LIFE CYCLE
In spring there are frog
eggs in pounds. Frog
spawn has 100s eggs
clumped together. Male
grass frogs guard their
eggs. The eggs are in a
nest that is hard foam on
the outside and wet
inside. The egg is a ball
that is clear jelly. It has a
dark center.
GROWING
Tadpoles grow inside
the eggs. They are tiny.
At first they are a speck
and after a few days
they grow heads and
tail. When they are
bigger they wiggle out.
Then the tadpoles eat
their jelly and swim
away.
TADPOLES
Tadpoles use their
gills to help
breathe under
water.
In a few more
weeks their tails
shrink and shrink.
GETTING BIGGER
Tadpoles eat and grow that’s
its main job. They get a little
bigger every day. Soon their
two front legs grow. They
have gills to breathe under
water. After a few weeks the
tadpoles have two hind legs
to move its body. After they
grow lungs they swim up and
put their head out of the water
so they can breaths air. Frogs
have strong legs and webbed
feet to help it swim.
TADPOLE DIET
As it grows lungs grow
and the gills shrink.
Tadpoles have hard
mouth and scrape soft
plants of off rock and
pebbles.
Tadpole starts to eat
small bugs. The tadpole
changed into a small
frog then it leaves the
pond.
