This WebQuest covers the following Utah State Core Standards for 7th Grade:
STANDARD III: Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.
Objective 1: Observe and describe cellular structures and functions.
d. Model the cell processes of diffusion and osmosis and relate this motion to the
motion of particles.
Your cells are very complex. They must operate efficiently or you will know they aren’t! You’re going to explore how cells function. You will learn how water and chemicals get into and out of the cell. (Note: if you don't have a copy of the worksheet, click here.)
- You will visit three websites giving a summary of diffusion and osmosis.
- You will visit three interactive websites showing movies about diffusion and osmosis. After watching these, you will answer questions comparing and contrasting osmosis and diffusion.
- You will visit three websites with interactive osmosis and diffusion activities where you will practice applying your knowledge.
- After you have completed the WebQuest, you and a partner will draw one cartoon that shows how diffusion works and one cartoon showing how osmosis works. The cartoon will include either "witty dialogue" or a "punchline" that correctly demonstrates and understanding of diffusion and osmosis.Resources

You have completed your introduction to two important cell functions - diffusion and osmosis. Here's what you should now understand...
- a definition of diffusion.
- how diffusion works.
- why diffusion is important to cell function.
- a definition of osmosis.
- how osmosis works.
- why osmosis is important to cell function.
You will now begin conducting experiments and seeing diffusion and osmosis in action!
