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
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.
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.
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
Absolute coverage measurements of ultrathin alkali-metal films on reconstructed silicon
Metal/semiconductor interfaces, particularly those involving Si, are of great technological and scientific interest. In atomically abrupt interfaces, many properties are determined by interatomic interactions over a few layers, i.e., over ~1 nanometer. The initial stages of growth of an atomic layer related to structural and electronic properties are thus important to thin film behavior. Surface science studies on metal-semiconductor systems often lead to contradictory conclusions regarding bond
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.
Community-Oriented Primary Care: A Path to Community Development
Although community devel- | H. Jack Geiger, MD, MSciHyg opment and social change are not explicit goals of community- oriented primary care (COPC), they are implicit in COPC’s emphasis on community organization and local participation with health professionals in the assessment of health problems. These goals are also implicit in the shared understanding of health problems’ social, physical, and economic causes and in the design of COPC interventions. In the mid-1960s, a community health cen
Fundamentals of Compressible Flow Mechanics
This book deals with an introduction to the flow of compressible substances (gases). The main difference between compressible flow and almost incompressible flow is not the fact that compressibility has to be considered. Rather, the difference is in two phenomena that do not exist in incompressible flow. The first phenomenon is the very sharp discontinuity (jump) in the flow in properties. The second phenomenon is the choking of the flow. Choking is when downstream variations don't effect the fl

Description not set
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.
Photoelectric Effect Virtual Lab
The Photoelectric Effect Virtual Lab was designed with the intent that students and teachers might explore one of the most important, non-classical, behaviors of light - the photoelectric effect. The ability of light, under the right conditions, to liberate electrons from the surface of metals, was one of the most profound mysteries of the late 19th and early 20th centuries. In this Virtual Lab, students will graphically explore the behavior of light with metals.
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.
Logiciels de construction de cartes de connaissances: Des outils pour apprendre
This article examines the possible uses of concept mapping software in a university or continuing education context. Concept mapping applications allow the student to graphically represent compiled information as a network of nodes and vectors. The article looks at several applications that may be used to make different kinds of maps, but mainly reviews teaching strategies that incorporate these tools as well as providing a number of planning pointers. It also summarizes the main advantages and
Improving Your Commute
Road traffic is a challenging societal problem, and with the increasing crowding of areas in and around cities, it is only becoming worse. With the proliferation of wireless connectivity, smartphones (think cheap embedded computers), it is now possible to continuously monitor urban areas using mobile sensors carried by people
Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a uniform
NASA KSNN What do animals need to live?
There are many different habitats on the Earth. These vary in the landforms, sources of water, and climate conditions. Plants and animals are specially adapted to live in their habitats. Animals suited to live in the desert (very dry, either hot or cold) would have a difficult time living in the tropical rain forest (warm and very wet). Grades K-2
