This unit looks at the human being in the context of an individual life cycle, examining some of the processes that contribute to the formation of a new person. After a brief discussion of historical ideas about human conception, and about contraception to the present day, we look at the cells involved in the conception and development of a new individual. Gamete production (that is, production of mature cells able to unite with another in sexual reproduction) in both men and women is introduced

Food Fight: A Teach-in On the 2007 Farm Bill
Michael Pollan moderates a panel discussion of the 2007 farm bill, now being debated, with guests Dan Imhoff, the author of Food Fight: A Citizen's Guide to the Farm Bill; George Naylor, Iowa corn farmer and president of the National Family Farms Coalition; Ann Cooper, Director of Nutrition Services for the Berkeley school system, and other leaders in the effort to reform federal agricultural policies. Every five years or so, the President signs an obscure piece of legislation that determines w
Dynamic manipulation schemes of geometrical constructions: Instrumental genesis as an abstraction pr
Dynamic manipulation of geometrical constructions enabled by a specially designed computational tool, called variation tool, is studied during the implementation of proportional geometric tasks in the classroom. The analysis combined the use of two theoretical frameworks: instrumental genesis and situated abstraction. The Dynamic Manipulation Schemes (DMS) developed by 13-year-old students based on the use of the variation tool are reported in the paper. It is indicated that situated abstraction
The OTTER Sami tent OER
This is a reproduction of the Second Life Sami tent and is for free distribution within Second Life as a repurposable OER. It is available in two clearly identified forms: 1. As a single SL artefact, where all discrete items have been linked together to make a whole. 2. As a number of discrete SL artefacts. In addition, this OER includes two SL training guides: one for students and one for tutors. Users are encouraged to first read the 'Handout for the Sami tent OER' .

Effects of drugs on pulsation rate of blackworms (Lumbriculus variegatus)
In this investigative lab, students observe blackworm pulsation rate in normal conditions and observe how pulsation rate is affected by drugs. This lab stresses the circulatory system, but can also be used for homeostasis, behavior, toxicology, and nervous system labs. Part I guides the student through blackworm handling procedures and initial observations of the blackworm's behavior and circulatory system. Part II is a student-led investigation in which the students design and run their own exp
Changing the Education Culture through Technology
Technology has a potentially rich, but largely unrealised, role in teaching and learning. This role is defined variously by what the teacher has available, has had time to learn, or can find an appropriate use for, and by what students have access to, are familiar with, and are willing to use. In all of these ways, technology usually plays an adjunct role to others, more traditional modalities for teaching and learning, including lecture, laboratory, library, textbook, tutorial, and practicum.
Lecture 16 - 11/18/2010
Design Generation of the Central Asian Caravanserai
Challenges for the study of Islamic architecture include its abundance and diversity in expression and its classification based on distinct functional or stylistic types. We address these issues by presenting shape grammars as a methodology for the analysis and design generation of Islamic architecture, with a specific example in the form of a parametric shape grammar for central Asian caravanserais. The grammar is developed by identifying distinct design types. Shape rules are created based on
Reasons for a Drug-Free ADHD Treatment
Reasons for a Drug-Free ADHD Treatment. Part of the series: Drug-Free ADHD Treatment Options. There are many reasons why people choose a drug-free treatment for ADHD. Learn about the benefits of natural treatments in this video clip from a medical professional. (1:57)
Introducing QCDA (Qualifications and Curriculum Development Agency)
The QCDA aims to be at the heart of England’s education system, building on the work of their predecessor, the QCA. Their job will be to develop the curriculum, improve and deliver assessments, and review and reform qualifications. The short video explains more about their work.
Biochemical Analysis of Vertebrate Skeletal Systems
This exercise was developed to look at the structure-function relationship in the skeletal system as it explores motion and force on evolution of the system.
Development of an Inexpensive Remote Operating Vehicle (ROV), Mountain Lake Virginia
This workshop details the physical description and use of a small ROV submarine, built in 2004 to explore and video bottom features at Mountain Lake, Giles County, Virginia. This project represents an ongoing co-operative effort between the Wilderness Conservancy at Mountain Lake, Roanoke College and Virginia Polytechnic Institute as academic partners. Mountain Lake is the only natural lake in the southern Appalachian Highlands. It is a low nutrient, high altitude, sub-alpine lake and associated
Webquest: The Split Brain
The brain is made up of two halves, the hemispheres. These hemispheres are united to one another through a system consisting of millions of nerve fibers. Therefore, each hemisphere is continually informed about what is happening in the other. What happens if the connection is broken?
6.2 Problems with Resemblance
Part 6.2. Explores Berkeley's and Locke's arguments concerning the resemblance of qualities and objects; that the perceived qualities of objects exist only in the mind or whether secondary qualities are intrinsically part of the object.
The Future of News
The diminishing pool of unbiased news networks should stick to what they do best.
PLoS ONE will be a high-volume, efficient and economical system for the publication of peer-reviewed research in all areas of science and medicine. It will provide a unique forum for community dialogue using the full potential of the web to accelerate scientific progress.
