REQUIRED VIDEO (Edmodo assignment)
1. What element is found in all organic compounds? 2. What is the benefit of carbon's small size? 3. Why does Hank describe carbon as a) "kind" AND b) a "trampy" element? 4. What is the Octet Rule? 5. What is the difference between an ionic and a covalent bond? 6. Making and breaking bonds is the " " |

REQUIRED VIDEO (Edmodo assignment)
1. Hydrogen and oxygen atoms of a water molecule are held together by what type of bond? 2. What type of bond holds water molecules to one another? 3. What is the difference between cohesion and adhesion? 4. Water is a "universal solvent". Describe the difference between hydrophilic and hydrophobic substances. 5. Why is it important to life that solid ice is less dense than liquid water? 6. How is it helpful to life that water has a high heat capacity? |

TOPIC SUPPORT
Watch this alternate video to gain a full understanding of the properties of water that make it essential for life. |
Sections 2.1 - 2.3
Key items: terminology (e.g. polar molecule, adhesion, cohesion, acid, base, buffer), bonding types (especially as they apply to water), blood buffers (e.g. bicarbonate) Here's a sample quiz to determine your current understanding. |

REQUIRED VIDEO (Edmodo assignment)
1. Carbohydrates are the source of all and the simplest sugar is called a . 2. What type of bond holds the individual sugar molecules together? 3. Name the molecules that we use to store energy. 4. What are the two components of a lipid molecule? 5. What are trans-fats and why are they bad for us? 6. Give some types of important groups of proteins. 7. What is a chain of amino acids called? 8. How many amino acids are we unable to make ourselves? TWO ADDITIONAL COMMENTS regarding the information in this video |

TOPIC SUPPORT
Bozeman also goes through the four major biological molecules of life. Some students may prefer the way he goes through the information. STUDYING HINT Topic support videos are a great way to review materials prior to the unit test! |
EXPERIMENT
Identifying Biological Molecules |
Use this worksheet to help you with molecule recognition.
Check the answer key before you cut them out for Step 2. |
Biological Molecule Diagrams
Key item: be able to visually identify molecules (word list provided) Use this QUIZLET set to help you study then take this QUIZLET test (you can adjust the settings) |

TOPIC SUPPORT
Use these two videos by Bozeman Science & Crash Course to gain a deeper understanding of ATP and its use in the body. NOTE: These go above and beyond (helpful for AP or post-secondary classes but beyond what we need) |
ACTIVITY
It's hard to visualize the complexity of molecules when all you've looked at are 2D representations on paper. Let's put together some 3D models and practice dehydration and hydrolysis. |
