Organic and Inorganic molecules Ms. Blalock, Ms. Hartsell, and Mr. Luckman
Do Now � What are some differences AND similarities between water and sugar?
Today’s Agenda � At the end of this lesson, we will be able to: ◦Identify organic and inorganic molecules ◦Explain the difference between organic and inorganic molecules ◦Identify the four essential organic compounds that make up life � Aim: How can you identify the organic and inorganic molecules of life? How do I distinguish between these two molecules? � Agenda: ◦ 1. Do Now ◦ 2. Learning the terminology ◦ 3. Introduction: Organic and Inorganic ◦ 4. Activity 4: Organic vs. Inorganic ◦ 5. Organic Compounds ◦ 6. Activity 6: Poem and Song ◦ 7. Activity 7: What did I really eat last night? ◦ 8. Exit Ticket
Terminology Atom Element Definition: Basic building blocks of all Definition: A substance that is made matter that make up everyday objects up of only one type of atom - Smallest amount of an element - Examples include: oxygen and hydrogen Compound Molecule Definition: A molecule that contains two Definition: Two or more atoms that are or more elements joined together -Examples include: glucose (C 2 H 12 O 6), - Examples include: H 2, O 2, H 2 O Carbon dioxide (CO 2)
Real Life Example: Ice Cream Analogy Atom Compound Molecule Elements
Most common elements in living organisms � Carbon � Hydrogen � Oxygen � Nitrogen � CHON
Organic versus Inorganic Organic Compounds Make-up -Contain both carbon and hydrogen atoms formed together by bonds - Come from living organisms Example: -Sugars such as glucose C 6 H 12 O 6 Inorganic Compounds Make-up -DO NOT contain these carbonhydrogen bonds Example: -Water H 2 O
Take it back to the Do Now Discuss with your partner: Using your understanding of organic and inorganic, how do sugar and water differ? How are they similar?
Activity 1: Identifying organic and inorganic � Directions: Identify each molecule/compound as organic or inorganic. � When finished, talk with your group about the following question: � Can you infer from their formulas which seem more complex, inorganic or organic compounds?
Activity 1: Identifying organic and inorganic Answers to Activity 1: Sand Si. O 2 Inorganic Sucrose C 12 H 22 O 11 Organic Steel Fe Inorganic Cellulose C 6 H 10 O 5 Organic Hydrogen Peroxide H 2 O 2 Inorganic
Four classes of organic compounds Carbohydrates Make-up - Carbon - Hydrogen - Oxygen Proteins Make-up - Carbon - Hydrogen - Oxygen - Nitrogen Lipids Make-up - Carbon - Hydrogen - Oxygen Nucleic Acids Make-up - Carbon - Hydrogen - Oxygen - Nitrogen Role in living organisms -Cells use to get and store energy Role in living organisms -Act as catalyst -Structural part of organisms Role in living organisms -Store long term energy Role in living organisms -stores genetic energy (DNA) -makes proteins (RNA) Examples: -Fats -Oils -Waxes Examples: -DNA -RNA Examples: -Sugars (glucose) -Enzymes -Starches -Hair -Nails
Building blocks Yesterday, we discussed how the basic building blocks of all living things are cells. The four classes of organic compounds also have basic building blocks. ALL living things Carbohydrates Proteins Lipids Nucleic Acids cells monosaccharide s (simple sugars) amino acids fatty acids nucleotides

Activity 2 (15 minutes) � Directions: Using one of the options below, identify and explain each of the four classes of organic compounds. ◦Option 1: Write a poem identifying and explaining the four classes of organic compounds ◦Option 2: Write a song identifying and explaining the four classes of organic compounds � In your poem or song, you must mention the following for each organic compound: ◦Make-up of the compound ◦ONE role of the compound ◦ONE example of the compound � Time: ◦ 10 minutes to create song or poem ◦ 5 minutes for whole class sharing
Activity 3 (5 minutes) Directions: 1. Make a list of the foods you ate last night for dinner or yesterday for lunch. 2. Categorize the foods into the following categories: - Carbohydrates - Proteins - Lipids - Nucleic Acids 3. Of those that contain proteins and nucleic acids, what are the building blocks of these foods? 4. Explain the relationship between a balanced, healthy diet and the consumption of these organic compounds.
