- Bonus Halloween Mystery | Pumpkin Patch
Belinda and Madison are sure their witch jack-o-lantern will win their neighborhood pumpkin-carving contest. They’ve even covered all the openings with construction paper so the light will glow green. But when they come back from trick-or-treating, their candle has blown out…again! Halloween Bonus Mystery Selected from: One Minute Mysteries: 65 Short Mysteries You Solve With Science! Pumpkin Patch "Where's Linus? We have the Great Pumpkin," Belinda said. Madison laughed. It was Halloween, and all the neighbors around the cul-de-sac were in a contest to see who carved the best pumpkin. The prize was a gift certificate to the video store. She and Belinda had carved a pumpkin with the face of a witch and then used colored paper to cover the openings so that the light from the candle inside would make the face glow green. They lit the candle, put the top back on the pumpkin, and went out trick-or-treating. As they went from house to house, they looked over the other entries for the contest. Carly had done a nice carving of a ghost, and Peter had used an odd-shaped pumpkin to make a funny-looking frog. They came to Sam's house just as he was setting out his pumpkin. "This is the winner right here," Sam said, in a not-too-friendly voice. Madison had to admit, he'd done a good job of carving a haunted house, but she still knew her and Belinda's pumpkin was better. "Watch out for him," Belinda said, as they went to the next house. "He'll probably smash the other pumpkins just so he can win." After they made a lap of the neighborhood, they returned to Madison's house to drop off the candy before everyone would meet for the winner to be announced. Their pumpkin was not smashed, but the candle was out, so it didn't look like anything special. "I know who's to blame," said Madison. "Who?" Belinda asked. REVEAL ANSWER

March Selected from: One Minute Mysteries: 65 MORE Short Mysteries You Solve With Science! Think Green, Guys! Pranav and Maneet’s family had decided to buy a house in a new development. There were several models to pick from and they had chosen one with the features they wanted. Two houses of that model were finished and for sale. Their backs faced each other, one house looking north and the other looking south—each with a big, open lawn in front. There were tall trees between them, coming almost to the back of each house. “It’s hard to pick. These two houses are exactly the same,” their mother said, as they stood on the back deck of the house that faced north. “The price is the same, too, although either way we’re going to have to watch our money more closely after buying a new house,” said their father. Pranav could feel warmth in the sunlight, even through the bare branches of the trees. Spring was coming. Where they lived, winter was short and mild, and furnaces ran only a little while. Summer was long and hot—air conditioners ran almost all day. “We should buy this one,” Pranav said, after thinking for a moment. “What did you do? Flip a coin in your head?” Maneet asked.

Había llovido todo el día y la noche anterior, pero esta mañana solo estaba fresco y nublado mientras los niños caminaban hacia el Centro de Visitantes. La clase estaba estudiando distintos ecosistemas, y había tomado un autobús a un parque con un prado, un estanque y bosques. Estaban divididos en tres grupos para buscar muestras y tomar fotos. Tenían radio-teléfonos para mantenerse en contacto, porque los teléfonos celulares no funcionaban allí. Un grupo tomó un sendero largo y empinado para llegar al Estanque del Sapo con el Sr. Wysor. El grupo de Marcel y Tucker cruzó hacia la pradera con la Sra. Smith, mientras que el tercer grupo se encargó de estudiar el bosque en una ladera con la Sra. Hammerick. Después de más o menos una hora, el grupo de la Sra. Smith había terminado. Regresó al Centro de Visitantes, pero ninguno de los otros grupos había regresado. La Sra. Smith le pidió a Marcel que verificara cómo estaban los demás. —Terminamos en el prado y podemos irnos en cualquier momento. ¿Cómo están ustedes? Cambio —dijo por el radio-teléfono. —Tenemos nuestras muestras y estamos tomando las últimas fotos. Caminaremos de regreso en un par de minutos. Cambio- —respondió una voz. —Estamos tomando muestras, pero hay tanta neblina aquí que las fotos no saldrán. Dennos otros 20 minutos. Tal vez la niebla se levante.

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
