CONTEXTUAL CHALLENGE For your NEA you will be given a choice of contextual challenges (CC), and from one of them, write your own brief to solve a problem the challenge presents. As this is a new skill, in year 10 we will work through some challenges together, so you can see how it is done. As we will be working on this as a class, many of the outcomes will be similar. In the real NEA, everyone’s project will be completely different.

Your NEA will also be based on the ITERATIVE DESIGN concept Your NEA will also be based on the ITERATIVE DESIGN concept. This means you will be constantly changing your ideas as feedback and information is gained. A good example of iterative design is the iPhone. Just look at all of the iterations over the years! Apple keeps updating it’s phone, based on feedback from consumers, new information and technology.

(Environmentally Friendly Storage for a Teenager) Based on the information you have so far, what material would you make your product from? (Environmentally Friendly Storage for a Teenager)

Environmentally Friendly Storage for a Teenager TASK Title: Contextual Challenge Mind Map Draw an oval in the centre of your page, with the CC written out in the centre: Environmentally Friendly Storage for a Teenager Add in the three branches on the board. What key words from the CC do you think will become the first branches of our mind map? Add them in.

Working in groups of 3, come up with as many words or topics as you can to expand on each branch. Write down ANYTHING you can think of, no idea is a wrong idea! You have 5 minutes Once the time is up take answers from the class and fill in the mind map on the whiteboard. Then discuss as a class what design briefs could be written from the gathered information. Explain for the real NEA all of these briefs could be used by different members of the class, but for this project they will be led.

POLYMERS Design Brief: To design and make a bag suitable for a 14-15 year old female to store everything they need for going out shopping on a Saturday afternoon. The bag must be made from plastics which can be recycled after the bag is no longer needed. The iterative design yellow cloud shows to ask the class what they would make their product from, now that they have seen the brief. A basic way of showing how pre-concieved ideas can change when more information is gained. Explain the brief has been given to them this time only – because it is the first time they’ve done it.

Thermoforming or Thermosetting? POLYMERS Thermoforming or Thermosetting? Think back to year 7, when you made your pen keepers, or had a go at vacuum forming. Discuss with the person next to you what the difference is between thermoforming and thermosetting plastics. You have one minute. Write what they come up with on the board.

POLYMERS Thermoforming or Thermosetting? Thermoforming plastics can be reheated and therefore reshaped. Thermosetting plastics cannot be reheated and reshaped due to a chemical reaction that occurs when they are first manufactured. POLYMERS Which do you think would be the best type to make our bags from?

POLYMERS Using textbook pages 91 – 93, fill in your worksheet.

Task: Look at the items in the bag, and identify the polymer. If you can spot a recycling symbol it will make identification a LOT easier! On the back of your properties worksheet, write the name of each object, followed by which type of polymer you think it is made from. Initials are fine instead of full names.

POLYMERS Which Polymer? Think back to our brief. What properties do you think the polymers we use must have? You now have a lot more information, so now what polymers would you make your bag from?

POLYMERS Homework Throughout the GCSE course you will be learning about lots of different types of materials. To keep track of them all, you will be creating a MATERIALS ENCYCLOPAEDIA as you go. There is a standard format sheet you can use, or you can design your own layout. You will be given samples of the materials by your teacher. You will need to buy a lever arch file to keep the pages in.

POLYMERS Homework Your first pages will be on the polymers you found out about in today’s lesson. By filling in the pages you will gain an in depth knowledge of each one.
