![]() Then they can swing over to the Mesozoic era to compare their data to the levels found on Earth during the period of dinosaur extinction. For example, they can travel to the Paleozoic era, the period when land plants first appeared-and dial-up the levels of oxygen, temperature, and solar radiation that existed during that time. They can also explore the five mass extinctions that happened on Earth, and view the planet’s corresponding drops in biodiversity. The app’s timeline allows users to visit Earth at any point during its development. The ability to manipulate the globe and zoom to any location, eon, era, or period.Location tracking of modern cities back over 500 million years.Climate and carbon dioxide data for the last 100 years.In-depth features on major geological and biological events in Earth history.Continental reconstructions dating back 4.5 billion years.“The college and high school educators, as well as the geology researchers who've seen the beta version of EarthViewer, can't wait to get their hands on it,” he said. ![]() His team previewed the app with teachers and professors during its development phase, and received a very positive response. Liu said that interactive computer-based simulations are being developed and used with growing frequency in many science-education disciplines. Scientific concepts can be more fully appreciated when students are given a chance to explore the Earth in such a visual way,” said Dennis Liu, Ph.D., Director of Educational Resources at HHMI. “We're very interested in how the app can be used in formal education. It combines visual analysis with hard data, and helps students make connections between geological and biological change.ĭownload the HHMI EarthViewer app from the App Store. The app, developed by HHMI’s BioInteractive team, tracks the planet’s continental shifts, compares changes in climate as far back as the planet’s origin, and explores the Earth’s biodiversity over the last 540 million years. Have you ever wanted to go back in time to see what the Earth looked like 400 million years ago? You can with the EarthViewer, a free, interactive app designed for the iPad, that lets users explore the Earth’s history with the touch of a finger by scrolling through 4.5 billion years of geological evolution.
