 21% Oxygen, etc.) to create their own pie charts. This activity integrates numeracy skills and helps them grasp the overwhelming prevalence of nitrogen.

Explain the role of the ozone layer in protecting life on Earth.

Facilitation Tip

Provide a template circle marked with 100 increments to help pupils accurately segment their pie charts.

What to look for

Pupils draw, colour, and label a diagram of the Earth and its atmospheric layers. They must include at least one key feature for each layer (e.g., a plane in the troposphere, the ozone layer in the stratosphere).

Activity 03

• 60 min · Small Groups

Ozone Layer Investigators

Pupils work in small groups to research the function of the ozone layer, what caused the 'hole' in it, and how international cooperation helped to fix it. They can prepare a short news report to present their findings to the class.

Compare the characteristics of the troposphere and the stratosphere.

Facilitation Tip

Provide child-friendly websites or printed fact sheets to guide their research effectively.

What to look for

Provide a 'KWL' chart at the beginning and end of the topic. Pupils fill out what they 'Know', 'Want to know', and finally, what they 'Learned' to reflect on their own progress.

A few notes on teaching this unit

Start with tangible, hands-on models like the 'Atmosphere in a Jar' to make abstract concepts concrete. Use clear analogies, comparing the ozone layer to sun cream or the greenhouse effect to a cosy blanket. Encourage pupils to ask questions and use 'Think-Pair-Share' to build a shared understanding before moving to more complex ideas.

Through these activities, your pupils will be able to visualise the atmosphere's layers, understand its composition, and explain why this blanket of air is essential for all life on Earth.

Watch Out for These Misconceptions

• The atmosphere is just empty space or 'air' with nothing in it.

  The atmosphere is a mixture of different gases that have mass and take up space. Air pressure is the weight of these gases pushing down on us, which is why it's harder to breathe high up a mountain where the air is thinner.

• The hole in the ozone layer causes global warming.

  These are two separate issues. The ozone layer protects us from the sun's harmful ultraviolet (UV) rays, like sun cream. Global warming is caused by the 'greenhouse effect', where certain gases trap heat in the atmosphere, like a blanket.

• Weather and climate are the same thing.

  Weather is what the atmosphere is doing in the short term, for example, if it's rainy today in Dublin. Climate is the average weather pattern over a long time, for example, the fact that Ireland generally has a mild, wet climate.
