A shadow happens when an object blocks the sun’s rays. Shadows are longer in the winter because of the angle of the sun.
Black or dark objects absorb light and heat. White or light objects reflect it. During the summer, you’ll stay cooler if you wear light clothing.
Some objects, such as glass, are transparent. Light can shine through them. Some light shines through translucent objects, such as a balloon or sheet of wax paper. Light cannot shine through opaque objects and you can’t see through them. Opaque objects, including a desk, bath towel or blanket, are solid.
