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.
3.1a Working on the key skill of improving own learning and performance Improving learning and improving your performance may sound simple enough, but experienced learners know that there is not always a direct route from a particular learning experience to improved performance. Many factors can affect this link – motivation, resources, support and feedback. You need to acknowledge that these, and many other factors, can and do influence the outcomes of your efforts. In other words, many influences can come along to knock learning off track. It is also importan

Experimental Design and Testing: Hatching and Development in Brine Shrimp
This scientific investigation uses hatching and development in brine shrimp as the biological system in which to demonstrate the laboratory model of teaching experimental design.
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.
2.11 Further exercises
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.
4.1 Scientific approaches
Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. This unit builds on and develops ideas introduced in the
Pathway 2 Information: Citing References
The citing and referencing module is part of a wider online tutorial designed to teach a range of information skills to undergraduate students. The module aims to provide an introductory guide to why referencing and citing is important and how to reference particular types of material according to different referencing styles. This skill is required by students throughout their degree courses and backs up more traditional face-to-face teaching in this area. The module uses an interactive approa
The effect of hunger on children and graphing
Following are a series of activities in which students apply various math skills to better understand the problems of world hunger and what steps are being taken to reduce the number of people without enough to eat. This activity examines the effect of hunger on children and the connection with child mortality, which is another MDG Hunger Target: Halve, between 1990 and 2015, the proportion of people who suffer from hunger. Child Mortality Target: Reduce by two-thirds, between 1990 and 2015, the
Contracting and Signaling, Winter 2008
Course prepares you to advise clients or your own organization on the design of contracts and screening policies when one of the parties has an information advantage over the other. For example, students study the design of patent licenses (the licensor knows more about the market), the design of social systems to reduce spam (the spam sender knows more about the content before the recipient decides whether to read), and the design of performance contracts for professional services (e.g., consul
Quantitative Skills Assessment of Geoscience Courses
The importance of quantitative skills in earth science education is the primary subject addressed by this website. This website is not a quantitative course, however this document does provide numerous useful techniques that can be employed in a variety of other coursework to advance the quantitative skills of the student. The first section of this website presents a checklist that can be used to develop exercises which will focus on specific quantitative applications and evaluations. Skills add

Simon Says Big Amplitude, Small Wavelength!
In this activity, students play the game Simon Says to make the amplitudes and wavelengths defined by the teacher. First they play alone, and then they play with a partner using a piece of rope.
Manufacturing Technologies: Making a Picture Frame
The goal of this activity is to demonstrate the basic processes involved in a manufacturing system while producing your own picture frame.
MRI Safety Grand Challenge
This module was written for a first year accelerated or AP physics class. It is intended to provide hands on activities to teach end of the year electricity and magnetism topics including the magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's Law, and Faraday's Law. During the module, students utilize these scientific concepts to solve the following problem: A nearby hospital has just installed a new Magnetic Resonance Imaging facility, which has the capacity to make a th
There is increasing recognition that the reductionist mindset that is currently dominating society, rooted in unlimited economic growth unperceptive to its social and environmental impact, cannot resolve the converging environmental, social and economic crises we now face. The primary aim of this unit is to encourage the shift away from reductionist and human centred thinking towards a holistic and ecological worldview.
