How to Qualify for a National Merit Scholarship With a PSAT
A standardized test prep instructor explains how to qualify for a National Merit Scholarship using the PSAT. He explains that juniors in high school will need to submit their scores and then submit
their SAT scores as finalists before writing an essay and submitting
grades and a course list. (01:45)
Introduction to differentiation
This free course is an introduction to differentiation. Section 1 looks at gradients of graphs and introduces differentiation from first principles. Section 2 looks at finding derivatives of simple functions. Section 3 introduces rates of change by looking at real life situations. Section 4 looks at using the derivative of a function to deduce useful facts for sketching its graph. Section 5 covers the second derivative test, used to determine the nature of stationary points and ends by looking a
2.1 Resisting a body–mind–social split To what extent are you your body? The seventeenth-century philosopher René Descartes saw human subjective experience (including rationality, thought and spirituality) as separate and fundamentally different from the objective world of matter, that of our bodies and the physical universe. This idea of a fundamental divide between mind and matter (as two different kinds of ‘stuff’) set the stage for centuries of debate on what came to be known as Cartesian dualism. Critics of this w
How to Find the Perimeter of a Triangle
This is a very brief tutorial that focuses on solving the perimeter of a triangle. The teacher uses a small whiteboard for instruction. (01:51)
4.2 Social dynamics Yet another type of diagram is given in this section. Take a preliminary look at Figure 7, which is a way of illustrating the relationship Introduction Many people have the impression that underground water occupies vast caverns, such as those in the Derbyshire Peak District, flowing from one cavern to another along underground rivers. This is a common misconception: underground caverns are fairly rare, but huge quantities of water exist underground, within rocks. This is because many rocks contain pores, spaces that come in all shapes and sizes. In sediments, and consequently sedimentary rocks, there are often pores between grains which can Model of tetragonal perovskite structure Winning Resources and Support Keep on learning There are more than 800 courses on OpenLearn for you to choose fro Keep on learning There are more than 800 courses on OpenLearn for you to choose from on 1 Introduction to the course Scientists are increasingly being asked to discuss and communicate social and ethical issues that arise from their work. Understanding these issues is also part of developing science and technology responsibly. And yet the formal education system in the UK often requires scientists to focus on core science subjects at the expense of learning about the social and ethical implications of their work. How then does a modern scientist begin to engage with these important issues? One solution is to 3.9 News sources Many news sources are now available online. Searching an online version of a newspaper is easier, quicker and more effective than searching through printed indexes, microfilm or actual newspapers. 3.7 A note on straight-line graphs and their gradients We end this section by reviewing some of the important features of straight-line graphs, though we do so in terms of two general variables z and y, rather than x and t, in order to emphasise their generality. If the graph of z against y is a straight line of the kind shown in Figure 22, then z and y are related by an equation of the form 1.2.2 Summary The results of successive editions of the Eurobarometer show that in most EU countries only a very small percentage of people, around 5 per cent, declare having an exclusive European identity, while up to 50 per cent do not have any sense of European identity. European political identity is weak and there is a great variation across states. 7 Course questions Now you have completed this course, try the following questions to test your understanding of this material. Like the Variscan Orogenic Belt, the Caledonian includes large granitic intrusions. Using 5.7.2 Elimination of pathogens through solar disinfection The lack of safe drinking water in many developing countries has prompted research into simple methods of disinfecting small quantities of water. One such investigation at the University of Beirut in the Lebanon revealed that 99.9% of total bacteria in a water sample could be destroyed by 300 minutes exposure to direct sunlight. In effect this means that if you left a sample of water in a translucent container, a lot of the bacteria in it would be killed. Research to date has concentrat Season 3 – Lesson 03 – Coffee Break Spanish This lesson was originally released in October, so in lesson 3 of Show Time Spanish, Alba tells Mark about a Halloween party she attended. They discuss the traditions of Halloween. In the intermedio José provides two alternative ways to say that you’re tired. Grammar points include reflexive verbs in different tenses, the subjunctive after quizás.  Not the most seasonal of lessons, but lots of interesting Spanish! Please note that lesson 03 Season 3 – Lesson 23 – Coffee Break Spanish This week Mark and Alba bring you a special musical episode: combining the Eurovision Song Contest with a performance from Mark of Tango by Spanish composer Albéniz. In the intermedio, José introduces the idea of ’embarrassment’ – vergüenza – and gives listeners some examples of how to use this concept in interesting expressions. Language points covered include llevar + time in the negative to talk about what you haven’t done for a Acknowledgements The content acknowledged below is Proprietary (see terms and conditions) and is used under licence.
