Bio 9C: Thursday, 11.18.10Title: Quiz #4: Carbon Compounds and Enzymes
Homework: Complete sections of the lab report that you have not yet
completed (Background Info, Purpose, Hypothesis, Procedure, Creating Data Table, Analysis and conclusion)
Food Poster Revisions Due Tomorrow! McMush Revisions Due Monday!
Do Now: Clear your desks and get ready for the quiz!
Objectives for Class:Demonstrate understanding of:• Describe the structures and functions of carbs, proteins, and lipids.• Identify the sources of carbs, proteins, and lipids in foods.• Explain the difference between reactants and products in a chemical reaction• Explain how an enzyme’s structure fits it function• Explain why enzymes are important for chemical reactions
Quiz #4: Carbon Compounds & Enzymes
No talking If you have a question or need
something from your bag, please raise your hand and ask permission
When done, please put your quiz face down on the kidney table in the appropriate pile (version A or version B).
Get a computer and work on the lab write-up.
We have to go take pictures at 1:30Objectives for Class:• Describe the structures and functions of carbs, proteins, and lipids.• Identify the sources of carbs, proteins, and lipids in foods.• Explain the difference between reactants and products in a chemical reaction• Explain how an enzyme’s structure fits it function• Explain why enzymes are important for chemical reactions
Homework: NO additional Homework McMush revisions are due Monday for those revising the
assignment Do Now:
Students: Please pass your Denatured Enzyme Lab reports in for the teacher to collect. These must all be stapled!
Also, if you have a revised food poster – please pass that in as well.
Today’s Objectives: Describe the difference between structure and function, and
explain how an object’s structure relates to its function Describe the structures and functions of digestive system organs,
and explain how they relate to each other
Bio 9C: Friday, 11.19.10 – MORETTI ABSENTTitle: Digestive System - Structures & Functions
Individual Student Activity Get textbooks for each person from the side
cabinet Read section 38.2 completely and silently
(pgs. 978-985) – it should take about 20 min. to read this thoroughly – there is a lot of new info!
When you have completed reading the section, please ask the teacher for the 38.2 Reading Guide.
Complete questions 1-5 on the reading guide.
Please pass this is in by the end of class.Objectives for Class:
Describe the difference between structure and function, and explain how an object’s structure relates to its function Describe the major structures and functions of all organs in the digestive system
Homework: Complete up to step 3 on the digestion project by
Monday!
Do Now: Which organ is the most confusing to you right
now? Why? If this isn’t addressed by the end of class, ask the question!
Today’s Objectives: Follow carbohydrates, proteins, and lipids through the digestive
system. Decide on the creative form your project will take, and begin writing.

ZOOM IN ON THE SMALL INTESTINE!
Digestive System: Structures
How the Internal Organs Fit Together Image shows major digestive, respiratory, and circulatory system organs
The Project: Follow the journey of some food through the digestive system from the
perspective of the food. Choose a food that contains the following organic compounds:
carbohydrates, protein, and lipids. Trace the path of that food as all of its components are digested.
You will portray this journey in ONE of TWO ways (you choose ONE): Creative Writing: Write a creative story from the perspective of
the food. Describe your journey through the digestive system. Illustrated Storybook: Combine the above option with some
illustrations to trace the path of the food through the digestive system. You might want to describe each major component of the digestive system on a different page (Hint: a great way to do this would be to create the story in PowerPoint, so that each slide is a page).
Your project should illustrate the following big ideas: The relationship between structure and function in the human
digestive system The process of breaking down food into small, building block
molecules The importance of enzymes in metabolism
The Creative Portrayal of the Digestive System Day 1
Digestion Project Overview Begin Digestion Project
Complete Step 1 Be specific when identifying the sources of carbon
compounds in your meal. Complete up to Step 3 for the start of
Monday’s class. Pay close attention to how the carbon compounds are
broken down from the complex polymers to the simplest monomers that are absorbed into the blood stream. How many stages does it take for each to do this?
Objectives for Class: Describe the structures and functions of digestive system organs, and explain how they relate to each other Explain the purpose of the Digestion Project and identify what meal you will use.
Homework: Rough draft of Digestion Project due Wednesday,
12.1.10 at the start of class! Final Drafts are Due Thursday.
Do Now: Take out your digestion project packet Turn to the outline in the Digestion Packet (the end of
Step 2) and wait until the next slide.
Today’s Objectives: Follow carbohydrates, proteins, and lipids through the
digestive system.
Bio 9C: Monday, 11.29.10Title: Digestion Project Work Time
Before moving on from Step 2: Get 3 colored pencils In the chart for Step 2…
Choose one color for carbs. Circle all the chemical digestion that involves carbs in that color.
Choose another color for proteins. Do the same thing.
Choose a 3rd color for lipids. Do the same thing.Next Steps: Organize your notes and story outline Begin writing the story (completed rough draft
due Wednesday)
