DNA Extraction Lab (Peas)
Video of the procedure for extracting DNA from dried split peas. Each step is explained in detail. Could be used as a pre-lab video to show students teacher preparation of the lab to help illustrate the process. This video uses lecture format (for background information) as well as a lab demonstration. Color and sound 7:43 min.

1.2.1 The EU economy Just to put things into perspective and remind ourselves of some basic background features of the EU, it is useful to provide an outline picture of the size of the EU compared to the USA and Japan. While a lot is made of the rise of China and India as potential competitors to these and other economies, as yet they remain rapidly expanding economic giants whose main impact will probably arise in the next decade. Comparative data on these two economies, and on the EU-12, the USA and Japan, is g
Something About Mary Magdalene 3 (of 5)
'Something About Mary Magdalene' looks at the role of Mary Magdalene through history and highlights recent evidence concerning her role in the church and today's society. Use this documentary to learn -- information contained in the documentary does not have to interfere with one's faith. It is NOT meant to be inflammatory but informative.
8.1.1 Visibility Recall that a key usability design feature identified by Donald Norman – from his analysis of using everyday objects such as doors – was visibility. An everyday object such as a door, or a control such as a button on a product should appear to be obvious about how it is used, and indeed it should perform that obvious function. For example, is it obvious how you insert a disc into a player? Is it obvious how you switch the machine on, adjust volume, and so on?
7.2 Developing a strategy Present notes/records to show you have planned to use skills to improve your learning and performance. Include: A review of your current capabilities and your goals over an extended period of time (at least three months). Indicate how your goals relate to the context in which you are working and your current capabilities. Your evidence could include a skills audit based on the key skills criteria and other criteria given as part of your course
1.2.2 Chemical contraceptives These methods rely to a large extent on an understanding of the physiology of the reproductive process. They are targeted at preventing the production or release of gametes, i.e. the sex cells – sperm and eggs – which need to fuse to produce a new individual. To date, most effort in this area has been directed towards preventing a woman from ovulating, i.e. releasing an egg, although more recently trials have begun on ‘male pills’ which block sperm production. Ovulation i
Conquering Technophobia: A Classroom Veteran Warms to Digital Tools
Jim Wilson, a self-described "old guy" and star of theEdutopia video Conquering Technophobia, has gone from grumbling about his school's technology-integration initiative to embracing it. Laptop computers and other gadgets are now tools that he uses just about every day in his English classes at Freedom Area High School, outside Pittsburgh.There have been bumps along the way, and -- Wilson will be the first to tell you -- there are surely more to come. But he's pleased with what comput
Partnerships: working across boundaries
How much more can you achieve by working with others rather than working alone? How should you manage relationships across various physical and cultural divides? This album explores how the formation of a variety of partnerships, spanning public, private and voluntary sectors, has radically regenerated the City of Stoke-on-Trent in the UK, bringing major improvements for the city’s physical and social environments. A second case study features Medecins Sans Frontieres (Doctors without Borders)
Narconomics: How to run a drug cartel
Tom Wainwright, The Economist's Britain editor and former Mexico correspondent, explores the parallels between the $300 billion illegal drugs business and the corporate world, from franchising to corporate social responsibility
1.2.1 Rounding to the nearest hundred You will probably think to yourself that the coat shown costs about £300. £290 is considerably closer to £300 than it is to £200, so £300 is a reasonable approximation. In this case, 290 has been rounded up to 300. Similarly, 208 would be rounded down to 200 because it is closer to 200 than it is to 300. Both numbers have been rounded to the nearest hundred pounds. When rounding to the nearest hundred, anything below fifty rounds down. So 248 rounds to 200. Anything o
1.4.5 M is for Method Method is about the way in which a piece of information is produced. This is quite a complex area as different types of information are produced in different ways. These are a few suggestions to look out for: Opinions - A lot of information is based on the opinion of individuals. They may or not be experts in their field (see P for Provenance) but the key message is to be clear that it is just an opinion and must be valued as such. Research - You don't have to be a
2.6 Division of complex numbers The second of the conjugate–modulus properties enables us to find reciprocals of complex numbers and to divide one complex number by another, as shown in the next example. As for real numbers, we cannot find a reciprocal of zero, nor divide any complex number by zero. Introduction This unit is from our archive and it is an adapted extract from Human biology and health (SK220), which is no longer in presentation. If you wish to study formally at The Open University, you may wish to explore the courses we offer in this curriculum area. To be able to understand the importance of the environment for our health, we n How Sunburns Work - How Stuff Works The Food Chain 2.5 Wavelength So far we have seen that sound is a pressure wave, and that the spacing of the pressure variations is related to the period of vibration of the source. A graphical representation of the pressure wave from a tuning fork closely approximates to a certain type of wave known as a sine wave. If we freeze the pressure wave as a snap shot in time, the variations in pressure with distance from the tuning fork can be plotted as a sine wave. The vertical axis is pressure so the crest 2.2.1 Try some yourself Here is a poor example of mathematical writing, although the final answer is correct. Rewrite it, correcting the layout and the mathematical punctuation.

Why do some people tan, and others burn? Learn why skin works the way that it does. Explains what happens after your skin gets too much sun. Grades 5-12. (00:58)
A dragon puppet explains the basics of the food chain and food web. The explains and gives examples of many vocabulary words from a food chain, including producer, consumer, carnivore, herbivore, omnivore and decomposer. The puppet also discusses "chain reactions" - what happens when you remove an item from a food chain. The end of the video ties it all together with food webs. Run time 6:40
