1 1/13 & 1/ th Grade Agenda Learning Objective: Learn about Polymers Last Day to turn in Late work Collect HW: Reading & Notetaking: p.146 – 147 Science Fair Background Presentations Textbook Reading p HW: Reading & Notetaking p.148 – 150 Reminder Procedure, Data Table, Graph & Procedure due 2/5 & 2/6 (15 Points)

2 Daily Reflection Prompt: Write 3 questions about polymers.

3 Last day to turn in late work

4 What is a Isomer? Compounds that have the same chemical formula but different structural formulas are called isomers Butanes and isobutane have different melting points and boiling points

5 Double Bond Single bond hydrocarbons end in “-ane” like Propane
Double Bond hydrocarbons end in “-ene” or “-yne” like Ethene.

6 Hydroxyl Group Hydroxyl group is a “OH” compound used for substitute for hydrogen atom in hydrocarbons Alcohol is a substituted hydrocarbon that contains one or more hydroxyl group Ethanol is produced natually by yeast when they consure sugar stored in corn, wheat and barley Methanol (poisonous) Ethanol

7 Polymers vs. Monomers Polymer: A very large molecule (millions of atoms) made of a chain of many smaller molecules. Monomer: Smaller molecule – the links that make up the chain

8 What are some natural Polymers?

9 What are some examples of Natural Polymers?
Wool Cotton Silk DNA & RNA Protein Carbohydrates Starch

10 What are some man made Polymers?

11 What do plastics and cells in your body have in common?
They are both made of carbon compounds

12 What are the four types of polymers found in all living things?
Carbohydrates Lipids Proteins Nucleic Acids ???????? ???????? ???????? ????????

13 Carbons can form four covalent bonds
They can also bond to each other in changes and ring shaped groups

14 What are composites Composites combine two or more substances as a new material with different properties

15 What is the simplest carbohydrates?
Sugar One of the most important sugars in your body is glucose C6H12O6 Glucose is also known as “blood sugar” because it is circulated through out your body

16 Starch is a form of complex carbohydrate
Starch is a form of complex carbohydrate. Which food contains lots of starch? Rice Potatoes Bread Cereal Pasta Wheat
