Introduction to the science concept of claims, support and reasoning.
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.

This collection explores Alexandre Hogue's 1933 painting Dust Bowl through a global thinking routine called "Beauty and Truth." Supporting materials help build historical and scientific context.
“Some may feel that in these paintings . . . I may have chosen an unpleasant subject, but after all the [drought] is most unpleasant. To record its beautiful moments without its tragedy would be false indeed. At one and the same time the [drought] is beautiful in its effects and terrifying in its results. The former shows peace on the surface but the latter reveals tragedy underneath. Tragedy as I have used it is simply visual psychology, which is beautiful in a terrifying way.” -Alexandre Hogue
With the collapse of the Roman Empire, Europe fell into the Middle Ages. During this period, strict dogmas restricted medieval literature, art, science, and technology. In the late Middle Ages, the germination of capitalism emerged first in Italy in Europe under various conditions. The commodity economy operates through the market. The choice of purchase, bargaining, and contract-making in the market are all voluntary actions after consideration. This is the embodiment of freedom. Of course, if we want to have these freedoms, we must have the freedom of ownership of means of production, and the common premise of all these freedoms is human beings. Freedom. At this time, Italy calls for human freedom, and stale Europe needs a new ideological movement to promote human freedom. The emergence of the bud of capitalism has also provided the possibility for the rise of this ideological movement. The prosperity of the urban economy makes the wealthy businessmen, workshop owners and bankers who have great success and wealth believe more in their personal values and strength, and are more full of the spirit of innovation, enterprising, risk-taking and winning.

This collection supports the free Smithsonian Science How webcast, Exploring the Amazing World of Lichens featuring Dr. Manuela Dal Forno, scheduled for March 28, 2019. Manu is a scientist at the Smithsonian who studies lichens, a lichenologist. She collects lichens from all over the world, depositing them into the U.S. National Herbarium, which is located at the Smithsonian’s National Museum of Natural History. Manu identifies the lichens she collects with observations of how the lichen looks, their DNA data and where they were found.
Lichens are a symbiotic relationship between algae and fungus. They have been on earth for millions of years, living on rocks, trees, and soil in all different habitats on all seven continents. Even though lichens are all around us, scientists are still learning about what they are, where they live, and how many different species of lichens there are.
Fungus is any group of spore-producing organisms feeding on organic matter, and include molds, yeast, mushrooms, and toadstools. Algae is a simple, non-flowering plant. Algae contain chlorophyll and produce sugar through photosynthesis, like other plants, but do not have true stems, roots, leaves, or vascular tissue like most other plants. Lichenization is a fungal lifestyle, and therefore the name of lichen is the name of the fungus component.
When you look at a lichen, what you’re looking at is the “house” that the fungus and algae grow together. Scientists call this house a “thallus.” When algae and fungus come together to form this house, we see a lichen. This partnership is called a symbiotic relationship, because it helps both the fungus and algae survive. Research has shown that lichens are not a natural biological group, meaning they do not all come from a single common ancestor, in other words, lichens have many origins. Currently there are almost 20,000 species of lichenized fungi known.
In this symbiotic relationship, the fungus and algae benefit from being associated with each other. The fungus provides the house, its shelter (the thallus). This shelter helps the algae survive in habitats where it would otherwise be exposed to the elements and possibly could not survive. The algae provide food for the fungus, in the form of sugar. The sugar is a byproduct of photosynthesis that occurs within the algae.
Lichens are very important for the environment. They are an important food source for many animals, provide nest materials for birds, and provide habitat and material for biomimicry for insects and other organisms.
Lichens are also important for humans by providing natural dyes, perfumes, litmus paper, and even food. Humans even use lichens as bio-indicators, organisms that help humans monitor the health of the environment. Some species of lichens are sensitive to environmental pollution, so their presence or absence can help us understand more about the health of the environment, like air quality.
Lichens produce over one thousand different chemical compounds, most of them unique to lichens. These compounds include acids and pigments. Some chemicals may even fluoresce under UV light, making them important components for lichen identification.
Lichens have DNA, which is used to identify lichen and compare relationships amongst and within species. DNA analysis has been an important tool for lichenologists in identifying and understanding the biodiversity of lichens.

This collection can be used as a pre- and post-resource to support the free Smithsonian Science How webcast, Exploring Fossil Ammonoids with Paleobiologist Lucy Chang. During the 30-minute program, your students will have an opportunity to interact with the scientist through live Q&A and polls.
This collection contains objects from the Smithsonian’s National Museum of Natural History. Many of the specimens in this collection are fossil ammonoids, but other mollusks are included for comparison. Also included in the collection is a companion worksheet for students (with teacher key) to express their newly gained knowledge about ammonoids.
Ammonoids are an extinct group of marine mollusks that belong to the subclass Ammnoidea and the class Cephalopoda. A popular and well-known subgroup of ammonoids are ammonites. The closest living relatives of ammonoids are also cephalopods like squids, octopods, and cuttlefish, while the modern nautilus is more distantly related.
Ammonoids had shells made of calcium carbonate just like today’s snails, clams, oysters, and other shelled mollusks. Ammonoid shells varied in shape and size. Some ammonoids had tightly coiled shells (planispiral), while others had uncoiled, irregularly shaped shells (heteromorphs). Regardless of shape or size, the shell provided the ammonoid with protection and possibly camouflage.
Ammonoid shells had interior walls (septa) that created chambers inside of the shell. These chambers were connected by a narrow tube structure called a siphuncle. The ammonoid could use the siphuncle to control the amount of gas and fluid in each chamber, giving it the ability to achieve neutral buoyancy and move about in the marine environment.
Although ammonoid shells are abundant in the fossil record, there is an extremely poor record of their soft parts being preserved or fossilized. Based off of their relationships to mollusks alive today, ammonoids likely had bodies that were soft. The animal would have lived exclusively in the last chamber of its shell with numerous arms extending in a ring around its mouth, eating plankton and detritus, dead or decaying matter. Scientists study the shapes and patterns of ammonoid shells and related species, fossil and modern, to learn about the extinct animal.
Ammonoids lived around the globe and were present on earth for a very long time, about 350 million years. The entire group went extinct at the end of the Cretaceous, about 66 million years ago, along with the dinosaurs.
The abundance of ammonoids in the fossil record and their long history on earth make them good fossils to study. Geologists use ammonoid fossils as guide or index fossils, helping to date the rock layers from which the fossils were found. Paleobiologists can use fossil ammonoids to learn about patterns of extinction and glean information about the group's evolutionary history.

The National Museum of African American History and Culture (NMAAHC) is the first museum on the National Mall to be recognized as a LEED Gold building due to its construction using renewable energy sources and locally-sourced building materials. LEED or Leadership in Energy and Environmental Design certifications are granted to buildings and other structures that meet global standards in areas such as water use, energy efficiency, and use of sustainable materials. To minimize energy use, the architects and engineers designed the building to allow lots of natural light inside of the museum. The Corona, the ornamental bronze-colored metal lattice that covers the museum like a crown covers a head, helps to keep the museum cool by allowing some sunlight inside, but by blocking the rest. As a result, the museum uses less electricity for lights and air conditioning.
But how does it work? Have your students complete the following experiment to find out!

This Learning Lab collection is designed to accompany the Pittsburgh CLO's teacher guide for Beyond the Moon. In this new Gallery of Heroes musical, fifteen-year-old Maya has big dreams of being the first person to set foot on Mars but believes she is simply too ordinary to become an astronaut. Her view of what is possible transforms when actual NASA astronauts past and present, including Neil Armstrong, Mae Jemison, and José Hernandez, take her on an amazing journey to discover that extraordinary feats are accomplished by regular people one step at a time.
The activity is based on "Touchdown," created by PBS Kids Design Squad. It was adapted by the Heinz History Center to include the story of the Alcoa aluminum innovation used for the legs of the Lunar Module.
