Free printable Kids’ Encyclopedia
Preschool children understand that when a person comes near an automatic door, a sensor notices, and the power of a machine opens and closes the door.
💬 What Is an Automatic Door?
An automatic door is a door that opens by itself. It opens without needing to be pushed or pulled by hand. You often see them at stores, hospitals, and stations.
🤔 Where have you seen an automatic door?
💬 It Notices When People Come
Above the door, there is a machine called a sensor. The sensor notices when a person comes near. Then it sends a signal to the door that says, “Please open.”
🤔 Where on the door do you think the sensor is?
💬 A Machine Moves the Door
Above the door, there is a machine that moves it. When the motor moves, the door slides sideways. That is why the door opens smoothly.
💬 After You Pass Through, It Closes
After a person passes through, the door closes slowly. If someone is nearby, it may open again. Near an automatic door, we walk instead of running.
🤔 How should we walk near an automatic door to stay safe?
