Dig into even more Thanksgiving projects with your friends and family!
Imagine: After months of treacherous sailing across the open ocean, skirting coral reefs and rocky shores, you alight upon lush tropical islands greeted by enticing aromas, unknown species, and a symphony of bird song…
Four years into her circumnavigation of the globe, the HMS Beagle carrying 24-year-old Charles Darwin landed in the Galápagos Islands forever changing our understanding of biodiversity and species evolution through natural selection. The Galápagos Islands are famous for their vast numbers of endangered and endemic species, rich biodiversity, and isolated Pacific location. Yet, invasive species and human development threaten their existence. Could exploring Darwin’s living laboratory be as simple as a virtual visit?
Research, as well as travel, in the Galápagos Islands is difficult due to its remote location and expense. In Darwin for a Day, a partnership between the Charles Darwin Foundation (CDF), Google Earth Outreach Team, Catlin Seaview Survey and the Galapagos National Park Directorate (GNPD), citizen scientists can virtually explore the best-preserved tropical archipelago in the world from the comfort of home.
Using innovative technology, Google Maps surveyed the Galápagos Islands and their marine environments in May 2013 to create a virtual, 360-degree experience that can be explored through the web. Grab your Darwin hat and moleskin as you select the island you wish to explore, zoom in to street view (much as you do when getting directions to your local pizza place or coffeeshop) then document the unique natural history by describing what you see – plant, animal, reptile, bird, fish. Just as real-life scientists record their data, observations can range from simple descriptions to detailed scientific names and technical information. Images and data are shared with CDF scientists and the iNaturalist community to help characterize the islands, monitor species diversity, and record changes to these delicate ecosystems.
“This is a unique opportunity to spearhead technology science for conservation and public awareness about the importance of the Galápagos ecosystems in a changing world.” according to Daniel Orellana, CDF’s head of Human Systems Research. “The outcomes of the project will allow CDF and GNPD to count on valuable information for research and the continued conservation of the Galápagos Islands.”
Since its launch in September 2013, Darwin for a Day has recorded nearly 600 observations of over 100 different species. As more citizen scientists participate, the data will be used to develop conservations strategies ranging for educational programs to responsible land management and ecotourism strategies without harming these unique ecosystems.
After feasting on turkey and pumpkin pie, why not make a date with Darwin for a Day and explore the exotic and far off wonders of the Galápagos Islands? The blue-footed booby and Galápagos sea lion send their thanks.
This project is also part of the United Nations Decade on Biodiversity 2011-2020.

Dr. Melinda T. Hough is a freelance science advocate and communicator. Her previous work has included a Mirzayan Science and Technology Graduate Policy Fellowship at the National Academy of Sciences (2012), co-development of several of the final science policy questions with ScienceDebate.org (2012), consulting on the development of the Seattle Science Festival EXPO day (2012), contributing photographer for JF Derry’s book “Darwin in Scotland” (2010) and outreach projects to numerous to count. Not content to stay stateside, Melinda received a B.S in Microbiology from the University of Washington (2001) before moving to Edinburgh, Scotland where she received a MSc (2002) and PhD (2008) from the University of Edinburgh trying to understand how antibiotics kill bacteria. Naturally curious, it is hard to tear Melinda away from science; but if you can, she might be found exploring, often behind the lens of her Nikon D80, training for two half-marathons, or plotting her next epic adventure.
The first time I ever saw the Perseids, I was 15 years old.
I snuck out of the house in the middle of the night (without telling my parents, of course) and found the darkest spot at the park nearby. What followed was one of the most awesome sights I had witnessed up until then: hundreds of staggered streaks of light, tearing through an ink-black sky. Part of me knew it was strict science. Another part of me was convinced it was magic. Who knew that a phenomenon that happens every day could resonate so profoundly?
Every day, on average, more than 40 tons of meteoroids strike our planet. Most are tiny specks of dust that disintegrate harmlessly high up in Earth’s atmosphere, producing a slow drizzle of “shooting stars” in the night sky. Meteors (what they’re called before they enter our atmosphere) are made of cosmic material–silicate rock, iron, and metals–left over from the early formation of our solar system.
Where do the Perseids come from?
As the Earth rotates around the sun this weekend, it will pass through the debris field of the comet Swift-Tuttle, a dirty snowball of remnants that never became planets nor stars. The comet takes about 133.2 years to orbit the sun. As it moves, a tail of gas, ice and dust is left behind it.
Each year, from mid-July to early August, the cosmic debris in this comet’s tail culminate in an evening spectacular called the Perseids.
When and How to View
This year, the meteor shower peaks late Sunday (8/11) into early Monday (8/12) just before dawn.
Find a dark field away from any light pollution. Look for the constellation Perseus, where the Perseids derive their name. It should be observable in the northeastern sky. During a Perseid meteor shower, you can expect to observe up to 100 meteoroids in an hour.
What to Bring
What’s nice about the Perseids is you don’t need any special viewing equipment. The naked eye is adequate. Grab a blanket and/or lawn chair, a cup of warm liquid, some snacks, and sit back to wait for the forthcoming light show.
NASA has a Meteor Counter app that iPhone users can download. Viewers of the Perseids can help report how many they see within a particular time frame. The app’s “piano key” interface allows you to tap keys as you view meteoroids. It records critical data for each meteor: time, magnitude, latitude, and longitude, along with optional verbal annotations. Afterward, these data are automatically uploaded to NASA researchers for analysis.
While you’re out there, you might as well turn an otherwise passive (albeit amazing) viewing experience into a participatory one in the name of citizen science.
SciStarter wishes you a happy viewing for this year’s Perseids. If it doesn’t make you feel too cheesy, make a wish when you see your first meteoroid. I know the fifteen year old in me won’t forget to.
If you live in Alabama, you can participate in the Alabama Meteor Tracking Project.
