You have brought us great understanding about sound and how Earth communications happen! Because...
You used models, creative simulations, plays and displays to show your findings.
You were able to search using Earth's communications systems and get detailed pictures, ideas and conceps of Earth's history of communications.
You used clear, detailed and correct explanations on concepts of sound, electricity and invention processes.
You were able to put it all together to connect how communications of different kinds came to be, why they were invented and how they affect humans.
You attempted with success to develop a new communication invention.
You have some very good ideas from the way communications happen on Earth, Because...
You used models, simulations or displays to show your findings.
You were able to search using Earth's communications systems to get some good ideas about their history.
You used adequate explanations, so we get an idea of what sound, electricity or inventions are all about.
You were able to show how some of the ideas connect to others.
You attempted to develop a new communication invention, and have at least the "blue-print" or plan for it.
Your explanations gave us some idea of how communications on Earth, Because...
You used at least two different ways to show your findings.
You used Earth's communications systems with some help
Your explanations about sound, electricity and inventions were limited for our purposes.
You made some connection between ideas, but we couldn't quite tell how they releated to each other.
Your attempt to develop a new communication invention is shared, but there are no records to show it.
Your explanations showed some of the experiences you had, but the information on what communications is all about was limited because...
You used only one way to show your findings.
You needed much assistance from the home planet to use their communications systems.
Ideas about sound or electricity or invention were unclear.
No connections were made to show how one idea relates to another.
There was no attempt to develop a new communication invention.
