Powerpoint containing materials and renewable, non-renewable resources.
1. IDENTIFICATION OF MATERIAL CONSTRAINTS Design and Technology
2. RECAP: SCENARIO ONE A student has created a neutral aesthetic toy for his target audience of 4-6 year olds. When the toy was given to the age group, only 1/20 children played with the toy. Why is this?
3. WHAT ARE MATERIALS? Materials are a matter from which objects can be created. As young designers, you will need to consider the context and impact which these materials will have on your product.
4. SURPRISE QUESTION As the world is progressing, we are using an increased number of environmentally friendly materials. What is the word for this?
5. WHAT TO CONSIDER When picking a material to create your product from, you need to take into account their working properties and characteristics. What are working properties and characteristics? https://www.youtube.com/watch?v=340MmuY_osY
6. WOOD: Wood is a hard material which is often found in the barks of trees. Working properties Charecteristics Can be compressed Rigid Shock absorbent Tough Can be stretched Has dark and light colours Shrinkage Density
7. GLASS Glass is a fragile material which is made from sand Working properties Charecteristics Heat resistance Transparent Shatterproof glass Fragile Malleable in liquid state Brittle Great for light transmission Weather resistance
8. PLASTIC Plastic is a material found in our daily lives. They are made from a certain polymer. Working properties Charecteristics Can be malleable when heated Multitude of colours Easily moulded Lightweight Ductile Strong Corrosion resistant Water resistant
9. FABRIC Fabric is a material which is made from many plastics and polymers binding together. This also helps make the materials stretchy. Working properties Charecteristics Stretchy Different textures Durable Variable thickness High Resistance Multitude of colours Shape can be manipulated Textures
10. METALS Metals are materials which come in a variety of differednt forms and are able to conduct electricity. Working properties Charecteristics Malleable Good conductors Durable Can be made thin or thick Tensile strength Come in a few colours Compressive Cant be painted
11. SMART MATERIALS New emerging technology has generated smart materials. A smart material is when the physical properties of a material can be altered. e.g. mood rings, colour changing mugs, glow in the dark sticks
12. RENEWABLE AND NON RENEWABLE Renewable resources are those which have an endless supply as they can be regenerated Some examples can be bio fuel, wood, cotton and many more From this definition can you tell me what non renewable materials are?
13. WHAT TO CONSIDER WHEN PICKING A MATERIAL When picking a material, it is important to consider the function. E.g. If your product is a toy which may be used indoors and outdoors, will leaving in the rain cause it to rust, break down? If you are making a piece of furniture, will the material used be able to withstand people sitting on it or utilising it?
14. Finish off the double page spread about the sustainabvle materials from last lesson. Make x4 single page spreads about each material which we learnt about today, include the working properties, charecteristics, if they are renewable or non renewable and their sustainability., how you will use this material in your design. Include pictures and add colour.
