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.

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)

  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.
