Respondents to the survey noted that many of their olfactory likes and dislikes were based on emotional associations. Such associations can be powerful enough so that odours that we would generally label unpleasant become agreeable, and those that...
The perception of smell, therefore, consists not only of the sensation of the odours themselves, but of the experiences and emotions associated with them. B Odours are also essential cues in social bonding. One respondent to the survey believed that...
The reason often given for the low regard in which smell is held is that, in comparison with its importance among animals, the human sense of smell is feeble and undeveloped. While it is true that the olfactory powers of humans are nothing like as fine as those possessed by certain animals, they are still remarkably acute. Our noses are able to recognise thousands of smells, and to perceive odours which are present only in extremely small quantities. D Smell, however, is a highly elusive phenomenon. Odours, unlike colours, for instance, cannot be named in many languages because the specific vocabulary simply doesn't exist. Nor can odours be recorded: there is no effective way to either capture or store them over time In the realm of olfaction, we must make do with descriptions and recollections. This has implications for olfactory research.
E Most of the research on smell undertaken to date has been of a physical scientific nature. Significant advances have been made in the understanding of the biological and chemical nature of olfaction, but many fundamental questions have yet to be answered. Researchers have still to decide whether smell is one sense or two - one responding to odours proper and the other registering odourless chemicals in the air. Other unanswered questions are whether the nose is the only part of the body affected by odours, and how smells can be measured objectively given the nonphysical components. Questions like these mean that interest in the psychology of smell is inevitably set to play an increasingly important role for researchers. F However, smell is not simply a biological and psychological phenomenon. Smell is cultural, hence it is a social and historical phenomenon. Odours are invested with cultural values: smells that are considered to be offensive in some cultures may be perfectly acceptable in others.
Therefore, our sense of smell is a means of, and model for, interacting with the world. Different smells can provide us with intimate and emotionally charged experiences and the value that we attach to these experiences is interiorised by the members of society in a deeply personal way. Importantly, our commonly held feelings about smells can help distinguish us from other cultures. The study of the cultural history of smell is, therefore, in a very real sense, an investigation into the essence of human culture. Write the correct letter in boxes on your answer sheet.

I think the link is that the large sized ears of animals can collect more sound waves which make their hearing power stronger than ours. For this activity find a quiet place in your school. Tell one of your friends to stand at a short distance and ask him to say something softly. The rest of you should listen carefully. Then all of you put your hands behind your ears, as shown in the picture.
Let the same child say something again as softly as before. In which case was the sound sharper? Ask your friends too. I could hear a sharper voice with my hands behind my ears. Put your hands over your ears and say something. Can you hear your own voice? Yes, I can hear my own voice. Sit near a desk. Tap the desk once with your hand. Listen carefully. Now put your ear on the desk as shown in the picture. Tap on the desk once again with your hand. Listen again. Was there any difference in the sound of the tap? Yes, when I put my ear on the desk I could hear a sharper sound of the tap. Which animals? Which ones? Page No 10 Sleeping and Waking i Have you noticed that during the cold season you cannot see any lizard in the house?
Where do you think they have gone? Yes, I have noticed that lizards are not seen during the cold season. I think they must have gone for long sleep at a warm place to escape cold. Given here is the sleeping time of some animals. Below each picture write for how many hours a day that animal sleeps. Here each circle is divided into 12 equal sectors. As a day has 24 hours, so sector is taken equal to 2 hours. For Cow: No. And yet, today tigers are in danger. What do you think are some of the dangers to tigers in the jungle? Besides this deforestation is causing tigers to lose their natural home and making their survival tough. Human beings kill animals for hide and other body parts.
Also forests are being destroyed to develop industries and build homes due to which the natural habitat of animals is reduced. What we have learnt i Have you noticed that sometimes singers put their hand on their ear when they sing? Why do you think they may be doing this? They do this to listen to their own voice and have control on it. Moreover, these books are written in accordance with the CBSE syllabus prescribed for class 5 students.
Paragraph G Bird Migration A. Birds have many unique design features that enable them to perform such amazing feats of endurance. They are equipped with lightweight, hollow bones, intricately designed feathers providing both lift and thrust for rapid flight, navigation systems superior to any that man has developed, and an ingenious heat conserving design that, among other things, concentrates all blood circulation beneath layers of warm, waterproof plumage, leaving them fit to face life in the harshest of climates. Their respiratory systems have to perform efficiently during sustained flights at altitude, so they have a system of extracting oxygen from their lungs that far exceeds that of any other animal. During the later stages of the summer breeding season, when food is plentiful, their bodies can accumulate considerable layers of fat, to provide sufficient energy for their long migratory flights. The fundamental reason that birds migrate is to find adequate food during the winter months when it is in short supply.
This particularly applies to birds that breed in the temperate and Arctic regions of the Northern Hemisphere, where food is abundant during the short growing season. Many species can tolerate cold temperatures if food is plentiful, but when food is not available, they must migrate. However, intriguing questions remain. One puzzling fact is that many birds journey much further than would be necessary just to find food and good weather. Another mystery involves the huge migrations performed by arctic terns and mudflat-feeding shorebirds that breed close to Polar Regions. In general, the further north a migrant species breeds, the further south it spends the winter. For arctic terns, this necessitates an annual round trip of 25, miles. Yet, en route to their final destination in far-flung southern latitudes, all these individuals overfly other areas of seemingly suitable habitat spanning two hemispheres.
One of the greatest mysteries is how young birds know how to find the traditional wintering areas without parental guidance. It is mind-boggling to consider that, once raised by its host species, the young cuckoo makes its way to ancestral wintering grounds in the tropics before returning single-handedly to northern Europe the next season to seek out a mate among its kind. The obvious implication is that it inherits from its parents an inbuilt route map and direction-finding capability, as well as a mental image of what another cuckoo looks like. Yet nobody has the slightest idea as to how this is possible. Mounting evidence has confirmed that birds use the positions of the sun and stars to obtain compass directions. However, accurate navigation also requires an awareness of position and time, especially when lost.
Experiments have shown that after being taken thousands of miles over an unfamiliar landmass, birds are still capable of returning rapidly to nest sites. Most small birds migrate at night and take their direction from the position of the setting sun. However, as well as seeing the sun go down, they also seem to see the plane of polarized light caused by it, which calibrates their compass. Travelling at night provides other benefits. Daytime predators are avoided and the danger of dehydration due to flying for long periods in warm, sunlit skies is reduced.
Furthermore, at night the air is generally cool and less turbulent and so conducive to sustained, stable flight. Continue Read F. Nevertheless, all journeys involve considerable risk, and part of the skill in arriving safely is setting off at the right time. This means accurate weather forecasting and utilizing favourable winds. Birds are adept at both, and, in laboratory tests, some have been shown to detect the minute difference in barometric pressure between the floor and ceiling of a room. Often birds react to weather changes before there is any visible sign of them. Lapwings, which feed on grassland, flee west from the Netherlands to the British Isles, France, and Spain at the onset of a cold snap. When the ground surface freezes, the birds could starve. Yet they return to Holland ahead of a thaw, their arrival linked to a pressure change presaging an improvement in the weather. In one instance a Welsh Manx shearwater carried to America and released was back in its burrow on Skokholm Island, off the Pembrokeshire coast, one day before a letter announcing its release!
Conversely, each autumn a small number of North American birds are blown across the Atlantic by fast-moving westerly tailwinds. Not only do they arrive safely in Europe, but, based on ringing evidence, some make it back to North America the following spring, after probably spending the winter with European migrants in sunny African climes. Write the correct letters in your answer sheet Which TWO of the following statements are true of bird migration?
Birds often fly further than they need to. Birds travelling in family groups are safe. Birds flying at night need less water. Birds have much sharper eyesight than humans. Only shorebirds are resistant to strong winds.

The potential to sniff out disease The fact diseases have a smell comes as no surprise - but finding someone or something that can detect them at an early stage could hold huge potential for medicine. Breath, bodily odours and urine are all amazingly revealing about general health. Even the humble cold can give off an odour, thanks to the thick bacteria-ridden mucus that ends up in the back of the throat.
The signs are not apparent to everyone - but some super-smellers are very sensitive to the odours. Joy Milne, for example, noticed her husband's smell had changed shortly before he was diagnosed with Parkinson's disease. Humans can detect nearly 10, different smells. Formed by chemicals in the air, they are absorbed by little hairs, made of extremely sensitive nerve fibres, hanging from the nose's olfactory receptors. And the human sense of smell is 10, times more sensitive than the sense of taste. But dogs, as the old joke might have had it, smell even better. Their ability to detect four times as many odours as humans makes them a potential early warning system for a range of diseases.
Research suggesting dogs' could sniff out cancers, for example, was first published about 10 years ago. And there have been many tales of dogs repeatedly sniffing an area of their owner's body, only for it to turn out to be hiding a tumour. What they are smelling are the "volatile molecules" given off by cells when they become cancerous. Others suggest they can detect very small tumours before clinical tests can. And yet more studies have produced mixed results. Does cancer smell? At Milton Keynes University Hospital, a small team has recently begun to collect human urine samples to test dogs' ability to detect the smell of prostate cancer. The patients had symptoms such as difficulty urinating or a change in flow, which could turn out to be prostate, bladder or liver cancer. Rowena Fletcher, head of research and development at the hospital, says the role of the dogs - which have been trained by Medical Detection Dogs - is to pick out samples that smell of cancer.
