Transcript Creating and Implementing an Absorb Type Activity

Introduction
Frogs spend their lives near water because they must
return to the water to lay their eggs. Frogs eggs are called
frog spawn. Frog spawn is laid in the water. When the frog
spawn hatches into tadpoles, the tadpoles breathe with
gills and swim using a tail. As they grow the tadpoles begin
to lose their tail. They also grow legs and develop lungs for
breathing air. Frogs eat insects , catching them with their
long, sticky tongue. They also eat small fish and worms. In
the winter frogs hibernate, that means they sleep very
deeply. You might find them hibernating under stones or
buried in mud or hiding in the bottom of ponds where they
breathe by absorbing oxygen through their skin.

Life cycle of a frog: web-footed amphibian which
lives near lakes and ponds. Moves by swimming and
jumping.
Adult frog: mature frog.
Tadpole frog: phase of the life cycle of a frog
between tadpole and adult.
Start of pulmonary respiration: the beginning of
respiration with the lungs.
Front legs break through: beginning of the
development of the rear limbs.
Tadpode: frog larva.
Embryo: frog still in the egg.
Eggs: cell resulting from a fertilized ova which
contains the frog embryo.
The Frog Life Cycle Visual Diagram begins
as tadpoles hatch from tiny eggs that are
laid in masses in the water. The gillbreathing tadpole swims in the water. It
eventually sprouts legs and absorbs its tail,
becoming a froglet and then an adult. The
adult breathes air and has no tail. After
mating, the female lays eggs and the
cycle begins again.

Frogs are amphibians because they start their frog life cycle as eggs in the
water and then turn into tadpoles, which have gills and also live in the water.
It isn’t until a tadpole turns into a frog that it can live outside of the water, but
it will still need to get in the water to drink and to cool off.
Frogs don’t actually drink water with their mouths; they drink it through their
skin. A frog’s skin absorbs water when it is in the water so its body gets all of
the hydration that it needs that way and the frog doesn’t need to drink with
its mouth.
Frogs are cold blooded. That means that the body temperature of a frog is
the same on the inside as it is on the outside. That is why frogs need to be
near water so that they can jump in and cool off on hot days.
Not all frogs are green. There are hundreds of species of frogs and each one
looks different. Some frogs are red and some are yellow and some are
brown. All of the different species of frogs have different patterns on their
skin, too.
A frog won’t turn into a prince, no matter how many times you kiss him!

egg - Tiny frog eggs are laid in masses in the
water by a female frog. The eggs hatch into
tadpoles.
tadpole - (also called the polliwog) This stage
hatches from the egg. The tadpole spends its
time swimming in the water, eating and
growing. Tadpoles breathe using gills and have
a tail.
tadpole with legs - In this stage the tadpole
sprouts legs (and then arms), has a longer
body, and has a more distinct head. It still
breathes using gills and has a tail.
froglet - In this stage, the almost mature frog
breathes with lungs and still has some of its tail.
adult - The adult frog breathes with lungs and
has no tail (it has been absorbed by the body).
The above illustrations is an example of the
type of assessment that may be used to
determine the gained knowledge from the
lesson by having the learners connect the
appropriate vocabulary word using the
written explanation of the life cycle
process.
