Key Supporting Details
These are the strong pillars that hold up the main roof!
They tell what the whole section is mostly about.
If you take them away, the author’s big point collapses.
Connects directly to the title and heading.
💡 Ask: "Does this detail prove the author's main message?"
Interesting Extra Facts
These are fun decorations that make reading enjoyable!
They are 100% true and fascinating!
BUT they only describe one tiny detail or fun fact.
STAAR questions use them as trap answer choices!
⚠️ Trap Alert: "Just because it's true doesn't mean it's the Key Idea!"
Formula: Topic + What Key Details Mostly Teach Us = KEY IDEA

Teacher Modeling: The Anglerfish
Watch Lenny evaluate details
Excerpt: The Anglerfish
Deep in the pitch-black ocean, female anglerfish use a glowing bulb to catch prey. The light dangles from a long spine above its mouth. Small, curious fish swim close to inspect the glowing blue-green ball. In a flash, the anglerfish snaps its razor-sharp jaw shut. Female anglerfish can grow up to three feet long, while males are only the size of a teacup.
Supporting Detail
"A glowing light dangles above its mouth to lure fish."
Why: Shows HOW it hunts in the dark!
Interesting Extra Fact
"Males are only the size of a small teacup."
Why: Fascinating size fact, but doesn't explain hunting!
⭐ Model Key Idea:
The anglerfish uses a glowing lure to catch food in the dark ocean.

Read Aloud with Partner:
"Flashlight fish have special light organs directly under their eyes. They use these glowing lights like headlights to spot food, signal to friends, and scare away hungry enemies. If danger approaches, the fish can slide a dark skin flap over the light to turn it off instantly."
Which detail best supports the idea that glowing helps the flashlight fish survive?
A
The fish have organs under their eyes.
(Location fact only - does not show how it survives)
B
Lights help them spot food and scare predators.
(Pillar detail proving survival advantages!)
Quick Crew Check: Choice B proves how and why the light keeps the fish alive!

Glow in the Deep: Secrets of the Midnight Zone
1 Over three thousand feet beneath the ocean’s surface lies the midnight zone. In this deep world, sunlight cannot reach. The water is ice-cold, and the darkness is total. Yet, if you traveled down into this abyss, you would see magical flashes of blue, green, and gold. Most creatures living here have a superpower called bioluminescence, which means they can make their own glowing light.
2 Many midnight zone animals rely on their light to find food in the black water. For example, the anglerfish carries a glowing lure that dangles right over its sharp teeth. Small, curious sea animals swim straight toward the light and become dinner. The flashlight fish has glowing bean-shaped pouches beneath each eye that shine forward like car headlights, helping it spot tiny prey swimming nearby. Without this living light, these predators would starve in the dark.
3 Other ocean animals use bioluminescence as a clever defense against predators. When a hungry fish chases a deep-sea opossum shrimp, the shrimp shoots a cloud of glowing blue liquid into the hunter’s eyes. The flash blinds the predator, giving the tiny shrimp time to dart away. Similarly, the deep-sea comb jelly pulses with bright rippling lights to startle enemies and escape before being caught.
4 Exploring the midnight zone is difficult because the deep water has crushing pressure. Today, scientists send robotic submersibles equipped with sensitive cameras to film these glowing marvels. Marine biologists believe thousands of undiscovered creatures are still waiting in the dark sea.

Story #1: The Giant Isopod Ocean Floor Scavenger
Investigative Clues:
It crawls along the pitch-black ocean floor searching for fallen whale carcasses.
Its tough armored shell protects it from freezing temperatures and crushing pressure.
It can survive up to five years without eating a single bite when food is scarce.
Your Key Idea Headline (What do all 3 clues prove about the giant isopod?):
Story #2: The Vampire Squid Oxygen-Deprived Abyss
Investigative Clues:
It lives in the "shadow zone" where there is almost zero oxygen in the water.
Its slow-moving body uses very little energy so it does not need much oxygen to breathe.
It feeds gently on floating bits of organic dust rather than actively chasing prey.
Your Key Idea Headline (What do all 3 clues prove about the vampire squid?):
Story #3: The Yeti Crab Hydrothermal Vents
Investigative Clues:
It lives huddled around boiling-hot underwater volcanic geysers to stay warm.
Its furry claws trap deep-sea bacteria that it harvests and eats for food.
Its pale white color and lack of eyes suit life where sunlight never penetrates.

15-Second Corrective Reroutes for Common Misconceptions
Misconception: Student chooses an interesting fact because "it was the coolest sentence."
Teacher Prompt: "That IS super cool! But if you deleted that sentence, would the author still be teaching you how the animal catches food? Yes! So that's extra glitter, not a pillar!"
Misconception: Student writes a 1-word topic like "Fish" as the key idea on the SCR.
Teacher Prompt: "Good start on the topic! Now add the action: What does the text teach us about WHAT those fish DO with their lights?"
