Life Cycle
This is the first of a frog's life when it hatches from an egg.
Tadpole
Frogs often live near this because they need water to lay eggs.
Water (pond, marsh, lake, stream)
Many frogs eat small animals like these winged insects.
Flies (or mosquitoes, moths)
Many frogs make this sound to talk to other frogs.
Croak (or ribbit — acceptable)
The word for a baby frog that lives in water is _____.
Tadpole
Tadpoles live in water and breathe with these.
Gills
Frogs have sticky pads on their toes to help them do this.
Climb or stick to surfaces (answers: climb trees, stick to leaves) — acceptable: climb or grip branches.
Frogs catch food with this long, sticky body part.
Tongue
Some frogs can jump very far because of these strong muscles.
Leg muscles (strong back legs)
The word for the outer covering of a frog that helps protect and sometimes breathe is _____.
Skin
As tadpoles grow, they develop two of these before their legs appear.
Hind legs (or front legs — acceptable answer: hind legs first then front legs)
Some frogs change color to match their surroundings. This is called ____.
Camouflage
Name one animal that might eat a frog.
Examples: birds, snakes, fish, raccoons
This kind of frog is very small — sometimes smaller than a paperclip. (Hint: two-word answer, common name)
Glass frog (or "miniature frog" like the Paedophryne amauensis — accept "glass frog" or "tree frog" depending on context)
The name for the stage when a tadpole grows legs and lungs is _____.
Metamorphosis
This is the process when a tadpole slowly becomes an adult frog.
Metamorphosis
Frogs have strong back legs to help them do this important movement.
Jump or hop
Frogs are called ____ because they eat mainly other animals (not plants).
Carnivores
Certain frogs have skin that makes them taste bad to predators. This is a kind of ____ defense.
Chemical (or chemical/poison) defense
A word that means "an animal that eats plants and animals" is _____.
Omnivore (if including plants) or Carnivore (if diet is mainly animals) — expected answer: carnivore for frogs
Put these life stages in the correct order: adult frog, tadpole, froglet, egg.
Correct order: egg → tadpole → froglet → adult frog
Name two different habitats where frogs can live (one must be a freshwater place).
Examples: freshwater ponds, streams, wetlands, rainforests (any two, one freshwater)
Explain why tadpoles usually eat different foods than adult frogs.
Tadpoles often eat algae and plants while adults eat insects and small animals — because their mouthparts and gills change as they grow.
Explain why frogs are important for scientists studying the environment (one or two short reasons).
Frogs are indicators of environmental health because they have sensitive skin and live in water and on land; declines can signal pollution or habitat problems.
Define "camouflage" in one sentence and give a frog example.
Camouflage means an animal's color or pattern helps it hide in its environment. Example: a green tree frog blends in with leaves.
