contains a chemical to begin the process
of digestion.

• Follow-up to Activity for digestive system!
– Place small piece of chicken meat and bone
into a jar with vinegar.
– Take a similar size of meat and cut with a knife
into many pieces and place in another jaw

– Add vinegar and cap jar and set aside until you
reach the digestion system / digestive juices.

• How is the piece of chicken looking?
– The meat should be broken down. The vinegar
is acidic (pH of 2.4-3.4).
– The pH of your stomach is about 1 (Acidic)
HCL
– Your small intestine is alkaline (pH 7.1) which is
better for the digestive enzymes.

• Activity! Digestion Simulation
– In the following simulation, we will be placing
food into an assembly line that breaks apart
instead of put together.
– The class will be divided into various stations /
organs of the digestive system.
– Each station will either be mechanical
digestion, chemical digestion, or both.
– Students will add “chemicals” with spray
bottles or mechanically shake / wave the bag
and then pass it to the next group.

• The GI Tract begins in the mouth where food is
broken down mechanically and chemically. The
food passes through the pharynx and is moved
down the esophagus to the stomach. Acid and
movement break the food down further.
Chemicals are produced and then released in
the liver, gall bladder, and pancreas to the small
intestine. Food is broken up further in the
intestine and nutrients are absorbed. Water is
absorbed in the large intestine and vitamins
made. The waste is collects in the rectum until
disposal.
