Just Passing Through (Lesson)
This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.
This lesson describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.
A Robot in Kindergarten
These thought are the result of work in progress, started in 1999, within the scope of the Trás-os-Montes Digital/SCETAD, project (sub-project: ICEI – Computers in Early Childhood Education Contexts). The work took place in Portuguese kindergarten rooms, with children aged 3, 4, 5 and 6. The ICEI sub-project aims to promote the use of ICT in a playful but pedagogical way, be it free or directed. This use is intended to occur within the scope of activities developed for the micro-spaces of the
In this activity, students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines.
A Closer Look at Oil and Energy Consumption
Students analyze international oil consumption and production data. They make several graphs to organize the data and draw conclusions about the overall use of oil in the world.
Alles Introductory Biology - Illustrated Lecture Presentations
These PDF files are Illustrated Lectures from his Earth history class (entitled introductory biology). The PDF files contain a lot of projection-ready graphics that may be useful in introductory Earth Science lectures. Lecture topics include the nature of science, cosmological evolution, biological evolution, life as a chemical function, The Hadean, Archean, Proterozoic, Paleozoic, Mesozoic and Cenozoic Eons, life and energy and biology and society.
Alternative Strategies to the Use of Vertebrates in Undergraduate Physiology Labs
There are many reasons to seek alternatives to the use of vertebrates, including cost and concerns with use of vertebrates in undergraduate laboratories. This major workshop explores examples of alternatives, including: a) an exploration of thermoregulation without using animals at all, b) an investigation of actomyosin function and membrane excitation using giant alga, and c) using insects to investigate taste receptors and digestion. This workshop explores the importance of providing good back
TALAT Lecture 4101: Definition and Classification of Mechanical Fastening Methods
This lecture introduces the principal types of mechanical fastening methods, i.e. screw joints, folding, riveting and clinching by definitions and classification; it illustrates the great variety of types of mechanical fastening methods and systems available for joining aluminium parts. General mechanical engineering background is assumed.
Math Literature Connections: Patterns and Algebra
Ideas and activities that use Two of Everything, One Grain of Rice and the King's Chessboard to introduce students to function machines and input/output tables. Links to appropriate templates are also provided.

Towards a targeted surfactant stabilized ultrasound contrast agent
Gas-filled microbubbles are highly effective when used as ultrasound contrast agents due to the large difference in acoustic impedance between the gas in the bubble and the surrounding blood. The surfactant-based contrast agent ST68 (Span 60, Tween 80) developed in our laboratory (US Patent # 5, 352, 436) and filled with sulfur hexafluoride (SF6), was modified in an attempt to make the agent target specific. Modifications to the agent were done by incorporation an anchor molecule, phosphatidylet
Novel associated PVA/PVP hydrogels for nucleus pulposus replacement
Degenerative disc disease in the lumbar spine is marked by a dehydration of theintervertebral disc and loss of biomechanical function of the spinal unit. Since thecurrent surgical procedures are ineffective in restoring natural biomechanical functionback to the diseased disc, researchers have looked to replace the intervertebral disc.These designs are flawed in that they either donâ t restore natural movement back to thespinal unit, require surgeries that are highly invasive, or they further p
In this Design Challenge activity students will explore how structure relates to function as they design devices to save Fido.
In this activity, students can select values for quadratic function coefficients, plot and explore multiple functions.
Oil and Sugar: Contemporary Art and Islamic Culture
The Institute for Contemporary Culture presented the third annual Eva Holtby Lecture on Contemporary Culture on November 20, 2008. Glenn Lowry introduces his lecture, Oil and Sugar: Contemporary Art and Islamic Culture, examining relevant and topical cultural issues of international scope.
Natural Inquirer Journals: Tropical
In the Tropical edition of the Natural Inquirer you will learn about different types of plants and animals. The tropics are the home of a variety of biomes, or regions with different kinds of vegetation and other life. Tropical biomes are largely defined by the amount of rainfall they get. In the tropics, you might find rain forests, dry forests, shrub lands, tropical plains called savannahs, and deserts. Scientists working in the International Institute of Tropical Forestry, or IITF, conducted
AlgTop13: More applications of winding numbers
We define the degree of a function from the circle to the circle, and use that to show that there is no retraction from the disk to the circle, the Brouwer fixed point theorem, and a Lemma of Borsuk. This is the 13th lecture of this beginner's course in Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW.
Creating criminals: prisons and security in an insecure world, Baroness Vivien Stern
Baroness Vivien Stern, Senior Research Fellow, International Centre for Prison Studies, King's College London, is one of the world's leading scholars and campaigners working on prison reform.
The Law of the Internet
The Internet is at once a constructive and disruptive technology. As more and more of our lives move online, we are faced with opportunities to do new and amazing things. Concurrently, we encounter problems that no one anticipated as we collectively built the internet as we know it today. This seminar will consider some of the most intriguing of the issues to which the advent of the internet has given and continues to give rise. It will focus on a cluster of topics about which any computer user
