To investigate the hill reaction
Name: Kern Pemberton Date: 7th November, 2008 Lab#: 5 Aim: To investigate the hill reaction Theory: Photosynthesis is a process carried out in plants, in the photosynthetic organ which is the leaf. CO2 + H2O --> (CH2O)n + O2 A plant takes in CO2 and H2O and absorbs sunlight in order for photosynthesis to take place. These reactants then travel to the chloroplasts in the palisade cells of the leaf, where the actual process takes place. In photosynthesis there are two reactions; the light dependant reaction and the light independent reaction. The light dependant reaction takes place in thylakoids of the grana of the chloroplasts whereas the light independat takes place in the stroma. The thylakoids of the chloroplasts contain pigments which can be divided into accessory and primary pigments. These pigments form light harvesting clusters which can then be divided into different photosystems, those being photosystem I and photosystem ll. In photosystem I, the accessory pigments trap energy from the sunlight and funnel it to the primary pigment or chlorophyll a. This then becomes excited and releases an electron which is accepted by an electron acceptor. The electron then moves through a series of electron carriers arranged in order of their redox potentials. Meanwhile, the photosystem is said to be unstable as a result of chlorophyll a losing an electron. The electron
Hill Reaction Lab
Wednesday 18th of Mach 2009 IB Photosynthesis Experiment Aim of the Experiment: To investigate the effect of light intensity on the rate of photosynthesis. A relation is sought for that would, if existent, allow estimation for untested values of light intensity. Research Question: How does controlled light intensity affect the rate of increase in the excess of oxygen created by the elodea plant undergoing photosynthesis? Hypothesis: Many plants use the process of synthesis to convert light energy into chemical energy (carbohydrates). The waste product, useful for other life forms is oxygen, a product of photolysis. Carbon dioxide, water and chlorophyll and light are essential for this reaction. The scarcity of any of these affects the rate of reaction. By controlling light intensity one should limit the rate of reaction of photosynthesis and hence the excess oxygen produced should have a varying rate linked to the light intensity. We therefore need to control at least one of the other controlling factors of photosynthesis and in this lab it will be temperature. For this experiment the variables are the following: Independent variable: light intensity, changed by varying the light's distance to the elodea complex. This is the photosynthesis factor which behaviour is investigated. Dependant variable: the rate of photosynthesis, id est the speed of the bubble which is
Beacon hill coursework
Beacon Hill Beacon Hill is a mysterious feature that has baffled experts for many years and still no one has found a true answer. In this piece of coursework I am going to investigate why Beacon Hill was built. Beacon Hill is a man made mound which is situated in Wollaston in Northamptonshire. There are 4 different theories for what Beacon Hill could be these are; a Bronze Age barrow, a Roman Specula, a 12th century motte and bailey castle and a signalling station of the time of the Spanish Armada. The Bronze Age barrow is a man made mound of stone, wood or earth piled over the remains of the dead. Roman Specula were fortresses used to protect themselves and their allies. A 12th century motte and bailey castle was a simple castle made out of earth and wood. The signalling station was the way that England could warn the rest of the country that the Spanish Armada was coming. In this piece of coursework I will analyse a series of sources relating to Beacon Hill and what it could be. After analysing the evidence I will reach a conclusion to what I think Beacon Hill is based on the evidence. Bronze Age barrows are man made mounds of stone, wood, or earth piled up over the remains of the dead, especially important people. Often possessions would also be buried. Bronze Age barrows were built between 2000BC and 1000BC. There are 3 sources that support the theory of Beacon Hill
Marble Hill House.
. Study Source A What can you learn from source A about Henrietta Howard? Source A is a portrait of Henrietta Howard, painted by Charles Jervas for Alexander Pope. This suggests that the portrait was of reasonably high value if a great poet like Pope had the portrait painted specially for him. This also infers that Henrietta must have been of a high status if she had gained her place as one of the fascinations of the poet/satirist and the subject of some of his poems. The fact that the portrait was painted by Charles Jervas also suggests that Henrietta Howard must have been a popular lady of a high status and great importance considering that the artist was one of the most prolific and sought after portrait painters of his day. Kings, Queens, ladies and gentlemen of high society and many famous poets and writers sat for him, and he succeeded Sir Godfrey Kneller as the portrait painter to George I and then George II. This highlights his importance and is also a sign of the value of the painting which was probably quite high as it was painted by an important artist for an important poet, of an important and fashionable Lady. Her pose is an important aspect of the portrait because it is not one which a woman would have been expected to hold. It was normally reserved for men of letters, but she is neither a man nor a writer, so we can acknowledge from this pose that she had
the notting hill carnival
Module: Arts and Events : Theory & Practice Code: LT2020N "The Notting Hill Carnival" Student : David Moradeyo ID: 04013923 Seminar Tutor: Maggie Gold The Notting Hill Carnival The aim of this case study is to use theoretical perspectives to analyse an arts or events activity that clearly integrates diverse concepts of the arts or events activities such as tradition, identity , authenticity ,invention ,boosterism and imperialism. The event selected here has the features of both an art and event activity, the Notting hill carnival can be described as an event and an art activity in the sense that it is an organised event that celebrates the arts of music , dance , costumes and heritage. The Notting hill carnival is the second largest arts festival in Europe and it is held in central London, with Ladbroke Grove being the centre of the carnival, dating back to 1966 the Notting hill carnival has become a huge multi cultural arts festival attracting over 2milllion people and also becoming a major tourist attraction in London. The Notting hill carnival originated from the arrival of Trinidadians in great Britain, they were inspired by the carnivals organised in Trinidad which motivated them to create something similar to what they experienced back home resulting to a small number of people carrying steel drums and costume parades in the streets of Ladbroke grove and
Geography Coursework - Merry Hill
Course Work Aims: The aim of my course work is to investigate if three shopping centres in the west midlands can be placed into shopping hierarchies. Hypothesis: My hypothesis is that * Merry hill will have a bigger sphere of influence than Kidderminster and Dudley * Merry hill will have a better environment than Kidderminster and Dudley * Merry hill will have more comparison shops than Kidderminster and Dudley Justification of hypothesis: I predict that the settlements will fit in the following hierarchy. First Prediction: People will travel farther - I predict that Merry Hill will be at the top of the hierarchy because it is more accessible (roads, bus routes, railway links and motorway), it contains better facilities (shops, restaurants, car parks), it will also have high order goods. As Merry Hill contains all of the following, it will be at the top of the hierarchy. I predict that Dudley will be at the bottom of the hierarchy because it is less accessible than Merry Hill and Kidderminster, it has low quality facilities compared to Merry Hill and Kidderminster and it mainly supplies low order goods. To prove this I will collect car registrations and shopper surveys. Second prediction: Environment Quality - I predict that Merry Hill will
Notting Hill (Richard Curts)
Sam Errington 11R Notting Hill Essay Notting Hill is a typical example of a Richard Curtis film. This is due to many factors, including the basic storyline, the roles of the characters, the actors/actresses, and the scenery. The basic storyline is a typical rom-com storyline; it has two people who fall in love, break up, and get back together again. William Thacker (Hugh Grant) and Anna Scott (Julia Roberts) meet up in a bookshop, but nothing happens between them. They then meet in the street after he accidentally spills orange juice down her top. He then takes her back to his place so she can change, and that's where the love begins. They then break up further on in the film, and when she asks to get back together he turns her down because he thought it was the right thing to do, but then he talks with his mates about and he realises that he made a mistake. They all help him get to the hotel where she is staying, but she checked out and went to a press conference, and the have a car chase through the busy streets of London in a Volvo, and one of his friends gets out of the car to stop traffic at a busy junction, where in real life he would have just been run over. He eventually catches up with her and speaks to her, and they then decide to get back together, and it has a conventional happy ending with a wedding. It begins with William Thacker walking down the high street
Notting Hill Film Review
Media - Notting Hill Review Notting Hill is a film directed by Roger Michell and PolyGram film studios and distributed by Universal Pictures. The film stars Hugh Grant, Julia Roberts, Hugh Bonneville, Emma Chambers, James Dreyfus, Rhys Ifans, Tim McInnerny and Gina McKee. The film was made in 1999 and runs for about 124 minutes. Notting Hill is one of those films you see in a "must-see" chart. I had no idea what it was about; therefore I didn't know what to expect. It is a romantic comedy and its tagline is 'Can the most famous film star in the world fall for just an ordinary guy?' The movie shows that love can conquer even the largest divides in social standards. It also shows the effect on celebrities when their privacy is compromised by tabloid journalism. Notting Hill is the story of a globally famous actress who attempts to have a normal relationship with a normal man. William Thacker (Hugh Grant) an average Portobello bookshop owner, who is stuck in the daily grind of his life, opens the movie by ______ on the way to the travel bookshop that he owns. Whilst at work, the Hollywood actress Anna Scott (Julia Roberts) walks in to his shop. After buying a book and leaving, Thacker assumes she has walked out of his life for good, leaving him to continue his repetitious, normal routine. In an unexpected twist in events, Anna Scott ends up in his small home across the
Chips with Everything - Corporal Hill
Chips with Everything James Birchall 11G Corporal Hill Hill is a professional airman and sometimes represents a typical aggressive N.C.O. (Non-commissioned Officer). A typical N.C.O is aggressive; this is to gain respect from his recruits from the start. At the start of the play, he enrols in his character by shouting and making himself known as a person who expects discipline, "when I ask a question, I expect an answer..., is that understood!" After he makes this statement he gets a positive answer, "Yes corporal!" he has now got the discipline from the group. Yet he is a strangely contradictory character as one minute he is telling the new conscripts, "I never smile and I never joke," the next he is remembering the last bunch of recruits fondly, "We 'ad bags o' fun o' it." He then goes on to say " I will tear and mercilessly scratch the scorching daylights out of anyone who smarts the alec with me - and we've got some ere". The words here proves what kind of a character he is, he demands respect and from the words used here it seems he is a powerful character. The language is gruesome, intimidating and frightening; this is all to gain the respect from the recruits. Going back to this contradictory image, he also shows this in his attitude towards the 'softer', more vulnerable targets in his hut. He seems to relish telling them, "some of you shall end up crying," This
On the Black Hill.
On the Black Hill i Long Essay By Carina Uehr "Our life is like a bubble. We are born. We float upwards. We are carried hither and thither by the breezes. We glitter in the sunshine. Then, all of a sudden, the bubble bursts and we fall to the earth as specks of moisture. We are these dahlias, cut down by the first frosts of autumn..." (p. 246) O n the Black Hill follows the lives of the Jones twins, from when they are first born until their bond is broken with Lewis' death. The novel explores their experiences and relationships with other characters, and how they are intertwined with these people and the landscape around them. Bruce Chatwin weaves a large tapestry of time, in which each pattern stands out but is still part of the one whole. Themes, settings, relationships and conflicts all contribute to this tapestry, the ultimate meaning of the novel. Two significant scenes that stand out in the pattern of meaning are the first chapter, and the Rhulen Fair. They explore the themes and conflicts of the novel, and Benjamin and Lewis' relationship with each other and their mother, the most important character in the novel after the twins. T he first chapter (p. 9 - 14 ) is not by strict definition a scene, but it carries a vital importance to the meaning of the novel. Like any good introduction should, it lays out the bare bones of the following
