Osmosis Jones and
your egg
experiment
What is the definition of osmosis?
• The diffusion of water (from a high concentration to a low
concentration) through a selectively permeable membrane.
• Did you get it right?
Speaking of “OSMOSIS”
• Remember our egg?
• Watch this video: Diffusion and Osmosis for
Egg project 6315 or 1000631501
• So, let’s talk about that egg project:
• Hypotonic (low)
•
Hypertonic(high)
Egg has squirting power due to all the H2O contained inside the
cell membrane (CAUSING HIGH PRESSURE )
Think of it as a balloon that is over filled and very fragile!

Remember when you used a pin to poke a hole in your egg? It did one of three things:
1. Had squirting ---like a “spraying fountain” power
or
2. Burst like an egg explosion
or
3. Squirted and then burst!
This was a result of the excess amount of the water that had diffused inside the membrane
due to the less amount of water contained in the egg after being in the syrup (where the
sugar was in more concentration than water so the water had left the egg to go out into the
more sugar particle area).
Remember, diffusion occurs when the higher concentration exists so the particles of the
higher concentration will go out where there is less until there seems to be a balance of
those particle (solutions)
(balance)
hypertonic
hypotonic
What is the difference between
osmosis and diffusion?
• The concept is exactly the same . . . . Higher
concentration which moves to an area of
lower concentration through a semipermeable membrane. . . .except. . . . Using
• WATER!
Here are the organs of the ____?_____
system:
•
•
•
•
•
•
•
•
•
Lymphatic vessels
Lymph nodes
Tonsils and adenoids
Thymus gland
Peyer’s patch
Spleen
WBC
Bone marrow- wbc, rbc, platelets
Lymph fluid
• So what are these organs a part of----??????
The immune system!!
What are all the parts of the immune
system for?
• To protect your body from germ invaders
When germs enter the body your
immune system will attack and kill!!
Does your immune system always win?
•NOPE!!!!
How do you help your immune system
to you?
• 1. Get the right amount of sleep 8-9 hours for your
age.
• 2. Eat fruits, veggies, proteins like fish,---very light on
the sweets. Garlic and onions are great for your
immune system.
• 3. Take a multivitamin each day.
• 4. Get exercise—about one hour a day is good. Work
up slowly if you are just beginning.
• 5. Keep your stress level down—stress is very hard on
your immune system if you do not control it. Yoga and
listening to quiet relaxing music is good to help calm
you.
Why did we watch Osmosis?
• To look at diffusion
• And
• To introduce one of the
• body systems.
• Hopefully it helped you
• to understand some of the
• workings of that system.
The Cast of Osmosis Jones
Osmosis Jones!!
Chris Rock
Thrax!
Laurence
Fishburn
“Drix” is David Hyde Pierce
Mayor Phlegm-William Shatner
“Leah” is played by Brandy Norwood
“Kidney Rock” played by Kid Rock
“Tom Colonic” played by Ron Howard
So---Osmosis Jones. . . .
• Fun show based on some facts about your
body and how some body systems function.
• Some things were exaggerated and Thrax was
a made-up germ
• Take care of your body so you do NOT become
unhealthy like Frank did.
• Hope you enjoyed the learning on Osmosis 
