Squirrel Gymnastics (Quicktime movie, 3.6mb)

Watch this squirrel scamper around, track its movements, and describe its actions. Here's a tip to help you out: did you know that the left and right arrow keys will backup or advance a Quicktime movie one frame at a time? Use this feature to slo-mo your way through the squirrel's gymnastics.

Gliding gull (Quicktime movie, 504kb)

Gliding flight in birds
Ever notice how some birds hold their wings out flat when they glide while others have their wings up in a "V"? Have a look at the gull movie. What do you notice about the gull's wing position?

You can make a paper bird from a 5" x 8" index card (or other heavy paper) to test the effect on gliding flight of wing position and the curvature of the wing itself. Gliding flight means that you hold the paper bird by its tail and let it drop (rather that throw it). See the patterns. Adding weights (staples or paper clips) to the body section may improve the flight.

Pigeons, crows, starlings, hawks and gulls are frequent gliders. Use a mini-journal to record your observations of these birds in gliding flight. Draw the position of the wings. Take note of the wind speed and direction. Does the bird glide with the wind or against it? If you see a bird that uses several different wing positions, try to figure out what it might be responding to.
