A family at home plans a video call with another family. They keep the microphone inside a quiet room rather than take it outside into the wind. The teacher explains that a satellite can carry communication signals. They discuss a communication revolution as a major change, not a reason to assume every new device is better. The school allows supervised practice, and pupils can ask questions when they worry about a message.
