Teacher Does
Show picture of sunlight hitting the Earth in various
locales (e.g., desert, mountain, tropical area). Ask
student what they recall about the solar energy in this
picture
Ask what they think happens to the solar energy once
it hits the Earth. Write and then discuss with partner
Class discussion
Student Does
Discuss what they recall
Write in notebooks and share with
partners
Build on student ideas from the Engage (particularly if
someone thinks the energy goes “back up”
Ask if anyone has any experience with thermal energy
“going back up/out”
Give examples: heat rising in a two
story house; heat waves on the road
Provide prompt: working in Africa—have different
lands to determine how the energy acts: lampland,
candelland, waterland.
Direct students to work in groups of 3-4:
Display Student Learning Target: I will complete an
investigation to illustrate how energy from the sun is
transferred from different surfaces to the atmosphere
Remind students this is their “job” for the lesson and
they will know when they are done when they can:
- Identify the elements of an investigation in their own
work
- Use their work to explain (in words or labeled
diagrams) what heat/energy was transferred and from
where.
Contribute whole class to prompts
asking for elements of an
investigation.
Review and/or record in notebooks.

What will you need to do to plan your investigation?
[Define the question or problem, Plan a way to record

be qualitative). What patterns do they notice?
Ask how they could improve their data

Provide students with reading. Question for the
reading:
How does thermal energy re-enter the
atmosphere?
Use *, ? ! to code the reading
Read and discuss what they found
Thermal energy transfers
through radiation, conduction
and convection. Most thermal
energy that hits the Earth is reradiated into the atmosphere
Explain
Based on reading, and experimental data, revise
your model and create an explanation for how
energy moves in the atmosphere
Display whiteboards/posters or
writing explaining the movement
Different parts of the Earth
absorb and release thermal
energy differently. High
temperatures release energy at
a faster rate
Elaborate**
Show video of convection currents
(explain that water and air are fluids—so this
movement in water is similar to what would occur in
air)
Observe, ask questions
Rising air falls as it cools,
creating convection currents
CA NGSS Rollout #2: 5E Learning Sequence Example Grades 6-8
ask students to think about how what they observed
could impact their model; ask them to add to their
model
Drawing show that the heated air
cools and falls down
Evaluate
Ask what would happen if the hot land (i.e., lampland)
was next to the cool land (i.e., waterland). Ask
students to discuss and then draw and explain their
idea
Recognize that this would set up a
convection current like in the video.
Thermal energy re-radiates into the
atmosphere as hot air, which then
cools and falls down, creating the
current.
New Engage
Show satellite image of global winds. Ask how that
relates to their convection currents
Pose ideas, models
Thermal energy transfer can be
modeled to understand wind.
** Note: this elaborate could also go into another learning sequence on convection based on understanding density, temperature and pressure
