Title of Bulletin Board: What Happens To The Turkey We Gobble?

Category: About the Body

Suggested Grade Level: 6-12

Materials: digestive system poster, organ labels, string, letters

Description:

This bulletin board educates students about the digestive system. I used the Thanksgiving turkey we eat to help explain the process of digestion. I made this to help my students easily comprehend what happens to the food once we swallow it. The art teacher drew a larger version of the digestive system onto poster paper. She also had the art classes make turkeys to add to the bulletin board for decoration.

I labeled all of the parts of the digestive system to the side of the poster. I attached string to the organ and the label to help the students easily identify the parts. I attached a small turkey in the mouth, esophagus, stomach, small intestine, and the large intestine to show the order the turkey would travel when inside the body. I also attached a small paragraph next to the mouth, esophagus, stomach, small intestine, and large intestine to explain what specifically happens to the turkey as it breaks down inside the digestive system.

To the side of the diagram, I attached additional facts about the digestive system.

The Digestive Process:
First, your teeth will chop and grind up the turkey into smaller pieces. Saliva is released to help soften the turkey for easier digestion.

When the turkey is swallowed, it will travel down the esophagus to the stomach. The esophagus is a long tube that pushes the turkey down to your stomach.

Then the turkey will enter the stomach. The stomach will churn and mash the food to break it down even smaller. Gastric juices are released from glands in the stomach wall. These juices will help to break down the turkey and kill any bacteria.

Next the turkey enters the small intestine where the nutrients are removed. Then the nutrients enter the bloodstream and travel to body cells where they are used for growth, energy, and repair.

Additional Facts:
The liver produces bile which helps absorb fat in the bloodstream. 2.
The liver is the second largest organ in your body. It has over 500 functions.
The gallbladder is a warehouse for bile. It stores the bile until it is needed.
The esophagus is 10 inches long.
The small intestine is 22 feet long.
The pancreas makes juices that help the body digest fats and protein.
Food can spend up to 4 hours in the small intestine.
The width of the large intestine 3-4 inches and the length is 5 feet.
When we swallow food, a flap of tissue called the epiglottis prevents food from going down our wind pipe
Saliva begins to form in your mouth when you see, smell, or even think about food.

Finally, after the nutrients have been removed from the turkey all that is left is waste. This waste is unable to be digested by the body. The waste will be pushed to the large intestine. Eventually, the remaining waste will leave your body when you go to the bathroom.
