### In the lessons

In science, radio waves are invisible waves that travel at the speed of light; they carry sound for radios, signals for phones and TV, and are used in space. In safety, in a storm or emergency a battery or wind-up radio gives news and warnings. Walkie-talkies are small two-way radios. Phrases: on the radio, listen to the radio, turn on the radio, radio station, radio waves, radio contact.
