ENGLISH ROMEO & JULIET
Context for Romeo and Juliet:
Shakespeare li ed the ideas for ‘Romeo and Juliet’ from the poet Arthur Brooks, who first brought the story Romeus and Juliet to an English speaking audience.
The play is set in Italy. This reflects a more exo c and distant country with ro-man c ideas about love and violence.
Shakespeare’s tragedies are based on the tragic plays of ancient Athens.
Aristotle proposed that a tragedy should be based around one single loca on and happen during the course of one day. Shakespeare’s plays are a more re-laxed version of this.
Romeo and Juliet is a tragedy and follows many of the conven ons of a tragedy.
Conven ons of a tragedy:
Protagonist — has a fatal flaw in their personality.
Hamar a — a fatal flaw leading to the downfall of a tragic hero or heroine.
Catharsis — audience feels fear and pity towards the characters/events in the play.
Conflict — both external and internal conflict
Tragic waste — “tragic waste of goodness”
Extreme wealth
External pressures
Sympathy for the hero
Comic relief — one or more humorous characters
Hubris — excessive pride or self-confidence
Peripeteia — a sudden reversal of fortune and change
Act Summary
Act 1 Fight between Capulet Servants and Montague Servants. Tybalt and Benvolio get caught up in the figh ng. The Prince stops the figh ng and disciplines the two families.
Lord Capulet and Paris discuss Juliet and their desire for Paris to marry Juliet. Lord Cap-ulet hosts a masque ball. Mercu o and Romeo (with friends) turn up at the ball uninvit-ed. Tybalt spots Romeo. Lord Capulet warns Tybalt not to start a fight in his home.
Romeo and Juliet spot each other and fall in love.
Act 2 A er the party, Romeo stays behind and climbs the wall to Juliet’s room.
The two talk about their love for each other. They agree to marry the next day.
Friar Lawrence agrees to marry the two in secret. He believes this will end the feud between the two families and make sure that Romeo forgets about Rosaline.
The Act ends with the two of them being married.
Act 3 Benvolio and Mercu o (both Montagues) meet Tybalt (Capulet). He is looking for Ro-meo. Romeo arrives (a er his wedding to Juliet) and Tybalt tries to provoke Romeo into figh ng. Tybalt kills Mercu o. Romeo kills Tybalt. The Prince banishes Romeo.
Romeo goes to the Capulet house, in secret, to consummate his marriage to Juliet. He leaves early the next day. Juliet is told that she is to marry Paris. Juliet defies her moth-er and father.
Act 4 Paris is making arrangements for their wedding with Friar Lawrence. Juliet speaks to Friar Lawrence and says she will kill herself rather than marry Paris. Juliet returns home with the poison that will make her appear dead. She tells her father that she will marry Paris (knowing that the Friar has a plan to prevent this from happening). Juliet sleeps alone and takes the po on.
Act 5 Juliet is found ‘dead’. The news travels to Romeo. He hasn’t received news from the Friar and believes it to be true. Romeo goes to Juliet’s grave where Paris is mourning her. Romeo kills Paris and then himself. Juliet wakes up and kills herself.

English Technical Accuracy
Hear: Sound Here: place/posi on
They’re: They are Their: possession to show someone owns something
There: place and posi on
You’re: You are Your: possession to show someone owns something
Too: also, in excess To: before a verb Two: number
Homophones: words the sound the same but are spelt differently
Where: place Wear: clothes
Sea: ocean See: sight
Speech Punctua on:
Always use speech marks “…” around speech (when a character says something)
Always include any punctua on inside the speech marks. For example if a char-acter asks a ques on, put the ques on mark inside the speech marks.
Always start a new line when someone new speaks.
Vary your use of verbs/adverbs to describe how the speaker says something (asked, replied, angrily, smirked, whispered, laughed…)
Start each line of speech with a capital le er.
Rules for spelling: Plurals
1. Regular nouns, add S: Car / cars, apple / apples
2. Irregular nouns – learn them: man/men, woman,/women, person/people, mouse/mice, tooth/teeth, foot/feet, child/children
3. Words ending in S, CH, SH, X or Z, add ES: bus/buses, match/matches
4. Words ending in F or FE, remove the F / FE and add VES: leaf/leaves, wolf/wolves
5. Words ending in a consonant + Y – remove the Y and add ies: city/ci es, party/par es
6. There are some words which do not change when in plural form: sheep, deer, species, series
Rules for using paragraphs/sentence starters:
You must always use paragraphs in your wri ng.
You must use paragraphs to show a change in: me, topic, place or person.
You must indicate a change in paragraph by star ng a new line/inden ng the wri ng away from the margin/edge of your page.
Avoid star ng sentences with the same words. Rather than using ‘then’, try ‘next’, ‘a er some me…’, ‘following on…’ . Avoid using ‘suddenly’ too o en.
Use a range of adverbs to start sentences.
Rules for using apostrophes:
An apostrophe should be used to show something belongs to someone.
“Isaac’s basketball was flat.”
An apostrophe should be used to replace a le er: don’t (do not)
An apostrophe should not be used when using plurals: The gers were asleep.

Happisburgh Case Study
Loca on: Happisburgh is located on Norfolk's North Sea coast. Over 250m of land was lost between 1600 and 1850. Coastal defences (groynes and revetments) have slowed down the rate of retreat, however, large sec ons are now in disrepair.
Reasons for Erosion: The cliffs are made of sand and clay, which erodes easily. The strong waves from the North Sea have a rela vely long fetch. Weathering from heavy rainfall has also soaked into the soil and weakened the cliffs.
Impacts: 10m of farmland lost each year. 26 homes lost in 15 years, with 600 more under threat. Residents can’t sell their homes and are struggling to get compensa on. Local tourism is also affected as 1,400 caravans, 6 hotels, 7 golf

Physical Educa on The Heart The right‐hand side of the heart is responsible for pumping deoxygenated blood to the lungs.
The le ‐hand side pumps oxygenated blood around the body.
Each side of the heart consists of an atrium and a ventricle which are two connected chambers.
The atria (plural of atrium) are where the blood collects when it enters the heart. The ventricles pump the blood out of the heart to the lungs or around the body.
The septum separates the right-hand and le -hand side of the heart.
The tricuspid valve is located between the right atrium and right ventricle and opens due to a build-up of pressure in the right atrium.
The bicuspid valve is located between the le atrium and le ventricle and likewise opens due to a build-up of pressure, this me in the le atrium.
The semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves the le ventricle and another where the pulmonary artery leaves the right ventricle.
The aorta is the largest artery in the body. It carries oxygenated blood away from the le ventricle to the body.
The vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart.
The pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs.
The pulmonary vein returns oxygenated blood from the lungs to the heart.
The pulmonary artery takes de‐oxygenated blood back to the lungs from the heart.
Blood
Artery Vein Capillary Function Carries blood away from the
heart (usually oxygenated blood, except for the pulmo-nary artery).
Carry’s blood towards the heart (usually deoxygenated blood, except for the pulmonary vein).
Allows diffusion of gases and nutrients from blood into the body cells.
Wall Thick, muscular. Thinner. Very thin, one cell thick.
Lumen Small. Large. Very small, only allows blood to pass through one cell at a time.
Other features Thick muscular walls to with-stand blood flowing at high pressure as it leaves the heart; the largest artery is the aorta.
Contain valves to prevent back flow of blood.
Walls are made of semi-permeable membrane to allow transport of gases and nutri-ents into and out of the blood.
Key Syntax:
Handling Data Types:
Convert to integer
Convert to float
Convert to string
Convert to Boolean
User input in python is always a string by de-fault.
Variable Name Conventions:
Should not be overly long but should be easy to identify purpose. Must start with a letter. Must not contain any symbols or spaces. In-stead of a space, use an underscore or camelCase, e.g.: user name user_name userName
Key Skills Understanding Python Code:
A: Stores user inputted text to a variable called name.
B: Stores an integer value 14 to a variable called age.
C: Creates a list which contains 2 string values. Stores to users.
D: Calculates the length (how many items are in) of users.
E: Stores the Boolean value False to variable valid.
F: Use of white space to make code clearer.
G: Creates a loop that will iterate for every element in us-ers.
H: Use of selection to determine if the entered value match with any values from the list. users[i] looks up the current value from the list based on the given index.
I: If the name is in the list users, valid is changed to True.
J: Selection based on whether valid was changed to True.
Annotation: Commenting on your code to explain what parts do. Assignment: Storing a value (numerical or otherwise) to a variable. Data Structure: A way of storing multiple bits of information at once. Index: A position reference in a data structure. Iteration: Repeating sections of codes using loops, usually with changing values each time. List: Also known as an array. A data structure. Module: A collection of linked functions. External modules can be imported in to your code.
Selection: Using code to choose what happens in a pro-gram. Also called a conditional. User Input: Allowing the person using the code to provide data.
Variable: A value that can change. Used to store infor-mation for use in a code.
= used for assignment == used for comparison
Python functions (such as print or len) must have brackets after them, which may contain information. E.g. print(“Hello”) or exit()
Keywords in lower-case only e.g. if, while
# used to start a comment
: must be used at the end of selection and iteration

They can be melted and re‐formed.
They have plas c memory.
COMPOSITES Composites are when materials are combined to achieve specific advantages.
Examples of composites are Kevlar, GRP (Glass reinforces plas c, Graphite and Carbon Fibre.
Uses for composites= Bike frames motor racing car bodies, tennis rackets.
High Density Polythene (HDPE) is tough and can be blow moulded (bo les for bleach and shampoo), injec on moulded (toys and buckets), extruded (piping)
Low Density Polythene (LDPE) is made into thin film (carrier bags, wiring insula on and squeezy bo les)
ABS Acrylonitrile Butadiene Styrene is strong, tough, scratch resistant and resists heat and chemicals. It is injec on moulded (Lego bricks, Ke les, vacuum cleaners, telephones)
PVC Polyvinyl Chloride can be plas cised by different amounts to make a wide range of products (window frames, gu ers, disposable pens, credit cards). It is strong, s ff and weather resistant.
PP Polypropylene is versa le and flexible without breaking and can withstand variable temperatures (yoghurt pots, crisp packets, garden furniture and car bumpers).
