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.

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

Guardián del césped —Papá, realmente necesitamos una nueva podadora de césped —dijo Murphy. De todas las personas, Murphy es quien más sabría al respecto. Desde que había cumplido los doce años, le correspondía podar el césped todos los sábados por la mañana. La norma familiar era que los quehaceres se tenían que completar antes de cualquier diversión. Murphy lo había hecho tantas veces, que sabía el número exacto de veces que tenía que ir y venir por el jardín: 20 veces en cada dirección. El padre le echó un vistazo a la podadora. Era difícil de encender y cortaba el pasto a alturas desiguales, dejando partes del césped desnivelado. —Tienes razón. Vayamos a la tienda a ver qué opciones hay —dijo. En la tienda, el padre de Murphy señaló una podadora y dijo: —Este es el modelo más reciente de la podadora que tenemos, con la misma navaja de 60 centímetros de ancho —dijo—. Y aquí hay una con una navaja de 75 centímetros. El hermano menor de Murphy, Hugh, que los había acompañado a la tienda, agregó: —Aquí hay una con una cuchilla de 60 centímetros, pero es de las que tritura el césped como abono. Dice que la navaja gira un 20% más rápido. —Creo que deberíamos comprar la que me permita terminar el patio en tan solo 4/5 del tiempo que me toma hacerlo ahora —dijo Murphy. —¿Cuál es esa? —preguntó Hugh.

It's a wonderful addition that brings diversity to children's literature, inspiring the next generation to appreciate and protect our natural world." - Grant Ballard , Ph.D., Chief Science Officer, Point Blue "In Tiny Tern Takes Flight, Donna B. McKinney invites readers into Tiny Tern and their flock’s enchanting migration journey. With Fiona Osbaldstone’s vibrant illustrations, this delightful tale sparks imagination and fosters a love for nature in young readers.” – S. Cargill , @shontalthebirder “The best children’s books should be familiar enough to be relatable – and mysterious enough to be intriguing. ‘Tiny Tern Takes Flight’ achieves both of these by telling the story of the Artic Tern - one of the world’s most itinerate travelers – who ventures from pole to pole annually in search of sun and food. Avian migration is truly one of the world’s most intriguing natural phenomena - this story can only help engage future naturalists and ornithologists.” – Dick Evans , San Francisco-based Documentary Photographer, Birder and author About the Author About the Illustrator Donna B. McKinney lived most of her life in the Washington, D.C. area, where she worked at the U.S. Naval Research Laboratory, writing about science. Now she has another great job—writing books for kids, including her previous release titled Lights On. Donna currently lives in North Carolina with two full-of-mischief dogs. When she’s not writing, she enjoys hiking, fishing, and playing a game called pickleball (kind of like a mix of tennis and ping pong). Born and bred in Kent, England, Fiona Osbaldstone loved painting as a kid and used to paint her own versions of Disney characters. She always wanted to do something with art and went to the Kent Institute of Art & Design. She was inspired by the works of David Shepherd and Norman Rockwell for their detail and diversely different styles. Her work includes natural history, botanicals, people, and scenes. Outside of the artistic field, although not too far removed, she loves pottery and makes and sells her own pieces. She enjoys photography as well as cycling but is “not too good at that and will invariably end up in a ditch.”

Hallando la solución La primavera había llegado y las gemelas Frances y Fiona estaban contentas de que podrían empezar a pasar tiempo afuera en su jardín. El jardín de la familia estaba cubierto por árboles con ramas largas; el sitio perfecto para el pasatiempo de las gemelas de avistar aves. Frances tenía la labor de mezclar azúcar con agua para el bebedero de los colibríes. En el pasado, las niñas habían notado que mientras más dulce preparaban el almíbar, más colibríes venían. Este año Frances había decidido hacer la mezcla lo más dulce posible. En la cocina, agregó el azúcar al agua caliente hasta que el azúcar empezó al acumularse al fondo de la hoya aun cuando revolvía el agua. Luego llenó el bebedero de los pájaros con la solución de agua. —¡Me encanta cuando vemos muchos colibríes! —exclamó Frances, tapando el bebedero. Las niñas colgaron el bebedero de una rama que podían observar desde su terraza. Pasaron varios días antes de que empezaran a aparecer los colibríes, y cuando por fin llegaban, se iban casi al instante. Las niñas fueron a revisar el bebedero. —Creo que veo el problema —dijo Fiona, raspando polvo de los hoyos en el bebedero. —¿De dónde salió eso? —preguntó Frances. —Los pájaros no pueden sacar la mezcla del bebedero —dijo Fiona—. Este polvo que está obstruyendo las aperturas en el bebedero es azúcar. —Pero yo no puse azúcar en la parte de afuera —protestó Frances—. Y dejé de agregarle azúcar al agua cuando se empezó a acumular en el fondo mientras la revolvía. Sé que cuando el agua ya no aguanta más azúcar, está saturada y no puede disolver más. ¿No es cierto?

Halloween Hippie "Hey, I have an old picture of my grandma looking just like that, only it wasn't a costume to her," Kassandra said as Ingrid walked into the homeroom. "She said they actually thought they looked cool." Their school normally had a dress code, but it was Halloween and everyone had come in wearing costumes. Ingrid was dressed like a hippie. She had a tie-dyed shirt, beads, sandals, and sunglasses with orange lenses shaped like hearts. Ingrid took off the sunglasses for class, but put them back on in the afternoon when it was time to get ready for the Halloween party. The class was decorating the classroom and painting signs for the school parade. Quan, who though he was funny, was hanging decorations upside down. Preston was pretending to sword fight in his pirate costume with a paint brush, and Ricky was playing with fake blood after putting some on his zombie costume. When it was almost time for the parade, Kassandra noticed that one of the signs had been decorated with a red, rather than orange, pumpkin. "Okay, who's the joker here?" Kassandra asked. She looked around the room for a guilty face. REVEAL ANSWER

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
