Sarah and Maria made a telephone using two cans and a string. It was a very long string. Maria went upstairs in her house and Sarah stayed downstairs. Maria spoke softly into the can. "I can hear you!' Sarah said back. How can this happen?

• Sound waves travel through a vacuum.

• Sound waves travel from high to low.

• Sound waves travel through solids like the string.

• Maria talked so loudly that Sarah could hear her without the phone.
