Lesson 8 Page 2
Observe: Build a Bird
Look at these two birds:
Birds have specialized structures and behaviours that enable them to counteract gravity and drag, so they can take to the air. The unique shape and structure of their wings allows them to have both lift and thrust.
Although they have many of the same adaptations for flight, you can see that there are also significant differences. The hummingbird is a tiny flying machine. It has wings that can flap up to 80 times per second to enable it to hover in mid-air while feeding. In stark contrast is the 11-foot wingspan of the albatross that can glide for hours without flapping its wings even once.
Just as there are many types of flying machines, there are also many types of birds. Each one is designed uniquely to do the type of flying that will help it survive. There are differences in size, shape, and even how they use their wings. In this activity, you will consider some bird “designs” that work best for various types of flying.
