Do Now: Update TOC: pg 65: Composites Compared to Polymers

Take out list from last nights homework: Look it over and discuss with the person next to you: What type of material was most of the

synthetic polymers you found made out of?

Look at Figure 5 on pg. 121: Compare and Contrast the Characteristics of each material: (Look at the MaterialsOn pg. 64 in Notebook: List the properties that make them different from each other

Plastics are Synthetic Polymers that can be molded or shaped, and are the most common synthetic polymer.

What is a characteristic that Natural and Synthetic Polymers have in common?

January 30, 2014Homework: In TB: Read pgs. 122-123 –(including the timeline -Tech & Design in

History) & pg. 124-125: Starting at Too Many Polymers: List the Benefits and the Problems with synthetic polymers on

pg. 66 in your notebook and write ideas to answer the question: How can these problems be solved?

Polymers & Composites (Take Notes on pg. 65)

Composites: Combines two or more substances into a new material with different properties:

Many Composite materials contain at least one polymer and can also be either synthetic or natural

One material is the binding material and one is the reinforcement

Examples: Concrete, Bricks, Wood, and Fiber Glass

Brick Fiber Glass Combines Mud and Straw

Combines thin glass shards & plastics

Brick is used to make buildings and other structures

Read Uses of Composites on pg. 124 in TBOn Page 65. in your Notebook:Write down two examples of

composites-- from what you just read. Add if they are Natural or Synthetic

Turn back to your original list of Composites from your search at home: Is there anything on your list you need to add or modify? Please do so…
