Field Trip: Cathance River Education Alliance, Topsham Maine
http://creamaine.org/
Sophie’s Blog: Tell us about the walk we took on Friday and
what we did, saw, and learned. Write 20 good sentences.
This afternoon, this afternoon was a special afternoon. It
was a warm Friday afternoon in late summer, and we went on a walk and learned
all about ecosystems (and mushrooms). Today we decided to go on a nature walk
at CREA. CREA stands for Cathance River Education alliance. We started off
walking on the Heath trail and we saw a small vernal pool and we sat down and
talked about its ecosystem. We saw tons of frogs including a super huge one. We
then kept walking and saw some liken, Mom told me what liken was and we kept
looking for different types of it. We walked in to a big vernal pool with a
dock were we saw people, we walked over and they asked us if we would like to
set free a turtle. We said yes, so the man brought out the turtle and let us
hold it. We set it off into the vernal pool and it went and hid from us. We
looked at the ecosystem for the big vernal pool and the lady was impressed with
us. So she invited us in to the ecology center and we learned more about liken.
We left the ecology center and went back on the Heath trail home. Mom told me
all about mushrooms and we probably saw and touched 50 different mushrooms.
Like I said it was a special afternoon!
Mushy
Ugly
Soft
Hard
Rocky
Obese
Optimistic
Muggy
Never eat mushrooms,
Or you’ll have to use the
flush-room!
Mushrooms can be brown, Mushrooms
can be yella, I hope I don’t get Salmonella
6 x 6 written by Sophie using this book: Earth-Shaking Science Projects About Planet
Earth by Robert Gardener
Vocabulary
1. Evidence: That
which tends to prove or disprove something; ground for belief
2. Pangea: The hypothetical landmass that existed when all
continents were joined about 300 million years ago
3. Plates: Parts of Earth’s crust that can move
4. Volcanoes: A vent in the Earth’s crust which lava, steam,
ashes, ect., are expelled , either continuously or at irregular intervals
5. Mantle: the portion of the earth, about 1800 miles (2900
km) thick, between the crust and the core
6. Earthquakes: a series of vibrations induced in the
earth's crust by the abrupt rupture and rebound of rocks in which elastic
strain has been slowly accumulating
Sentences
1. When people first started to think the Earth was round
they needed more evidence so Aristotle took a sphere and a lantern in a dark
room and proved that a sphere only made a round shadow, than during an eclipse
the Earth made a round shadow on the moon proving the Earth’s sphere shape.
2. Pangea was a
continent that existed a long time ago when all present continents were joined.
3. Plates are parts of Earth’s crust that can move and form
mountains and hills.
4. A volcano is an opening in Earth’s crust that allows
magma to reach earth’s surface.
5. The mantle is the layer of heavy rocks under Earth’s
crust.
6. An Earthquake is caused by the movements of plates; I bet
there were a lot of Earth quakes back when the continents were forming the
mountains and hills.
*Sophie, name and describe the 3 experiments in the book you
want to do and explain why?
1. Other Evidence for a round Earth, I want to do this
experiment because I think it sounds interesting to pretend to be Aristotle and
prove the Earth is round
2. Earths moving continents, I want do this experiment
because I want to see how we got our continents and everything
3. Earthquakes, I want to do this experiment because it
teaches you how to build buildings to resist earthquakes, Lily might need this
information in the future
Details/ Facts
1. Mount St. Helens, in the state of Washington, erupted
violently in 1980
2. An earthquake in 1989 damaged buildings in San Francisco,
California
3. Once there was a fence built across the San Andreas fault
in California. It was straight when built but when the land moved part of the
fence went with it
4. The Great Rift Valley in Eastern Africa marks a boundary
between two of Earth’s plates
5. When Australia became a separate continent, its mammals
were mostly marsupials
6. Earth is nicknamed a “beautiful blue marble floating in
space”
Questions
1. What is lava? A: Magma that has flowed on to the Earth’s
surface
2. How do you build buildings to resist earthquakes? A: You
put building of the same height at different distances from the epicenter
3. How do mountains form? A: When two plates of land come
together they can form a mountain
4. Which two continents do geologists and biologists think
were the first to separate? A: South America and Africa
5. Who is Aristotle? A: The man that said only a sphere can
make a round shadow which helped us discover the Earth’s shape
6. What are the layers of the Earth? A:crust, upper mantle,
mantle, outer core, inner core, core
Math
*Look back through the book and give me 6 examples in the
experiments where you use math
1. Other evidence for a round earth: you use math in this
experiment because you have to use geometry to see how the Earth is round
2. Three layers of the Earth: you use math for this
experiment because you have to measure with measuring cups how much water you
put in
3. Earths moving continents: you use math for this experiment
when you trace the continents to see the angles of the continents
4. Other plate movements: You use math for this experiment
when you see how far away the plates need to be from each other
5. Volcanoes: You use math in this experiment because you
need to see how much baking soda you have to use to make the “lava” come out
6. Inside Earth: You
use math to see how the mantle and the core are not the same thing
Current Events
*Find currents events about the Earth (earthquakes,
volcanoes, tsunamis, etc.) Write the headline, read at least the first 3
paragraphs, and copy link.

Ecosystem Observation Worksheet Front Pond
Date: 09/19/11 Season:
Fall
Time of observation: 4:00 Duration
of observation: 20 mins
1. List
three details or parts of the ecosystem you are observing:
Waterfall: faster than normal, fish, rocks,
algae in whirlpool at top and on rocks
Cattail: starting to fall, changing color,
some strands in the water
Socks (fish): skinny, bog orange bump over
head, still and deep, interacting with other fish, hid under rock
2. What
did you notice or observe?
The waterfall gives the fish oxygen, the
fish eat the cattail, the waterfall gives clean water to the cattail, the fish
eat the algae off the pump for the waterfall and the cattail attracts the algae
from the pump to make the waterfall faster
3. What
elements (weather, temperature, light, etc.) affected the ecosystem during your
observation?
Shade on pond, cool temperature
outside, cold water temperature, slight wind, sun the distance
4. What
things changed since the last time you observed the ecosystem?
Since summer: the
fish were skinnier, the waterfall was faster (less algae), the plants sere
small, the water was warmer, and there was a lot less algae on the rocks
5. What
changes do you expect to happen to the ecosystem before your next observation?
The water will be even colder, the plants
will be more titled and brown, and the fish will be deeper and slower
6. On
back, draw part of the ecosystem (can be specific detail, food web, metamorphosis
chart, picture):
