Technology can send messages — Technology, 4–6 years
Children learn that technology can carry words, pictures or voices from one person to another. Sending is different from keeping: a message must travel to reach someone else.
Messages can travel
A message is something one person makes for another person to receive. Technology can carry a written word, a picture or a voice far away. The receiver may get it almost at once, even when the people are not together.
Why people send messages
Before phones and computers, people had to wait for a person to carry a letter or speak face to face. People wanted to share news and ask for help when they were apart. Technology was developed to make that sharing travel faster and farther.
Sending a picture
Leo takes a picture of his cat. First, he chooses the picture in the message app. Next, he chooses Grandma’s name and presses send. The picture travels through the network, and Grandma can see the cat on her device.
Making a message is not sending it
A message can look finished on the screen, so it is easy to think the other person has it. But writing or choosing a picture only prepares it. We still need to choose the right person and send it for it to travel.
Keeping in touch
People use phones and computers to send a quick hello, a map or a picture to someone far away. A video call can carry voices and moving pictures at the same time. This is useful when travelling, working apart or checking that someone arrived safely.
