TEACHER’S GUIDE—ADVENTURER
You’ve asked and we’ve listened to your requests for grade
specific editions of National Geographic Explorer magazines. You
can now order an edition of Explorer that is written specifically for
your students. You’ll find information about the new Explorer in
this month’s wrap. Why wait? Order today and keep your students
learning and exploring.
We’ve got a new look, and more!
Now there’s an edition written
for your grade level.
Pioneer, Grade 2
Trailblazer, Grade 3
Winter Weather
Time passes and the seasons change.
It’s winter now, and the wolf pups
are the same size as the adults in the
pack. A fresh layer of snow has fallen.
The morning is cold, but the wolves
are not. Their thick, winter coats keep
them warm.
As the alpha male walks by one of
the pups, the pup bends down low to
be respectful. The pup’s brother rolls
onto his back. This is also a sign of
respect. The alpha male stands over
the second pup and licks its face. The
pup whines softly. The beta has taught
these pups well. The pups must always
respect the alpha male.
On Alert
The cougar attack is a troubling sign.
At times, wolves must share their
territory with other predators. These
predators, like bears and cougars, eat
the same food as the wolves do. If
prey becomes hard to find, the wolves
could be in danger.
The loss of a member of the pack
hits the wolves hard. In the weeks that
follow, they keep to themselves. They
mourn their lost friend.
Wolf Pack
Wolves live together in small groups, like families.
Being part of the pack helps wolves survive.
Alpha
The alpha male is the leader of the pack.
He makes the decisions and is responsible
for the other wolves. The alpha female is
his mate.
Beta
A wolf is safer in a pack
than on its own.
The beta is the second in command.
The beta can also be the peacekeeper
and often watches over the pups.
Defending the Pack
The alpha male looks at the wolves
in the pack. One member is missing.
Something is wrong.
Leaving the beta to care for the
pack, the alpha male heads out to
search. It doesn’t take long for him
to find the missing wolf. It’s dead.
A cougar has killed it.
The alpha male lets out a long howl
to call the pack. The wolves come
running, then stop short at the sight
of the dead wolf. The pups bark in
alarm. They’re frightened.

Pathfinder, Grade 4
Omega
The omega is the lowest ranking wolf.
The other wolves often pick on the
omega. However, the omega is very
important to the pack.
Pups
The pups are the youngest wolves.
The other wolves teach them the
ways of the pack.

NATIONAL GEOGRAPHIC EXPLORER
Adventurer, Grade 5
Finding Food
Wolves play a vital role in their food web. A
food web shows how energy flows through an
ecosystem. Every organism needs energy in
order to live. Plants get energy from the sun,
for example. Then some animals, like elk, eat
the plants. Then some animals, like wolves, eat
the elk.
A food web is a sign of how healthy an
ecosystem is. If one part of the web changes,
everything in that ecosystem changes, too.
Without wolves, the number of elk would
increase. The elk would eat more plants. Then,
eventually, the elk wouldn’t have enough food.
Searching for Energy
Time passes, and the seasons change. It’s winter
now, and the wolf pups are the same size as
other members of the pack. A fresh layer of
snow has fallen. The bitter morning is cold, but
the wolves are not. They’re kept warm by their
thick, winter coats.
The wolves are shaking snow off of their
backs and stretching. As the alpha male walks
by one of the pups, the pup crouches down low
to be respectful. The pup’s brother rolls onto
his back, showing his stomach. This is also a
sign of respect. The alpha male stands over the
second pup and lick’s the pup’s face. The pup
whines softly. The beta has taught these pups
well. The role each wolf plays is constantly
reinforced by interactions like these.
The alpha male looks at the pack and sees
that one member is missing. He sniffs the air.
His eyes narrow. Something’s wrong.
Leaving the pack in the care of the beta, the
alpha male heads out to search for the missing
wolf. It doesn’t take long for him to find the
missing wolf. A cougar has attacked and killed
it. This is a troubling sign.
At times, wolves must share their territory
with other top predators. These predators, like
bears and cougars, rely on the same prey as the
wolves for food. If prey becomes scarce, these
predators could threaten the whole pack.

NATIONAL GEOGRAPHIC EXPLORER
Mourning a Member
Seeing the missing wolf, the alpha male lets out
a long howl, calling the rest of the pack. The
wolves come running, then stop short at the
sight of the dead wolf.
The pups bark in alarm. There aren’t many
animals that can kill a wolf. A cougar is one of
them. Now the pack has to watch out for it.
The loss of a member hits the pack hard.
In the following weeks, the wolves don’t play
or interact much. They keep to themselves,
mourning their lost friend. From time to
time, they howl, but they howl alone. It’s a sad
sound. The pups seem unsettled. The pack feels
unbalanced now.
A Wolf’s Food Web
Wolves are apex predators. They have very few
competitors for food.
A wolf’s thick, winter coat
protects it from the cold.

• Some living things use chemical reactions to make
their own light. This light is called bioluminescence.

• Organisms create light for several reasons. The light
can help them to hunt or fool predators or prey. It
can help them flee from predators. Some organisms
use the light to warn others of their kind or as a
form of camouflage that allows them to blend in
with the environment.

Flash, Glimmer, and Glow: Background
Fast Facts
• Bioluminescence is an adaptation in which light is
produced through a chemical reaction in a living
organism. Most bioluminescent organisms live in the
ocean. This includes fish, bacteria, and jellies. Fireflies
and some specie of fungi are bioluminescent organisms
that live on land.
• The light created through bioluminescence is known as
"cold light." This means that less than 20 percent of the
light generates heat.
• The color of this light depends on how molecules in
the light-producing compound are arranged. A firefly's
light is yellow. In a lanternfish, it's green.
• B
ioluminescent animals that live in the ocean typically
produce a blue-green light. Most marine animals can
only see within the blue-green portion of the visible
light spectrum.
• W
hen a brittle star is threatened, it detaches a glowing
arm. The arm crawls one way and the animal goes the
other. It can regrow the arm.
• F
ireflies use their bioluminescence to attract mates.
• Th
e glow of bioluminescent bacteria on the ocean is
sometimes bright enough to be spotted by satellites
orbiting Earth.
• Bioluminescence can help animals defend themselves.
Using light, they can fool other animals, hide, and
escape from predators.
• Squid that live near the ocean surface squirt out dark
ink so they can hide and escape predators. Many that
live in deep ocean waters eject a sticky bioluminescent
substance to get away.
• Counterillumination is a kind of camouflage created
with bioluminescence. The hatchetfish uses this. It has
downward-pointing organs that not only produce light
but can adjust the amount of light produced to match
sunlight coming from above. This disguises shadows
and makes the fish invisible to predators looking up
from deeper waters.
• Some animals use bioluminescence to hunt. The
anglerfish, for example, is armed with a mouth full of
sharp teeth. It's also got a long filament growing out
of the top of its head. At the end of that filament is a
glowing ball. Unwitting prey are attracted to the light.

Back to Life: Overview
Summary
Next Generation Science Standards
• The Gorongosa National Park was a casualty of a
15-year war in Mozambique, Africa. The ecosystem,
which had previously teemed with life, was nearly
destroyed.
• Disciplinary Core Idea: Interdependent
Relationships in an Ecosystem—The food of almost
any kind of animal can be traced back to plants.
Organisms are related in food webs in which some
animals eat plants for food and other animals eat
the animals that eat plants. Some organisms, such
as fungi and bacteria, break down dead organisms
(both plants or plants parts and animals) and
therefore operate as “decomposers.” Decomposition
eventually restores (recycles) some materials
back to the soil. Organisms can survive only in
environments in which their particular needs are
met. A healthy ecosystem is one in which multiple
species of different types are each able to meet
their needs in a relatively stable web of life. Newly
introduced species can damage the balance of an
ecosystem.
• Ten years ago, a philanthropist funded a group of
scientists to restore the park to its former glory.
Although they still have a ways to go, the scientists
have seen increased biodiversity among the plants,
animals, and other organisms living here.

Back to Life: Background
Fast Facts
• Mozambique is located between South Africa and
Tanzania on the southeastern coast of Africa. The
Indian Ocean lies between Mozambique and the island
of Madagascar.
• In 1975, Mozambique became an independent country.
This event marked the end of nearly five centuries as a
Portuguese colony. But just a few years later, civil war
broke out. It lasted for 15 years. The war had many
casualties, including Gorongosa National Park.
• Gorongosa National Park is a 4,067-square km
nature reserve that lies relatively midway between the
country's northern and southern borders. It is located
at the end of Africa's Great Rift Valley. The park's
ecosystem includes savannahs, woodlands, and rain
forests.
• I n 1976, there were about 500 lions in Gorongosa
National Park. Today, between 30-50 lions live within
the park's borders.
•M
uch of the water that sustains the Gorongosa
ecosystem trickles down from Mount Gorongosa, a
1,863-meter peak that only became an official part of
the park in 2010.
•G
orongosa did have one large predator escape the
war with its population intac­t—crocodiles. The park's
extensive network of rivers and lagoons is the perfect
home for thousands of crocs.
• Before the war, Gorongosa was one of the richest
wildlife refuges in the world. Between war, hunters,
poachers, and logging, the park was devastated.
Habitats were destroyed, and many of the park's large
animal populations plummeted by 90 percent or more.
• Losing so many large animals had a ripple effect on the
entire ecosystem. Grasses, shrubs, and some forests
grew thicker. Food chains were disrupted. With so
many missing pieces, the food web was in disarray.
• The park lingered in this state for nearly a decade.
Then, with the backing of American philanthropist
Greg Carr, a team of scientists set out to restore
Gorongosa's ecosystem. There is still a long way to go,
but now—just over a decade later—the park is on the
road to recovery.

Exploring Words With Examples
1. Display the Wordwise words on page 17 of the
projectable edition. Review each word and its
definition with the class. Make sure all students have a
thorough understanding of the terms.
2. Divide the class into small groups. Instruct students
to make a logical connection between each photo and
one or more vocabulary words. For example, students
may say that a lion is a carnivore, but when it dies,
scavengers could eat its remains.
3. Once groups have identified their examples, pair up
two groups so they can share their ideas. Are any
of their examples alike? Which ideas are different?
For those examples that are different, do both ideas
manage to successfully convey an accurate definition
of each term?
4. When groups have finished comparing their results,
rejoin as a class. Discuss with students how attaching
each word to an example helped them better
understand each term.

Summary
Materials Needed
• Astronauts working at the International Space
Station use technologies that help people on Earth.
For example, they can take infrared images that
show farmers where healthy plants are growing.
They can also pick up signals from ships, allowing
them to track vessels' movement on the open ocean.
• plain

• Some of the technologies used in space can also be
used on Earth. People living in remote areas are
now using the same portable ultrasound machine
that astronauts use in space. This allows them to get
medical help when doctors are far away.

Space Lab: Background

Facts
• Th
e ISS is about the size of a football field.
• The International Space Station is a laboratory that
orbits Earth. Since the first mission to the ISS, which
launched on October 31, 2000 and reached the space
station on November 2, humans have continuously
inhabited the space station.
•A
lthough developed to primarily take images of
agricultural areas, ISSAC has also taken images of
natural hazards and disaster areas.
• Astronauts aboard the ISS conduct research stemming
from all areas of science. They study the impact of
space travel on the human body, and they test new
technologies that may aid in future missions. Many of
the technologies they investigate help people on Earth.
Some are even used by people on Earth.
•M
any people lack access to clean drinking water. Using
advanced water filtration and purification systems
developed for the space station, they can now tap into a
safe water supply.
• The International Space Station Agricultural Camera
(ISSAC), for example, takes infrared and visiblelight images of forests, grasslands, and agricultural
fields in the North American Great Plains. Farmers
and ranchers analyze the images to make informed
decisions about their crops and livestock.
• With the Advanced Diagnostic Ultrasound in
Microgravity (ADUM), crew members can take highquality ultrasound scans if they become injured or
ill. They can send the scans to Earth, where a ground
flight surgeon can evaluate the scans and diagnose
the problem. Doctors on Earth can use this same
technology to help people who live in remote areas far
from medical care.
• The Vessel ID System is a space-based radio receiver
attached to the external handrails of the space station.
This device makes it easier to monitor the location of
ships on the ocean. The system collects signals from
ships on Earth and bounces them back to a receiver
on the ground. It has relayed position reports tracking
more than 22,000 ships in one day.
• Experiments with the Vessel ID System also help
astronauts. The adaptor connecting the system to the
ISS is new. If successful, it would give astronauts a
new way to attach payloads to the ISS when they are
working outside the space station.
