What a learner can do afterwards

  • Sort a set of objects into 'smart' (responds to input) and 'not smart' (does the same thing every time)
  • Explain what makes a smart speaker different from a regular radio
  • Give an example of a machine that senses something and responds (automatic door, motion-sensor light)

The lesson

Some machines just do one thing. They do it the same way every time. Other machines are smart. Smart machines sense the world. Then they respond to what they sense.

Try it together

A toaster always toasts bread the same way. It never listens or looks around. A smart speaker is different. It listens to your voice. It can answer you back. That makes the speaker smart.

The speaker listens and talks back. That one is smart.
Good to know

Look for machines that sense something. A door that opens by itself senses you. A light that turns on by itself senses you too. Those machines are smart.

Smart machines sense and respond. Not-smart machines just repeat the same thing.
