(Woman) Today I want to talk about the Earth's last major climatic shift, at the end of the last ice age. But first, let's back up a moment and review what we know about climatic change in general. First, we defined climate as consistent patterns of
(man) I know you're anxious to get your permits and get started. But there're just a few things I'd like to mention that might help you avoid trouble during your stay. First of all, make sure you carry adequate water. You'll need it if you're hiking
(woman) Last week we talked about Anne Bradstreet and the role of women in the Puritan colonies. Today I want to talk about some other women who've contributed to American history --- some famous and some not-so-famous. The first woman I'd like to t
(man) Today we're going to talk about shyness and discuss recent research on ways to help children learn to interact socially. Many people consider themselves shy. In fact, forty percent of people who took part in our survey said they were shy --- t
(woman) We've just seen two contemporary large birds that cannot fly: the emu and the ostrich. Over here is an interesting specimen from the past. This stuffed animal is not the giant penguin it appears to be, but an auk. This particular kind of auk
(woman) I'd like to begin by thanking Dr. Kane for inviting me to be here today. Although I'm not a geologist, I have been collecting minerals for years. My collection is rally diverse because I've traveled all over the world to find them. Today I'v
(man) Welcome to Yellowstone National Park. Before we begin our nature walk today, I'd like to give you a short history of our National Park Service. The National Park Service began in the late 1800's. A small group of explorers had just completed a
(woman) Before I tell you about the interesting discovery related to Tyrannosaurus rex, I need to review something we studied last semester --- the difference between what are commonly called cold-blooded and warm-blooded animals. In warm-blooded an
(Man) Thank you all for coming out this evening to meet sociologist Ellen Lambert. Ms. Lambert specializes in research on the workplace and recently has been writing about the future of work. This topic should be of special interest, since I know ma
(man) I'm sure almost every one of you looked at your watch or at a clock before you came to class today. Watches and clocks seem as much a part of our life as breathing or eating. And yet, did you know that watches and clocks were scarce in the Uni
(woman) This room is devoted to electric fish. The eel in the tank behind me can produce a strong jolt of electricity to stun its prey, but most of the fish in here produce only weak electrical impulses that are useful for navigating, locating food,
(Woman) So, why did what is now called modern dance begin in the United States? To begin to answer this question, I'll need to backtrack a little bit and talk about classical ballet. By the late 1800's, ballet had lost a lot of its popularity. Most
(man) I need to make sure you understand how to get housing for next year. When you entered as first-year students this year, the school assigned you to a dorm and a roommate, but next year as returning students you'll choose both your roommate and
(MA) Now let's focus on comics in the 1950's. Early in the decade sales were down, so publishers started looking for some new angle to get their readers interested again. They found what they were looking for with horror comics --- stories about gho
(WA) OK. In the last class we talked about the classification of trees, and we ended up with a basic description of angiosperms. You remember that those are plants with true flowers and seeds that develop inside fruits. The common broadleaf trees we
(WA) The Old Canada Road is a long-lost trail between the Canadian province of Quebec and Maine, in the northeast corner of the United States. Yes, it really was lost, and finding it again was a complex process that involved state-of-the-art technol
(MA) As you probably know, log structures are gaining in popularity. They are no longer just the simple country homes that we think of as the traditional log cabin. Some upscale homes now incorporate natural round logs in ceiling beams and walls. Pe
(man) Today I want to discuss fossil fuels such as coat, oil, and natural gas. The term fossil fuel refers to the trapped remains of plants and animals in sedimentary rock. You see, living plants trap energy from the sun by the process of photosynth
(woman) We've been together now in this pottery class for several weeks, and I feel you are all doing very well. I thought you might be interested in hearing about a ceramics workshop that will be held here at the college next month. Kate Ferguson,
(WA-MM) Not long ago, some of you may have read about a team of mountain-climbing scientists who helped to recalculate the elevation of the highest mountain in the world: Mt. Everest. Of course, the elevation of Mt. Everest was determined many years
