Introduction
We know that the human body is comprised of 70-80% water. But, how does it move in
and out of our cells? Is it pushed … pulled …does it flow freely through holes? What
happens when other substances like salt or calcium are present? What would happen if
osmosis stopped? Would we die?
The Task
You’ve been hired to draw a cartoon for a major search engine website “Floogle”.
They’ve told you that in celebration of National Osmosis Week, they want a
cartoon about osmosis.
- Follow this Webquest to learn all you can about osmosis.
- Then, draw your cartoon, correctly applying the process of osmosis in a funny
and entertaining manner, to collect your earnings.
-
EXCEPTIONAL ones will earn extra credit - Good luck.
The Process
Section I: Buckle Up. Here we go …
1.
Sign on to your computer and open Internet Explorer
2.
Choose 3 documents from the following list. (Mark which ones you choose). You
should start by “browsing” all of them. Then choose the ones that make the most
sense to you and use those to complete this portion of the assignment. You may
use as many as you’d like, but the minimum is 3.

3. Take notes (below) on the information. Include any definitions or main points that
you might need to reference later.
Section II: Play that again …
4. Choose 3 flash/streaming videos from the following list. (Mark which ones you choose).
You should start by watching all of them. Then choose the ones that make the most
sense to you and use those to complete this portion of the assignment. You may use as
many as you’d like, but the minimum is 3. .

After watching these, complete the following questions in your own words.
Be Specific!! Don’t use the work “one” - be clear about the term/s you are
talking about or comparing. TYPE your answers in the following spaces!!
1. What is the difference between a solvent and a solute?
A solvent is ________________________________________________
_________________________________________________________
A solute is ________________________________________________
_________________________________________________________
2. What is osmosis?_________________________________________
_________________________________________________________
3. What is diffusion?__________________________________________
________________________________________________________
4. What is the difference between the two…………….?
A. In terms of energy used? ____________________________________
B. In terms of solute and solvent?
C. In terms of whether or not a membrane is needed?

What is a concentration gradient? Give an example and EXPLAIN.

Is water always a solvent? Why or why not? EXPLAIN.
Section III: Show what you know …
Try the 3 interactive activities from the following list. You should start by
trying all of them. Take your time. This third part may take you almost a half
hour to complete – THAT’S OKAY.

Team ____________________
____________________________
Section IV: Bringing it all together …
Once you have completed all of the steps above, you may make a group of 2 people or you
may work alone. You may only choose people who are also done with steps 1-7.
As a team, draw one cartoon about osmosis. The cartoon will include either “witty
dialogue” or a “punch line” that shows understanding of osmosis. You should then include
an explanation of how this applies to osmosis and why it’s funny. Artistic quality and color
do count!!
Do a rough draft of the cartoon below…..
