Arteries and veins of the zebra fish
Arteries and veins are blood vessels and are part of the circulatory system. Arteries take oxygenated blood away from the heart and veins bring blood back to the heart after it has circulated through the body. The circulatory system distributes oxygen to the body and also moves around nutrients.
Artemia inquiry lab
Artemia blood has blood cells that circulate in an open circulatory system.
A collection of fern plants in a California forest
Ferns are the most diverse group of seedless vascular plants. The leaves are compound and contain many little leaflets. The many leaflets contain spore spots. Ferns have a true root system, unlike the bryophytes.
This resource consists of a Java applet and expository text. The applet is a simulation of the voter experiment, an interacting partile system that consists of a rectangular array of sites. At each discrete time unit, a site is chosen at random, a neighboring site is chosen, and the color of the first site is changed to that of the neighbor. The applet illustrates clustering of the colors and convergence to consensus.

Case It! Case Study Learning via Simulations of Molecular Biology Techniques
Case It! is an NSF-sponsored project to promote collaborative case-based learning in biology education worldwide. This paper describes the latest version of the Case It! simulation software (DNA gel electrophoresis, Southern blotting, and PCR). Students use these open-ended molecular biology computer simulations to analyze case studies involving genetic diseases, then discuss results with their peers at other institutions via web-based "poster sessions." They also use Case It! software to gather
ESD.04J Frameworks and Models in Engineering Systems / Engineering System Design (MIT)
This class provides an introduction to quantitative models and qualitative frameworks for studying complex engineering systems. Also taught is the art of abstracting a complex system into a model for purposes of analysis and design while dealing with complexity, emergent behavior, stochasticity, non-linearities and the requirements of many stakeholders with divergent objectives. The successful completion of the class requires a semester-long class project that deals with critical contemporary is

The Ballad of Jessie Pearl
Book Trailer for "The Ballad of Jessie Pearl" by Shannon Hitchcock.
College of Southern Maryland Stem Director, Robert Farinelli, interviews Margy Stevens. Stevens is the assistant superintendent of Montgomery County Educational Service Center in Ohio. She is also the executive director of Ohio's first STEM (science, technology, engineering, and math) center, the Dayton Regional STEM Center (DRSC)—one of six in the country started by the National Governors' Association.
Fish are vertebrates, meaning they have a skeletal system to support their bodies. All fish live underwater. Fish have gills to help them breathe underwater and fins to help them swim. Most fish are cold-blooded, meaning their body temperature is regulated by the surrounding water temperature.
Tipping Points in the Earth System
Gradual Climate Change or "Tipping Points" in the system
1980 - 1988 Reagan boosts U.S. defense spending and proposes the Strategic Defense Initiative, an anti-missile system in space. New premier Gorbachev knows the Soviets can't match the U.S., and wants to liberalize and reconstruct the economy. After summits in Geneva, Reykjavik and Washington, the leaders agree to drastic arms cuts.
Quality in education has been regognized as an issue that should guide our efforts for improvement for many years. eLearning is the latest attempt to take advantage of developments in technology to improve learning. In this paper, we discuss the possibility of establishing a theory of elearning, the value of design patterns, and the possible scenarios of implementation by higher education institutions attempting to use new technologies in their courses of study. A survey concerning the elearning
Constantly providing feedback to on-line learning teams is a challenging yet one of the latest and most attractive issues to influence learning experience in a positive manner. The possibility to enhance learning groups participation by means of providing appropriate feedback is rapidly gaining popularity due to its great impact on group performance and outcomes. Indeed, by storing parameters of interaction such as participation behaviour and giving constant feedback of these parameters to the
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose
The purpose of the Space Launch Initiative (SLI) is "to identify feasible options for future NASA space transportation and enable a decision regarding whether the agency should proceed into full-scale development of a new reusable launch vehicle system." This news page has information on current developments, fact sheets, and vehicle concepts. Several technology summaries describe the various areas of research for the SLI. For example, using neural networks in the vehicle's control and navigatio
Two studies investigated the role and effectiveness of post-solution, reflective dialogues in physics tutorials. The first study investigated the instructional roles of post-solution discussions, their relationship to problem-solving discussions, and features that predict learning. Seven tutors individually guided 15 students as they worked on problems in the Andes physics tutoring system. Tutors adapted the post-solution discussions to students' ability levels and their performance on the curre
Pedagogical theory of today gives high priority to social components of learning. Within the field of computer supported learning there are many attempts to acknowledge this. One approach involves the addition of virtual characters to electronic learning environments. Such character enhanced systems are the focus of the present article. Firstly, a systematic overview is given of pedagogical benefits that have been proposed in the literature regarding character enhancement of electronic learning
