Experience 'Talking Science': A Children's Book Uncovering the Universal Language of Science and How Common Measurements Unify the World. A cozy hug is one meter wide, a good night’s sleep is 41,400 seconds long, and an African elephant weighs almost 5,500 kilograms. No matter where you are in the world, scientists use these same units of measurement to communicate with one another. Talking Science brings science vocabulary to life for even the youngest children. Written by award-winning children’s book author Mary Wissinger, with inviting and fun illustrations by Lilia Miceli, this innovative children’s book uses kid-friendly examples to show readers how big ideas can be shared—and how science connects us all. The International System of Units is a group of seven measurements—seconds, meters, kilograms, amperes, kelvins, moles, and candelas—that allow scientists anywhere in the world to understand each other. With this system, people from different places, who speak different languages, can describe and solve the same problems. In the past, scientists measured things in all kinds of different ways. But it's difficult to share science across the globe when one person uses their arm and another person uses their foot to measure the same thing! Now, using the universal language of science, we can work together to make discoveries. .

Un aventón La escuela de Jada y Michelle estaba cerrada por ser un día de capacitación de maestros, por lo que sus padres decidieron tomarse un día libre del trabajo para llevar a la familia a esquiar. Se alegraron al llegar, al ver que no había colas para montarse en los telesillas. Las dos niñas esquiaban bien, por lo que se dirigieron a la zona de la montaña con los senderos de diamantes negros, los más difíciles. Tres diferentes telesillas arrancaban del mismo sitio y subían la montaña hasta un sitio en la cima que conducía a varios senderos diferentes. —Tratemos de hacer el mayor número de recorridos —dijo Jada. Se fijaron en un rótulo para decidir cuál de los telesillas debían utilizar. La Caída en Picada tenía asientos para cuatro y capacidad para 1,200 esquiadores por hora. La Agárrate el Gorro tenía asientos para dos, y capacidad para 800 esquiadores por hora. Y la Acantilados Blancos tenía asientos para tres y capacidad para 900 esquiadores por hora. El letrero indicaba que cada telesilla tenía la misma cantidad total de sillas. —¿A dónde crees que deberíamos ir? —preguntó Michelle. REVELAR RESPUESTA

Little does Mara know, flying insects, digging worms, hungry birds, noisy neighbors, and other secret gardeners are working to help transform the lot into something even more beautiful than she imagined. Rain storms wash away seeds, but rabbits leave some behind. Some helpers nibble up weeds, and others fertilize the soil. Each time Mara visits the garden, she’s expecting to see her sunflowers growing. But as the flowers blossom, she uncovers the exciting secrets waiting for her! Mara Plants a Seed inspires young readers to develop a deeper connection to the environment around them and study the many ways natural processes and ordinary animals help plants grow and thrive.

'Mara Plants a Seed' is a perfect story to share with young readers that is packed with valuable lessons." - Melissa Inferrera, 1st Grade Teacher and Plant Mom, @musicmindandsoul “This precious tale of a girl’s journey into the garden inspires us to take a look around and imagine the possibilities. People, insects, bugs and even beings one can not see all come together in harmony. Powered by hope, tenacity and the help of community, we see how magical a single seed can be!” - Tamara Elmore, Tam in the Garden @taminthegarden "A once barren and neglected lot is transformed into a gorgeous, natural garden full of life, though Mara keeps an eye out for those sunflowers she's planted. She's not at all disappointed and neither was I! We're treated to a delightful, vertical two-page spread that I couldn't help but smile wide for when I turned to it. Bailey does a fantastic job of conveying how utterly wonderful it is to behold a wild garden, and Napoli and Furrow do an equally excellent job of explaining the process of seed to flower (including a blurb in the back encouraging readers to plant their own seeds)." - Goodreads Reviewer , Charessa "The principles of seed growth are entwined into this simple story leading to further discussions in the classroom about plant needs, ecosystems as well as ways to turn the unattractive and unused into something beautiful and well-loved." - Primary Teacher, Melanie Dulaney "Mara Plants A Seed is a lovely, heartfelt, relatable, lesson-filled, and creative story! This book is absolutely charming! Mara is a precious character. With her little act of kindness a trashed vacant lot begins to flourish. Her patience, love, and kindness helps nature become activated. The reader sees all the intentional, natural, and accidental actions which help the lot turn into a garden.

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 thought 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
