let's start with our top story for this week. it's one of the world's most deadly diseases -- ebola. so, it's no surprise that to fight it, it takes a world of cooperation and a lot of resources. and that costs money. to raise funds and awareness of ebola, a concert was held at the united nations, and "teen kids news" was there. >> when you think of fighting ebola, you wouldn't think that one of the most powerful weapons would be a red carpet. but it is. >> we are here to support the families who are suffering from all the ramifications of ebola. >> it's about every human having the right to treatment, and i think that it's a global

it's not west africa's problem. >> the a-listers were all here to help raise money to fight ebola and to show their appreciation. >> god bless. god bless america to help us. thank you very, very much. >> one performer taking part in the night's concert is this teen rapper. >> i personally feel that being african-american, i have african roots, and, you know, i can't allow somebody else to just die off of a sickness that can be such easily avoided. that's where my heritage comes from. >> nico gave us an impromptu preview of his rap song. >> as a people, we are here to survive the pain that we feel lets us know we're alive you can't stop now turn the will into drive have the will of the lord with your hands to the sky >> the concert was held in the giant room where the u.n. general assembly usually meets.

raging so high in west africa >> this group is called "one voice." although comprised of musicians from several different african countries, the message is the same -- ebola can be beaten. >> all the people in the world, in the nation, all affected by this plague's wicked implication hope for our soul and the light that we bring tomorrow's always better with the soul and that we sing >> the gala ended on a high note, with nico in the spotlight. >> it's a check on my list we can do it all together, and turn our hands into fists stand tall together we can win i'm shouting out, reaching out for a limb the world goes on won't stop till it's over not until the world lives free of ebola >> the concert was a big success. the organizers say the money raised will go a long way to help those battling ebola. for "teen kids news," i'm eric. >> coming up, what we need to know about hurricanes.

back. >> katrina, ike, and sandy. for most of us, those are just

but for thousands of people along our nation's gulf and east coasts, those names are reminders of the incredibly destructive power of nature. emily tells us more. >> katrina in 2005, ike in 2008, and sandy 2012. all were powerful hurricanes that slammed into the u.s. in recent years. their winds, rain, and flooding caused tremendous damage. so, no wonder that the more we learn about hurricanes, the better. dr. radley horton is an expert on these super storms. he's a climate scientist at columbia university. welcome. >> thank you. it's good to be here. what's the definition of a hurricane? a hurricane is a storm with very strong winds. it's a storm that forms over the warm waters of the tropical oceans, and as soon as that storm's winds get up to about 35 miles an hour, we call it a tropical storm. and if if its winds get up to 75 miles an hour, it's a

>> how are hurricanes classified? >> hurricanes are classified by how strong their winds are. a category 1 hurricane, which is the weakest, has winds just above 75 miles an hour. category 5, which is the strongest, is winds at around 150 miles an hour. >> so, what causes these hurricanes? >> hurricanes are caused by a combination of factors. several things have to come together for you to get a hurricane. one of the most important things is a warm ocean. hurricanes form over the warm waters of the tropics. with the warm sun beating down, when temperatures get to be about 80 degrees fahrenheit, conditions are right for a lot of evaporation, which provides a lot of power to hurricanes. >> have hurricanes become more common or stronger in recent years? >> we need the next generation of young scientists to answer a lot of questions about hurricanes for us, but there are some things that we know right now.

been rising as the oceans warm and as the atmosphere warms. as those sea levels rise, we're seeing worse coastal flooding because of those seas rising higher. it seems like hurricices in the atlantic have become a little more frequent in recent years, and the best research tells us that the strongest hurricanes may get stronger. but there are a lot of things we don't know about hurricanes. we know that the oceans are gonna continue to warm up, but what's gonna happen to winds in the atmosphere? that's gonna be a big thing that determines how hurricanes change in the future, and we need that next generation of young scientists to help us answer those questions. >> what's the connection between global warming and hurricanes? >> as we've increased the amount of greenhouse gases in the atmosphere, temperatures have gone up in the air, and they've also gone up in the ocean. as the ocean warms, hurricanes can become that much stronger. but there are other things that impact hurricanes, as well, things like the winds in the

shear, which is the difference in height in the atmosphere. we don't know with climate change how wind shear might change in the fututu, and until we know more about that, we can't say for sure how hurricanes are gonna change. but what we do know is that as sea levels continue to rise, we're gonna see more coastal flooding, even if hurricanes don't change at all. >> thanks, professor. >> thank you. >> just to give you an idea of how powerful these storms can be, experts say a big hurricane releases the energy equal to 10 atom bombs every second. >> ever take a close look at your state flag? you should, because you might be surprised at how much you can learn from it. >> the name "nevada" comes from the spanish phrase, "sierra nevada," which means "snow-covered mountains." the sierra nevada range rises along the state's western

in 1857, a huge deposit of silver, known as the comstock lode, was discovered. prospectors flocked to nevada seeking their fortunes. settlements quickly grew into towns. not only did nevada change, its state flag would change many times. >> nevada's original flag was quite garish. it had big stars. it had the word "silver" on it, the word "gold." >> over the years, the flag was changed at least three more times. and the slogan "battle born" was added. >> and that's because nevada was added to the union during the civil war. >> the slogan rests upon a sagebrush wreath that partially surrounds "nevada," and a large silver star. the star represents the importance of silver throughout nevada's history. huge quantities of silver still flow out of nevada's mines each year. and huge quantities of silver flow into nevada, as well, thanks to the thousands of slot machines in the state's most famous city -- las vegas.

veronique. >> there's lots more ahead on

we'll be right back. >> here's eden with another report in our babysitting tips series. >> not all babysitting jobs are paying jobs. we're often drafted by our parents to sit for our younger brothers or sisters. whether you consider that a pleasure or a pain comes down to how you approach the task. dr. connie hebert is the author of "the teachable minute." welcome, dr. connie. >> hi. thanks for having me. >> so, how do we make sitting for a sibling fun for both of us? >> well, you want to remember that younger kids, your younger brothers and sisters, want to be with you. they don't want to see you on your phone or in front of the computer or the tv all the time. they want to do some things with you.

teachable minutes with them, and then they'll be more fun and you'll have more fun. >> so, give me an example of catching a teachable minute to make it more fun. >> all right, so let's say that you want to play a math game sister. just start out by asking what's 2 times 4, and then they give you the answer, or you can do pluses or minus. doesn't matter. so, let's say you did 2 times 4. they give you the answer, and then you add minus 5, and they give you the answer. plus 10, and they give you the answer. and it's kind of fun cause you're thinking of ways to get them to think. in the meantime you're thinking. so, it's a great way to go back and forth with math. >> okay, how about science or history or english? is there anything there that we can do to make a fun game? >> yeah, well, we can go outside, and we can look at some really neat things in the backyard. kids are really curious about nests and antstsnd how animals

might be living there. there's a lot of things you can do outside. you can also do some mapping skills with kids. you can draw maps together. you can color together while you're watching tv. you may think coloring is something that only little kids do, but it's fun to color, and kids really like to see what you create and what colors you use, and why you use them. and so, coloring with your younger brother or sister is something fun to do, too, and it helps them with their handwriting. >> terrific. well, thanks, dr. connie. >> glad to be on the show again. catch some teachable minutes with your younger brothers and sisters, and they will love and appreciate you forever. >> as dr. connie says, your younger sister and brother just want a little of your time and attention. and what will you get? a whole lot of love. >> triple crown winners are very scarce in baseball history, but

the triple crown is when a batter leads the league in three major offensive categories -- batting average, home runs, and rbis. 17 players have won the triple crown. most recently, in 2012, miguel cabrera won the triple crown. other than cabrera, every single triple crown winner is in the hall of fame. i'm matt with "teen kids news." >> this important message is brought to you by the national road safety foundation. >> on the court, you want to crowd your opponent. it's called "setting a screen." but on the road, crowding is dangerous. >> it's called "tailgating." >> green 18. hike! >> in football, you want to take advantage of blind spots. >> but when driving, don't be blindsided by blind spots. >> so, before changing lanes... >> check that no one's in your blind spot. remember, always share the road. >> this is a message from the

>> coming up, we'll take a tour of a fascinating museum that

years of flight. >> from up high, this looks like a very crowded airport. but it's actually a century of aviation history frozen in time. this is the pima air & space museum. located in a tucson, arizona, desert, it's home to some of the most important and unusual machines to ever fly in the sky. this is quite an impressive >> well, thanks. you know, we've been working hard at it for about 35 years now, so we're very proud of our accomplishments. >> one of the most popular exhibits is the blackbird. it's the world's fastest jet. the blackbird was designed to outrun missiles trying to shoot it down. that's because the u.s. used blackbirds to spy on other countries.

they were flying high and fast long before anyone acknowledged that the program existed. but in the late '70s, i believe 1978, one of the blackbirds flew from los angeles to new york city in 1 hour, 4 minutes and 6 seconds. >> wow! i wish all flights from new york to los angeles were that fast! >> yeah, no, exactly. but the in-flight services aren't that great. >> so, what was its top speed? >> generally it was a little bit over mach-3. >> mach 1 is the speed of sound. so, mach 3 means flying at three times the speed of sound. >> s s we're getting into 2,100, 2,200 miles per hour. >> wow! next on the list was one of the world's smallest planes, the bumblebee. with so many aircraft in the hangar, i was afraid i would miss finding it. but i needn't have worried. so, i'm guessing this is the bumblebee. >> what tipped you off? >> [ laughing ] i don't know! its official name is the "starr bumblebee."

a pilot named bob starr. i would have trouble fitting in there. how did he fit in there? >> bob was a really sort of slightly built guy, right? so, he sort of squirmed himself in. >> the little plane only carared two and a half gallons of gas. so, the flight of the bumblebee was very, very short. i'm just surprised it made it off the ground. >> yeah, well, you know, one of the reasons he kind of named it "bumblebee" is, you know, there's the old myth that you know if bumblebees knew anything about physics they wouldn't be able to fly, right? so, that's kind of where he took the theme from. >> up there is a concept that really needed to "be" aware of the physics of flying. that looks like a one-man flying machine. >> it is. it's a one-man hoppicopter. it was meant to drop soldiers into battle with their own personal helicopter. interesting idea but terrible application. all it did was break legeg and it was abandoned really quickly. >> oh, no! so, it didn't work? >> didn't work.

with craft, outside looked like a ginormous airplane parking lot. >> so, we're here in front of one of my personal favorites in the collection, and probably in my opinion one of the most genuinely historic aircrafts we have here. it's a boeing nb-52a. this is the first series of the stratofortress strategic nuclear bomber. >> this plane was built in 1954. at that time, america was on constant alert in case of nuclear attack by the soviet union. if that had happened, the b-52 would have been sese to bomb the sovivis. fortunately, there was never a world war iii. so, instead, this stratofortress played an important role in the eaeay days of america's space program. it would carry a rocket plane up to the edge of earth's atmosphere and then release it. this was one of the ways pilots practiced to become astronauts. >> you know, neil armstrong, the first man to walk on the moon, did mission drops off of this airplane, so it's a really -- >> this specific airplane? >> this specific airplane. it's really, really fantastic

>> when "teen kids news" returns, we'll tell you why the u.s. air force went from

candy. >> we're at the pima air & space museum in arizona. historic aircraft of all kinds are on display. this plane is older than most of our grandparents. but that's not why it's here. it's actually a rather sweet story. this plane is called the "candy bomber." that's also the name of the man who flew it. i became the candy bomber because of kids. kids and chocolate go together. >> it was 1948. world war ii had recently ended. germany was defeated, devastated, and divided. the victorious allies cut up the

with each ally controlling its own sector. the area where people lived in freedom was called west berlin. the area where people e ved under the iron boot of soviet communism was called east berlin. this film by the u.s. government helps to explain what it was like to live in postwar berlin. >> two and a half million people, more than half of berlin's population, lived in the american, british, and french zones. but the whole city was surrounded by the soviet zone of germany. supplying the two and a half million people of the western sectors was a system of rails, canals, and roads. >> but the soviets wanted berlin all to themselves. so, they set up a giant blockade, cutting off the roads and railroads to west berlin. >> the suspension of all traffic successfully blocked all surface access to the city. the soviets claimed that technical difficulties caused the stoppage. the truth was that they were trying to force the western allies to surrender their

and the weapon was hunger. >> with no food or supplies able to get in, the soviets expected the allies to pack up and leave. but they didn't. the united states and its allies refused to abandon the people to be starved into accepting soviet rule. there was a big problem, though -- how to feed more than two million people trapped in west berlin. it seemed like an impossible undertaking. but the allies had a plan. they'd bring in supplies by air. it was known as the berlin airlift. >> army, navy, and air force working together gave an inspiring example of joint action, and we mustn't forget that the british and the french gave much help. >> it was a massive operation -- bigger than any airlift ever before. planes were landing in west berlin every three minutes every hour of the day every day of the week for months. >> not long before, we had been

peace. now we were delivering bread to maintain that peace. the airlift cargos kept the city alive. >> one of the heroic airlift pilots was colonel halvorsen, although he was a lieutenant back then. on his day off, he came across some german children gathered at the edge of the airport. >> it was a tough time for kids in berlin. most of them had single parents. parents were killed -- the father or the mother during the war. >> he knew they were hungry. all he had in his pocket to give them were two sticks of gum. he was touched by how the kids carefully broke the sticks into tiny pieces so that each could get a share. that gave him an idea. he told them to watch for his plane the next day. he would wiggle his wings as he came in for landing. >> and i said, "you come back and stand in the space between the bombed-out buildings and the barbed-wire fence, and then the runway. stand in that open place.

to land -- i'll just be in the air a ways -- i'll drop enough chocolate out of the airplane for all of you to have a piece." >> during the night, he turned handkerchiefs into candy parachutes. as he approached the airport the next day, he wiggled his wings, and the legend of the candy bomber began. every time he flew to berlin, he and his crew would drop candy to kids waiting below. >> and then the news got out, and it was all over the world. >> he thought he'd get in trouble, but his commanding officer realized the candy brought happiness during a difficult time. soon, people back home joined in the effort. >> we got a tremendous response from the united states from people who said, "how can we help?" they wrote me and sent handkerchiefs for parachutes and candy bars, and then the american confectioners association through schools in chicopee, mass., sent 23 tons of

>> almost 60 years later, the colonel is still flying and still telling the story. in fact, he recently went to germany, where a school was named for him. there are so many different kinds of planes at this museum, each with an interesting story to discover. >> why is it important to have a museum like this? well, you know, all museums are there to connect us with where we've been. >> it's one thing to read about the great aircraft that played such key roles in making our nation a world leader in aviation. but to be able to walk up and actually touch them? that truly brings history to life. for "teen kids news," i'm nicole. >> that wraps it up for this

we'll see you again next week. every year millions of waterfowl wing their way across the continent in a display unmatched anywhere else in natue. along the way, wetlands provide the resting places and critical resources these waterfowl need to complete their journey. but these rest areas for america's waterfowl and other wildlife are being degraded and destroyed. this is why, since 1937 ducks unlimited has been a world leader in wetlands conservation, ensuring safe passage for nature's most beautiful creations, protection against flooding, and sanctuary for the human soul. if we don't want to grow old in a world without wild places. we must speak up. we must step up.
