How fast would you have to go to outrun Hawaii’s fastest lava? How big is Mauna Loa? How many football fields can fit across Kilauea caldera?

These questions are among those answered in Camp Google, a free, online summer camp launched by the California-based tech company last month to spark kids’ interest in science and math. The camp explores Hawai’i Volcanoes National Park in a 12-minute video hosted by science communicator Derek Muller titled "What will you find in the wild?"

"Technology gets bashed for keeping kids inside with their eyes glued to a screen," said Jessica Ferracane, spokeswoman for the Big Isle national park. "But technology can be a great portal to connecting kids with the outdoors. With Camp Google that’s certainly what we observed. It connects us to a lot of kids who might not have the opportunity to visit Hawai’i Volcanoes National Park."

For local families it offers ideas on how to make your next visit, whether virtual or in person, a potential math or science lesson.

Accompanied by breathtaking video of erupting volcanoes, park ranger Rebecca Carvalho, 24, of Volcano Village is charming in front of the camera introducing Mauna Loa as the world’s largest volcano and Kilauea as one of the world’s most active volcanoes. Carvalho explains some kid-friendly unique aspects of the park — from the legend of Pele to the vital role of the native ohia lehua tree.

The park is explored, from the Thurston Lava Tube to the lava lake in Halemaumau Crater and the 32-year-old Pu’u O’o eruption.

U.S. Geological Survey volcanologist Don Swanson explains the variety of samples he collects from the lava lakes, including lava bombs and Pele’s hair, the thin fibrous material that forms when liquid lava droplets fly through the air.

The camp content, created by Google engineers in partnership with the nonprofit Khan Academy, National Geographic Kids, NASA and the National Park Service, features four themes: oceans, space, nature and music. The exploration of Hawaii’s volcanoes is part of the nature component.

Kids can watch videos and try themed science activities at home, such as making crystals out of sugar, eggs and food coloring.

While the camp is geared toward ages 7 to 10, younger ones can participate with supervision. No registration or Google account is needed. After completing an activity, kids earn virtual badges. The program was launched July 13 but will remain online indefinitely. Participants can jump in anytime.

Chelsea Day, a mother of three boys, ages 4, 2, and 1, from Southern California, said her eldest liked it when Carvalho made noises illustrating the sounds volcanoes make. Day, who also writes a blog from a mother’s viewpoint, somedayilllearn.com, spent part of her childhood on Maui and is excited about taking the kids to the park one day.

"Being able to print and save the badges is cool," she said. "He has a folder for stuff like that which he is very proud of."

Mililani mom Nadia Kouchi, a lifestyle correspondent for the Hawaii Mom Blog, watched the Camp Google video with her son, Cade, 4, and said it was a nice introduction to volcanoes for him. Her third-grader daughter, Lauren, on the other hand, enjoyed the "Why does music make you move?" video because she loves dance.

She and her family have only been to the Kona side of Hawaii island, and never been to Hilo or Hawai’i Volcanoes National Park.

"We’re trying to find a time to go," she said.

The answers to those questions at the beginning of this article: You’d have to run 6 miles per hour to outrun fast-moving lava, although when funneled down a well-formed path, lava can reach up to 40 mph.

The 2,000 square miles of Mauna Loa make it almost 10 times bigger than Mount Everest. Forty-four football fields can fit across Kilauea’s more than 1-mile-diameter crater.
