How It Works
Each deck consists of 30 pairs of cards dealing with Sound concepts. Players take turns asking each other for a
card to complete their pair. The winner is the first person who collects the most number of pairs.
How to Play
1. Deal seven cards to each player. Put the rest face down to create a draw pile.
2. Each player looks for pairs in his hand. In turn, players read their pairs out loud and put them
face up on the table in front of them.
3. Play begins as Player 1 asks any other player for a card he/she needs to make a pair. For instance, "Michael,
do you have Something must vibrate to have sound?
4. If Michael has that card, it is given to Player 1. Player 1 puts the pair face up on the table and picks
another person to ask. Player 1 continues until the person he asks does not have the card asked for.
5. If a player does NOT have the card asked for, he says SILENCE. Player 1 picks a card from the draw pile.
If the card matches his request, he goes again. If not, play goes to the next person. (If a different match is
made, it is read, put down, and play goes to the next person).
6. Play continues until someone is out of cards.
7. The winner is the person with the most pairs.

Silence Pairs Sound is a form of energy. Something must vibrate to have sound. Sound travels fastest through solids. Sound travels slowest through air. Sound travels through a gas slowest, liquid
faster, and solid fastest. Sound cannot travel through a vacuum such
as outer space. Sound waves. Crest, trough Wavelength, amplitude Compression, rarefaction The faster the vibration, the higher the frequency. Pitch is the highness or lowness of a sound. The number of vibrations per second is called
frequency. Hertz (Hz) is the unit to measure frequency. Volume is how loud or soft a sound is. Decibel (dB) is the unit to measure volume. Sonar is used by ships to map the ocean floor. Radar is used by ships, planes, police, and
the weather service. A reflected sound wave is called an echo. Bats and dolphins use echolocation. The hole in the guitar lets sound resonate. The further you are from the sound, the harder
it is to hear. The closer you are to the sound, the louder
it is. Speech happens when our vocal cords vibrate. Bells, whistles, and sirens capture our attention
for warning or safety. High pitch, high frequency Low pitch, low frequency Long or wide = low pitch. Short or thin = high pitch To make a rubber band’s pitch higher,
stretch it. Long column of air = low pitch. Short column of air = high pitch.
