Slow Boat “You guys will love this place,” Jesse’s grandfather said. “I go there all the time.” Jesse and his friend Thomas were visiting Jesse’s grandfather, who loved boating and had just bought a new boat. From Jesse’s grandfather’s house along a river, they would be going downstream to a park that had a fishing pier and a restaurant. “How far is it?” Thomas asked as they got on the boat. “20 nautical miles,” Jesse’s grandfather said. “A nautical mile is about 1/6 longer than a land mile, or almost 2 kilometers.” The boat’s speedometer showed the engine was running at 20 knots, which Jesse’s grandfather said meant 20 nautical miles per hour on the trip there, which lasted 48 minutes. They had a fun day, although they didn’t catch any fish. The speedometer showed the same speed on the trip back, which took 1 hour and 20 minutes. Thomas and Jesse climbed out onto the dock while Jesse’s grandfather tied up the boat. “Well, we learned something today,” Thomas said to Jesse. “You mean that we’re no good at fishing?” Jesse said. “Not that. If the distance was 20 nautical miles and the boat was moving at 20 knots, the ride should have taken 1 hour, but it didn’t—in either direction. Either the speedometer is wrong about the speed, or your grandfather is wrong about the distance,” Thomas said. “But which?” REVEAL ANSWER

The campers were sent off on all kinds of odd errands, such as finding animal fur, certain kinds of leaves, nuts, and other bits of nature. Dominic and Vincent had ended up with what they were sure was the toughest assignment: figuring out the exact height of the lone tree in the center of the field. They almost had to laugh when they were given only two tools to do it: a yardstick and a large ball of string. “This is impossible,” Dominic said, squinting up at the top of the tree. It was a sunny day. “It can’t be impossible,” Vincent said. “The counselor said that other guys have done it with the same things they gave us.” They thought for a while. “Well, I have an idea,” Dominic said, “but it’s not going to be easy. One of us could hold the ball of string while the other one ties the end to his belt and climbs the tree. We could probably get close enough to the top to estimate how much is left, and then we could add that to the length of string from there to the ground.” “I don’t think we’d like the result of that,” Vincent said. “Why not?” asked Dominic.

April Selected from: One Minute Mysteries: 65 More Short Mysteries You Solve With Science! Take a Hike The students were pleased with the weather on the day of their field trip. It had rained the previous day and night, but this morning it was only cool and cloudy as the kids walked to the Visitors’ Center. The class was learning about different ecosystems, and had taken a bus to a park with a meadow, a pond, and woods. They were divided into three groups to collect samples and take pictures. They had walkie-talkies to keep in touch because cell phones didn’t work there. One group walked down a long, steep path to Frog Pond with Mr. Wysor. Marcel and Tucker’s group hiked across to the meadow with Ms. Smith, while the third group took on the task of studying the woods on a hillside with Mrs. Hammerick. After an hour or so, Ms. Smith’s group was finished. They walked back to the Visitors’ Center, but neither of the other groups had returned. Ms. Smith asked Marcel to check on them. “We’re finished in the meadow and can leave any time. How are you guys doing? Over,” he said into the walkie-talkie. “We have our samples and are just taking the last of the pictures. We will start walking back in a couple of minutes. Over,” a voice replied. “We’re getting samples, but it’s so foggy here that the pictures won’t be any good. Give us another 20 minutes. Maybe the fog will lift. Over,” another voice responded. “I didn’t recognize those voices. Which group needs more time?” Tucker asked Marcel. REVEAL ANSWER

May Selected from: One Minute Mysteries: 65 MORE Short Mysteries You Solve With Science! Finding A Solution Spring had turned the corner and twins Frances and Fiona were pleased that they could start spending time outside in their backyard. The family's yard was sheltered by trees with long branches, perfect for the girls' hobby of bird watching. Frances had the job of mixing sugar in water for their hummingbird feeder. In the past, the girls noticed that more hummingbirds came to the feeder when they used a more sugary mix. This year Frances had decided to make the mix as sweet as possible. In the kitchen, she added sugar to hot water until sugar started collecting in the bottom of the pot even while she was stirring it. Then she filled the feeder with the water solution. "I just love it when we get to see so many hummingbirds!" Frances said as she screwed the lid onto the feeder. The girls hung the feeder on a tree branch where they could watch from their deck. It took a few days for the hummingbirds to start coming, and when they did, the birds left almost instantly each time. The girls went out to check the feeder. "I think I see the problem," Fiona said, scraping powder from the feeding holes. "Where did that come from?" Frances asked. "The birds can't get the mix out of the feeder," Fiona said. "This powder clogging the holes is sugar." "I didn't put any sugar on the outside," Frances protested. "And I stopped adding sugar to the water when the sugar started collecting at the bottom of the water even when I was stirring it. I know that when there's as much sugar as the water can hold, the water is saturated and can't dissolve any more sugar. Isn't that right?" REVEAL ANSWER

Home on the Range Guillermo and Fiorella’s family was enjoying their last hike of the fall before the weather turned too cold to go hiking. Halfway up a mountain on a trail they had never taken before, their father said, “This would be a great spot to have a house.” They looked around the edge of the sunny meadow, down to a stream, feeling a fresh breeze coming down the mountain. “You’re right, Dad,” Guillermo said. “I would love to live here, too,” said Fiorella. “It’s so pretty and I’m sure there are deer and all kinds of other animals here. It would be great to watch wildlife right from our front porch.” “I don’t know about living in a place like this,” their mother said. “There’s no electricity and you kids couldn’t live for more than a day without your gizmos. You could never get the power company to run an electrical line this far out into the woods.” “Well, if we were allowed to build a house here, we could make our own electricity,” Fiorella said. “But making electricity requires energy. Where would we get it?” their father asked. REVEAL ANSWER

Día de las brujas psicodélico —Oye, tengo una foto vieja de mi abuela vestida como tú, solo que ella no estaba disfrazada —dijo Kassandra cuando Ingrid entró al salón de clases—. Dijo que en su época creían verse muy bien. Normalmente su colegio tenía un código de vestimenta, pero era Halloween, el día de las brujas, y todos habían ido a la escuela disfrazados. Ingrid estaba vestida de hippie. Traía puesta una camisa de colores al batik, cuentas de colores, sandalias, y unas gafas con lentes color naranja en forma de corazones. Ingrid se quitó las gafas durante la clase, pero se las volvió a poner en la tarde a la hora de prepararse para la fiesta. Los alumnos estaban decorando el salón y pintando letreros para el desfile de la escuela. Quan, que pensaba que era muy chistoso, estaba colgando decoraciones al revés. Preston fingía que luchaba a espadas en su disfraz de piratas, y Ricky jugaba con sangre artificial después de ponerse un poco en su disfraz de zombi. Al acercarse la hora del desfile, Kassandra se dio cuenta de que uno de los letreros había sido decorado con una calabaza roja en vez de naranja. —¿A ver, quién es el chistoso? —preguntó Kassandra. Miró alrededor del salón en busca de una cara culpable. REVELA RESPUERTA
