Experiment Questions
Osmosis
Osmosis
What is a selectively permeable (semipermeable) membrane?
Allows some molecules through e.g. Visking
tubing, cell membrane, etc.
Osmosis
Describe how you carried out the investigation.
Different solutions / Membrane / Observe /
Time / Control /Measure /safety precaution
Osmosis
How were you able to tell that osmosis had
taken place?
Tissue or membrane swollen / water
movement
Osmosis
State the result(s) of your investigation.
e.g. heavier or swollen after
Osmosis
Describe an investigation that you carried out to
demonstrate osmosis.
Membrane or plant tissue / two solutions
indicated / different concentrations / result
Osmosis
Describe how you demonstrated osmosis in the
laboratory.
Membrane or plant tissue / two solutions
indicated / different concentrations / result
Osmosis
Describe how you demonstrated osmosis as part
of your practical activities.
Apparatus / type of membrane / dilute solution
or (distilled) water / concentrated solution or
tissue / time period / how change was
observed / control
Osmosis
What did you use as the selectively permeable
membrane in your investigation of osmosis?
Visking tubing or named plant tissue
