Frog Pond Life Cycle Model
Materials: non-waxed paper plates, crayons (no shades of
blue), small sponges, watered down blue tempera paint, small containers to hold
the paint, small “flippy frogs” – 1 per child
Pass out the crayons and the plates.
Explain that frogs begin their life in the water and that
baby frogs come from eggs. The eggs are
laid in a group.
Animals that begin their life in the water and then live on land
are called amphibians.
Baby frogs are called tadpoles. They don’t look like their parents.
Ask the children to take a dark crayon and draw frog eggs in
Then have them draw three tadpoles. Give one frog hind legs. Then give one frog hind
and front legs.
Talk about the things that a tadpole would need to survive
in its habitat.
Tadpoles eat plants.
They are vegetarians. The
children will need to draw some plants.
As a tadpole gets older, it will begin to prey on insects,
worms, and even small fish.
Ask the children to use their crayons to make a log for the
adult frog to sit on to warm itself in the sun.
Amphibians are ectotherms. Their
body temperature is the same as the outside air.
Then have them draw some bugs in the water. Adult frogs catch insects with their sticky
Help the children dip the ends of the small sponges into the
paint and paint over their “pond." (The sponge needs to be only slightly damp
with the paint.)
These will dry quickly.
Give each child a frog and let them see if they can get it
into their “pond."
