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. The app allows students to see continents grow and shift as they scroll through billions of years – from molten mass to snowball Earth. Students can also explore changes in the Earth’s atmospheric composition, temperature, biodiversity, day length, and solar luminosity over its entire development. 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. So I was excited when I saw a press release from the Howard Hughes Medical Institute (HHMI) about a new resource: As we studied biomes, my students would annotate the maps with sticky notes and push pins for all to see. The map wall was one of the centers in my middle school classroom. Even though I have a GPS, I usually have a road map open, too. Whenever a conversation centered on a particular location, his response was “Let’s get out the map!” One of the chief roles in family outings was that of navigator with a road map (this was before the age of GPS devices in the car).Īs they say, nuts don’t fall far from the tree, so I’m a map nut, too. We could spend hours browsing through an atlas or USGS topographic maps.
