15 places kids should see by age 15

15 places kids should see by age 15

(Budget Travel) -- It took us hours of heated debate, weeks of research, and years of experience to whittle down America's monuments to a definitive list of 15 musts for anyone under 15. Not only are these attractions fun and (shhhh) educational, they're especially magical through the eyes of a child.

Two years ago, Budget Travel picked 15 American landmarks every kid should see, from Ellis Island to Redwood National Park. The new and improved 2011 lineup takes that challenge even further, by highlighting how our country's top sights cater to kids' abbreviated attention spans. From roasting marshmallows around a campfire to playing dress-up at Monticello, these cool, interactive activities ensure that the younger set will enjoy these must-see spots as much as their parents do.

Budget Travel: See the 15 destinations

Grand Canyon - Arizona
During the day, stroll the 4-year-old Skywalk, a U-shaped, glass-bottom observation deck that juts 70 feet over the canyon's West Rim and sits 4,000 feet above the Colorado River. Come sunset, hit Grand Canyon Apache Stables, where, for $25.50 per person, you can hitch a one-hour ride on a horse-drawn wagon that ends around a campfire. Tip: BYO marshmallows and hot dogs so you can cook up a nighttime snack. Skywalk Package including mandatory Legacy pass. Kids 3--11, $57.49; Adults, $73. grandcanyonskywalk.com Grand Canyon Apache Stables: $25.50, kids 8 and up, apachestables.com/

Redwood National Park - California
Ancient, sky-high sequoias aren't the only attraction in this lush California locale -- there's cool aquatic life, too. Take a guided tide pool tour, where budding biologists can scramble between the coastal forest's rocks while hunting for underwater creatures such as orange and purple ochre sea stars and sprawling, green anemones. Free tide pool tours are offered during the summer through Redwood National Park; check website for exact schedule. nps.gov

Monticello - Virginia
The dreaded "look but don't touch" rule means nothing at the Griffin Discovery Room, which opened on the grounds of Thomas Jefferson's Monticello estate in 2009. Nothing is off-limits in the space, which features replicas of the third president's possessions, from his alcove bed to his polygraph machine. Even his closet is fair game: Kids can try on clothes modeled after his 18th-century wardrobe. The Griffin Discovery Room is part of Monticello's House and Grounds tour. Adults, $17 (low season), $22 (high season); Kids 6-11, $8 (year-round). monticello.org

Budget Travel: The world's newest natural wonders

The Freedom Trail - Massachusetts
Who needs a social studies book when you can learn about Colonial history from an 18th-century ship captain while parading around Boston's waterfront? The 90-minute Pirates and Patriots tour, led by an actor in 1770s naval garb, focuses on maritime history and introduces the scrappy, ship-raiding characters that inhabited the city's North End during the Revolutionary era.

Stops include the aptly named Long Wharf, once the longest in the world and the epicenter of Boston's colonial shipping industry, and Griffin's Wharf, site of the 1773 Boston Tea Party. Bonus: Some tour guides are known to hand out vintage goodies, so you might walk away with a fistful of colonial money or musket balls. The Freedom Trail's Pirates & Patriots Tour runs from June to Nov. Adults, $12; kids 6--12, $7. thefreedomtrail.org

Niagara Falls - New York
Sure, your grandparents honeymooned there, but the majestic waterfalls straddling the U.S.-Canada border are worth a 21st-century trip. Ever wonder what it's like to be a rubber ducky in a massive bathtub? Sign up for the Cave of the Winds tour, which begins after you change into a complimentary yellow poncho and sandals (trust us, you'll need 'em).

After riding an elevator 175 feet down into the Niagara Gorge, you'll stand on the Hurricane Deck, where you'll be drenched by the tropical-storm-like spray from the 181-foot Bridal Veil Falls, where the water falls at a rate of up to 68 mph. Cave of the Winds operates May 1--Oct. 25. Adults, $11; kids 6--12, $8; 5 and under, free. niagarafallsstatepark.com

The National Mall - Washington, D.C.
Riding the streets of Washington, D.C., in a boat on wheels might sound cheesy, but cruising the Potomac River in one is pretty sweet. Set in a WWII-era amphibious vehicle, the 90-minute D.C. duck tour covers both land and sea.

The first leg hits the history-packed National Mall -- look for the 19-foot-tall Lincoln Memorial, the Capitol building, and the Smithsonian museums -- and then switches to a scenic river trip. Highlight: The boat pauses at Gravelly Point, a park located just a few hundred feet from the runway at D.C.'s Reagan National Airport, so you can watch roaring planes take off and land. D.C. duck tours cost $31.50 for adults, and $16.20 for kids 11 and under. trustedtours.com

Williamsburg - Virginia
Everyone in this living-history site likes to play dress-up, and visitors are no exception. At the Great Hopes Plantation -- a re-creation of the town's original 1700s farm -- a stash of old-timey accessories await, from tricorne (three-pointed) hats for boys and shifts and mop caps (bonnets) for girls.

The costumes come in handy in the field, where kids can perform 18th-century household chores, such as picking bugs off potato crops, fetching water from the well, or hoeing the soil, that are likely to make clearing the dinner dishes seem like a breeze by comparison. Great Hopes Plantation can be accessed through regular admission tickets. Spring prices: adults, $37.95; kids 6--17, $18.95; 5 and under, free. history.org

Walt Disney World Resort - Florida
Taking a family vacation to the world's largest, most popular theme park is a no-brainer, and just-opened exhibits give even more reasons to visit Mickey & Co. Our pick: the Wild Africa Trek, a private, three-hour safari featuring live Nile crocs, statuesque giraffes, and lazy hippos.

Strap into a harness and you can even dangle 10 feet above the crocodiles' heads. (The attraction is open to kids 8 and up.) Mid-jungle trek, the safari car (imagine an open-air Jeep that allows for standing) will stop on the trail for a traditional African lunch. Wild Africa Treks begin at $189 per person, including lunch, but not including admission to Disney's Animal Kingdom. disneyworld.disney.go.com

Independence Hall - Pennsylvania
Acquaint yourself with the spirits of America's founding fathers on Philadelphia's Ghost Tour, a 90-minute, candle-lit stroll that winds past landmarks like Independence Hall, where the Constitution was adopted; the Powel House, which hosted George and Martha Washington's 20th wedding anniversary celebration; and the 238-year-old City Tavern, John Adams's former watering hole.

A cape-wearing, lantern-carrying guide points out "haunted" graveyards (St. Peter's Cemetery) and reports sightings of Benjamin Franklin, who's said to roam the city's streets. The best part: All the ghost stories are based on documented accounts, which makes them all the more spooky.Ghost Tour of Philadelphia, adults, $17; kids 4 and up, $8. ghosttour.com

Budget Travel: Tourist traps you love

Alcatraz Island - California
Shiv collections and cramped jail cells don't exactly sound kid-friendly, but they offer a glimpse into America's most notorious island prison -- and the National Park Service is all for bringing younger ones for a visit. Hop a ferry from San Francisco's Pier 33 and stroll the damp, gray halls of the maximum-security pen, which housed criminals like Al Capone and George "Machine Gun" Kelly from 1934 to 1963. (You can even get behind bars in one of the cells, if you dare.)

Don't miss the audio tour, which was updated in 2007 when former inmates and guards recorded their memories of doing time at "the Rock." If you're feeling brave, take the night tour, which lets you roam the prison after dark. Alcatraz Cruises is the official carrier for tours to Alcatraz Island. Adults 12--61, $26; kids 5--11, $16, 4 and under, free. alcatrazcruises.com

Ellis Island - New York
Between 1892 and 1924, more than 17 million immigrants passed through Ellis Island; today, their descendants account for 40% of Americans. Go on a hunt for your ancestors at the Ellis Island Immigration Museum, where for $5 you can search through millions of records to find the exact date your relatives sailed into the Port of New York, as well as which ship they were on and whether they traveled with other family members. (Bonus: copies of the documents are yours to keep.)

And don't miss the construction of the Peopling of America Center, which cost $20 million to build and is slated to open in 2012. The new space focuses on U.S. immigration from 1955 (when Ellis Island closed) to the present, and houses interactive multimedia exhibits, like a touch screen that reflects demographic changes in American cities over time. Ellis Island admission prices as of March 18: adults, $37.95; children, $18.95; children under 5, free. ellisisland.org

Yellowstone National Park - Wyoming, Montana and Idaho
Snag a Young Scientist Toolkit stocked with magnifying glasses, rock samples, and stopwatches to time geyser eruptions at the Old Faithful Visitor Center and hit the great outdoors for some investigating. The coolest toy: an infrared-thermometer gun that takes readings of thermal pools when pointed at the water. And there's lots of H20: The 3,472-square-mile park is home to more geothermal features (geysers, hot springs, mud spots) than any place on earth. The Young Scientist activity booklet and toolkit costs $5 (toolkit must be returned after use). Park entrance fee starts at $12.nps.gov

Budget Travel: Best secret hotels of the world

Fenway Park - Massachusetts
Even die-hard Yankees fans have to admit that visiting Major League Baseball's oldest stadium is an exercise in Americanism: Babe Ruth pitched there! Ted Williams hit a 502-foot home run! Boston's Fenway turns 100 next year, but its features are still intact. Check them out for yourself on a guided 50-minute tour, where hands-on exploration is encouraged: You can touch the Green Monster (the park's 37-foot-tall left-field wall), peek into the dugout, poke around inside the press box, and even walk across the baseball diamond, depending on how friendly the grounds crew is feeling that day. Fenway Park tours, adults, $12; kids 3--15, $10; seniors, $11. mlb.mlb.com

Craters of the Moon National Monument & Preserve - Idaho
The National Park Service calls this Idaho preserve "the only officially weird park" in the country. And for good reason: The jagged, black landscape -- formed by volcanic eruptions up to 15,000 years ago -- boasts a 618-square-mile lava field, the biggest in the U.S. (The rocky surface is so moonlike that Apollo 14 astronauts trained at the site in 1969.) The park's most awe-inspiring feature is its lava tubes, underground passageways created by hardened molten rock.

Grab a flashlight and head to Indian Tunnel, which, at 30 feet high and 50 feet wide, allows for comfortable exploring. Craving an even more intense experience? Exit the cave at the far end, a feat that requires mounting a big rock pile and squeezing through a small opening. Park entrance fee is $8 per vehicle; bike or foot entrance starts at $4; age 14 below is free. nps.gov

Budget Travel: 11 places you want to be right now

San Diego Zoo - California
With more than 4,000 rare and endangered animals representing 800-plus species and subspecies, the San Diego Zoo is one of the most diverse in America. But its coolest attraction -- literally -- is the Polar Bear Plunge, which reopened last March after a $1 million makeover.

Aside from permanent polar residents Kalluk, Chinook, and Tatqiq, new features include a snow den you can burrow into (the snug space mimics where female bears birth their cubs); a helicopter used on actual Arctic explorations that invites climbers into the cockpit; and the Experience Wall, where zookeepers open the glass panels surrounding the bears' habitat, letting them sniff at visitors through wire mesh. Ages 12 and up, $40; 3--11, $30. sandiegozoo.org

Rethinking Preschool

DOUBLEX

Why Preschool Shouldn't Be Like School

New research shows that teaching kids more and more, at ever-younger ages, may backfire.

By Alison Gopnik

Ours is an age of pedagogy. Anxious parents instruct their children more and more, at younger and younger ages, until they're reading books to babies in the womb. They pressure teachers to make kindergartens and nurseries more like schools. So does the law—the 2001 No Child Left Behind Act explicitly urged more direct instruction in federally funded preschools.

There are skeptics, of course, including some parents, many preschool teachers, and even a few policy-makers. Shouldn't very young children be allowed to explore, inquire, play, and discover, they ask? Perhaps direct instruction can help children learn specific facts and skills, but what about curiosity and creativity—abilities that are even more important for learning in the long run? Two forthcoming studies in the journal Cognitionone from a lab at MIT and one from my lab at UC-Berkeley—suggest that the doubters are on to something. While learning from a teacher may help children get to a specific answer more quickly, it also makes them less likely to discover new information about a problem and to create a new and unexpected solution.

What do we already know about how teaching affects learning? Not as much as we would like, unfortunately, because it is a very difficult thing to study. You might try to compare different kinds of schools. But the children and the teachers at a Marin County preschool that encourages exploration will be very different from the children and teachers in a direct instruction program in South Side Chicago. And almost any new program with enthusiastic teachers will have good effects, at least to begin with, regardless of content. So comparisons are difficult. Besides, how do you measure learning, anyway? Almost by definition, directed teaching will make children do better on standardized tests, which the government uses to evaluate school performance. Curiosity and creativity are harder to measure.

Developmental scientists like me explore the basic science of learning by designing controlled experiments. We might start by saying: Suppose we gave a group of 4-year-olds exactly the same problems and only varied on whether we taught them directly or encouraged them to figure it out for themselves? Would they learn different things and develop different solutions? The two new studies in Cognition are the first to systematically show that they would.

In the first study, MIT professor Laura Schulz, her graduate student Elizabeth Bonawitz, and their colleagues looked at how 4-year-olds learned about a new toy with four tubes. Each tube could do something interesting: If you pulled on one tube it squeaked, if you looked inside another tube you found a hidden mirror, and so on. For one group of children, the experimenter said: "I just found this toy!" As she brought out the toy, she pulled the first tube, as if by accident, and it squeaked. She acted surprised ("Huh! Did you see that? Let me try to do that!") and pulled the tube again to make it squeak a second time. With the other children, the experimenter acted more like a teacher. She said, "I'm going to show you how my toy works. Watch this!" and deliberately made the tube squeak. Then she left both groups of children alone to play with the toy.

All of the children pulled the first tube to make it squeak. The question was whether they would also learn about the other things the toy could do. The children from the first group played with the toy longer and discovered more of its "hidden" features than those in the second group. In other words, direct instruction made the children less curious and less likely to discover new information.

Does direct teaching also make children less likely to draw new conclusions—or, put another way, does it make them less creative? To answer this question, Daphna Buchsbaum, Tom Griffiths, Patrick Shafto, and I gave another group of 4-year-old children a new toy.* This time, though, we demonstrated sequences of three actions on the toy, some of which caused the toy to play music, some of which did not. For example, Daphna might start by squishing the toy, then pressing a pad on its top, then pulling a ring on its side, at which point the toy would play music. Then she might try a different series of three actions, and it would play music again. Not every sequence she demonstrated worked, however: Only the ones that ended with the same two actions made the music play. After showing the children five successful sequences interspersed with four unsuccessful ones, she gave them the toy and told them to "make it go."

Daphna ran through the same nine sequences with all the children, but with one group, she acted as if she were clueless about the toy. ("Wow, look at this toy. I wonder how it works? Let's try this," she said.) With the other group, she acted like a teacher. ("Here's how my toy works.") When she acted clueless, many of the children figured out the most intelligent way of getting the toy to play music (performing just the two key actions, something Daphna had not demonstrated). But when Daphna acted like a teacher, the children imitated her exactly, rather than discovering the more intelligent and more novel two-action solution.

As so often happens in science, two studies from different labs, using different techniques, have simultaneously produced strikingly similar results. They provide scientific support for the intuitions many teachers have had all along: Direct instruction really can limit young children's learning. Teaching is a very effective way to get children to learn something specific—this tube squeaks, say, or a squish then a press then a pull causes the music to play. But it also makes children less likely to discover unexpected information and to draw unexpected conclusions.

Why might children behave this way? Adults often assume that most learning is the result of teaching and that exploratory, spontaneous learning is unusual. But actually, spontaneous learning is more fundamental. It's this kind of learning, in fact, that allows kids to learn from teachers in the first place. Patrick Shafto, a machine-learning specialist at the University of Louisville and a co-author of both these studies; Noah Goodman at Stanford; and their colleagues have explored how we could design computers that learn about the world as effectively as young children do. It's this work that inspired these experiments.

These experts in machine learning argue that learning from teachers first requires you to learn about teachers. For example, if you know how teachers work, you tend to assume that they are trying to be informative. When the teacher in the tube-toy experiment doesn't go looking for hidden features inside the tubes, the learner unconsciously thinks: "She's a teacher. If there were something interesting in there, she would have showed it to me." These assumptions lead children to narrow in, and to consider just the specific information a teacher provides. Without a teacher present, children look for a much wider range of information and consider a greater range of options.

Knowing what to expect from a teacher is a really good thing, of course: It lets you get the right answers more quickly than you would otherwise. Indeed, these studies show that 4-year-olds understand how teaching works and can learn from teachers. But there is an intrinsic trade-off between that kind of learning and the more wide-ranging learning that is so natural for young children. Knowing this, it's more important than ever to give children's remarkable, spontaneous learning abilities free rein. That means a rich, stable, and safe world, with affectionate and supportive grown-ups, and lots of opportunities for exploration and play. Not school for babies.
