1. Baby Animals Who Do NOT Look Like Their Parents
Year 2 Science Unit Good to Grow Lesson 4

2. Frogs and Toads
Most baby animals in the natural world look like their parents when they are born. Some do not. One good example of this is a toad or frog.

3. Australias Native Amphibians
Frogs are vertebrates
(animals with backbones)
and are amphibians.
All Amphibians:
Have a three-chambered heart.
Breathe through their skin as well as their lungs.
Spend part (or all) of their life as a larval stage living in freshwater
Can survive for a period of time living in water or on land

4. Shelter Shelter in daytime during breeding periods.
This may be in hollows,
cracks and crevices in
rocks and logs, under leaf
litter, in sand or
gravel, or on the under-
sides of shady leaves

5. Safe Hiding Place
During non-breeding times and during droughts Some frogs burrow into leaf litter, soil or sand; others live in cracks, crevices and hollows in trees, logs and rocks. Some use camouflage – can you find this frog?

6. Food
Many frogs eat insects, spiders and other small invertebrates. Large frogs may eat small lizards, mice or small birds. Some may eat other frogs. While they are young, tadpoles usually eat algae and other aquatic plant matter.

7. Water for Breeding
Most frog species have particular water requirements.
Some tadpoles need shallow water, others deep water.
Some prefer still water and some running water.
Eggs may need to be attached to plants.
Eggs of some species float on the water in a kind of foam or froth.
There has to be sufficient water present long enough
for tadpoles to complete their development.

8. Frogs Need a Home
Some frogs burrow into leaf litter, soil or sand. Others live in cracks, crevices and hollows in trees, logs and rocks.

9. Other Animals Who Do Not Look Like Their Parents at Birth
Other animals and insects
who do not look like
their parents when they
are born include:
Flies
Ladybugs
Kangaroos and wallabies

10. Joeys
Kangaroos, wallabies spend the first 6 months of their lives developing from an embryo into an infant. They start their lives looking very different from their parents.
