The Big Moon Illusion
Why does the moon appear large while it is on Earth's horizon? Several possibilities are explained here.(01:24)
How to do Long Division
Dr. Shah teaches the viewer, with the aid of a whiteboard, how to do long division. The instructor does two complete problems. These problems consist of a four-digit number divided by a two-digit number. (04:46)
Chinese Foot Binding
A five minute video based on comments from a Chinese woman who went through this practice. A powerful video with good images. The images may be to graphic for some. A good video that shows how the pressures of culture can produce practices that may not be healthful. A great way to introduce other cultural practices from around the world and to decide if they are beneficial.
The story of India
This five minute video. It briefly deals with some of the history of India and has excellent graphics. The problem is that it is essential a trailer for a longer video and thus offers just tidbits of history and geography. At best an introduction into the study of this country. Ends abruptly.

OptometrÃa II (2010)
La asignatura OptometrÃa II deriva de la materia troncal OptometrÃa y ContactologÃa (B.O.E. 20-11-1990), correspondiéndole un total de 8 créditos (3,5 teóricos y 4,5 prácticos). El alumnos debe tener unos conocimientos básicos teóricos y prácticos de las ametropÃas y de los principios de la evaluación, detección y corrección óptica de las disfunciones refractivas (OptometrÃa I, que se imparte en el primer cuatrimestre de segundo curso), y debe sentar las bases para el aprendizaje
Identitat, mitjans de comunicació i testimonis
Ho va deixar escrit el reporter Ryskard Kapuscinki: "Es diu que els mitjans són el quart poder, però jo apujaria el seu lloc en el rà nquing. Ja sabem que el seu paper en la polÃtica és cada vegada més rellevant i que ha fet que insurrectes i colpistes de tota mena canviessin l'objectiu dels seus atacs a tot el món: abans assetjaven palaus presidencials i seus de governs i parlaments, mentre que ara intenten fer-se en primer lloc amb el control de les emissores de rà dio i televisió. No d
Recepció i promoció del llibre i la lectura en la societat de la informació
La vida d'un text comença (no acaba) en el moment en què es publica. Aquesta assignatura proposa una aproximació al fenomen de la recepció i la promoció del llibre, la literatura i la lectura en la societat de la informació i combina la presentació de continguts teòrics -sobre les tecnologies de la lectura, els contextos digitals de recepció, les funcions de la crÃtica a Internet, les campanyes institucionals de promoció del llibre, el problema de la digitalització o les biblioteques
Photosynthesis: Life's Primary Energy Source
This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a complex yet efficient process for converting solar energy to chemical energy or distributing water throughout a system.
Trash to Treasure!
Student teams use the engineering design process to create a useful product of their choice out of recyclable items and "trash." The class is given a "landfill" of reusable items, such as aluminum cans, cardboard, paper, juice boxes, chip bags, egg cartons, milk cartons, and etc. and each group is allowed a limited amount of bonding materials, such as duct tape, hot glue and string. This activity addresses the importance of reuse and encourages students to look at ways they can reuse items they
Glowing Flowers
Student teams learn about engineering design of green fluorescent proteins (GFPs) and the use of GFPs in medical research, including stem cell research. The use of GFPs is simulated by adding fluorescent dye to water and allowing a flower or plant to transport the dye throughout its structure. Students apply their knowledge of GFPs to engineering applications in the medical, environmental and space exploration fields. Due to the fluorescing nature of the dye, plant life of any color, light or da
The Cloning of Cells
In this lesson, students continue their education on cells in the human body. They discuss stem cells and how engineers are involved in the research of stem cell behavior. They learn about possible applications of stem cell research and associated technologies, such as fluorescent dyes for tracking the replication of specific cells.
Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.
Sliders (for High School)
In this hands-on activity, students learn about two types of friction static and kinetic and the equation that governs them. They also measure the coefficient of static friction and the coefficient of kinetic friction experimentally.
Skateboard Disaster
Students examine collisions between two skateboards with different masses to learn about conservation of momentum in collisions.
3.5.1 IPv4 Addresses The allocation of addresses on the Internet is controlled by the Internet Assigned Numbers Authority (IANA), although authority is delegated to several local registries. IPv4 addresses may be interpreted in two ways. Initially, they were divided into distinct ranges of addresses called classes, but this proved to be inflexible and now a more flexible scheme, called classless addressing, dominates IPv4 internetworks. I shall describe both ways of interpreting IPv4 addresses because the limitat
Lock and Key Hypothesis
Introducing the "lock and key" analogy of drug-receptor interaction, whereby only drugs of a certain molecular shape will 'fit' with a cell membrane receptor.
Live like an Animal
In this activity, students design an innovative human shelter that is inspired and informed by an animal structure. Each group is assigned an animal class, and they gather information about shelters used by the animals in that class. After researching the topic and brainstorming ideas, students build small prototypes (models) of the structures. Finally, they present their products, explaining what attribute of the animal structure influenced their design.
2.1 What is a complex number?
Number systems and the rules for combining numbers can be daunting. This unit will help you to understand the detail of rational and real numbers, complex numbers and integers. You will also be introduced to modular arithmetic and the concept of a relation between elements of a set.
