Frogs lay thousands of jelly-covered eggs that do not have shells. This jelly protects the eggs from being eaten by creatures in the water. Frogs lay their eggs in water or wet places so that the eggs don't dry up or die. The floating clump of eggs is called a frog spawn

Slide 4/Stage 2: Answers

The embryos develop in the eggs and grow until they look like small tadpoles, or frog babies.

The tadpoles grow until they are big enough to break free.

This can take from three days to three weeks. Tadpoles have a head, tail and body.

They breathe by getting air from the water through their gills.

They eat algae as they swim. As tadpoles grow, their gills shrink and a flap of skin grows over them. They also develop tiny teeth and a jaw.

Slide 5/Stage 3: Answers

After the tadpoles are one month old, a bulge appears at the base of their tail.

This is where their hind legs are going to grow. They also grow lungs for breathing.
