What is one example of a pattern in sound?
Up and down (waveforms) or side to side (colliding particles)
300

300
Just like how a baby dolphin searches for its mother, try searching for Waldo! Go! 
You found him!
400
What kinds of patterns do dolphins use to communicate? Make your best dolphin sound!
Signature whistles, patterns of pitch changes
400
A short ____ makes a low pitch and a long _____ makes a high pitch. Show us your dance moves!
long wavelength ->low pitch
short wavelength -> high pitch
(Awesome dance moves)
400
What were some ways that you communicated using code with your classmates?
Code communicator SIM, Drawing on the grids to encode and decode using binary code, sending a image
400
Name 2 experiments that helped you understand how sound waves and patterns.
SIM, rope model, slinky model, chips model, binary codes, sending images, music, etc.
500
Using scientific language, explain how sound is different.
Sounds have different patterns of wavelength and ampitude. This can affect the volume, pitch, and even the sounds that the dolphins make.
500
Explain the difference between encoding and decoding.
Encoding -> translating something familiar to a code
Decoding -> translating code to something familiar
500
Why is binary code useful for communicating across distances?
Binary code is simple, digital devices use binary code to send and receive information fast.
