Our Mission
The mission of Spigot Science Magazine
is to help children understand how and
why the world works and to inspire young
minds to be curious and thoughtful
stewards of the world that will be theirs
one day.
From the Publishers
It’s true. Science is all around us. Actually
we live in science: inside a niche that’s inside a
habitat, that’s inside an ecosystem, that’s inside a
biome. We both live in the Deciduous Forest
Biome. Here in our biome we enjoy all four
seasons. We love making snowmen in winter,
planting our gardens in spring, collecting the
colorful leaves of fall, and playing on the beach
and in the ocean in summer. Right now we are
awaiting the arrival of spring. (See poem, p.14.)
Last summer, Dave visited several
different biomes in Alaska. He saw icebergs
calving (see WATER issue, p.20) and a rainforest
where it is cold. He came back with lots of
pictures and a great interview (see p. 17). It got
us thinking…what other biome have we ever
seen? Up until now we hadn’t realized that the
ocean itself is a biome. Getting ready for this
Ecosystems issue, we learned that the ocean is
one huge biome made up of many ecosystems.
Valeria lives about a half hour from that
gigantic biome—the Atlantic Ocean at the Jersey
shore. She took her dog, Star, there to pose at the
Ocean Biome (see picture below). Learn about
other biomes in two articles on pages 10 and 13.
In this issue you’ll also find a lot of
information about how energy is used in the food
pyramid (p. 7) and how you can discover
habitats. You’ll learn about the snow geese in
Valeria’s backyard habitat on page 9.
There is so much more about biomes,
ecosystems, habitats, and niches in this issue.

Scientists today have an amazing
tool to use to help them capture and
save their discoveries. It’s the camera!
Scientists use cameras to document
their discoveries, to prove their
hypotheses, and to present their findings
to others. Since science is all around
us, everyone can use the camera to
think and act like a scientist.
In 1871, a professional
photographer, William Henry Jackson,
traveled with a survey team that was
exploring and mapping the West. With
his camera he took pictures of the land
formations of the Yellowstone area in
the Wyoming Territory. At that time no
member of Congress had ever seen
Yellowstone. They had only heard
amazing stories of wildly colored
springs, magnificent waterfalls and
strange rock formations in an almost
mythical ecosystems. (See Ecosystems
on the next page.)
Because of Jackson’s splendid
photographs of Yellowstone’s unique
ecosystem, in 1872, Congress
designated Yellowstone as the first
national park in America. Jackson’s
photographs helped to save a majestic
ecosystem for posterity.
Taking pictures gives us a great
way to show changes. Certainly you
have pictures of yourself taken through
the years. When you line them up, it’s
fun to see how you have grown. Taking
pictures of a garden throughout the year
shows how weather, flower and plant,
and sun and shade changes. On the
next field trip you take, make sure you
have your camera along. Take pictures
along the way, write about them, and
share them. You’ll be thinking and
acting like a scientist.

Divisions of our Earth
The Earth is made up of many different places—high mountains,
deep ocean gorges, rainforests, and deserts. These places have
different geographies (physical features like mountains and plains)
and climates (weather patterns including temperature, precipitation,
and wind). In each of these places, there are plants and animals that
interact with each other.
A biome is a large area that has similar plants, animals, and climate.
Scientists mostly agree that there are at least ten large biomes on our
planet Earth. Think about how unlike a desert and a rainforest are.
Deserts are very dry, getting less than 20 inches (51 cm) of rainfall a
Rainforests, however, are very wet with a lot of precipitation –
between 50 to 260 inches (125 to 660 cm). Both of these biomes are
very warm, but the plants and animals that live there are very different
from each other. You might find a cactus plant in the desert, but you’d
never find a macaw, the brightly colored parrot of the South American
rainforests, flying there. You’d find lush, tropical trees with lots of
animals in the rainforest, but you’d never see a desert animal like a
sidewinder rattlesnake there. Biomes have unique types of plants,
animals, climates and geographies.
Plants and animals support each other in communities called
ecosystems. This word is a combination of ecology and system.
Ecology is the study of the relationship between living things and
their environment. A system is a group of interdependent parts that
together make a working whole.
An ecosystem is an area where plants and animals rely on each
other to live and reproduce. An ecosystem can be very small, like
in a tiny pond where plants provide food for fish and frogs or very
large, like the Arctic, where polar bears and sea lions live by eating
fish and other wildlife.

A habitat is like a neighborhood where things live. It has a suitable
arrangement of food, water, shelter, and space in which an animal can
live and raise a family. Within one ecosystem there may be several
habitats, some where certain animals or plants live, and others where
different species live.
A niche is what a particular species does in its habitat. It is how it uses
its environment to live, grow, and protect itself. It is its place in the community to which it belongs. Many different organisms can live side by side
in any one habitat. But no two species can occupy the same niche in the
same environment for a long period of time without depleting the resources
available to both.
In all natural environments, both living and non-living things interact. A stone may be the home of lichens
which grow on them. Ants may live in certain non-living soils. All of the Earth’s ecosystems are connected to
each other and they are always changing. Change is one of the big features of our world. As the world
changes, plants and animals adapt to new environments. This change is what makes life so exciting.

Energy in the Food Pyramid
"When we tug on a single thing in nature, we find it attached to everything else"
John Muir,
Founder of the Sierra Club, dedicated to protecting and restoring the quality of the natural and human environment.
Living organisms need energy
to live. Plants need energy to grow
leaves, and animals need energy to
breathe and move about. The
source of all energy for plants and
animals is the Sun, the star in our
solar system. The Sun transfers its
energy by light rays to the Earth. It
heats the Earth and, through the
process of photosynthesis, causes
plants to grow. Plants are the
producers of food for all other parts
of the food chain.
Secondary Consumers
Some animals eat only other
animals. These are called
carnivores. (From carno, meat;
voro, to eat) They get energy that is
second-hand. Their energy comes
from the other animals that got their
energy from the plants. These
animals are called secondary
consumers, and they feed on
primary consumers. A snake that
eats a grasshopper and a cat that
eats a mouse are secondary
Tertiary Consumers
Animals that eat secondary
consumers (the snake and the cat)
are not only carnivores. They are
also called tertiary consumers.

Even though not all the energy
is transferred between levels of
the food pyramid, it isn’t totally
lost. It changes to heat in the
atmosphere. Energy can never
be lost; it can only be changed
from one form to the other.
This is the Law of the
Conservation of Energy. See
the ENERGY issue of Spigot,
Jan/Feb 2009, at

Science Connection
Continued from page 7
These food levels look like a
pyramid. The large base of the
pyramid represents the primary
consumers. The smallest number
of consumers is at the top.
At each level some energy is
lost. This is because each time there
is a transfer of energy from one
level to another, not all the energy
is transferred to the animals. Some
of the energy from the animal that
is eaten goes to the animal that is
eating it and some of the energy is
lost as body heat. Some energy is
lost from plants as they give off
heat and oxygen.
Primary consumers give off
heat energy, so there may be only
half of the original energy left for
secondary consumers. In turn, the
secondary consumers give off more
energy, so the tertiary consumers
receive the least amount.
Animals always depend on the
next level down on the pyramid for
food. If the producers (plants) were
to suddenly disappear, all the
animals on the rest of the pyramid
would die. If the next level down is
abundant, the animals will thrive.
In a lush tropical rainforest there
are plenty of plants. Many animals
are able to live there because of the
large amount of energy in the food
In a dry desert, there are few
plants, so there are some primary
and secondary consumers, but few
tertiary consumers.
To keep an ecosystem in
balance there needs to be many
plants, many primary consumers,
fewer secondary consumers, and
the fewest tertiary consumers. This
allows the system to have the most
energy at the bottom so that the
animals at the top will have enough
energy to live.
1. Go to these web sites to learn
more about the food pyramid:
Draw a blank pyramid and divide it into three levels - primary, secondary, and tertiary.
Do some research in books or
on the Internet to write examples of plants and animals that
are at each of these levels.
2. Create a story, song, poem,
or video that explains how the
food pyramid works.
Humans are at the top of the
food chain. We’re tertiary
Why is it important for
humans to be concerned about
what happens to all the levels
below us on the food pyramid?

World Biomes
Different Climates, Different Geographies
Jim Conrad, Naturalist,
The major biomes of the world are shown in colors.
Depending on the book you read or the web site you visit,
you may find different names for the biomes of the world.
Scientists and geographers don’t always agree on the names
of the biomes or where they begin and end..
What is important is that we understand how biomes and the
plants and animals that live in them differ from others around
the world.
For this article we used the biomes listed in Usborne’s
Science Encyclopedia. Some names on the map are different
from the names we use in this article.
The world is generally divided into areas that have the
similar kinds of climates and geographies. These separate
areas are called biomes. They have similar plants and
animals, similar makeup of soil, and are about same height
above sea level. They are named mainly by the kinds of
trees and bushes—the vegetation—that grow there. We
will explore eleven biomes in this article.
The land in northern Europe, Asia , America and
Greenland is cold, vast, and treeless. Six months of the
year the sun does not rise. Temperatures are around -30
degrees F. It is impossible to grow vegetation in the
permafrost subsoil. Polar bears, caribou, and grey wolves
live there.
Coniferous Forest
This is the largest biome of the world. Most of the wood
that is used in paper making comes from the pine trees in
Alaska, Canada, northern Europe and northern Asia. There
are other cone-producing trees, such as spruce, hemlock,
and fir, growing there. Another name for the biome is the
Taiga. Moose, the snowshoe rabbit, and the horned owl
live in this climate. The winters are very cold. Many of
the animals survive the winters by migrating or hibernating.
Tropical Rainforests
There are rainforests in the Amazon River area, Central
America, West Africa, Western India, Southeast Asia, and
Australia. There is abundant precipitation and year round
warmth. The amount of sunlight that plants get on three
levels of the forest is the limiting factor of plant life.
Precipitation is about 100 inches a year. Temperatures are
over 64 degrees F. Both animals and birds have bright
colors, sharp patterns, and loud voices and eat many large
fleshy fruits. Elephants, tigers, chimpanzees, king cobras,
toucans, and vampire bats live here.
Tropical Grasslands
This biome is located along the equator in Latin America,
Africa, Asia, and South America. There are 70 inches of
rainfall each year. More than 15 million species of plants
and animals thrive in this biome.
Continued on next page
March/April 2009
Geography Connection
Continued from page 10
Anteaters, jaguars, macaws, and parrots are only a few of
the animals. The lands of the tropical forests are becoming
endangered. People have cut and burned the trees for
firewood, for building materials, for making paper, and for
farming and grazing of animals.
Deciduous Forests
Trees that lose their leaves in winter grow here. In the fall
the leaves cover the ground and provide rich nutrients for
the fertile soil. This mild temperate zone stretches across
the eastern part of North America, the middle of Europe,
and eastern China All kinds of forests are filled with plant
and animal life. The bald eagle lives here along with the
black bear, deer, squirrels, rabbits, raccoons, woodpeckers,
and cardinals.
The ocean biome covers 80 percent of the earth. Most of
that is salt water. Algae, seaweed, and bacteria grow in the
water. Crabs, barnacles, clams, flounder, and mussels live
near the shore. Whales, swordfish, octopi, dolphins, and
tuna live farther out in the ocean. There are no insects in
the ocean. The biome is characterized by changing
amounts of light and temperature.
Polar Areas
The climate is very harsh. There are cold temperatures, to
5 degrees C, and high winds. There are no trees to provide
shade. Plants are a combination of algae and fungi called
lichens. Small floating plants (algae) in the ocean supply
food for any animals, fish, and whales in the waters. Seal
and penguins migrate here. Blue whales, the largest
creatures living on the planet, along with Minke whales and
Humpback whales, are found off the shores. They feed on

of the hot and dry deserts are the Arabian and the Sahara.
Two cold and dry deserts are the Gobi and the Antarctica
deserts. Little or no plant life, except cactuses, grows on
the deserts because there is no water. Snakes, lizards, some
frogs, and toads live there, along with the camel and the
emperor penguin.
Temperate Grasslands
Grasslands exist around desert areas. They are also hot and
dry. But, have enough rainfall to support the grasses and
some flowering plants. The grasses are home to large and
small herbivores. They are used for cattle grazing and
cereal crops. The land of this biome is also known as
prairies, veld, savannas, steppes and pampas. Prairie dogs,
giraffes, zebras, and lions live there.
This biome is found in the west coast of the United States,
the west coast of South America, and the Cape Town area
of Africa and central Australia. The winters are mild and
wet; the summers hot and dry. Densely growing evergreen
scrub oaks, plants with hard leaves, pines, and cork and
olive trees grow there. The flat plains, rocky hills, and
mountain slopes are home to small nocturnal animals,
chipmunks, coyotes, komodo dragons, and in Australia, red
kangaroos and wallabies.
Mountains are found on all the continents in two great
belts: The Circum-Pacific and the Alpine – Himalayan
chains or ranges. It is very cold and windy there. The land
is usually treeless; however, at lower elevations some
forests do exist. Mountain animals include the goat, the
puma and the yak.

What are March and April like in your ecosystem? We anxiously await spring after
Groundhog Day, February 2nd. The question we
always ask is…
1. Do a choral reading with different people reading
different stanzas.
2. Pick one stanza (one biome). Using the Internet
or books, find more information about that biome.
Draw or find a picture to show what the biome
looks like. Hold it up as you read the stanza of
the poem.
3. Take the part of a biome. Use creative dance or
movement to show (interpret) what the biome is
like. For example, you might move quite a bit if
you are the rainforest, but there may not be a lot
of movement in the polar region. Dance your part
as the stanza about your biome is read.
4. Make your own biome poem. If you are really
adventuresome, add music and sing it! You could
even make a music video of it.
5. Create an artwork such as a drawing or diorama
to show your biome.

Alaskan Wildlife Center
Saves Animals for Study
An Interview with Stephen Kroschel
Interviewer: David Cochran
G. Morgan
Steve Kroschel holds a rescued linx.
Last summer, on my trip to Alaska, I toured the Kroschel Films
Wildlife Center in Haines, Alaska. It is filled with many species of North
American wildlife. Meeting Stephen Kroschel and learning about the
animals there and their stories was an unforgettable experience. It was
great to get in touch with Steve again for this interview. I’m happy to
share this adventure and photographs with our Spigot community. DC
Kroschel Films Wildlife Center is a privately held collection of
animals that have been rescued from the wild. It has been around for
almost 40 years. Stephen Kroschel, the owner, was born and raised in
Minnesota on a farm where he cared for wild animals. He has always
liked wild creatures, and it makes him happy to see people enjoy the
wildlife he protects. He has made a lifelong commitment to wildlife and
education for the general public through his films and live presentations.

Ellen Swallow Richards
An Early Ecologist
by Susan Macdougall
Wikipedia Commons
Ellen Swallow Richards
The word ecology was
first used in Germany to
describe the household of
nature. Mrs. Richards
applied it to humans and
their environment.
Ellen Henrietta Swallow
Richards (1842 –1911) accomplished
amazing things in her lifetime. She
believed that a clean environment
was very important in our lives. She
created the word ―euthenics.‖ This
means the improvement of the
environment inside and outside the
In 1892, in a speech to a group of
scientists, Mrs. Richards discussed
ecology as the relationship of
organisms to their environment. With
this, she began the home ecology
movement which became known as
home economics. It showed the
importance of good nutrition, proper
clothing, physical fitness, sanitation,
and home management. In the late
1800s few women worked, and she
wanted women to know the
importance of having a good
environment in their homes.
Ellen Swallow (her maiden
name) became the first woman
admitted to a scientific school. She
was accepted as a special student to
the Massachusetts Institute of
Technology (MIT). As a student,
she studied thousands of water
samples from streams throughout
Massachusetts. This became one of
MIT’s most important projects. She
also did pollution research and told
people about the need for sewage
treatment plants.
She created a Women’s
Laboratory at MIT but wasn’t paid
for her work. She taught courses in
chemistry, mineralogy, and biology.
She was later given a paid faculty
position. 20
Mrs. Richards wrote the first
health-food cookbook and was very
active in public health issues. She
organized the first school lunch
programs to be sure children were
well fed. She set up model kitchens
to teach working class families how
to eat well and inexpensively. She
showed one of these sample kitchens
at the World's Columbian Expo in
Chicago in 1893. She also wrote
many books.
Ellen Swallow Richards believed
in education and opportunities for
women throughout her life. She was
a trail-blazer for women in helping
people in the late 1800s learn about
the importance of keeping a healthy

Are People Too
Timeline of Famous Ecologists
The word ―ecology‖ was first used
just a little over 100 years ago. Back
then, botanists (scientists who study
plant life) mainly described and
classified plant life in the environment.
However, Dr. Eugenius Warming
(1841 – 1924), a Danish botanist, in
his book Plantesamfund, completely
changed the study of botany. Writing
about communities of plants, he
invented the field of plant ecology.
Here are six scientists who have added
their findings to the growing science of
the ecosystem.
1913 Henry Cowles (1869 – 1939)
is considered the first American
ecologist. Always carrying his
notebook and camera, he carefully
observed the grasses, flowers, and
trees around Lake Michigan. He noted
the different kinds of soil, changes in
climate, weather, and lengths of time
for vegetation to germinate and grow.
In his published papers, Cowles noted
patterns of change in the natural plant
1927 Charles Elton (1900 – 1991), 1973
a British biologist, also held a degree
in zoology. He was one of the first to
study animals in their habitats. While
observing the relationship between
living creatures and their natural
environment, he discovered what he
called the food chain. Food for all
animals starts with plants and moves
up through lower animal life to
humans. The species at the bottom of
the food chain is always greater in
number than the species at the top. He
called this the pyramid of numbers.
1935 Arthur Tansley (1871 –
1955), a British botanist and
ecologist, introduced the concept
“ecosystem” as a basic unit of nature.
Before his work, scientists were
studying individual species. Tansley’s
work focused on habitats where the
environment as a whole, with both
living and non-living elements,
affected the life of all within.
George Evelyn Hutchinson
1916 Frederick Clements (1874 – 1957
(1903 – 1991), an English born
1945) made careful, detailed
observations of the plant growth in
grasslands as he drove his mule train
across Nebraska. He found changes in
the land brought on by nature
(tornadoes and fires), by humans (cart
tracks and plows), and by animals
(herds of cattle). In these bare spots,
new plants grew, died, and were
replaced by other kinds of vegetation.
He called this the succession of
American zoologist developed the
theory of the ecological niche. This is
a place that meets the needs for a
species to be able to tolerate the
physical environment, get energy and
nutrients, and avoid predators. These
are all measurable qualities. This is
also a way to compare niches of
several species. 21
Bob May ( 1936), an
Australian physicist, noted during the
1970s that acid rain was harming forest
and lakes. Overfishing was emptying
our lakes. May used mathematical
tools to make ecological forecasts
about natural resources. Using models
to predict the future, scientists can
now plan how to maintain forests,
lakes, and soils to sustain life and
avoid extinction.

Health Connection
Our Body,
Our Ecosystem
Our body is our ecosystem. Its many parts
interact with the environment so that we can live
healthy, active lives.
The human body reacts to what we put in it just as
a pond might react if a frog jumped into it. If the
pond has a lily pad for the frog to sit on, and some
dragonflies for the frog to eat, the pond is in balance.
It works well. If, however, it has pollutants like oil in
it, the pond will not be in balance and the frog, lily
pad, and the dragonfly will all eventually die.
Just like the pond, if we put things in our bodies
that are changed into energy and help us move and
think better, our system will be in balance. If,
however, we put toxins, or poisons, in our body, we
will unbalance our ecosystem.
Toxins that upset our ecosystem include drugs,
alcohol, and smoke from cigarettes. These are
foreign to our bodies and interfere with its normal
process of energy conversion. When smoke goes into
our lungs, the impurities in the smoke get trapped
there. We have trouble breathing and adding oxygen
to our circulatory system.
Drugs and alcohol cause our metabolism, the rate
at which we burn calories, to act unnaturally.
Alcohol slows metabolism down, while some drugs
rev it up temporarily. This upsets our natural process
of converting food to energy. Our body then can
experience weight gain, loss of energy, or even
Toxic substances can also affect our movement
and thinking. People who have too many drugs or
alcohol in their system become impaired. They can’t
think or act in a normal way. They sometimes act
dangerously and can even hurt themselves or others.
Our human ecosystem isn’t just affected by what
we eat, smoke, or drink. It is also affected by how we
think. Our brain controls how we think and behave.
If we get upset and feel stressed, we can get sick or
have less energy. We can even become very
unhappy. If we are thinking and feeling well, we
have a lot of good energy.
Ecosystems work best when all the parts support
each other. That’s also important for our body
ecosystem. It’s important to keep all our systems in
balance. If we eat healthy foods, exercise, avoid
toxins and germs, and keep in a happy frame of mind,
our ecosystem will be in balance. Staying physically
healthy and mentally happy helps us make the most
of our lives.
1. Make a list of all the foods you eat for three days.
Decide how good these foods are for you. Do they
give you energy and help you keep active or do they
have too much sugar, fat, or salt in them? Decide
whether you should change what you eat to keep your
ecosystem in balance.
2. Make a poster or slide show about how our bodies
are like an ecosystem.
3. Go to
fit_kid.html. Read the suggestions for keeping your
body healthy. Use the main points to do a survey of
at least 10 people. Which of these suggestions do
most of the 10 people follow? Which ones do they
follow least? What do you think these results show
us? Discuss this with others.

human ecosystem physically healthy, mentally
happy, and in balance? 22
