Refer to page 16 and 19 of your science text book to complete the
activity below.
1.
Use these words to complete the passage;
Saliva
Esophagus
Digestion
Mouth
Stomach
Gastric juices
Food provides the body with the energy it requires. The nutrients the
body needs comes from the food and drink we consume. This process
of change is known as
_________________________.
When food enters the ______________________, fluids start
changing the starches into sugar that the body can digest with the
help of the ______________________.
The food continues down the ____________________. Muscular
movements squeeze and push it down to the
_______________________.
Once in the stomach, some food remains here for awhile. Other food
particles are further broken down by _____________________.
These juices are made up of water and chemicals that soften the food
and kill the bacteria. This process takes approximately 3 to 4 hours to
occur.

Exploration: Investigate What Happens in your Mouth and
Stomach.
1.
Chew a cracker just a little and then hold it in your mouth for two
or three minutes without swallowing. What happens to the cracker?
What happens to the taste?
2.
Break several crackers into bite-size pieces, put them into the
cups and stir. Add water at a time until it barely covers the crackers.
What happens to the crackers as you stir?
_____________________________________________________
_____________________________________________________
3.
Put the cracker and water mixture in the plastic bag. Gently
remove the air from the bag and close it tightly. Squeeze it between
your fingers. Can you still feel pieces of crackers? What could you do
to make the mixture more soupy?
_____________________________________________________
_____________________________________________________
Interpret Your Results
1.
How did the cracker taste by the time you swallowed it? What
happened to cause the change? How did the texture of the cracker
change?

2.
How was stirring and adding water to the crackers in the cup like
what happens in your mouth?
_____________________________________________________
_____________________________________________________
3.
What happened to the cracker and water mixture in the plastic
bag? How is that similar to what happens inside your stomach?

How Long is the Digestive System?
Use four different colours of yarn to represent the length of the
digestive system. Each colour should represent an organ of the system.
Measure and cut the length of each organ below:
Esophagus 25cm
Stomach 20 cm
Small Intestine 700 cm
Large Intestine 150 cm
Different thicknesses of yarn should be used for large and small
intestines.
1. Tie each piece of yarn together. What is the total length of the
digestive system? Show your workings.
