[THEME SONG BEGINS]

>> RACHEL:  Good morning, and welcome to Chompers! Your morning and night tooth brushing show. 

Start brushing on the top of your mouth on one side, and make little circles with your brush around each tooth. 

>> KIDS: 3, 2, 1 BRUSH!

[THEME SONG ENDS]

>> RACHEL: It’s Body Systems Week, and today we have some riddles for you! Ready for your first one?

>> KID: YES.

>> RACHEL:  I’m like a super computer

I handle all your thoughts

I send a lot of messages

What to do and what to not

What am I?

>> GROUP: The brain! 

>> RACHEL: The Brain!

The brain tells your body what to do. It’s part of the nervous system, and it’s connected to all the NERVES in your body. 

Switch your brushing to the other side of the top of your mouth…

[SWITCH BELL]

>> RACHEL: -and give your tongue a brush too.

Let’s say I wanted to wave hello to my friend. First I have a thought, in my brain, that says, “I want to wave to my friend.” Then, my brain tells my arm to raise…

[SLIDE WHISTLE]

>> RACHEL: -the muscles in my arm and hand move my skeleton…

[MARIMBA]

>> RACHEL: -and I wave! That message, “WAVE TO YOUR FRIEND!” travels really fast from my brain to my hand. 

[ZOOM]

>> RACHEL: And then, hopefully, my friend waves back. 

>> WOMAN: Oh, hello!

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

[SWITCH BELL]

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

Alright, ready for your next riddle?

I’m part of a few systems

And can sometimes be a pain

But I handle communication

Between the body and the brain 

So, what body part is this?

[MUSIC BEGINS]

>> GROUP: The spine! 

>> RACHEL: The spine! 

Switch your brushing to the other side of the bottom of your mouth…

[SWITCH BELL]

>> RACHEL: -and don’t forget your molars in the way back.

The spine is part of a few different body systems! It’s made of bones, and so it’s part of your skeleton, or your skeletal system. But the spine is also part of the nervous system!  Remember how when I waved to my friend, it started as a thought in my brain? “I want to wave to my friend.” Well the brain needed some help sending that message to my arm, so the message traveled through the spinal cord…

[MARIMBA] 

>> RACHEL: to my arm! 

[MUSIC ENDS]

>> KIDS: 3-2-1 Spit!
