Science Checkpoint 4 Review

Students read a book about animals from Australia and recorded notes in a table. The animals listed eat eucalyptus leaves in tall trees.

How are the animals adapted for getting food?

• All three animals have fur that protect them from the bark of the eucalyptus trees.

• All three animals use their tails like a leg to climb up to the eucalyptus leaves.

• All three animals use their sharp claws to climb up to the eucalyptus leaves.

• None of the animals can climb a tree to get to the eucalyptus leaves they eat.

A class studied the life cycle of a frog and studied the life cycle of a bean plant. They compared the life cycles in a Venn Diagram.

Choose as many of the following steps which are part of the life cycles of all living things?

• All living things develop in a life cycle

• All living things hatch from eggs

• All living things die

• All living things form flowers
