Osmosis and Simple Diffusion Modelling
Use the materials in front of you (the candy) to complete this assignment. The materials will be used to help you answer
all of the questions and recreate different types of solutions that you will illustrate on this worksheet.
1. List the materials being used in this activity: ____________________________________________________________
________________________________________________________________________________________________
2. What is the definition of osmosis?
________________________________________________________________________________________________
3. What is the definition of diffusion?
________________________________________________________________________________________________
On a separate sheet of paper
4. Using the materials in front of you on your desk, create a model of an isotonic solution with your candy materials.
a. Call CPT. Nunez over to check over your candy model. If you get a thumbs up, move onto the next step.
b. Draw a picture of what you have created and label each part of the solution (water molecule, cell
membrane, inside the cell, outside the cell)
c. Describe the picture (define isotonic)
5. Using the materials in front of you on your desk, create a model of a hypotonic solution.
a. Call CPT. Nunez over to check over your candy model. If you get a thumbs up, move onto the next step.
b. Draw a picture of what you have created and label each part of the solution (water molecule, cell
membrane, inside the cell, outside the cell)
c. Describe the picture (define hypotonic)
6. Using the materials in front of you on your desk, create a model of a hypertonic solution.
a. Call CPT. Nunez over to check over your candy model. If you get a thumbs up, move onto the next step.
b. Draw a picture of what you have created and label each part of the solution (water molecule, cell
membrane, inside the cell, outside the cell)
c. Describe the picture (define hypertonic)
FOR EVERY MODEL YOU CREATE WITH YOUR CANDY, CHECK WITH CPT. NUNEZ BEFORE DRAWING IT.
DO NOT EAT THE CANDY.
