Look through the pinhole at the glowing lamp. The print on the outside of the bulb can be read when looking through the pinhole. The card shuts out most of the light from the bulb, allowing the print to be visible. During a solar eclipse, the Moon blocks the glaring light from the Sun, allowing the less intense glowing outer surface, or corona, to be studied. Explanation Birds have different ways of flying depending on the shape of their wings.
Broad wings give a bird a good lift for slow flight or for rapid takeoff.
Tails enable birds to maneuver around. Some birds, like eagles, have wide-spread feathers and long wings, which help them glide and soar in the air for hours. Pheasants have short, broad wings, enabling them to make quick takeoffs and steep climbs. Procedure Put the object on the sheet of paper in the sun.
