Under the Spell of ... Spiders!
Spiders are endlessly fascinating and a great school subject because they offer plenty of teachable topics that span the curriculum. We've tried to provide some of those topics here in these lessons, as for all their amazing physical features and unusual habits, spiders, with just a few notable exceptions, pose little threat to humans and are creatures deserving of understanding and respect. It's our hope that, as you work through the activities, your students will gain a new appreciation for sp
Streams in the City
These exercises are designed to guide a student to an understanding of how rainfall and storm events result in runoff over the surface of the earth. Runoff is influenced by the nature of the surface of the earth. Streamflow is particularly influenced by urbanization-the paving over of permeable surfaces with impermeable ones. In light of this, students are encouraged to think about design elements that incorporate more permeable surfaces into their own environments, including their school parkin
In this set of exercises, students will study rivers and waterways around them by using the Internet, maps, and their knowledge of local landscapes. The students will use an EPA Web site to investigate what is upstream and downstream of them. They will also look at graphs of flow in familiar river locations on a live U.S. Geological Survey Web site. Using small rocks and a washbasin, students will build a model that leads to extending their understanding of streams in different geographic locati
Aquifer on the Go
This demonstration should follow a class discussion on potential sources of pollution to drinking water supplies. To illustrate how water is stored in an aquifer, how ground water can become contaminated, and how this contamination ends up in a drinking water well. Ultimately, students should get a clear understanding of how careless use and disposal of harmful contaminants above the ground can potentially end up in the drinking water below the ground. This particular experiment can be done by e

Doctors in a Divided Society: The Profession and Education of Medical Practitioners in South Africa
Many of the goals of South Africa's new democracy depend on the production of professionals who have not only the knowledge and skills to make our country globally competitive but also a commitment to working and living here. Despite numerous reforms, the South African health system, ten years into democracy, remains divided with first world private care that ranks with middle income countries internationally at the one end and at the other extreme in the rural public sector in particular condit
Clinical Skills Examination Procedures: Afrikaans & Xhosa
Shown here are a single set of techniques which are both simple to employ and reliable for four examinations. General Examination: preparing the patient for examination; describing the patient's appearance; examination for features of specific illnesses; taking the pulse; assessing warmth, perfusion, hydration and temperature; inspecting the hands, eyes, mouth and pharynx; looking for lymphadenopathy; and inspecting the legs. Abdominal Examination: preparing the patient for the examination; look
An Introduction to Information Systems
This resource provides a useful backdrop on political communication, journalism and national development issues as priority areas for collaborative action in Africa and the Middle East. This course provides a business perspective of information systems and stresses how information systems can be used to improve their planning and operation. The nature and value of information, as well as the impact of Internet technology on organisations and society are also considered.

Understanding management: I'm managing thank you!
This unit provides you with a set of ideas for developing your approach to managing your own work – what we might call ‘self-management’. In order to do this, we will examine some of the key processes of management decision making – allocating time, staff, physical and financial resources: prioritising and problem solving and monitoring performance.
The role of diagnosis in counselling and psychotherapy
This unit explores the role of diagnosis in the treatment of mental health problems. It considers the history of our current understandings of 'mental health' and 'illness' with focus on the concepts of anxiety and depression, and looks at potential gains and losses in using diagnostic labels in counselling and pyschotherapy.
Knowledge in everyday life
This unit is designed to help those working with children between the ages of 3 and 8. You will be encouraged to explore your knowledge, feelings and attitudes in language, mathematics and science in order to understand the place that these subjects have in the life of both individuals and society as a whole.
Butterfly pupa anatomy
The pupa is the third stage of the butterfly's life cycle. The caterpillar creates a pupa, sometimes called a chrysalis, and emerges as the adult butterfly after metamorphosis. The butterfly's wings will be used for flying.
Buffalo grazing on Wyoming prairies
Grasslands are found where rainfall is low and temperatures are extreme. Grasslands experience drought and occasional fires. The soil of grasslands is deep, moist, and nutrient rich from dead grass and other organisms, which is good for agriculture.
Blood flow of moving Lumbriculus
Observe blood flow and muscle contractions in each body segment of Lumbriculus variegates (note how blood flows in relation to the worm turning in the capillary tube).
Birds' beaks: a special adaptation
The size and shape of a bird's beak is telling of its diet. Bird's beaks are special adaptations to get food and vary according to if the bird eats plants, animals, or seeds.
Most birds make homes called nests. They are built out of twigs, hair, bits of trash, mud, and many other items. Many birds build these nests in tree branches, but they can also be built on the ground or on buildings such as rooftops.
Bee on flower
Bees visit flowering plants to collect nectar so they can store it as honey back at their hives. As a bee visits one flower after another, pollen collects on its entire body and especially on the legs. Bees help pollinate flowers while they collect nectar. This is a mutualistic behavior.
Balance and flux
Ecosystems and populations of organisms within ecosystems function by the principle of balance and flux. Balance can be thought of as a state of equilibrium, or a state of equal changes between two sides. Flux can be thought of as a rate of flow or changes. Even small changes in an ecosystem's or population's balance and flux could lead to disaster.
