Vocabulary!
Mollusk
Soft, underwater
invertebrate
without legs that
have shells for
protection.
Gills:
An organ used for
breathing
underwater in sea
creatures
Exoskeleton
A hard covering
on the outer body
of a sea creature
like a shell
Fins:
Wing-like organs
on some creatures
used for
swimming.
Tentacles:
The arms on some
under water
creatures used
for grabbing
objects and for
moving.
Scales:
The thin, flat
plates that
overlap and cover
and protect the
skin of fish and
reptiles.
Day one:
Display a chart all
about turtles.
Assess children’s prior
knowledge of turtles.
Gather the basic
information about
turtles.
Facts about turtles:
Sea turtles are
reptiles. They are cold
blooded. They cannot
survive in ocean water
that is too cold. They
migrate to warmer
waters when
temperatures drop.
Facts about turtles:
Sea turtles have four
flippers. They have sharp
jaws to tear food apart.
They eat seaweed, crabs
and fish. Their babies
hatch from eggs. Every
year the female turtle
climbs onto the beach.
They use their front
flippers to dig nests and
can lay up to 100 eggs.
After laying their eggs
they cover them with sand
and go back to sea.

3. Baby turtle
Once the children have
learned about the life
cycle and know it,
Construct the following
in art:
The children complete
the life cycle onto a 3d
shell template to make
a turtle in art.
Once the children have
copied the life cycle on
to the shell, glue it on to
the body of the turtle.
Day
Two.
Day two: vocabulary
check:
Write the new
vocabulary from day 1
onto lollipop sticks.
Have the matching
definitions printed.
Each child pulls a stick.
The teacher will then
read a definition and
the child must say if it
is the correct
definition.
If it is not, the child is
out!
Experiment/Octopus
Investigation:
Explore how octopus
shoot ink and why, how
does it protect them?
You will need:
Toy octopus
Plastic see through cup
Red ink/food dye,paint
dropper
Water
Experiment/Octopus
Investigation:
The children will observe the toy
octopus at the bottom of the
glass of water. We will explore
how we can see the octopus.
We will discuss why octopus
shoot ink at predators.
The teacher will drop some
ink/paint into the water.
What happens?
We will explore how we cannot
see the octopus when the ink is
in the water, like in real life it
stops the predators from seeing
the octopus.
Let’s think!
HOW do octopus stay safe from
predators?
Draw a picture of your
experiment:
Draw a picture of what
happened after you put the dye
in:
Record what this experiment
tells you about octopus and how
they protect themselves:
Mammals
:
Dolphins are mammals.
As all mammals, dolphins
nurse their young.
2. Dolphins can swim up
to 260 m. below the
surface of the ocean.
However they are mainly
shallow divers as they
need to reach the
surface to breathe.
3. Dolphins can stay up to
15 minutes under water.
Mammals
:
.
4. Dolphins use a technique
called echolocation. This
technique uses the same
principles of a radar, and it is
used to find food and navigate.
5. Dolphins are social beings.
Dolphins live in groups and
cooperate among each other for
activities like getting food and
calf-raising.
Can have are
:
Dolphin Ears Experiment
You will need:
A cup
Water
Metal spoons
Plastic bottle( end cut off)
Teacher will explain echolocation to
the children and how dolphins use
this to hear and communicate.
Teacher bangs two spoons together
and ask children what they hear.
Then fill a large bucket with water
and cut off the bottom of the bottle.
Children take turns to bang their
spoons together under water and
listen with the bottle to the sound.
This is echolocation!
Dolphin Ears Experiment
What is
echolocation?
Echolocation is
how dolphins
communicate and
find food and
objects in the
ocean.
Dolphin Ears Experiment
With your partner,
bang the two spoons
together under
water, then place
the cut off end of
the plastic bottle in
the water and listen
through the top of
the bottle. What do
you hear?
Record your experiment.
Questions and thoughts...
Seals
Seals are ocean
mammals who live
along the seashore.
They hunt for food
in the water. They
eat fish, squid, crabs
and squid. They
have big round eyes
to help them see
under water. Their
flippers make them
fast swimmers.
They move very
quickly in the water
and dive to get their
prey. They are very
slow on land and flop
on their bellies to get
around. They have
blubber and fur to
keep them warm.
Sharks and polar
bears are predators
of the seal. Baby seals
are called pups.
There are 33 types
of seal.
Seals can stay
under water for 30
minutes before
surfacing for air.
