Lesson
Sensors, Inputs, and Outputs
Students learn how sensors bring information in and how outputs send actions back out.
Sensors, Inputs, and Outputs
What students learn
Students learn that sensors help a robot take in information from the environment, and outputs are the actions the robot performs. Open with to name the sensor types.
Why it matters
Robots do not guess. They sense something, process it, and then respond. shows that a robot reacts to what is happening around it.
Learn the idea
The most important science idea here is the chain from input to action. shows how one piece of information can change the next output.
Try it
Ask the student to list real examples of robot inputs and outputs, such as a light sensor, a sound sensor, a wheel motor, or a blinking light.
Parent guide
Have the student speak in complete sentences: 'The sensor takes in...' and 'The robot outputs...' That structure helps them keep input and output separate.
