[THEME SONG STARTS]

>> RACHEL: Good morning, 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!

It’s Science week, and today we’ve got some RIDDLES to work your brain. Here’s your first one: 

When you look at stars and the sun

Or the moon’s cratered face  

You use THIS type of science

The study of outer space

What kind of science is this? 

[MUSIC BEGINS]

>> GROUP: Astronomy!

>> RACHEL: Astronomy. 

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

[SWITCH BELL] and brush your molars in the back of your mouth too.

Astronomy is the study of the stars, planets and space, and it’s one of the oldest sciences. For THOUSANDS of years, people have studied the night sky. Long ago, before there were clocks to tell us what time it is, people used the sun and stars to figure out the time. And ancient sailors used the stars to travel the seas, and to make sure they didn't get lost!  

[WATER SHIP]

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

[SWITCH BELL]

>> RACHEL: -pick a side and keep brushing! 

Here’s your next riddle: 

This science says to do no harm

It’s what all doctors learn

It’s also what you take when you feel sick

Or use to treat a bur n

What science is this? 

GROUP: MEDICINE

>> RACHEL: Medicine 

Medicine isn't just what you take when you're feeling yucky, it's also the name of the science that doctors practice.

>> RACHEL: Switch to the other side of the bottom of your mouth... 

[SWITCH BELL]

>> RACHEL: -but keep making circles around each tooth with your brush. 

Medicine is the science of helping people get healthy, or stay healthy. Most people say that the science of Medicine was started by a doctor from long ago named Hippocrates. Hippocrates was one of the first people to write what knew about medicine into a book - so doctors after him could learn it too!
