[THEME SONG BEGINS]

>>RACHEL: Hey you’re back! It’s time for Chompers, your morning and night toothbrushing show.

Start brushing on the top of your mouth on one side, but don’t brush too hard.

>>KIDS: 3, 2, 1, brush!

>>RACHEL: It’s Robot week, and tonight we've got more  - WHAT'S THAT SOUND?

[WHATS THAT SOUND THEME]

>>RACHEL: Tonight’s sounds are made by tools that robots use.

Here’s your first one: 

[ELECTRONIC, ECHOEY BEEPS]

>>RACHEL: Here it is one more time: 

[ELECTRONIC, ECHOEY BEEPS]

>>RACHEL: What type of technology makes that sound? Shout it out:

>>GROUP: Sonar!

>>RACHEL: Switch your brushing to the other side of the top of your mouth…

[SWITCH BELL]

>>RACHEL: -and keep on brushing.

Sonar is a technology that uses sound to sense where objects are located. When a machine sends out a sonar sound, the sound bounces back, or echos..

[ECHOEY EFFECT]

>>RACHEL: telling the machine that there’s something nearby. So scientists have created underwater robots that use sonar to check out shipwrecks and map the ocean floor. 

[SPLASH]

>>RACHEL: Switch your brushing to the bottom of your mouth…

[SWITCH BELL]

>>RACHEL: -and brush your front teeth too. 

Here’s your next sound: 

[LENS SHUTTER]

>>RACHEL: What did you think? Here it is one more time:

[LENS SHUTTER]

>>RACHEL: So what’s that sound??

>>GROUP: A camera!

>>RACHEL: The sound you heard was a camera. Many different robots use cameras. I’ll tell you more about that after you:

Switch to the other side of the bottom of your mouth.

[SWITCH BELL]

>>RACHEL: Robots use sensors to get a sense of the world around them. Cameras are a type of sensor used by robots to help them see. Flying robots called drones use cameras to help humans see from way up in the sky…

[HELICOPTER SOUNDS]

And self-driving cars use cameras and other technology to figure out where to go.

[HONK HONK]

[THEME SONG BEGINS]

>>RACHEL: That’s it for Chompers tonight, but come back tomorrow for more toothbrushing. Until then, make sure to rinse before you…

>>KIDS: 3, 2, 1, spit.
