2Fold two of the corners toward the center. Use the coin to crease the edges.
3Fold the wings back over the folded corners to create the glider shape.
4Have an adult help you poke a hole at the edge of the fold under the wing (see video).
5Insert the wooden skewer through the hole and tape it down to create support for the wings.
6Send your glider on a test flight.
7Try replacing the skewer with straws which are lighter and hollow, like bird bones.
8Try another test flight.
9Also, you might try changing the shape of the wings to make them even narrower.
10Try adding a tail. Birds use their tails to help them control their flight.
11Cut a triangular piece of construction paper, insert it into the back of the fold and tape in place.
12Test the glider again.
13Try other modifications based on bird structures - this activity is all about designing your own & testing it!
How It Works
Using the structures of living things to help inspire engineering designs is called biomimicry. Birds and other living things have structures that serve a specific function. When humans need to solve similar problems they can turn to animals and plants for answers. In engineering, we often build and test designs over and over. It improves each time!

In this lesson, we learn that:
All plants & animals have structures that help them survive.
Each structure has a specific function.
Animal structures may appear similar or different depending on where they live.
