Discover the world's most endangered species Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.
PROFILES - UCC Cork Scientific literacy enables all citizens to play an active role in decision-making concerning scientific and technological issues. In order to develop scientific literacy, science teachers need to promote the development of scientific knowledge and competences for analysing the consequences and problems related to rapid scientific and technological growth. The goal of this module is to enable students to learn about organ donation and to develop an ability to apply their knowledge and understanding so that they are to make an informed evaluation of the bioethical issues involved in meeting the demand for organs. The subject of organ donation is highly sensitive and should be handled with care. The module aims at promoting thinking competences, attitudes and values that enable students to play a constructive, participative and responsible role in society. There is currently a severe global shortage in the number of donor organs available for transplantation.
Practical Biology This website is for teachers of biology in schools and colleges. It is a collection of experiments that demonstrate a wide range of biological concepts and processes. Experiments are placed within real-life contexts, and have links to carefully selected further reading. Biology is a practical science. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. Unfortunately, we are unable to respond to questions from teachers, technicians or students on how to use the experiments on this website. Building a seismograph from scrap By Panteleimon Bazanos Some earthquakes may be so slight as to be practically unnoticeable, but they can still be recorded. Each tremor produces different types of vibration, or seismic waves, which travel through Earth’s interior with different velocities. These waves can be detected and recorded by instruments called seismographs, which are often sited at great distances from the earthquake. By measuring the time that the seismic waves take to arrive at seismographs, as well as recording the amplitude and duration of the waves, we can calculate the magnitude of the earthquake and determine its epicentre. Monitoring local earthquakes Earthquakes are a daily occurrence in Greece (figure 1), sitting as it does at the boundary of two tectonic plates.
