Navanax
The Navanax is a sea slug and a part of the Mollusk phylum. It has
small, dash-like spots all over it and two orange lines going from one side,
to the middle, to the other side. They are at least 22 cm long. The Navanax
feeds on other sea slugs.

Island Fox
has been on
the Island for
4,000 years.
It is the

animal on
the Island.

Living Organisms
5
Great Blue Heron
• Great Blue Herons have
long legs for wading and a
long beck for fishing. It has
a wingspan of 167-201 cm
and is 115-138 cm tall. It is
found in open water and
wetlands in North and
Central America

Flora
7
Catalina Cherry Tree
• The Catalina Cherry Tree has
black edible cherries, but they
are all seed and skin (95%
pit). They thrive in sun and
need plenty of water. It also is
native to Catalina which
means it was not brought over
by the early settlers from the
main land.
Flora
8
Giant Kelp
• The Giant Kelp can grow
two to three feet per day. It
has air sacs which contain
a mixture of oxygen,
nitrogen, and carbon
dioxide to stay afloat so it
can gain access to the sun
for photosynthesis. It grips
onto a rock with its holdfast
which is one of the
strongest glue-like
substance in the natural
world. It is actually part of
the algae kingdom.
Flora
9
Toyon Tree
• The Toyon tree, also
known as the Christmas
berry, can grow 25 ft tall
and is a part of the rose
family. The berries are
edible but poisonous if
consumed in large
quantities. They usually get
confused with the Holly
tree because of its hollylike berries that stay red
through the winter.

Natural Phenomena

Erosion
•
Erosion is the process of breaking
down rocks with water. It will take
around ten thousand years for a
fist-sized rock to turn into sand. So
a way to tell how long a rock has
been on the shore is to look at its
size. You can tell if the rock has
been subject to erosion for a very
short time (large, jagged rocks),
has been occurring for a time
(medium, somewhat smoother
rocks) or has been occurring for a
very long time (sand-size, very
smooth pebbles).
Natural Phenomena
12
Low tide
Low tide is caused by the
gravitational pull from the moon
to the Earth. It happens twice
daily. When this happens, the
water levels drop in one area
but rise in another area far
away (when looking down on
the Earth it will be 90 degrees
both left and right). Also during
low tide, you will be able to see
more kelp because the kelp will
lay along the surface of the
ocean due to the lower water
level not being able to hold the
kelp straight up .
Natural Phenomena
13
Catalina Island
• Catalina Island is
considered an island of
California, but it wasn’t a
part of California that just
split off. It was formed by
an underwater volcano.
• Even though it is
surrounded by water,
Catalina Island is
considered a desert island.

Safety
• The student are following the
rules by not standing on the
benches. They are wearing
lifejackets so if they fall out
of the boat they will be able
to float. They are also
listening to the instructions.
They aren’t playing around
or talking with each other.
Science Attitudes
16
Bat Ray and Lunchbox
• Both instructors set good
examples by wearing hats to
protect their faces from the
sun. Lunchbox is wearing
sunglasses to protect his
eyes from the sun. They
also have their backpacks to
hold anything they may
need.

Correctly Prepared
• Colin has a thick wetsuit to
protect himself from the
cold water. He has googles
and a snorkel that fit him
well. He also has water
shoes to protect his feet
from cuts due to sharp
rocks on the beach.

Summary
• In Catalina we learned about fish, birds, plankton, whales and, most
importantly, ourselves. Within our sixth grade class, we formed new
friendships, strengthened old ones, faced some fears, and best of all, we
conquered those fears. This trip was fun and meaningful.
