Conservation organizations teamed up to document the climate vulnerability of mountain springs that support unique ecosystems. Now, the Alliance they formed facilitates restoration work to enhance habitats and improve resiliency.

This art history video discussion examines Hieronymus Bosch's "Last Judgment Triptych", 1504-08, Akademie fur bildenden Kunste, Vienna, overall dimensions.

This lesson provides teachers with support for using text-dependent questions to help students derive big ideas and key understandings while developing vocabulary from the biographical text, Boss of the Plains. This biography relates the life of John Batterson Stetson as a hatting apprentice until he was diagnosed with tuberculosis and decided to explore the American West. During his time with the people of the West, he invents a better hat, nicknamed "Boss of the Plains," - the first real cowboy hat.

This excerpt from WGBH's Evening Compass news program summarizes events of the first year of the 1974 Boston school desegregation plan.

The lessons in this issue of Smithsonian in Your Classroom introduce the work of botanists and botanical illustrators, specifically their race to make records of endangered plant species around the world. “Very little of the world’s flora has been fully studied,” says one Smithsonian botanist, “and time is running out.” In the first lesson, students gets to know six endangered plants. They examine illustrations, photographs, and dried specimens of the plants as they consider this question: If a scientist can take a picture of a plant, are there advantages in having an illustration? They go on to consider some of the big questions that botanists themselves must ask: Which of these species are most in need of conservation efforts? Are any of these plants more worth saving than others?In the second lesson, the students try their own hands at botanical illustration, following the methods of a Smithsonian staff illustrator. All that is required for the lesson are pencils, markers, tracing paper, and access to a photocopier.

Students are introduced to the work of botanists and botanical illustrators, and specifically to their race to make records of endangered plant species around the world. Students examine illustrations, photographs, and dried specimens of endangered plants and consider the conservation value of an illustration over a photographic image. In a second session, students try their own hands at botanical illustration and follow the methods of a Smithsonian staff illustrator. Pencils, markers, tracing paper, and access to a photocopier are required.

This lesson discusses the result of a charge being subject to both electric and magnetic fields at the same time. It covers the Hall effect, velocity selector, and the charge to mass ratio. Given several sample problems, students learn to calculate the Hall Voltage dependent upon the width of the plate, the drift velocity, and the strength of the magnetic field. Then students learn to calculate the velocity selector, represented by the ratio of the magnitude of the fields assuming the strength of each field is known. Finally, students proceed through a series of calculations to arrive at the charge to mass ratio. A homework set is included as an evaluation of student progress.

"La série Bouger, réfléchir, apprendre aide les enseignantes et enseignants et les responsables de l’activité physique œuvrant auprès des enfants et des jeunes de la maternelle à la 9e année à acquérir une littératie physique[1] - connaissances, confiance en soi compétences – en proposant des activités uniques, inclusives et amusantes.

Misant sur l’approche Apprendre et comprendre par le jeu (ACJ[2] ), les enfants tentent de résoudre des problèmes tactiques par le jeu, réfléchissent aux options qui s’offrent et aux habiletés, et apprennent à appliquer ce savoir à divers contextes de jeu."

PHYSICAL SCIENCE
Have you ever heard of Gak? Take this hands-on activity to the next level and make your own bouncy balls so you can learn a little something about polymers.

ABOUT THE SCIENCE
In response to the July 22, 2016 Health Canada advisory, the bouncy ball experiment was recently updated.

Balls have been around for thousands of years and, believe it or not, the earliest balls were made of stone and wood! Not much bounce to those first ones!Bouncing balls were first made with natural rubber, but now, they can also be made of plastics and other polymers.
Polymers are molecules made up of repeating chemical units, and they can be either natural or synthetic. Natural polymers are wool, silk, and natural rubber, whereas synthetic polymers can be made of nylon, silicone, or synthetic rubber.
Bouncy balls (as a toy), were invented by a chemist who was experimenting with rubber. He found when he compressed rubber together under about 3500 pounds per square inch (psi) the result was a really durable sphere capable of extremely high bounce. Other factors that affect a ball’s ability to bounce are: temperature, outside coverings, different surfaces for bouncing and whether or not the ball is solid or inflated with air

Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.

In this activity, students examine how different balls react when colliding with different surfaces. Also, they will have plenty of opportunity to learn how to calculate momentum and understand the principle of conservation of momentum.

The Bowline (ABOK # 1010, p 186) makes a reasonably secure loop in the end of a piece of rope. It has many uses, e.g., to fasten a mooring line to a ring or a post. Under load, it does not slip or bind. With no load it can be untied easily. Two bowlines can be linked together to join two ropes. Its principal shortcoming is that it cannot be tied, or untied, when there is a load on the standing end. It should therefore be avoided when, for example, a mooring line may have to be released under load.

The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation.
