Ring! Ring! Ring! Ring!

The Key Concepts for our current inquiry into How the World Works are:

CHANGE-How is it changing?
FUNCTION-How does it work?

This afternoon we used the 'telephone' invention as a main focus for developing our questions.

CHANGE
"How has the telephone changed over time?"

"How has the weight of the telephone changed?"

"Why did the telephone change over time?"

"How has the size of the telephone changed?"

FUNCTION
"How does the telephone work?"

"What pieces are inside a telephone?"

"How does a mobile phone track another phone?"

"How does a mobile phone send messages and mail?"

To help us answer these questions we used our brain, books and the internet.
We are hoping some experts can help us too!
