Journey to the Center of the Sun
Today's Mission
01
Identify the Layers
Discover what's hiding inside our closest star.
02
Track the Energy
Map a photon's million-year journey from the core to space.
Quick Sketch
What is inside the Sun?
On your worksheet, draw what you think the inside of the sun looks like. Is it solid? Liquid? Gas? What's going on in there?

Watch for the Pinball analogy!
1. THE CORE
Temperature: 27 million degrees Fahrenheit!
Action: Nuclear Fusion. Atoms smash together to create energy.
Energy is "born" here as light particles called Photons .
2. RADIATIVE ZONE
The Pinball Effect: Energy bounces off atoms like a pinball.
The Slow Lane: It can take up to 1 million years for light to escape this layer!
3. CONVECTIVE ZONE
The Lava Lamp: Hot gases rise, cool down, and sink back down.
The Express Lane: Energy moves much faster here, bubbling to the surface.
Main Activity: Comic Strip
Create 4 Panels
1 The Core: A photon is born!
2 Radiative Zone: Bouncing pinball!
3 Convective Zone: Bubbling gas!
4 Space: Zooming to Earth!
Character Goal:
Draw your photon as a character. Give them a personality! Are they excited? Tired of bouncing? Ready for Earth?
Use colored pencils to match the solar layers!

Duration
45 MIN
Learning Objective
Students will be able to describe the three internal layers of the sun (Core, Radiative Zone, Convective Zone) and illustrate the journey of solar energy from the core to the surface through a multi-panel comic strip.
Background Knowledge
The Sun is a star powered by nuclear fusion. This energy takes an incredibly long time to traverse the dense internal layers before traveling to Earth at the speed of light.
Materials Needed
Solar Powerhouse Slides
Photon Journey Worksheet
Colored Pencils (Yellow, Orange, Red, Purple)
Computer/Projector for Video
Instructional Sequence
5 MIN
Warm-up: Predictions
Students draw their mental model of the sun's interior on the worksheet. Encourage them to guess what the center is like.
10 MIN
Video Observation
Watch segment 1:29 – 2:40 . Pause at 2:05 to discuss the "pinball" analogy.
"How is a pinball like energy in the radiative zone? Why does hitting atoms slow it down?"
25 MIN
Main Activity: Comic Strip
Students follow the 4-panel guide to create "A Photon's Journey." Emphasize character design—give the photon a face or a "mood" for each zone.
5 MIN
Closure: The Million-Year Lag
Turn and talk: "Why does it take so long inside, but so short outside?" Answer: Density and the pinball effect.
Worksheet Answer Key
Guided Notes
Core: ...nuclear fusion (or atoms smashing).
Radiative Zone: ...pinball.
Convective Zone: ...gas / bubbles.
Comic Panel Expectations
Panel 1: Show high heat, purple/white light, fusion.Panel 2: Ziz-zagging path, "Ouch!" or "Boring!" dialogue.Panel 3: Circular motions, bubbling, rising to surface.Panel 4: Straight line path, speeding through space.
Reflection Answer:
Inside the sun, the layers are so dense that light particles (photons) constantly crash into atoms and bounce away, which slows them down (The Pinball Effect). In space, there is nothing to crash into, so light travels at its full speed.
