The boreal forest, which stretches across northern latitudes just south of the Arctic Circle, is a key region for studying climate change—and not just the impacts. Follow ecologists into Alaska's boreal forest to learn more in this new Science Bulletins video.
Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Each Bulletin is produced by AMNHs curatorial and scientific staff and a team of video producers, designers, writers, and educators using state-of-the-art technologies such as high-definition video, data visualization, and 3-D computer graphics to present the latest research.
The butterfly begins life as an egg, emerges as a caterpillar, and then undergoes a complete change in body form during development.
Go beyond the basics of field study—use math and science skills and dig in the dirt! Students learn how to count plants as part of a study of local biodiversity and calculating biodiversity indexes.
Major highways that connect Los Angeles and Las Vegas run through major habitats of bighorn sheep. These highways allow travel between Los Angeles and Las Vegas in just four hours, but what do they mean for the sheep?
Video, Educator Guide
Video profile of Dr. Clinton Epps, who studies bighorn sheep populations. Includes discussion questions about scientific practice and how scientists use DNA to study populations.
In winter, salt is regularly applied to melt ice on roads in the Northeast. But road salt runoff drains into streams and drinking water. Scientists have been testing freshwater in three regions of the Northeast for thirty years. The salt buildup has made some urban, suburban, and rural streams 25 percent as salty as seawater.
Did you know that when you look at a star, your eyes are capturing light that traveled all the way from the star to your eye? Learn more about how light carries information from distant objects.
You can't see the Sun's ultraviolet rays with your eyes—you just see their results on your freckled, tanned, or sunburned skin. Build a bracelet that immediately detects these invisible rays.
When does mixing every color under the rainbow create pure white rather than a murky brown or black? When light, not paint, is the medium—and you're subtracting, not adding, color.
White light is a mixture of all colors of visible light, but it doesn't always include every color of the rainbow. Build a spectroscope, and view the spectral fingerprints of different light sources.
