The evolution of ICT-based learning environments: which perspectives for the school of the future?
This paper briefly outlines the evolution of ICT-based learning environments discussing some of the main aspects that have characterised such evolution (eg, technological evolution, changed cognitive and pedagogical frameworks, changed role assigned to ICT-based systems in education). The objective is to point out how the implementation of innovative learning environments, based on advanced technology, is the result of the strict interrelation between educational and cognitive theories, technolo
Fighting Back! (Lesson)
This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut's immune system is suppressed during spaceflight due to stress and other environmental factors.
Out of Breath
This lesson goes over the parts of the human respiratory system and the gas exchange process that occurs in the lungs. It also covers changes in the respiratory system that occur during spaceflight, such as decreased lung capacity.
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.
In this activity, students are divided into a group of hormones and a group of receptors. The hormones have to find their matching receptors, and the pair, once matched, perform a given action. This activity helps students learn about the specificity of hormone-receptor interactions within the endocrine system.
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.
Windmill of Your Mind: Distributed Energy Goes to School
Students research the feasibility of installing a wind-turbine distributed energy (DE) system for their school. They write a proposal (actually, the executive summary of a proposal) to the school principal based on their findings and recommendations. While this activity is geared towards fifth-grade and older students, and Internet research capabilities are required, some portions of this activity may be appropriate for younger students.
Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ
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
Computer enhanced education in undergraduate dietetics programs
Since computer technology was reported as underutilized on a previoussurvey, the objective of this study was to strengthen the role of technology forundergraduate programs in food and nutrition. The purpose was to determinewhether attendance at a workshop on computer applications would increase thevariety and frequency of use of computer applications and educational materials inundergraduate nutrition programs and would stimulate the development of computerenhanced education materials.

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
NASA CONNECT The Venus Transit
In NASA CONNECT Venus Transit, students will learn about the importance of using scale models to represent the size and distance of objects in the solar system and beyond. They will be introduced to the astronomical unit (AU), the baseline distance from the Earth to the Sun, which astronomers use to determine the relative distances from the Earth to other planets, stars, asteroids, and objects in space. They will also discover fascinating facts about the Venus Transit, a celestial and historical
Musculoskeletal, Fall 2007
This sequence provides foundational basic science knowledge of the musculoskeletal system, integrated with clinical relevance.
Central and Eastern Europe: Peace Corps
provides lessons about stories, letters, and folk tales from experiences of Peace Corps volunteers in rural and urban areas of Central and Eastern Europe. Topics include folk tales, Macedonia, Romania, Bulgaria, fear of certain numbers, transition from a state-controlled system to a democracy, school in Ukraine, the importance of speaking another language, storks and cultural icons, and family traditions as macrocosms of larger cultures.
Pump It Up!
Students learn about their circulatory system by designing a pumping device that will effectively pump fluid through a given cardiovascular system.
Float a Boat
Design and build a vessel with its own propulsion system that will carry cargo across a wading pool. PDF document.
Environmental Landfill Management
Lesson objectives: Students will be able to identify what a pollutant is and its affects on the environment. The students will demonstrate knowledge of the vocabulary used in environmental management by the DOE and other federal agencies. The students will attain a basic understanding of waste problems within our environment and the fundamental concepts of the laws of nature, science, physics, and engineering. Students will construct and operate a small-scale leach-bed barrier system.

Essential Science for Teachers: Physical Science. Session 1. What Is Matter?: Properties and Classif
Matter is all around us,its what we and everything else are made of. Yet how do we define matter? What are the properties of matter that set it apart from something that is definitely not matter such as light? In this session, well build a working definition of matter, and distinguish between the different forms that it can take. Well also sort out the difference between essential and accidental properties of matter, and look at the role of classification in science,Students inv
