Expedition Pacing
1
Rainforest Layers (RI.1)
Focus: Training students to look back into the text for "proof". Use the "Search & Find" strategy.
Discussion Prompt: "What part of the sentence tells us exactly how high the trees grow?"
2
Desert Survival (RI.2)
Focus: Differentiating between a "topic" (Deserts) and a "Main Idea" (How animals survive). Use the Table Top method.
Discussion Prompt: "If we took away the detail about nocturnal animals, would our table still stand?"
3
Deep Sea Detectives (RI.4)
Focus: Using the IDEAS acronym to find context clues. Modeling direct definitions vs. synonym clues.
Discussion Prompt: "Does the author give us the definition right there in the text, or do we have to infer it?"

Arctic Wonders (Review)
Focus: Synthesis of all skills. Students should work more independently on the worksheet to show mastery of all three standards.
Goal: Official "Reading Expert" certification via the exit ticket.

Expedition
Focus Standard: AZ 3.RI.1 - Asking & Answering Questions
Today's Mission
The Goal
I can ask and answer questions about a text, referring to the text for the answers.
Ask
Wondering "Who, What, Where, When, Why, and How"
Answer
Finding specific evidence inside the reading
Step 1: The Forest Floor
Investigation Text
The bottom layer of the rainforest is the forest floor. It is very dark here because the tall trees above block most of the sunlight. Only about 2% of sunlight reaches the ground! Because it is dark and damp, plants grow slowly. Many large animals, like jaguars and anteaters, wander this floor looking for food. Small insects and fungi also live here, helping to break down fallen leaves and branches.
Ask a Question
"Why is it so dark on the forest floor?"
Answer with Evidence
"It is dark because the tall trees above block most of the sunlight."
Step 2: The Understory & Canopy
Expedition Log
Above the floor is the understory. It is filled with low light and large leaves that catch any sun they can. Higher still is the canopy. This layer is like a leafy roof that covers the forest. It is home to most of the rainforest's animals, such as monkeys, sloths, and colorful birds. The canopy is very thick and protects the forest below from heavy rain.
Scout Challenge
What question can you ask about the canopy?
Think about "Who lives there?" or "What does it do?"
The "Search & Find" Strategy
1
Curiosity
Wonder about something specific in the text as you read.
2
Location
Scan the text for "key words" that match your question.
3
Proof
Use the text's words to answer. If it's not in the text, it's not evidence!

The Emergent Layer
The very highest part of the rainforest is called the emergent layer. Here, giant trees tower above everything else, reaching heights of up to 200 feet! Because these trees are so tall, they get more sunlight than any other part of the forest. However, they also have to face strong winds and heavy heat from the sun. Many birds of prey, like the Harpy Eagle, live in these treetops to spot their food from high above. Colorful butterflies also flutter around the emergent layer, drinking nectar from the flowers that grow on the branches.
1. Answer the Question: How tall can trees in the emergent layer grow?
Underline the sentence in the text where you found the answer.
2. Answer the Question: Why do Harpy Eagles live in the emergent layer?
List one piece of evidence from the text to support your answer.
3. Ask Your Own: Write a "Why" question about the emergent layer.

Desert Survivors
Investigate
Plants in the desert have developed amazing ways to survive without much water. The Saguaro cactus has a thick, waxy skin that prevents water from escaping. Its shallow roots spread out wide to soak up every drop of rain. Other plants, like the creosote bush, have tiny leaves that lose less water to the heat. Some desert flowers wait as seeds for years until a big rainstorm finally helps them bloom.
Main Idea?
Desert plants have special ways to survive in dry weather.
Detail Check:
Saguaro has waxy skin.
Roots spread wide for rain.
Tiny leaves lose less water.

Creatures of the Heat
Animals that live in the desert have unique behaviors to help them stay cool in the extreme heat. Many desert animals are nocturnal, which means they sleep during the hot day and only come out at night when it is cooler. Other animals, like the Fennec fox, have giant ears that help heat escape from their bodies. Some lizards burrow deep into the sand to find a cool spot away from the sun. The Gila monster even spends most of its life underground to avoid the scorching Arizona sun.

Abyssal Mysteries
Investigation Text
In the deep ocean, some creatures have the ability of bioluminescence. This means they can produce their own light inside their bodies. The Anglerfish uses this light as a lure, which is a tool used to trick or attract prey into coming closer. Because the deep sea is so cold, many animals have a very slow metabolism, using energy carefully so they don't have to eat often.
Word: Bioluminescence
Clue: "produce their own light"
Word: Lure
Clue: "trick or attract prey"

The Hydrothermal Vents
Deep on the ocean floor, there are strange openings called hydrothermal vents. These vents are like underwater volcanoes that spew out scalding water, which is extremely hot and can reach over 700 degrees Fahrenheit! Even though the water is boiling, many tiny organisms thrive in this environment. Instead of dying, they grow very well and create a busy community. These creatures get their energy from chemicals in the water through a process called chemosynthesis. Unlike plants that use the sun, these creatures use chemicals to make food.

Life on the Ice
Mastery Text
The Arctic is a frozen desert at the top of the world. Polar bears are the kings of this land, using their thick white fur to camouflage or blend in with the snow. This helps them sneak up on prey. Under the fur, their skin is actually black to absorb heat from the sun. Polar bears are also excellent semi-aquatic mammals, meaning they spend time both on the ice and swimming in the freezing water. Because of the melting ice, polar bear survival is becoming more difficult every year.

The Frozen Tundra
The Arctic tundra is a unique habitat that remains frozen for most of the year. Plants here must be hardy, which means they are strong enough to survive the brutal winds and icy temperatures. Because the soil is always frozen, large trees cannot grow. Instead, small shrubs, mosses, and lichens cover the ground like a carpet. Many animals that live here have insulation, such as thick layers of fat or fur, that traps heat close to their bodies to keep them warm. During the long winter, the sun never rises, leaving the tundra in total darkness for months.
