Part B: Fill in the Blank
Write the missing word or number on each line.
1. A frog is an amphibian.
A frog starts life in water as a tadpole and later lives on land too, so it belongs in the amphibian group.
2. Snakes are reptiles.
Snakes have dry, scaly skin and crawl on the ground without legs, which puts them in the reptiles group with lizards and turtles.
3. Birds use wings to fly.
Wings flap up and down to lift a bird off the ground, which is exactly what they let a bird do: fly.
4. A fish breathes with gills.
Underneath the slits on the side of a fish are gills, the special body parts that pull oxygen out of the water so the fish can breathe.

Read each statement. Circle True or False.
1. A turtle is a reptile.
True False
True. Turtles have dry, scaly skin and lay eggs on land, which are signs of a reptile.

3. Mammals feed milk to their babies.

True. A special trait of mammals is that mother mammals make milk to feed their babies.
