6 Population growth

Earlier it was stated that three factors check population growth. These are predation, disease and insufficient food supply. For much of our history, our ancestors’ numbers were indeed limited by wars, disease and famine. The world population remained relatively stable until around 300 years ago. Then at the beginning of the 19th century (100 years after population growth started its geometric increase), the demographer Thomas Malthus predicted that population growth would outstrip food pro

2.1 Trophic levels

'All flesh is grass'; this somewhat paradoxical biblical quotation really is only a restatement of what was more formally explained in previous units in this series. The materials needed by plant eaters (see course S182_4) for the growth of 'flesh' - by which I mean not just the meaty muscular parts, but all of the body - must come entirely from their plant food. Plants grow using the Sun's energy in the process of photosynthesis. Plants occupy the lowermost of a succession of feeding levels,

3.4 Systems concepts: structure

As suggested earlier, the structure of a system is its functional or physical arrangement; the term that is often used in systems engineering is ‘architecture’. The architecture of a system can be deconstructed to reveal its constituent elements. I suggested in Section 1 that an existing knowledge base has an important bearing on the way in which a change problem is perceived. The way that this is conceived by one armaments system integrator is illustrated in

7 Experiencing the exotic

So far we have looked in some detail at the interiors of Nash's Pavilion, with the important exception of the Banqueting Room (decorated by Robert Jones) and the Music Room (decorated by Frederick Crace). Both were designed as coups de theatre and it is this aspect of these rooms that I'd like you to focus upon now.

9.3 Linear notes

This is the most common form of note-taking. It involves writing in sequence the points you want to note. As with all note-taking, the aim is to pick out and record the most important points. Avoid simply writing out most or all of the text again.

Try to write your notes in your own words as this will help you understand what you have been reading about. Also add a reference to which page(s) of the text your notes refer so you can easily find your way back to the relevant part of the te

2.1 The importance of sine waves

For much of the rest of this unit we shall be concerned with the properties of a type of sound wave that when represented as a graph has a characteristic shape known as a sine wave. Figure 1 shows you what a sine-wave graph looks like. For the moment you need not be concerned with what this grap

Lecture 12: The Centenary Lubbock Lecture
Lord Browne of Madingley, President of the Royal Academy of Engineering "On being an engineer". As President of The Royal Academy of Engineering, Lord Browne's prime goal during his five years in office is 'to move engineering towards the centre of society'. In his opinion the words 'engineers design the future' have more resonance today than ever before. Drawing on global experience of the energy business, industry and political life Lord Browne reflected on what being an engineer means in the

Water in Ethiopia
In Ethiopia, 65% of people don’t have access to clean drinking water. In this album we take a glimpse at the struggles Ethiopians go through each day, just to survive. We look closely at the different methods used to improve the quality of life in the rural highlands as well as the conflict between neighbouring farming villages attempting to share the same water supply.

1.5.2 Metamorphic recrystallisation

To consider metamorphic recrystallisation at its simplest, let's begin by imagining a sedimentary rock composed entirely of quartz grains – a quartz sandstone. Sandstone is a sedimentary rock and so has a fragmental texture (see Figure 7b). When it is subjected to high temperature and high pressure

1.1 The Earth's crust

On the scale of a human lifetime, these rocks and the landscapes of which they are part can seem static and immutable, at least in a country such as Britain where there are no active volcanoes, and earthquakes are infrequent and fairly small. None the less, coastal erosion and the biological degradation of rocks to form soils are reminders that geological processes are occurring ‘in our own backyard’ and that the Earth's surface is continuously being reshaped.

Conclusion

This course started by asking simple questions such as ‘what science to teach?’ and ‘what is science?’ and pursued them to the point where answers proved both complex and elusive. Much of what I've said about such issues has been in the context of UK science education, though you'll be aware (e.g. see the Fensham reading) tha

12 Science in secondary schools

The first three readings in this course use the context of secondary education, particularly in the UK and Australia. In this section, I'll be looking again at the issues highlighted in the previous section on primary science and drawing comparisons with experiences in secondary schools; I'll re-visit much the same issues when I consider post-compulsory science education in Author(s): The Open University
