Diffusion and OsmosisStation 1
  • Click here to review the concepts of diffusion
    and osmosis.
  • In your Scientist Notebook, briefly describe the
    processes of osmosis and diffusion. (You may do
    this by words and/or diagrams)
  • Click here to view cells in hypertonic, hypotonic
    and isotonic solutions.
  • In your Scientist Notebook, explain the
    difference between these types of solutions.
    Describe the movement of water in each type of
    solution.

Diffusion and OsmosisStation 2
  • Observing Osmosis in Elodea Cells
  • Click here to link to activity.
  • Follow the directions for this activity and
  • record your observations in your scientist
    notebook. Copy the questions at the end of the
    activity into your Scientist Notebook and record
    your answers.

4
Diffusion and OsmosisStation 3
  • Osmosis and Diffusion Activity
  • Click here for directions.

5
Diffusion and OsmosisStation 4
  • Osmosis and Diffusion Card Sort Activity
  • Cut out the table provided and paste it in your
    Scientist Notebook.
  • Study the cards with pictures of a beaker. The
    circle inside the beaker represents either a cell
    or a dialysis tube.
  • Sort the cards according to the direction of
    movement of materials in the beaker.
  • Record your observations and conclusions on the
    table in your Scientist Notebook .
  • (Observation Table and Cards will be provided)

6
Diffusion and OsmosisAssessment
  • Assessment
  • Follow the directions for
  • Diffusion and Osmosis
  • Check Your Understanding
  • after you have completed all the above activities.

Diffusion and OsmosisTeacher Page
  • Diffusion and Osmosis Card Sort
  • Click here for cards
  • Teacher should copy pictures of beakers and
    laminate them on index cards. Make several sets
    for this station.
  • Click here for observation table
  • Teacher should make one copy of the observation
    table for each student.
  • Diffusion and Osmosis Assessment
  • Teacher should make one copy of the assessment
    for each each student.
