153 Facts

101. Sound is sent from the radio station through the air to your radio by means of electromagnetic waves. News, music, Bible teaching, baseball games, plays,
advertisements- these sounds are all converted into electromagnetic waves (radio waves) before they reach your radio and your ears.
102. At the radio station, the announcer speaks into a microphone. The microphone changes the sound of his voice into an electrical signal. This signal is weak
and can't travel very far, so it's sent to a transmitter. The transmitter mixes the signal with some strong radio signals called carrier waves. These waves are
then sent out through a special antenna at the speed of light! They reach the antenna of your radio. Your antenna "catches" the signal, and the radio's
amplifier strengthens the signal and sends it to the speakers. The speakers vibrate, and your ears pick up the vibrations and your brain translates them into
the voice of the radio announcer back at the station. When you consider all the places the announcer's voice travels
103. Every radio station has its own frequency. When you turn the tuning knob on your radio, you are choosing which frequency you want your antenna to "catch."
104. Mountain lions are known by more than 100 names, including panther, catamount, cougar, painter and puma. It's scientific name is Felis concolor, which
means "cat of one color." At one time, mountain lions were very common!
105. The large cats of the world are divided into two groups- those that roar, like tigers and African lions, and those that purr. Mountain lions purr, hiss,
scream, and snarl, but they cannot roar.
106. They can jump a distance of 30 feet, and jump as high as 15 feet. It would take quite a fence to keep a mountain lion out!
107. Their favorite food is deer, but they'll eat other critters as well. They hunt alone, not in packs like wolves. They sneak up on their prey just like a
house cat sneaks up on a bird or toy- one slow step at a time. A lion can eat ten pounds of meat at one time! That's equivalent to 40 quarter-pounder
hamburgers!
108. Queen ants can live to be 30 years old
109. Dragonflies can flap their wings 28 times per second and they can fly up to 60 miles per hour
110. As fast as dragonflies can flap their wings, bees are even faster... they can flap their wings 435 times per second
