Kõrv loodusesse - loodushelid ja helid looduses
Loodushelid ja helid looduses. Veebilehed info ja illustratsioonidega vastavatest liikidest, võimalik kuulata helindeid. Kõrv loodusesse kasutab kahte erinevat kokkusurutud helifaili formaati: mp3 ja real audio. Üldjuhul võimaldab mp3-formaat paremat kvaliteeti, kuid faili maht on suur. Real audio on väiksema failimahuga, kuid sellega kaasneb kehvem kvaliteet. Aeglase ühenduse korral on seetõttu otstarbekam valida real audio helindid. Kiirema ühenduse korral tasub kuulata parema kvalitee
Calisphere Themed Collection - 1870-1900: Closing of the Frontier: Everyday Life and People
The images in this topic show how Californians in the late 19th century worked and played. Many of these photographs reflect the manual labor (mining, logging, agriculture) and services (like barber shops and grocery stores) that supported the rapid growth of cities and towns. As they do today, people spent their free time doing quiet activities like painting, enjoying themselves outdoors, riding bicycles and camping.
Calisphere Themed Collection - 1780-1880: California in Transition: Rich Resources
These images show the importance of both California's natural and human resource potential to the state’s development and subsequent wealth. Natural resources like water, lumber, and oil — along with human-driven resources like transportation, agriculture, and technology — have all contributed to California's growth. These natural resources drew many different ethnic groups to the state: human resources that would construct railways and aqueducts, plant crops and harvest them, strike it ri
Cleaner Energy Cooler Climate: Developing Sustainable Energy Solutions for South Africa
For South Africa, finding a policy approach that balances the increasing demand for energy with the need for sustainability, equity, and climate change mitigation is a particular challenge. Through energy modelling indicators of sustainable development and policy analysis, Harald Winkler builds a rich and detailed case study illustrating how a development-focused approach to energy and climate policy might work in South Africa. Moreover, with recent recordsetting global crude oil prices, he poin

Starting with psychology
The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts. When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’
7 Next steps
We all know that the heart is very important but what exactly does the heart do? Why is the blood so important? What functions do the lungs perform? In this unit, we will try to provide at least a basic understanding so we can answer these questions and begin to understand why knowing about the heart is important for all sports people. Before that we will take a look at the human body.
Biotic Indices of Stream Macroinvertebrates for Fun and (Educational) Profit
Water quality monitoring activities can support student inquiry into ecological concepts and pollution issues, as well as offer insight into integrating field and lab work. This exercise provides students with practice in identification (to order or family level) of stream macroinvertebrates that they've previously collected. Provided information indicates water pollution tolerance of the various taxa. Students use the data to calculate several different biotic indices for the macroinvertebrates
Building Molecular Models of DNA, Protein, and Lipids
Molecular models of DNA, protein (alpha-helix and beta-pleated sheet), and lipids are built to scale. With a minimum of scientific jargon, these laboratory exercises effectively display the important aspects of three-dimensional shape and spatial orientation that are poorly presented in textbook illustrations and demonstrate how the shape of molecules and weak chemical associations like hydrogen bonds and hydrophobic/hydrophilic interactions combine to form the macromolecular associations fundam
Regulation of Blood Glucose Levels in Normal and Diabetic Rats
This exercise demonstrates the crucial role insulin plays in blood glucose homeostasis in mammals. Three pairs of fasted rats are tested in each of three different regimes; one rat of each pair is normal and the other is diabetic. The first pair is administered an oral glucose load and a placebo injection of saline. The second pair is administered an oral glucose load and an insulin injection. The third pair is administered an oral placebo of water and a placebo injection of saline. The blood gl
Moral and ethical principles in end of life care
In many areas of health care, and especially in such areas as palliative care, increasing attention has been paid in recent years to patient autonomy, and the need to respect it. Autonomy has come to be seen as a very important aspect of the interaction between patients and those looking after them, and forms the basis for many ethical commitments, such as telling the truth to patients, and seeking their consent for health care interventions. In this unit we look at quite a wide range of ethical
Boy on trampoline
The boy would feel less secure if the safety net around the trampoline wasn't there. Humans have an innate need to feel secure in their environments.
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.
Artemia blood circulation
Artemia blood circulation in the head and around the gut.
Human arm muscles are connected to the bones by things called tendons. Tendons are rope-like fibers that join muscles to bones and allow movement.
One reason why ticks are considered to be arachnids is because they do not have antennae like insects do. Ticks suck blood from animals and are sometimes difficult to remove from the host's skin.
Apple Screen 1
The apple has just fallen from the tree and rests on the ground.
Roots can grow in multiple directions. Just because this plant was in a cup didn't stop the roots from growing longer and creating individual branches.
Land snails are invertebrates because they do not have a backbone. They are related to water snails, but they do not live in water.
