Review What did we talk about yesterday?

_________, ___________ and __________ are animals that are capable of flight. Lots of other animals are capable of ___________, but the above three animals are the only ones that can truly fly. The ___________ of these animals is quite different from animals who don’t fly. For example, the _________ of birds are hollow, they only have one _______ and they have very strong ______ muscles to move their wings and produce _______.

Birds, insects and bats are animals that are capable of flight Birds, insects and bats are animals that are capable of flight. Lots of other animals are capable of ___________, but the above three animals are the only ones that can truly fly. The ___________ of these animals is quite different from animals who don’t fly. For example, the _________ of birds are hollow, they only have one _______ and they have very strong ______ muscles to move their wings and produce _______. In order to have enough ________ to fly, birds have a very high ________. That means they have a high ______ rate, take in a lot of air when they ________, and food passes through their _________ system very quickly!

Birds, insects and bats are animals that are capable of flight Birds, insects and bats are animals that are capable of flight. Lots of other animals are capable of gliding, but the above three animals are the only ones that can truly fly. The ___________ of these animals is quite different from animals who don’t fly. For example, the _________ of birds are hollow, they only have one _______ and they have very strong ______ muscles to move their wings and produce _______.

Birds, insects and bats are animals that are capable of flight Birds, insects and bats are animals that are capable of flight. Lots of other animals are capable of gliding, but the above three animals are the only ones that can truly fly. The anatomy of these animals is quite different from animals who don’t fly. For example, the _________ of birds are hollow, they only have one _______ and they have very strong ______ muscles to move their wings and produce _______. In order to have enough energy to fly, birds have a very high __________. That means they have a high_______ rate, take in a lot of air when they _______ and food passes through their _______ system very quickly!

Birds, insects and bats are animals that are capable of flight Birds, insects and bats are animals that are capable of flight. Lots of other animals are capable of gliding, but the above three animals are the only ones that can truly fly. The anatomy of these animals is quite different from animals who don’t fly. For example, the bones of birds are hollow, they only have one ovary and they have very strong chest muscles to move their wings and produce lift. In order to have enough energy to fly, birds have a very high metabolism. That means they have a high heart rate, take in a lot of air when they breathe, and food passes through their digestive system very quickly!
