Grade 6
5E lesson flow
01
Engage
6 min
Teacher Does
Compare raincloud, meteor and aurora observation locations.
Students Do
Predict which is highest and why.
Ask
- Can one altitude fit all three observations?
Look For
Altitude is meaningful to each.
02
Introduce model
11 min
Teacher Does
Present five thermal layers with approximate ranges.
Students Do
Sketch layer boundaries and annotate key features.
Ask
- Are these hard walls?
Look For
Boundaries approximate and varying.
03
Read evidence
10 min
Teacher Does
Explain ozone and UV, meteor entry, auroras and thin air.
Students Do
Classify altitude event cards and explain one clue.
Ask
- Can satellites occupy one layer only?
Look For
No single satellite layer.
04
Interactive mission
11 min
Teacher Does
Guide choice, sort and sequence screens.
Students Do
Decide based on readings, receive and apply feedback.
Ask
- Which measurement supports your claim?
Look For
Accurate use of altitude data.
05
Model limits
8 min
Teacher Does
Compare equal-height teaching diagram with a scaled model.
Students Do
Explain one misleading property of the simplified drawing.
Ask
- Why can the thermosphere be hot but not feel warm?
Look For
Very thin gas and limits of temperature analogy.
06
Independent assessment
9 min
Teacher Does
Assign new Orion worksheet and exit ticket.
Students Do
Use fresh data and challenge a satellite misconception.
Ask
- Which layer contains Sensor C?
Look For
Evidence-based reading.
Student goal
I can model Earth's five atmospheric layers and support layer claims with altitude evidence and physical conditions.
Learning objectives
- Identify the approximate altitude ranges and key phenomena associated with Earth's five major atmospheric layers.
- Analyze evidence for how air density, weather and temperature trends change with altitude without assuming all temperatures rise or fall together.
- Explain what a layer model shows and where its boundaries and phenomena overlap.
Materials
- Large altitude diagram (0, 12, 50, 85, 600 km)
- Layer event cards
- Colored pencils
- Simple altitude data table
- Printed Sky Probe Orion worksheet
Before class
- Check that diagrams use APPROXIMATE, variable layer boundaries.
- Include a to-scale and simplified-model comparison.
- Prepare altitude reading cards separate from worksheet observations.
- Clarify that some satellites orbit in the thermosphere.
- Avoid direct-sun experiments; this is a data/model investigation.
Safety & supervision
Review these precautions before students begin the investigation. Follow your school's safety procedures.
- Do not launch balloons or rockets as part of this class activity.
- Never stare at the Sun; use classroom diagrams.
- Use only preapproved data and illustrations.
Prior knowledge
- Earth is surrounded by gases.
- Height above Earth's surface can be measured in kilometers.
- Air and sunlight interact to produce weather.
Vocabulary
- atmosphere
- The envelope of gases surrounding Earth, gradually thinning into space.
- troposphere
- The lowest major atmospheric layer, where most weather takes place.
- stratosphere
- The layer above the troposphere that contains most atmospheric ozone.
- mesosphere
- The layer roughly 50–85 km high, where many small meteoroids burn up.
- thermosphere
- A very thin-air layer roughly 85–600 km high where temperature can increase greatly with altitude.
- exosphere
- The extremely thin outer region of Earth's atmosphere fading gradually into space.
- ozone
- A gas made of three oxygen atoms; high-altitude ozone absorbs much harmful ultraviolet radiation.
- air density
- How much mass of air is found in a given volume; it usually decreases with altitude.
Differentiation
- Provide a labeled altitude strip and color-coded key.
- Offer a sortable table before independently naming layers.
- Provide data frames: 'At __ km this lies in __ because __.'
- Extension: chart how temperature direction alternates by layer.
Assessment
- Name five layers in order.
- Map new altitude data to layers.
- Explain ozone's function and air density.
- Complete fresh worksheet and limits of model explanation.
Exit ticket
Why would an aurora be higher than a rainstorm in a simplified atmosphere model?
Extension
Using NASA profiles, contrast changes in temperature and air density with altitude.
