I fell in love with science as founding editor of Scholastic's SuperScience magazine (1988-91). I'm versed in and comfortable about creating content and games in ALL the STEM topics.

Alice Field is an aspiring game designer and animator, an only child, who grew up traveling the world with her parents and sharing her adventures online.

I adopted the voice of Alice on Everloop (a social media site for tweens), writing digital journals, activities, games, and a steady stream of live, real-time posts.

I conceived, proposed, and created five interactive travel journals, told in the voice of Alice as she travels to Indonesia and Japan during her Gap Year.

In Episode 6: The Last Gas Station, I joined the creative team as narrative designer.


I'm a writer and narrative designer of video games, developing character profiles and back stories, designing the narrative arc and interactives, and integrating story with game play.


Throughout his life, Chief Joseph of the Wallowa band of Nez Perce struggled to keep his people's land in northeastern Oregon and to solve conflicts with white settlers.

His skillful efforts failed when the government allowed the white murderers of his friend to go free and soldiers ordered the entire Nez Perce population to move to a tiny reservation. A handful of vengeful warriors murdered 18 settlers, sparking the War of 1877.

To avoid bloodshed and certain defeat against a powerful force, more than 700 Nez Perce men, women, and children—many of them elderly and wounded—traveled 1,500 miles across several states, pursued by five units of U.S. soldiers.

Chief Joseph is best known for the famous vow, "From where the sun now stands, I will fight no more forever."

Read his tragic story in my children's biography Chief Joseph: The Voice for Peace.


Forensic anthropologist Diane France is a scientist who's leading a life of crime. That is, she's a bone detective who solves murder mysteries (and other mysteries) by finding and identifying human skeletons.

In her Colorado lab and traveling around the world, she has also "met" the bones of famous people in history, from Russian royalty to American outlaws and Civil War soldiers. Click on the title for more details.


Adriana Ocampo is a planetary geologist who has worked for NASA, the U.S. space agency, since she was a teenager. Her story begins in South America, where she grew up, but a passion for rocks and craters has led her all around the world. She explores Earth's past on foot, by leading field expeditions to seek out rocks that were blasted, melted, vaporized, and otherwise tortured by the explosive crash of an asteroid or comet.

Meanwhile, she investigates the fascinating features of Mars, Jupiter, and other planets through the electronic eyes of NASA's robotic spacecraft.


I've been teaching English to immigrants for more than a decade and developed Letter Perfect English as a simple but flexible teaching tool. My learners have played 100 games and activities with this unique picture card deck, for beginners to advanced students, suited for use with teens and adults. The games develop vocabulary, speaking, listening, grammar, storytelling, and writing skills.


Crime Scene Investigation (ages 9 to 14, Lexile level 690, Accelerated Reader Quiz #112861) is the true story of the science, technology, and thinking skills behind collecting evidence at a crime scene. The book features interviews with crime scene investigators and real crime cases, including an art theft report that young sleuths can read for clues to "who dunnit."

Autopsies/The Body as Evidence (ages 9 to 14, Lexile level 690, Accelerated Reader Quiz #112860) explores how medical examiners treat corpses like a crime scene--searching every bit, inside and out, for evidence of how and when the person died. The last chapter features excerpts from an actual autopsy report and challenges readers to apply what they've learned to uncover a "smoking gun" clue to a murder.

Review by Booklist:
Young CSI fans will be engrossed by this title in the Crime Scene Science series. The well-balanced mix of case studies, scientific explanations, and descriptions of fieldwork offers a dynamic, behind-the-scenes look at crime-scene investigations. Hopping doesn't sensationalize; she focuses on facts: "a rotting corpse releases about 400 chemicals into the air." Even so, the graphic details and color photos may disturb some young people. A resource section of books and Web sites encourages further exploration.
