Lesson 8 Reading and Writing Explanation and the Methodology I. Your Mini-talk II. The Text Types: Explanation Explanations are concerned with explaining how processes happen. “To this end they imply sequences of causes and effects” (Wignell, Martin & Eggins, 1993). 4 types of explanations: sequential explanation factorial explanation consequential explanation conditional explanation Schematic structure in explanation writing: 1) specifying the Phenomenon (effect/cause/issue) 2) the Explanation stage / the implication sequence causes / effects / sequence of events / conditions-effects 3) Extension / Implication / Significance / Recapitulation Important in explanation writing: Presence of Causality Logic and Thoroughness Implicit Causality --- absence of conjunctions Multi-modal Reports and Explanations 1. The Sequential explanation is typically constructed as a series of events. Logical relations between events are temporal, either succeeding each other in time or happening at the same time. 2. The Factorial explanation explains how an effect involves multiple factors. 3. The Consequential explanation explains how a single factor leads to multiple consequences. 4.

Differentiating types of explanation Ex. 8-1 Read the following texts, and determine which type of explanation they respectively are. Make sure that you identify factor-consequence relations in the particular type of explanation. Text 1 Predator and Prey
L8 Explanation&the Methodology Population size of one species can be affected by the size of the population of another species.This is true in the case of a predator species and the prey species on which it feeds.Over time,several outcomes are possible: If the predators are absent,the prey population will increase exponentially but will eventually crash'when its numbers become too high to be supported by the food resources in the habitat. If the prey population is too small,the predator population will starve and die. In some cases,cycles of boom-and-bust'can be seen in both populations,with the peak in the predator population occurring after the peak in the prey population. Why? (Kinnear Martin,2004) Text 2 The Mulga Tree How can plant life grow so well in such dry,hot and infertile places?The mulga tree likes long droughts-if it is too wet,mulga trees will not grow. The shape of the mulga tree is the key to its surviving dry times.The branches of the mulga fan out from the bottom-like a huge half-moon.The branching leaves and stem catch the rain and it trickles down to the soil.This traps more rainfall than if the tree grew straight up.The mulga catches more water than a gum tree.The water is stored in the soil to be used by the tree during the next drought. Even the mulga's leaves help it survive the drought.They are a silvery grey color. The sun's rays bounce off the leaves helping the plant to stay cool.Also the mulga tree makes its own food by dropping thousands of leaves. (Scott Robinson,1993) Text 3 What Causes and Transmits Sounds? Figure 15.1 shows a vibrating object producing sound waves.As the object moves to the right it pushes or compresses the air particles next to it.The compressed air particles then push on the particles to their right and compress them.As each air particle pushes on the next one to its right the compression travels through the air. When the vibrating object moves back to its left the air particles next to it are no longer being pushed.They spread out or are stretched apart.As a compression travels through the air it is followed by the stretching apart of air particles.Because the vibrating object continually moves back and forth a series of compressions and stretchings of air particles is sent out from the object.

L8 Explanation & the Methodology 2 / 10 Population size of one species can be affected by the size of the population of another species. This is true in the case of a predator species and the prey species on which it feeds. Over time, several outcomes are possible: If the predators are absent, the prey population will increase exponentially but will eventually ‘crash’ when its numbers become too high to be supported by the food resources in the habitat. If the prey population is too small, the predator population will starve and die. In some cases, cycles of ‘boom-and-bust’ can be seen in both populations, with the peak in the predator population occurring after the peak in the prey population. Why?

L8 Explanation&the Methodology Professor David Kennedy of Stanford University has argued that the cost and trauma of the Vietnam War produced a 'crisis of confidence'in the USA.Until the Vietnam War,Americans had generally felt confident in their ability to mould events through the exercise of their ingenuity,energy and vast economic resources.Vietnam proved to be a problem that they couldn't manage. The Vietnam conflict gave rise to social division and distrust of government in the US.It ended the political career of President Lyndon Johnson and his dreams of major social reform.It also produced,in the case of Richard Nixon's presidency,a siege mentality that contributed directly to the infamous Watergate Scandal (1973-74)and the resignation,in disgrace,of Nixon.Because of the Vietnam War, as part of the wider conflict in Indochina,a generation of Americans identified with anti -conscription and anti-war protest movements.Many of the social and political effects evident in the US were also present in Australia (Dennett Dixon,2003) Ex.8-2 Determine which type of explanation would most probably apply if your assignment is to write on the following topics. 1.What are the causes of increased obesity in the U.S.? 2.What would be the possible effects of the rising costs of college education? 3.What would possibly cause Americans having large credit card debt? 4.What impact does cyber bullying have on teenagers? 5.What would cause college students unable to manage their time well? 6.

Our findings provide partial experimental confirmation of these observations. Participants were less likely to successfully cross the street in our task when they were conversing on a cell phone than when they were listening to music on an iPod. Furthermore, engaging in a cell phone conversation while crossing the street led to higher time out rates in our virtual street-crossing task than did listening to music or performing the task distracted. Additionally, participants took more time to initiate a crossing when conversing on a cell phone, and walked more slowly during crossing.

L8 Explanation&the Methodology Methodology 1 The current investigation involved sampling and analyzing six sites to measure changes in groundwater chemistry.2 The sites were selected from the London Basin area,which is located in the south-east of England and has been frequently used to interpret groundwater evolution. 3 A total of 18 samples was collected and then analyzed for the isotopes mentioned earlier.4 Samples1-9 were collected in thoroughly-rinsed 25 ml brown glass bottles which were filled to the top and then sealed tightly to prevent contamination.5 The filled bottles were shipped directly to two separate laboratories at Reading University,where they were analyzed using standard methods suitably miniaturized to handle small quantities of water. 6 Samples 10-18 were prepared in our laboratory using a revised version of the precipitation method established by the ISF Institute in Germany.7 This method obtains a precipitate through the addition of BaCl2.2H2O:the resulting precipitate can be washed and stored easily. 8 The samples were subsequently shipped to ISF for analysis by accelerator mass spectrometry (AMS).9 All tubing used was stainless steel,and although two samples were at risk of CFC contamination as a result of brief contact with plastic,variation among samples was negligible.

Warm air rise in hot clouds and encounters cold air,charging the particles in the cloud making them both positive and negative charges,and this is called static electricity. When enough positive and negative charges occur,they build up too much energy and explode in a flash of light that we call lightening. This flash of light helps balance out the number of negative and positive charges in atmosphere. Sometimes the flash of light is movement within the cloud and sometimes it is lightening movement between the atmosphere and the ground. The movement between the atmosphere and the ground is the reason that tall objects on earth like trees are struck by lightning. Light travels faster than sound,and because of this,we see the flash of lighting before we hear the clap of thunder.There is a direct relationship between thunder and lightning;they are not separate phenomena. Thunder and lightning lasts only as long as is necessary to get all the electrical charges in the atmosphere back in balance.
