Digestion-Small Intestine Part 1

Part 1
We are still going strong with the digestive system. Today we looked at the role and function of the digestive system. We discussed how once the bolus leaves the stomach and enters the small intestine, it is the the consistency of a smoothy, therefore easier for the the blood stream to absorb nutrients through the villi of the small intestine (I KNOW it is overly simplified). We then did the following activity (from http://kids.niehs.nih.gov/explore/pollute/water2_digestive_system.htm) in teams of 2,  to help them visualize the transport of nutrients across the small intestine wall:

Water -- the great dissolver


They were able to "see" that nutrients without the assistance of water just stay there. Once we added the water it was very easy to see how the nutrients left the small intestine and are transported into the blood (the inner cup). They were amazed!

Here is a picture of before we added water and after we added water.
We even added capillaries!


Tomorrow we will be doing another activity that helps to explain the breakdown of fats and proteins in the small intestine with the assistance of the liver and pancreas. Will post those pictures too.

Children...

By Dorothy Law Nolte, Ph.D.

If children live with criticism, they learn to condemn.
If children live with hostility, they learn to fight.
If children live with fear, they learn to be apprehensive.
If children live with pity, they learn to feel sorry for themselves.
If children live with ridicule, they learn to feel shy.
If children live with jealousy, they learn to feel envy.
If children live with shame, they learn to feel guilty.
If children live with encouragement, they learn confidence.
If children live with tolerance, they learn patience.
If children live with praise, they learn appreciation.
If children live with acceptance, they learn to love.
If children live with approval, they learn to like themselves.
If children live with recognition, they learn it is good to have a goal.
If children live with sharing, they learn generosity.
If children live with honesty, they learn truthfulness.
If children live with fairness, they learn justice.
If children live with kindness and consideration, they learn respect.
If children live with security, they learn to have faith in themselves and in those about them.
If children live with friendliness, they learn the world is a nice place in which to live.
