2. Where We’re Going Next 1.Brief review (2 days) of Digestive System (recall 9 th grade digestion project…) 2.Small-group projects/presentations exploring an aspect of human body systems in more depth 3.Larger up-coming projects:  Team project: Develop and present a lesson combining food, cooking, and an aspect of human health Most likely for middle school children at Margaret Fuller House  Individual final project on Human Body Systems & Food Story, picture book, or pamphlet… will allow creativity!

4.  Break down food into small enough pieces that it can be absorbed into the bloodstream  Mechanical/physical digestion: breaks food chunks into smaller pieces Ex: bagel  bagel crumbs Ex: bagel  bagel crumbs  Chemical digestion: breaks large molecules into small molecules Ex: starch  glucose Ex: starch  glucose  Release waste/un-digestible materials Functions of the Digestive System

5. Today’s Agenda & Goals 1.Work in groups to take notes on an assigned section of the digestive system. Group 1: BSCS book, Mouth – Stomach Group 2: BSCS book, Small Intestine – Anus Group 3: Dragonfly book, Mouth – Stomach Group 4: Dragonfly book, Small Intestine – Anus 2.Jigsaw – Split into new groups to share the info you’ve found. Goals:  Extract info from textbooks and compare sources  Follow the path of food molecules through the entire digestive system

6.  Homework:  Mini-Reflection on Digestive System – See assignment sheet for the specific prompts – but due FRIDAY not Thursday!  Do Now:  Make sure you have nothing in your mouth. If you’ve just eaten/drank something other than water, go get a quick drink.  Take a very small bite of cracker and gently chew it, keeping it near the front of your tongue. Squish it around in your mouth for a minute or two (again, keep it near the front of your tongue). Pay attention to the taste – does it change over time?  Today’s Objective:  Identify the structures and functions of the major organs in the digestive system  Trace the path of food molecules through the digestive system EPICS Food: Tuesday, 2.9.10 Digestive System: Structure & Functions

8.  Homework:  Mini-Reflection on Digestive System – See assignment sheet for the specific prompts –due TOMORROW  Do Now:  Get out your Digestive System chart and prepare to journey into the colon…  Today’s Objectives:  Identify the structures and functions of the major organs in the digestive system  Trace the path of food molecules through the digestive system  Start the Food & Human Health Mini-Projects EPICS Food: Thursday, 2.11.10 Digestive System: Structure & Functions
