Methods and Alogrithms for System Design
System design is the central topic of this course. We move beyond the methods developed in circuit design and consider situations in which the functional behavior of a system is the first object under consideration.
System Identification and Parameter Estimation
This course is about non-parametric system identification based on estimators of spectral densities and its application to open-loop and closed-loop systems. Furthermore parameter estimation for linear and non-linear systems playes an important role.
The Immune System: Red Cell Agglutination in Non-Humans
This exercise presents the concepts of immunology from biochemical, evolutionary, and adaptive standpoints. While all organisms have developed some mechanism of defense against external agents, vertebrates have the most complex immune responses capable of exquisite specificity and long duration. This affords a distinct advantage to species with a relatively long life span and low fecundity. This exercise explores the relationship between immunologic stimulation of the host with foreign antigens
Strengthening Biology Teaching by Working with the Local School System
This object was developed to strengthen the level of collaboration between educators at all levels. It should be used to develop workshops, curricula, and projects with the intent of increasing the amount of communication between educators at different levels, and to promote a better exchange of information ...
Microprocessor Based Digital System: From Bits to Systems
This course is oriented to gain skills that enable to design a microcontroller based digital system, from its initial design to putting it to work. The course also aims to give an overview of the impact of these systems in our society, and their influence in our actual lifestyle, shaping our lives.
Order Out of Chaos: Our Solar System
Why do all the planets orbit the Sun in the same direction and why are the planets closest to the Sun so different from the gas giants farther out? In this session, participants gain a better understanding of the nature of the solar system by examining its formation.
Unlocking the Endocrine System
Students learn how the endocrine system works and compare it to the mail delivery system. Students discuss the importance of communication in human body systems and relate that to engineering and astronauts.
A Cow’s Digestive System
Learn how a cow eats and digests food in this video segment from Nature.
A Personal Account of Efforts to End School Segregation in a Southern School System
The Brown Decision, whose 50th Anniversary was observed in 2004, was a landmark case that ended the doctrine of separate but equal. During the observation of the anniversary, many pundits reflected on the political, social, and historical significance of Brown. This article takes a different approach in reflecting on the importance of Brown. A historical context is provided that reveals the conditions that existed in the south prior to and after the Brown Decision. The author tells the poignant
3.2 - Clock System on the ez430
Describes how the clock system works on the ez430.
The Language of Mathematics (23): Cartesian Coordinate System
This video starts in an unlikely place, the instructor's car, where he begins his discussion of the Cartesian Coordinate System.
Bartering--A System of Exchange
By participating in a game called "Barter Bag" students will be introduced to the concept of trade. This introduces students to the concept of bartering.
A Walk Through the Solar System
A practice in scientific notation, measurement, and scale distances, this lesson plan integrates mathematics into the science curriculum.
African Americans and the United States judicial system
Harvard law professor Alan Dershowitz comments on the inability for Black Americans to receive fair treatment in the United States judicial system.
Solar System Simulator
invites you to create a color image of your favorite planet or satellite from different vantage points in the universe. This is one of NASA's most popular sites and receives 36,000 requests per day.
Investigating the Climate System: Weather
This activity helps students learn how to find, interpret, and describe weather data. Students learn also about drought, flooding, wind and dust storms, hurricanes, and lightning, as well as the Tropical Rainfall Measuring Mission (TRMM) satellite -- the information it provides and why that information is important.
Investigating the Climate System: Precipitation
This is a 23-page educator's guide organized around three questions: How are rainfall rates measured? How is the intensity and distribution of rainfall determined? How can you study rain?
Investigating the Climate System: Energy
This site offers problem-based lessons that focus on questions: Does ground surface influence temperature? How important is water evaporation to the cooling of a surface? If my town grows, will it affect the area's temperature? Why are summer temperatures in the desert southwest so much higher than at the same latitude in the southeast?
Investigating the Climate System: Clouds
This activity casts students as interns in a state climatology office. Their assignment: to investigate how clouds form, how they're classified, and their role in heating and cooling the earth. This 30-page guide also helps students understand why clouds (and the study of them) are important.
Inside the Human Body: The Respiratory System
This Web site from the Canadian Lung Association contains an excellent collection of learning resources about the respiratory system for grades 1-12. Content varies according to grade range; for instance, the section for grades 1-3 covers basics of lungs and their function with an illustrated story, coloring book, interactive games, and downloadable worksheets. Older students focus in on smoking, air pollution, and other issues in addition to covering respiratory system biology. As with the sect
