What to do

  • Highlight the main idea in each paragraph.
  • Discuss other fabrics that have been around for a long time.
  • What modern fabric do you think has changed the fashion world?
LO 3.2


In 1823, a Scot named Charles Macintosh invented raincoats. His waterproofing process was simple. He sandwiched a layer of rubber between two pieces of cotton. To keep the rubber soft, he mixed in a bit of turpentine. Then he handed his waterproof fabric over to a tailor, who turned it into raincoats called Macintoshes, or macs for short.

Do you know of any other articles of clothing named after the inventor? See what you can find out and report back to the class.

Would you ever have thought that you could become a famous inventor because you invented some new FOOD?

Some inventors have become famous because of the food they invented. Back in 1762, a gambler named John Montagu got too involved in card games to stop for meals. When he got hungry, he just slapped some meat between two pieces of bread and ate as he played. His invention was named after him. (John Montagu’s formal title was the fourth Earl of Sandwich.)

What to do

  • Demonstrate the making of your favourite sandwich in class. Be inventive and make it with a difference! Then have a class picnic and swop sandwiches. Eat and enjoy!
  • Read about a mouth-watering sandwich made by Petie Burkis in The Midnight Fox written by Betsy Byars.
  • Design a class recipe book of favourite lunch snacks (the tasty goodies your mom invents to tantalize your taste buds or what you wish she would include in your lunchbox).

LO 2
SPEAKINGThe learner will be able to communicate confidently and effectively in spoken language in a wide range of situations.
We know this when the learner:
2.2 communicates ideas, facts and opinions clearly and with some accuracy and coherence, using a limited range of factual oral text types (e.g. discussions, short arguments);
2.4 demonstrates basic interaction skills by participating actively in group discussions, conversations, interviews and debates.
2.4.2 takes on different roles;
2.4.3 acknowledges other opinions;
2.4.6 bridges gaps by asking questions, giving choices, keeping responses open-ended and showing genuine interest.
LO 3
READING AND VIEWINGThe learner will be able to read and view for information and enjoyment, and respond critically to the aesthetic, cultural and emotional values in texts.
We know this when the learner:
3.1 reads spontaneously and often for pleasure and information across the range of text tyes studied, describes personal response and discusses the kinds of texts enjoyed;
3.2 reads aloud and silently for a variety of purposes using appropriate reading strategies (e.g. skimming and scanning, presictions, contextual clues, inferences);
3.4 shows understanding of information texts:
LO 4
WRITINGThe learner will be able to write different kinds of factual and imaginative texts for a wide range of purposes.
We know this when the learner:
4.1 writes a selected range of imaginative texts:
4.1.1 to express imagination, ideas and feelings about self and others;
4.1.2 to explore the creative and playful use of language by means of narrative and descriptive compositions, diaries, friendly letters, dialogues, poems, cartoons, limericks and songs;
4.4 uses the writing process with assistance and collaboratively to generate texts:
4.4.4 organises ideas coherently in simple, logical order to produce first drafts.
LO 5
5.1 uses language to think and reason:
5.1.1 infers and deduces meaning and explains the intentions of the author by interpreting written, visual and aural texts across the curriculum;
5.1.4 expresses and develops a clear personal viewpoint;
5.3 processes information:
5.3.1 records information in an accessible format (e.g. lists, mind maps, notes, summaries);
5.3.2 organises information appropriately (e.g. by time, importance);
5.3.3 changes information from one format (or language if necessary) into another (e.g. mind map into paragraph, list into summary);
LO 6
LANGUAGE STRUCTURE AND USEThe learner will know and be able to use the sounds, words and grammar of the language to create and interpret texts.
We know this when the learner:
6.1 works with words:
6.1.2 creates personal spelling list and dictionary of words across the curriculum;
6.2 works with sentences:
6.2.1 identifies and uses nouns, verbs, modals, adjectives, pronouns, prepositions, conjunctions, and articles.
6.4 develops awareness and use of style:
6.4.3 uses idioms and idiomatic expressions of the language appropriately.

what are the products of Nano chemistry?
Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
yes that's correct
I think
Nasa has use it in the 60's, copper as water purification in the moon travel.
