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: Digestion Review Questions Pass Revised McMush Lab Reports

Do Now: Describe the structure and function of the

following objects

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,

Bio 9C: Monday, 11.22.10Title: Digestive System: Structures & Functions

Debrief Do Now:

Function: Crush thingsRelate structure to function: Hinges allow it to

open to receive things & close to crush them

Metal provides hard crushing surface

Ridges prevent things from slipping out

Similar digestive organ:

Mouth

Function: Hold/contain/store thingsRelate structure to function: Sack-like shape

with space inside to hold stuff

Drawstring opening can open to receive things, and close so they don’t fall out

Similar digestive organ:

Stomach

Function: Dry things by absorbing waterRelate structure to function: Cotton material is

very absorbent Tiny strings on

surface provide more space for absorbing stuff

Similar digestive organ:

Small intestine

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.

The Creative Portrayal of the Digestive System

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)
