Opening Music - Brain Power! Talk about your fine machine.
Brain Power! Makes you thoroughly unique.
With the power to think you can learn anything. Brain Power!
One hundred billion neurons. Hey! You've got a lot of nerve.
Got their own communication. Transmitting information.
It's electrical...
(Beth) So, how do you think the Spectacular Scientist Club kids did on their mission?
(Juan) I don't know. They are nice kids,
but they are not Junior Scientists like we are.
(Beth) Well, I think it's kind of fun that this is a competition.
I think we can beat them.
It's kind of like playing soccer, but it's science.
(Beth) Oh, Hey Corty.
(Corty) Why are you guys being so competitive?
Scientists work together to solve problems.
It's called teamwork.
(Beth) But, we want to win, triumph, beat the other team.
(Juan) Be the best.
(Corty) Winning is about finding the right answers,
and you can probably do that faster together,
but we'll talk about that later.
For now, we're going to learn about drugs.
(Beth) Drugs. We already know about drugs.
(Juan) We learned about drugs when we were little kids.
(Corty) Well, what you're about to learn isn't kid's stuff.
It's so important that not knowing it can be hazardous to your health.
Juan, can you tell us about the different kinds of drugs?
(Juan) Umm. I don't think we covered that.
(Corty) Well, drugs are categorized into classes,
and one of the classes is stimulants.
(Beth) Oh. Wait a second,
we learned about stimulants like *** and caffeine, like in coffee.
(Juan) Nicotine in cigarettes is a stimulant too, and amphetamines.
(Corty) Do you know what stimulants do?
(Beth) Yea. They make you more awake and active.
They make your heart beat faster, your blood pressure go up
and you get hyper and sometimes even angry and irritable.
(Juan) Whoa. That can't be good for you.
(Corty) It isn't. Your mission is to make a chart that lists each stimulant.
(Juan) That sounds like a great way to learn about stimulants.
We can write down the different stimulants,
record the different names they have, how they're used,
their effect on the body, the brain, and the neurotransmission.
(Beth) That's a tall order.
(Juan) Sure is.
(Corty) But first, to help out,
I'm going to show you a PET scan.
(Juan) Oh. That's like when we took my dog to the vet to have x-rays.
He ate one of my dad's slippers.
(Corty) No. PET stand for Positron Emission Tomography.
But, don't worry about that.
All you need to know is that these PET scans show
a normal brain and a brain affected by stimulants.
(Juan) Lets get started on those charts.
We'll work on them while we take a break and look at them when we come back,
and we want to see your charts too.
[music]
(Corty) That's a very nice chart.
Very impressive. Are you almost done? You do know a lot about stimulants.
Tell me everything you know about stimulants.
(Juan) I think you've had enough coffee, Corty,
it's really starting to go to your head.
(Corty) [Panting] Caffeine is legal. Anyone can get it.
It's in coffee and tea and soft drinks, but it's not a good idea for kids to have caffeine,
even in sodas because it makes you hyper,
and it can cause headaches and sleep problems.
(Beth) Corty, I think you've done enough research for the moment.
You need to take your own advice and lay off the stuff.
(Corty) Huhh. Maybe you're right.
(Beth) But, Corty, if drugs are so bad for you,
then why to people keep taking them?
(Corty) That's a really good question.
Juan, as a Junior Scientist, did you come to any conclusions on that?
(Juan) Well, some drugs are addictive, like nicotine and ***,
so once people start taking them, it can be very hard for them to stop.
Even caffeine can be addictive.
(Corty) That's what I need. A little more coffee. That will wake me up.
(Juan) I don't think so.
(Corty) Well, maybe you're right.
And anyway, I'm on to my next mission.
Got to visit the Spectacular Scientist Club kids.
Later.
Ending Music - Brain Power! Hey what makes you so smart?
It's the brain, it's the brain, it's the brain. You've got the power!
