Strength of Materials
Students learn about the variety of materials used by engineers in the design and construction of modern bridges. They also find out about the material properties important to bridge construction and consider the advantages and disadvantages of steel and concrete as common bridge-building materials to handle compressive and tensile forces.

Animal Studies: Turtle
This turtle has a back full of green, mossy algae. When the turtle is stationary in the water, it can camouflage itself to look like a moss-covered rock.

The Lake Isle of Innisfree - Quiz
Students will be able to develop their personal response to Yeats' poem.
Slide Right on By Using an Inclined Plane
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
Sleeping Beauty Invades Rat's Genome
Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website (http://pga.mcw.edu) and the strains themselves accessible via a
Developmental Plasticity in Oak Leaves
This resource is a detailed manual of protocols and instructional information for carrying out an undergraduate laboratory exercise in plant biology and evolution, including student outlines, instructors notes, and suggested questions for laboratory reports.
Designing Bridges
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Students learn the steps that engineers use to design bridges: understanding the problem, determining the potential bridge loads, calculating the highest possible load, and calculating the amount of material needed to resist the loads.
Slinkies as Solenoids
In this activity, students use an old fashion children's toy, a metal slinky, to mimic and understand the magnetic field generated in an MRI machine. The metal slinky mimics the magnetic field of a solenoid, which forms the basis for the magnet of the MRI machine. Students run current through the slinky and use computer and calculator software to explore the magnetic field created by the slinky.
Tracking a Virus
Students simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups will already be tainted with the "virus" (sodium carbonate). After all the students have shared their liquids, the contents of the cups will be tested for the virus with phenolphthalein, a chemical that causes a striking color change in the presence of sodium carbonate. Students will then se
Surgical Device Engineering
This unit focuses on teaching students about the many aspects of biomedical engineering (BME). Students will see that it is a broad field that relies on concepts from each of the other disciplines of engineering. They will also begin to understand some of the special considerations which must be made when dealing with the human body. Activities and class discussions will encourage students to think as engineers to come up with their own solutions to some of the basic medical problems that have b

Inner and outer ear anatomy
Sounds are actually waves from vibrations. The outer ear catches these waves and funnels them down into the inner ear. The waves reach the eardrum and in turn make the eardrum vibrate. Three small bones receive these vibrations next, then a snail shell-shaped structure called the cochlea. The cochlea is filled with liquid, and this liquid stimulates hairs inside the inner ear. The hairs transmit the signal to the auditory nerve where the signal is taken to the brain and processed as sound.
Vanderbilt Mansion National Historic Site: Monument to the Gilded Age
describes this Hyde Park estate that includes a palatial Beaux-Arts mansion, stunning views of the Hudson River and Catskill Mountains, and over 600 acres of landscaped property. The mansion was built in 1895-8 by Frederick Vanderbilt, an heir of the fortune created by Cornelius Commodore Vanderbilt. Cornelius, at the age of 16, borrowed $100 from his parents, purchased a periauger (a flat-bottomed sailing barge), and began a ferry service now known as the Staten Island Ferry.
The Family Business: Ruth Asawa
Sculptor Ruth Asawa has been associated with some of the most notable figures in American 20th century art: Josef Albers, Buckminster Fuller, John Cage, Merce Cunningham, Robert Rauschenberg, and Jasper Johns. This Educator Guide is dedicated to highlighting arts education in the Bay Area and the model programs established by Asawa and her family.
Carnegie celebrates Wilf Paish
Carnegie celebrates Wilf Paish
A celebratory dinner to honour one of athletics' best known coaches has been held in Leeds.
The celebratory dinner commemorated the life and work of Wilf Paish who passed away at the start of last year. Yorkshire-based Paish was coach of javelin aces Tessa Sanderson and Mick Hill with more than 100 of the athletes who came under his guidance becoming Olympians.
Wilf trained to be a PE teacher at Carnegie College, now part of Leeds Metropolitan University before
Traditional Chinese Paper
This 1:48 video shows how one Chinese town still makes paper the traditional way. The students will learn how the bamboo is harvested, turned into pulp, and made into paper.
