Monday 11/9/15 • AIM:Why is carbon an important element in your body? • DO NOW: What do you inhale? Exhale? WHY? • HOMEWORK: text read pages 51-53. Answer questions 1-3 on page 54
Monday 11/9/15 • AIM: How do atoms combine? • DO NOW: What are the 3 phases of matter and how are they different? • HW: Text Question 4 page 54
All matter is built from atoms • Atom is the basic unit of matter • Subatomic particles • Nucleus • Protons • Neutron • Orbitals • Electrons • Parts of an Atom Song - YouTube
Stable atoms • Properties of an atom • Due to the # of subatomic particles found in the nucleus • Ability of electrons to interact with other atoms • Want to be electrically neutral
What are the six most important elements to living organisms? CHNOPS
Carbon atom • Able to form 4 covalent bonds due to 4 electrons in outer shell • Combine to form large organic compounds
Carbon fun facts • Carbon is found in many different compounds. • It is in the food you eat, the clothes you wear, the cosmetics you use and the gasoline that fuels your car. • Carbon is the sixth most abundant element in the universe.
How are organic and inorganic compounds different? Organic compounds must Contain C and H Inorganic compounds Do not contain both NaCL CO2 H2O • CH3 • C6H12O6
Building molecules and compounds • Electrons of different atoms interact to form bonds • Loss or gain of electrons • Sharing of electrons
Thursday 11/12/15 • AIM: How do electrons interact? • DO NOW: 1- What are the 6 most important elements to humans? • 2- Explain the difference between organic and inorganic • HOMEWORK: UPCO page 85 read and answer all questions part A 1 and 2 Part B 1,2,3 and page 86 question 4
Friday 11/13/15 • AIM: How do water molecules interact? • DO NOW: 1- Why do atoms form bonds? • 2-Explain the difference between a covalent and ionic bond.
Why do atoms combine? How do atoms combine?
Atoms combine to build molecules and compounds • Electron interaction forms bonds • Loss or gain of electrons • Sharing of electrons
Atomic bonding • Electron interactions form bonds • Covalent bonds: electrons are shared between atoms • Electrons orbit both nuclei • 2 Hydrogen atoms share there electrons to form a bond
Ionic bonding • The loss or gain of an electron to form a bond
Ionic bonds • Forms ions or charged atoms • The atom that looses an electron is loosing a – charge so it becomes + • The atom that gains an electron is gaining a – charge so it becomes -
How does Carbon combine with other elements? • Carbon can share 4 electrons with 4 different atoms • Forms 4 covalent bonds
Why are we talking about this? BECAUSE ATOMS BUILD ALL LIVING THINGS AS WELL AS NONLIVING
Organization of human body • Atom • Molecule and compound • Biomolecule; carbohydrate, lipid, protien, nucleic acid • Organelle • Cell • Tissue • Organ • System • Organism
Assessment • In your own words, explain why carbon is an important element in your body.

One sheet per pair • 1- What is a monomer? • 2- What are the 4 categories of biomolecules? • EXTRA CREDIT: List the monomer that build each biomolecule
What are the four categories of organic compounds or biomolecules formed by carbon? • Carbohydrates • Lipids • Proteins • Nucleic acids
List at least 2 food sources that contain protein, 2 food sources that contain carbohydrate, 2 food sources that contain lipid.
Carbohydrate • Carbon, Hydrogen, Oxygen • Store and release energy • Starch and sugars • Glycogen and cellulose
Lipids • Carbon, hydrogen, oxygen • Fats, oils, waxes, steroids • Energy storage, protection, insulation and chemical messengers ( steroids)
Tuesday 11/17/15 • Aim: Why are biomolecules polymers? • Do Now: 1- Explain why lipids are organic compounds. • 2- Give the examples of lipids
Lipids are organic compounds because they are built from Carbon and Hydrogen • Fats, Oils, Waxes and steroids
Answer • All biomolecules are organic compounds • That means they are made up of Carbon and hydrogen • Organic compounds build living things so they are also called biomolecules

Protein • Carbon, Hydrogen, oxygen, nitrogen, sulfur • Structure for tissues and organs • Metabolism • Transport • Catalysts • Chemical Messengers (protein hormones)
How are enzymes related to proteins? • Enzymes are protein catalysts • Speed up chemical reactions
Nucleic Acid • Carbon, hydrogen, oxygen, nitrogen and phosphorous, sulfur • Store cellular information • DNA and RNA
(5 min) • Using the information you have received complete the table below
Biomolecules are polymers • Poly- many • Mer- unit • multiple units of smaller, repeating units • Build Large compounds • Why are carbohydrates polymers? • Because they are big molecules made from repeating subunits • Specifically monosaccharides
