FA Honors Biology
Solar Bag 9-25-09
If you see a diurnal raptor on an autumn day, you will hardly ever see it flap its wings. Each time a bird flaps its wings, it expends a tiny amount of energy...energy that needs to be saved for the long journey south. By riding and soaring on the thermals, birds of prey conserve their energy for the hundreds or thousands of miles that lay ahead of them.
On Friday morning, September 25, the Honors Bio classes went outside to fly the giant Solar Bag. The air inside the black bag heats quickly in the sun and the bag rises rapidly into the sky. While we had great fun chasing the bag around the soccer field, we also saw a very important lesson. High in the sky overhead we noticed an adult bald eagle soaring with wings spread wide flying from the north to the south.
