Using Ion Exchange Chromatography to Separate Proteins
This activity website, hosted by the National Health Museum Activities Exchange, explores protein purification using ion chromatography. Students will separate a positively charged lysozyme from a negatively charged albumin at a neutral pH using ion exchange chromatography. The site includes information for the teacher, instructions and follow-up questions for students, and a list of supplies.
Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan. In the course of this curriculum students locate the biome in which they live, explore a local habi
Gulf Coast Geology
This website is part of the Environmental Protection Agency's Gulf of Mexico Program. The program includes projects encompassing everything from improving septic systems to planting seagrass to protecting habitats. All projects aim to improve the ecological and economical health of the region. The site provides information about Gulf Coast geology as well as links to information about the Ice Age.
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

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
