This controls the pitch. Name what type of pitch a short ____ makes and what a long _____ makes.
Wavelength. short wavelength --> high pitch, long wavelength --> low pitch
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 some experiments that helped you understand waves.
SIM, Rope, slinky, coins, binary codes, sending images, Music time with the teachers

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
