MICHAEL BLOOMBERG, MAYOR, NEW YORK CITY: Let me say that we are very lucky. Thanks to alert New Yorkers and professional police officers, we avoided what could have been a very deadly event.

CARL AZUZ, CNN STUDENT NEWS ANCHOR: That story out of New York City leading off our show today. I'm Carl Azuz. This is CNN Student News.

First Up: Times Square

AZUZ: Things are more or less back to normal in New York's Times Square. The area was put on lockdown for a while over the weekend, and here is why: Saturday night, someone left an SUV with the engine running on the street. A T-shirt vendor noticed it, saw smoke coming out of it, told a nearby police officer. The officer looked inside and spotted what authorities think might have been a bomb. That's what triggered the lockdown. Times Square is usually filled with tourists and people going to the theater. Authorities immediately evacuated the area. You can see some of that in this iReport. Some people were moved out of Times Square. Others were kept inside the hotels or theaters they were already in.

Eventually, the bomb squad was called in. That's the guy in the gray suit just to the left of center of your screen there. Inside the SUV, they found a device made from gasoline cans, propane tanks, fireworks and electric clocks. Police say it apparently didn't work. Instead of exploding, it just filled the SUV with smoke. The vehicle was taken out of Times Square yesterday. Officials have started an investigation into the whole thing. They're checking the vehicle and its contents for fingerprints. They're going over surveillance footage and amateur videos from Times Square to see if they can identify who left the SUV there. Authorities are treating this incident as a potential terrorist attack.

Gulf Coast Oil Spill

AZUZ: Next stop, Louisiana. Officials there are making some predictions about an oil spill in the Gulf of Mexico. Ken Salazar, the secretary of the interior, is warning the region to prepare for the worst. Several government officials think the leak could continue for weeks. The fishing industry in part of the Gulf will be shut down for at least 10 days.

All of this started with an explosion on an offshore oil rig last month. The rig sank; it caused a leak. And now, more than a million and a half gallons of oil have spilled into the Gulf. The Coast Guard and the company that owns the rig are both doing what they can to contain this spill. President Obama, who visited the region yesterday, says those efforts will keep going for as long as it takes.

U.S. PRESIDENT BARACK OBAMA: I'm not going to rest, and none of the gentlemen and women who are here are going to rest or be satisfied, until the leak is stopped at the source, the oil on the gulf is contained and cleaned up, and the people of this region are able to go back to their lives and their livelihoods. Currently, the most advanced technology available is being used to try and stop a leak that is more than 5,000 feet under the surface. Because this leak is unique and unprecedented, it could take many days to stop. That's why we're also using every resource available to stop the oil from coming ashore and mitigating the damage it could cause.

Severe Storms

AZUZ: North from the Gulf Coast, a couple states are recovering from severe weather. Parts of Arkansas were hit by heavy storms, possible tornadoes on Friday. One person was killed. About two dozen others were hurt. Meanwhile, "extremely dangerous" flooding in Tennessee is responsible for at least five deaths over the weekend. Nashville got between 6 and 10 inches of rain in just 12 hours on Saturday. The city's mayor called it "one of the most severe rain events Nashville has ever experienced." He urged people to stay home and off the roads. There was more rain in the forecast for Tennessee yesterday.

Teacher Appreciation Week

AZUZ: Well, it's time to give a little thanks to your teachers! This is Teacher Appreciation Week. And to celebrate, we want you to head to our blog and talk about your favorites. But put some thought into this one. Tell us how your teachers make a difference in your lives. It could be by showing you CNN Student News. If you want to go for some extra credit, and we know you want some extra credit, send us an iReport for Teacher Appreciation Week. You can do it all at CNNStudentNews.com.

Immigration Reform

AZUZ: The issue of immigration getting a lot of attention right now. Part of the reason seems to be a new law in Arizona. We covered that last week. The law requires any immigrants in Arizona to have immigration documents with them at all times. It also requires police to question anyone who might be in the U.S. illegally.

Over the weekend, thousands of people protested the Arizona law. Officials said 50,000 people marched in this demonstration in Los Angeles. There were similar protests in New York, Washington and Arizona. Critics of the law argue it will lead to racial profiling. They claim police will question people about their immigration status based mostly on their race.

Now, Arizona Governor Jan Brewer is working to address that criticism by making some changes to the law. She signed those changes into effect Friday. This is the big difference. Originally, police officers in Arizona could stop anyone based simply on a "reasonable suspicion" that they might be in the country illegally. Now, officers can only ask people about their immigration status while the officers are enforcing some other law; maybe speeding, maybe loitering. Governor Brewer says the changes "make it crystal clear and undeniable that racial profiling is illegal and will not be tolerated in Arizona."

Shoutout

TOMEKA JONES, CNN STUDENT NEWS: Today's Shoutout goes out to Ms. Killey's social studies classes at Haven Middle School in Evanston, Illinois! What type of musician is most likely to perform a cappella? You know what to do! Is it a: A) Cellist, B) Guitarist, C) Drummer or D) Singer? You've got three seconds -- GO! Since a cappella means "without instrumental support," a singer is the right choice here. That's your answer and that's your Shoutout!

Virtual Choir

AZUZ: Nearly 200 singers raised their voices in a choir performance recently. They didn't need any instrumental support, but they did get some help from technology. When the curtain went up, they weren't really there! John Vennavally-Rao takes note of how the ethereal ensemble came together.

(BEGIN VIDEO)

JOHN VENNAVALLY-RAO, REPORTER, CTV NEWS, TORONTO: At first, it may seem strange that Patrick Murray is all alone, given choirs are all about making music together.

PATRICK MURRAY [SINGING IN LATIN]: Singing "Lux Aurumque."

VENNAVALLY-RAO: The 20-year-old music major at the University of Toronto, singing to his computer a popular choral piece called "Lux Aurumque."

MURRAY: I recorded a video on my webcam along with the audio and then uploaded it to YouTube.

VENNAVALLY-RAO: On its own, a rather ordinary video. But Karen Koh of Singapore did the same. So did Steven Hansen in Sweden. And Melody Myers of Tennessee. Videos that kept coming in on YouTube, the different parts of the same song.

MELODY MYERS OF TENNESSEE, [SINGING IN LATIN]: Singing "Lux Aurumque"

VENNAVALLY-RAO: All singing to an instructional video from composer-conductor Eric Whitacre.

MURRAY: Everybody had to sync up their video to his video at the start of this beep.

VENNAVALLY-RAO: Producer Scott Haines put all those clips together; this, the extraordinary result: the conductor and the 185 voices on YouTube.

MURRAY: These people are from everywhere. 12 different countries represented in this video.

VENNAVALLY-RAO: A choir unlike any other.

MURRAY: There are people in Austria in this video. I've never been to Austria and maybe I never will, but here I am in this video singing with someone in Austria.

VENNAVALLY-RAO: Composer Whitacre wrote he found the final product overwhelming. The poetic symbolism about our shared humanity and the need to connect.

MURRAY: All you needed to participate was a webcam and a microphone. I think it's the future of creating music.

VENNAVALLY-RAO: And Whitcare says he hopes to one day compose an original piece for the virtual choir with hundreds, perhaps thousands, of people singing alone, together.

Before We Go

AZUZ: Really great stuff there. Well, last but not least today, it's not a sun dress. It's a Capri-Sun dress! And it's not just for senior prom, it's for a senior project! If not Project Runway. The ingredients: 117 packets of juice! One boyfriend to help drink all that juice. Some thread, some hot glue, three weeks to assemble. All of it added up to a passing grade and a one-of-a-kind, if not comfortable-kind, of couture.

Goodbye

AZUZ: Now, if you're unsure how to address such a dress, just remember that in fashion, you always reap what you sew. We are piecing together more stories for you, so tomorrow, be sure to try us on for size. I'm Carl Azuz; we'll see you then!

CARL AZUZ, CNN STUDENT NEWS ANCHOR: Arbor Day is awesome! Especially when it falls on a Friday. To celebrate, we are branching out into a bunch of topics in today's show. I'm Carl Azuz. Let's get to it.

First Up: Oil Update

AZUZ: The federal government will use "every single available resource" to help contain that oil spill in the Gulf of Mexico. The secretary of Homeland Security declared it an incident of "national significance." What that means is that resources from other parts of the country can be used to try and control the spill. Louisiana Governor Bobby Jindal already declared a state of emergency to help free up resources for the effort. Yesterday afternoon, the oil was about 16 miles off the Louisiana coast and headed toward shore. When it does start hitting the coast, it could threaten hundreds of species of wildlife: birds, shrimp, crabs, otters. In fact, the entire Gulf Coast fishing industry could be affected.

Yesterday, we told you that the Coast Guard was going to try and contain part of the spill by setting it on fire. They did; you can see the smoke from that fire right here. They were hoping to set another controlled burn yesterday, but the weather wasn't cooperating. Some authorities think this spill is getting worse, much worse. At first, the estimate was that the spill was leaking out about a thousand barrels of oil per day. Now, the Coast Guard is saying that's increased to as many as 5,000 barrels. That's more than 200,000 gallons per day.

Financial Reform

AZUZ: The Senate is ready to debate a financial reform bill. When you hear the word debate, you mighty think of people being on opposite sides of something. This time, everyone agrees! They all want to debate. Republicans and Democrats had been working on this bill in private sessions. They disagreed on some parts of it, and the Republicans -- plus a few Democrats -- blocked it from moving forward until those differences could be worked out. Late Wednesday, they changed their minds. Every senator, Republican and Democrat, voted to start debate.

Immigration Reform

AZUZ: The Senate's looking at taking up another controversial issue: immigration reform. Some Democratic senators were planning to release a new proposal late yesterday. It would increase the number of border patrol officers and make it tougher to hire illegal workers. Plus, it outlines a process to legalize the millions of illegal immigrants in the U.S. One Republican leader says the proposal is just an attempt to get voters out for November's midterm elections. He says there's no chance that immigration reform will move through Congress. Some Democratic sources say the same thing, that the odds of this passing the Senate this year are pretty slim.

Word to the Wise

MATT CHERRY, CNN STUDENT NEWS: A Word to the Wise...

calorie (noun) a unit of energy or heat that is often associated with food

Fast Food

AZUZ: Your body needs calories for energy; they fuel everything you do. But if you get too many of them or don't burn them off with exercise, those calories can turn to fat. Lawmakers in part of California say that some fast food kids' meals have too many calories. They believe one way to discourage kids from wanting those meals is to ban the toys that come with them. So, the new rule in Santa Clara, California: kids' meals with more than 485 calories get no toy. Kids' meals with less calories can still include the toy. There are also limits on fat and sodium, or salt. One lawmaker says this will help fight childhood obesity and "breaks the link between unhealthy food and prizes." But the California Restaurant Association thinks the rule goes too far, and some critics say parents should be responsible for what their children eat.

Blog Promo

AZUZ: This led us to consider a question that's kind of like the video game question we asked the other day: Who's responsible here? Who should decide on calories? Is it the government? Should restaurants be responsible? Should parents be responsible? Go to our blog, tell us your opinion. The address: CNNStudentNews.com.

This Day in History

(ON SCREEN GRAPHIC)

April 30, 1789 - George Washington is inaugurated as first president of the United States

April 30, 1803 - Negotiations conclude on Louisiana Purchase, which doubles the size of the United States

April 30, 1975 - South Vietnam surrenders to the North, ending the Vietnam War; remaining Americans are evacuated from Saigon

Shoutout

TOMEKA JONES, CNN STUDENT NEWS: Today's Shoutout goes out to everyone whose parents serve in the U.S. Armed Forces! What branch of the U.S. military was founded first? If you think you know it, shout it out! Is it the: A) Army, B) Navy, C) Air Force or D) Marines? You've got three seconds -- GO! The U.S. Army was established first, way back in June of 1775. That's your answer and that's your Shoutout!

Military Child

AZUZ: The Month of the Military Child pays tribute to people whose parents serve in all branches of the military. 1.7 million American kids have a parent who serves, and this month recognizes their sacrifices; for example, when your mom or dad is away for months at a time. Sandra Endo shows us how the military is helping families stay in touch.

(BEGIN VIDEO)

SANDRA ENDO, CNN CORRESPONDENT, WASHINGTON, D.C.: So, where's your daddy at?

AMARI LUNN, MILITARY CHILD: On a ship.

ENDO: On a ship?

ENDO: Three-year-old Amari Lunn can't wait for daddy to come home.

FAINA LUNN, MARRIED TO U.S. NAVAL OFFICER: I have to explain to him that daddy's working. But he's like, "But when is daddy coming home?"

ENDO: Daddy is Navy Chief Gary Lunn, currently on the USS Dwight Eisenhower, deployed in the North Arabian Sea. Lunn has been deployed for six months; his family eagerly awaits his return.

F. LUNN: Where do you see daddy? Do you see daddy on the TV?

A. LUNN: Yeah.

ENDO: This is Lunn's 9th deployment. But this one is different thanks to a program his kids affectionately call the "Daddy Show."

F. LUNN: Press play. Back up so you can see daddy.

ENDO: Through a non-profit program called United Through Reading, deployed service members can choose a book and record videos from their base to read aloud to their children.

CHIEF GARY LUNN, U.S. NAVY: Today, I'm going to read, the book is called "The Ear Book."

A. LUNN: "The Ear Book!"

ENDO: Programs like this one that help keep families connected are becoming increasingly popular in the military. When service members with kids are deployed for long stretches, psychologists say it's the children who feel it the most.

LYNETTE FRAGA, ZERO TO THREE: Some children may withdraw and you have a difficult time talking about their experience. Or some children are very aggressive and you might see them crying a lot or having trouble sleeping.

ENDO: But with these videos, smiles often replace tears, especially for the Lunn family.

ROMELLO LOVINSKY, MILITARY CHILD: It's, like, better because I get to see him and he'll get to talk with me and stuff on the videos.

ENDO: Do you see a difference in your kids?

F. LUNN: Yes, yes. Now, he thinks daddy's around more.

ENDO: It's also a major morale boost for the parent serving far away.

G. LUNN: I know it's helping me out a lot, especially knowing the response that's coming from it. Just mentally, calming me down and enabling me to stay focused at my job.

I love you. I love all of you. Muah!

A. LUNN: Muah!

ENDO: With the country engaged in two wars and many service members facing multiple deployments, the military is expanding and promoting programs which help ease the strain on families. Sandra Endo, CNN, Norfolk, Virginia.

Comments

AZUZ: Okay, at Facebook.com/CNNStudentNews, a student named Adrian called our attention to the Month of the Military Child. He told us about his experience as one -- the service and the sacrifice -- and we asked for your experiences as well. Cory described it as an adventure, just by moving around and making new friends along the way. Ryan says it can be hard to keep friendships with the frequent moves, but that he's grown up learning respect and flexibility. Nate says the hardest part is the time his dad spends away from home, but that he couldn't be any more proud as his son. And Kevin says it's hard because his family makes sacrifices, but it's for a big cause. We thank and salute all of you military kids out there for your sacrifices.

Before We Go

AZUZ: And before we leave you today, you've heard of electronic music. This would be the literal version: a mechanical marimba player. He's not just banging out some pre-planned tune, either. This is jazz, and he's improvising, learning what his fellow musicians are doing and then adapting to it. At least, that's what they claim. Now, before any of you get worried about robots ruling the music industry, the point here is the interaction: man and machine working together.

Goodbye

AZUZ: And that sounds just fine to us, because do you really think a robots-only band would play jazz? There's no chance. They'd totally be metal. Sunday starts National Teacher Appreciation Week. So, while you've got some time over the weekend, why not send us an iReport with a Shoutout to your favorite teacher? You, and I mean you, could be featured on our show! Find out how to send us an iReport at CNNStudentNews.com. We'll see you on Monday. Have a great weekend.


CARL AZUZ, CNN STUDENT NEWS ANCHOR: When it comes to the stock market, are you smarter than a first grader? Better wait a few minutes before you answer. I'm Carl Azuz. This is CNN Student News!

First Up: Oil Rig

AZUZ: Authorities around the Gulf of Mexico are in a race against time. They are trying to control an oil spill that's heading toward the Louisiana shore. Yesterday, it was about 23 miles off the coast of Louisiana. It could reach land by Friday. If that happens, officials say it could create an ecological disaster. This is all from the Deepwater Horizon. That's the oil rig that sank in the Gulf last week. The company that owns the rig is trying to stop the leak underwater. Meantime, authorities on shore are trying to block the oil from getting to sensitive areas. Reynolds Wolf takes us over the spill to get a closer look.

(BEGIN VIDEO)

REYNOLDS WOLF, CNN METEOROLOGIST: From the air, the spill appears massive. You can definitely see it.

LT. CRAIG MURRAY, U.S. COAST GUARD: Those are skimmers and booms trying to recover oil.

WOLF: Even from this height, there's plenty to see. On the surface, there's a little bit of a rainbow-like sheen, and much of that is going to be burned away by the sun's rays. But there's also a thicker layer of crude oil in places, and all of that's going to have to be skimmed away. NOAA scientist Ed Levine says the oil moves with sea currents and winds, both affecting the slick shape and size.

ED LEVINE, NOAA: Probably about 97 percent of the floating oil on the surface is very thin sheen. Sheens, molecules thin, thinner than a coat of paint on the side of your house. The area where the thick oil is is in about that three percent of the surface.

WOLF: Currently, the slick continues to grow. And scientists estimate the well is leaking some 42,000 gallons of oil a day. Failure to contain could be catastrophic to the people, beaches and businesses along the Gulf Coast.

LEVINE: The thing we're trying to minimize is land impacts because of the environmental and socio-economic damage that it can do. One of NOAA's concerns is also guaranteeing the safety and security of the seafood, that no tainted products get to market.

MURRAY: The previous location of Deepwater Horizon is at 11:00.

WOLF: And it's going to take a huge effort as we fly over the location where the Deepwater Horizon was once operational. All that remains is a blanket of oil and boats.

MURRAY: The number of assets on scene each day increase.

WOLF: Working to stop the leak and what Coast Guard officials say might become one of the most significant oil spills in U.S. history. Reynolds Wolf, CNN, over the Gulf of Mexico.

(END VIDEO)

AZUZ: You heard in that report that the sun is going to burn away a lot of the floating oil. Another way to do that: set it on fire! It's called a controlled burn, and it's designed to get rid of a lot of the oil. The Coast Guard was preparing for that yesterday, but they're waiting on right weather conditions to get started.

I.D. Me

MATT CHERRY, CNN STUDENT NEWS: See if you can I.D. Me! I'm a desert that covers parts of Arizona, California, Nevada and Utah. I'm home to the Joshua Tree National Park. And I'm named after a group of Native Americans. I'm the Mojave Desert, and I take up more than 25,000 square miles.

Cross Controversy

AZUZ: The U.S. Supreme Court says that a memorial out in the Mojave Desert does not violate the U.S. Constitution. The memorial is a large cross. It was put up in 1934 to honor fallen soldiers. But it's located in a national park, and some people argue that it's a religious symbol that goes against the concept of separation of church and state. The cross -- which you can see right here -- was boarded up because of the legal battle. Yesterday's Supreme Court decision was close: 5 to 4. Writing for the majority, Justice Anthony Kennedy said that this cross represents "far more than religion." But in opposition, Justice John Paul Stevens argued the government can't lawfully endorse a religious symbol as a way to pay tribute to veterans.

Facebook Promo

AZUZ: We have a new video up on our Facebook page. It's all about the month of the military child, which is right now! April! We're gonna have more about this on our show later this week. Now, maybe you know someone who's a military child, maybe you are one. Either way, we'd love for you to head to Facebook, check out this new video, share your thoughts. You might see them on a show later on this week.

Thailand Clashes

AZUZ: Both the United States and the United Kingdom are telling people not to travel to Thailand unless it's absolutely necessary. The reason is violent political unrest. It has gripped the Asian country for a while now, and fighting broke out again yesterday. Police forces facing off against protesters who are opposed to the government. A CNN reporter on the scene described it as a "tense and intense standoff." She said police used rubber bullets and live ammo. Thailand's government has actually made rules about this. It says troops can use tear gas if protesters get within about 100 yards and live ammo if the protesters get within 100 feet.

Greece

AZUZ: Over in Europe, the financial outlook for a few countries isn't looking too good. The investment ratings for Spain, Portugal and Greece all went down this week. Greece might be the worst situation. Experts are using the word "junk" to describe that nation's investment rating. Basically, they're saying that it's very risky to put your money there. Greece has a massive debt, nearly $400 billion. That's bigger than the country's economy. Greece is developing ways to cut spending, but Greek workers aren't too happy about some of those plans, and they've been protesting about it, like you see here. Greece is also asking for financial help from the European Union: a bailout of more than $50 billion.

Shoutout

TOMEKA JONES, CNN STUDENT NEWS: Today's Shoutout goes out to Mr. Naas' social studies classes at Mahaffey Middle School in Fort Campbell, Kentucky! Which word describes a portion of earnings given to someone who owns stock in a company? Is it: A) Dividend, B) Security, C) Bond or D) Interest? You've got three seconds -- GO! When a company makes money, it usually pays its stock holders dividends. That's your answer and that's your Shoutout!

Learning How to Inve$t

AZUZ: Okay, here's your next homework assignment: Take $20,000 and invest it in the stock market. Would you know how to make some dividends? What if you were asked to do the same thing when you were just 6 years old?!? It's not a hypothetical. It's actually happening at a school in Chicago with real kids and real money. Christine Romans explains the reasons why.

(BEGIN VIDEO)

CHRISTINE ROMANS, CNN BUSINESS CORRESPONDENT: Meet America's future investment bankers and accountants.

UNIDENTIFIED FEMALE: We have to look out for the dividends.

UNIDENTIFIED FEMALE: I like checking the Dow.

UNIDENTIFIED FEMALE: My favorite stock would have to be Apple.

ROMANS: At Ariel Academy, students learn how to make money...

UNIDENTIFIED FEMALE: The financial ratio, it helps the business, like...

ROMANS: Save money...

UNIDENTIFIED FEMALE: I think everybody should at least save half of their money.

UNIDENTIFIED FEMALE: Don't forget your decimal.

ROMANS: And invest money, real money, thanks to the school's unique saving and investment curriculum.

CONNIE MORAN, DIRECTOR, ARIEL INVESTMENT CURRICULUM: The incoming first grade class gets a $20,000 endowment. When they get to fifth grade, students will start to choose stocks that they think we should be buying, and we will buy them.

UNIDENTIFIED MALE: Stock prices (INAUDIBLE) $67.58, and the dividend is 14 cents per share.

ROMANS: When students graduate from eighth grade, the $20,000 goes back to the incoming first grade. Any profit above that amount gets split; half goes to improving the school or to charity, the other half gets divided among the kids.

UNIDENTIFIED FEMALE: I'm not going to invest in that at all.

ROMANS: Of course, some years, like 2009, there's no profit, and the kids learn that investing is no slam dunk. But that doesn't deter kids like Ariel graduates Mario and Miles Gage.

MARIO GAGE, ARIEL ACADEMY GRADUATE: I have my own portfolio and it's just really amazing. I'm able to take everything that I learned at Ariel to the next level.

ROMANS: Miles and Mario weren't the only ones in the family getting an education.

MICHELLE GAGE, MOTHER OF ARIEL ACADEMY GRADUATES: And I started looking over some of the materials that they were bringing home. It was still a little foreign to me, but then they kind of broke it down, like children do, and I started getting a little excited about that, and then the knowledge, and I'm like, wow. You know what? This is fun.

ROMANS: Fun and finance doesn't often appear in the same sentence, but that's not true at Ariel. Christine Romans, CNN.

Before We Go

AZUZ: Before we go, we've got a little bedtime story for you. But it won't make you tired. It's the annual Great Bed Races in Louisville, Kentucky! Now, don't sleep on these guys. They are serious competitors. Although some of the teams need a little practice. Or a lot of practice -- I mean, she's hitting every cone! You're supposed to go between them, not through them. The announcer claims it's a steering problem. Naw, it's not a steering problem. The winning team crushed the competition by more than 2 seconds.

Goodbye

AZUZ: But they took it all in stride. Afterwards, we hear they were as cool as the other side of the pillow. You know, if we ever got tired of this stuff, we'd go ahead and put the puns to bed. But what kind of a wet blanket would want that? They just keep on coming. I some of you out there are groaning, and it's probably time that we quit while we're a-bed. We'll have more tomorrow for you. For CNN Student News, I'm Carl Azuz.
