Winter Field Lab: Snow Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. Students collect their own data from a snowpack, including measuring water equivalent, identifying types of snow metamorphism, finding evidence of precipitation patterns, and judging possible snowpack hazards. Back in the lab, students evaluate their data, draw conclusions, and make a report. This activity is designed for upper-level undergraduate and graduate-level geohydrology courses.
Were Dinosaurs Cold- or Warm-Blooded?: An Exercise in Scientific Inference
Both metabolic rates and brain masses are approximately 10 times as great in modern terrestrial warm-blooded animals (birds and mammals) as in cold-blooded terrestrial animals (reptiles) of the same body mass. This is one of several lines of evidence scientists have used to infer the mode of thermal regulation of dinosaurs and other extinct amniotes. In this exercise each student is assigned one of a number of dinosaurs. Students estimate brain mass from a drawing of a cranial endocast and body
Inca Investigation
This OLogy activity gives kids a chance to test their investigation skills while learning about daily life for the Incas. Inca Investigation begins with an introduction to archaeologist Craig Morris and the ancient Inca city that his team excavated in the Andes mountains. Then kids are given detailed directions for how to play Inca Investigation, which includes tips to help them better examine evidence. At any time, they can get help, learn how to read a plan, or browse a book about Inca history
What's the Big Idea? Archeology
This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about archeology Piecing Together the Puzzle of History looks at how archaeologists use clues to assemble a picture of the past. Clues to the Past explains that, like all scientists, archaeologists begin with a question they want to explore. Fieldwork Is Where They Dig In explores the challenges of finding a site to excavate. Evidence of an Era has an overview of th
Buying the War
Four years ago on May 1, President Bush landed on the aircraft carrier USS lincoln and delivered a speech in front of a giant "Mission Accomplished" banner. Despite profound questions and the increasing violence in Baghdad, many in the press confirmed the White House's claim that the war was won. How did they get it so wrong? How did the evidence disputing the existence of weapons of mass destruction and the link between Saddam Hussein and 9/11 continue to go largely unreported?Author(s):
Capitalism in crisis.
Is there a crisis in American capitalism? Investment industry giant John Bogle says that as more and more money managers take control over corporations on Wall Street, Main Street is paying the price. Named by Fortune magazine as one of the four "Giants of the 20th Century," Bogle tells Moyers: "The evidence is quite compelling that today corporations are run in a very important way to maximize the returns of its managers at the expense of its stockholders." Also on the program, NPR's Deborah
Empirical Research Methods in Software Engineering
This course will explore the role of empiricism in software engineering research, and will prepare students for advanced research in SE by examining how to plan, conduct and report on empirical investigations. The course will cover all of the principal methods applicable to SE: controlled experiment, case studies, surveys, archival analysis, action research and ethnographies, and will relate these methods to relevant metatheories in the philosophy and sociology of science. The course will critic
Jerome Groopman on the Changing Medical Profession Jerome Groopman speaks with Andrew Martin about how regulation of shift length, the struggle to control costs, and the rise of “evidence-based” medicine have changed how doctors learn and practice.
Global Temperatures Chanting and enchanting animals - Chap. 6/6 This video shows how frogs are becoming extinct. Researches travel to a stream to try and find a female toad that is disappearing. They look under rocks, in water, and under leaves. They have searched this area six times and have not found any female, they would like to find one so they can use it for reproduction and save it from extinction. They explain why there is such an amphibian extinction currently going on, the eviden Gravity and Branes The American Revolution History: DaVinci's Outline In The Last Supper?

In this activity, students analyze the global temperature record from 1867 to the present. Long-term trends and shorter-term fluctuations are both evaluated. The data is examined for evidence of the impact of natural and anthropogenic climate forcing mechanisms on the global surface temperature variability. ...
Ideas that may explain why the force of gravity is so weak are presented in this video. Does the weak force of gravity offer evidence of a ten-dimensional world? Find out more now in this interesting video! Run time 05:26.
This is an 11-minute video that explains both the geographical and political causes of the Revolution. This would be a good video to start a study of the war and includes primary document quotes. Best used with a map of the colonies so students could follow the evidence better.
Did Leonardo DaVinci use his own shadow to create the outline of Jesus in The Last Supper? James Williams speaks with a researcher who has found evidence in Leonardo's manuscripts suggesting that's the case.
This video explains how a hurricane is born. Scientists are given a challenge to find evidence from ancient hurricanes that may resemble current threats. This video is from the Naked Science series. This is Episode 10 from Season 1 and it is suitable for older elementary, middle-school, and high school students.
From Dragonfly Tv. Deborah and Brittani live in Juneau, Alaska, which is home to 38 glaciers flowing from the gigantic Juneau Ice Field. The girls love being outside, especially in the short Alaskan summers, so they decided to check out a glacier up close at the Mendenhall Glacier Visitor Center. The center has cool exhibits that explain the science behind glaciers-like the fact that a glacier is a river of ice that moves because of its own weight and that the Mendenhall Glacier receives abo
A teacher models how to draw inferences from evidence in a CSI text. This is a very good example for learning to make logical inferences from text.

"The search for Earth-like planets is reaching a fever-pitch. Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration? If things dont work out on this planet or if our itch to explore becomes unbearable at some point in the future, astronomers have recently found out what kind of galactic real estate might be available to us. We'll have to develop advanced transport to land there, 20 light years away. The q
Doctor explains what epilepsy is and basic historical evidence of the disease, tracing back the disease to Hippocrates in 400 B.C. and the Bible. Traces the path of the disease and modern treatments and how they work. Professional produced. Grades 5-12. 3:41 min.
This interactive activity adapted from NOVA provides students a way to gain a more accurate understanding of how science is done. Two videos, which feature the work of renowned scientists Percy Julian and Judah Folkman, demonstrate that while scientists may use an orderly approach to learn new information and solve problems, they proceed along different paths in their quests. Instead of referring to a delineated set of steps, the term "scientific process" encompasses the true nature of scientifi
