  1. January 29th, 2014 Happy Wednesday!!! 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?

  2. Plastics are Synthetic Polymers that can be molded or shaped, and are the most common synthetic polymer. Look at Figure 5 on pg. 121: Compare and Contrast the Characteristics of each material: (Look at the Materials On pg. 64 in Notebook: List the properties that make them different from each other

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

  5. January 30, 2014 • Homework: • 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? • Do Now: • Write Down your homework, • Update TOC: Pg. 66 Benefits & Problems: Synthetic Polymers H.W.: • OpenNotebook to page 62: Open Textbook to page 122

  6. Pg. 62 Polymer and Composites HW Sheet Answers • 6) Natural • 7) Synthetic • 8) Synthetic • 9) Natural • 10) C • 11) D • 12) A • 13) E • 14) B 5) Composites are useful because…?

  7. 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

  8. Brick Fiber Glass Combines Mud and Straw Combines thin glass shards & plastics

  9. Brick is used to make buildings and other structures

  10. Read Uses of Composites on pg. 124 in TB • On 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… 
