Weather and Climate (Earth and Space Systems)-- Lesson Plans and Information

What does the weather do to the ocean currents?

Ocean water and currents affect the climate. It takes a greater amount of energy to change the temperature of water than land or air; water warms up and cools off much slower than land or air does. As a result, inland climates are subject to more extreme temperature ranges than coastal climates, which are insulated by nearby water. Over half the heat that reaches the earth from the sun is absorbed by the ocean's surface layer, so surface currents move a lot of heat. Currents that originate near the equator are warm; currents that flow from the poles are cold.

The Great Ocean Conveyor Belt

The great ocean conveyor belt is an example of a density-driven current. These are also called thermohaline currents, because they are forced by differences in temperature or salinity, which affect the density of the water.

The great ocean conveyor belt begins as the coolest of all currents - literally. At the beginning of the conveyor belt:

The Gulf Stream delivers warm, and relatively salty, surface waters north to the Norwegian Sea. There the water gives up its heat to the atmosphere, especially during the frigidly cold winters. The surface waters cool to near freezing temperatures, at which time they become denser than the waters below them and sink. This process continues making cold water so dense that it sinks all the way to the bottom of the ocean.

During this time, the Gulf Stream continues to deliver warm water to the Norwegian Sea on the surface. The water can't very well pile up in the Norwegian Sea, so the deep cold water flows southward. It continues to flow southward, passing the Equator, until it enters the bottom of the Antarctic Circumpolar current. It then drifts around Africa and Australia, until it seeps northward into the bottom of the Pacific.

Watersheds, Water Clarity & Human Impact on Lake Tahoe

Lake Tahoe has become a symbol of the controversial balance between preserving and expanding into natural systems. Tahoe’s clarity has also been decreasing since at least 1968; down from 100 feet of visibility to about 70 feet nowadays. Fine particles from urban expansion is one of the main causes, as well as the introduction of invasive species. These photos and questions will help students to understand some of the reasons why Tahoe is becoming murkier. They can provoke relevant ideas about how to slow that loss of clarity down or even reverse it, so that future generations of people and native species can enjoy and rely on this magnificent lake, just as we have done in the past. Simply click the paperclip in each image to see the prompts pertaining to each photo. This collection is ideal for a discussion-based lesson.

Voyage of Discovery: Lewis & Clark explore Louisiana.

Images related to the Corps of Discovery. Most people think of the Lewis and Clark Expedition as one of geographic exploration. However, President Jefferson charged them to study ethnography, biology, zoology, meteorology, botany and geology. They were required to make detailed maps of their travels and keep a journal about their experiences. Sculptures, paintings and other forms of artwork have been included to illustrate the many interpretations of Lewis and Clark.

Upward Bound Tech & Tour - Intro to the Smithsonian Center for Learning and Digital Access' Learning Lab

Taking a great portrait is more than just taking a quick snap of a face. It requires thoughtful contemplation and a variety of choices by the photographer. We'll examine a collection of photographs that illustrate various principles of portrait photography and that will help students to understand the parts of a digital artifact. 

LENS 1 | One lens to consider when looking at an artifact is its context and the impression it gives you. Using "see, think, wonder" strategies, we consider:

  • What do you see?
  • What do you think about it?
  • What makes you say that -- what evidence is there for that - on what are you basing your opinion?
  • What does it make you wonder?
  • Why does something look the way it does or the way it is?


LENS 2 | Analyzing great photographs to provide inspiration for your own photography pursuits 

What makes a strong image?

  • angles (eye-level, high angle, low angle, and bird's eye);
  • light and shadow;
  • framing;
  • shot length (long-shot, medium-shot, close-up, & extreme close-up);
  • mood--capturing a feeling or emotion in a photograph; 
  • scale--how big or small subjects look; and
  • sense of place--capturing the feeling of a place. 

Click into each photo and on the "paper clip" annotation icon to read more information (metadata!)

We will then discuss publishing guidelines and other policies that will help students make their best collections.

Triumph and Tragedy: Pittsburgh's History of Innovation in Science

This collection connects the 2019 National History Day theme of "Triumph and Tragedy in History" to a selection of topics related to Western Pennsylvania, science, and innovation. This region’s history features many stories of triumph over tragedy, including two key events: the creation of the polio vaccine at the University of Pittsburgh, and Rachel Carson’s fight against the detrimental effects of pesticides on the environment.

The first half of the collection focuses on the story of the polio vaccine, including context on the polio virus, movements to raise money for a cure, and Salk's work in Pittsburgh. It also mentions Henrietta Lacks, whose cells were used without permission for a range of medical advancements, including the polio vaccine.

The second half of the collection highlights Rachel Carson, her talent for writing and interest in animals as a child, how she came to be interested in the effects of DDT, and her legacy as an environmentalist. 

These objects, images, and sources can be used to help form an idea for a project, provide a new angle on an existing project idea, or lead to new ways of including primary sources into NHD projects. They are drawn from a range of primary source repositories, which can be helpful sources of information for students working on these topics.

Time and Navigation

If you want to know where you are, you need a good clock. For centuries sailors have used clocks to locate where they are out at sea. Today we use synchronized clocks and orbiting satellites for location. In this episode of STEM in 30, we'll take a look at the challenges of navigating at sea, in the sky, and even in space.
