Design Your Own Experiment
How to Select a Topic Relating to this Concept
If you are interested in osmosis and diffusion, you might study their effects on living organisms or the effects of different solutions on plants or on simple one-celled organisms, such as a paramecium.
Are you interested in rates of diffusion? Try timing how long different solutions take to diffuse throughout water. Or create solutions using different-size molecules and higher and lower concentrations. You might separate solutions and then watch what diffuses through membranes.
Check the For More Information section and talk with your science teacher or school or community media specialist to start gathering information on osmosis questions that interest you.
Steps in the Scientific Method
To do an original experiment, you need to plan carefully and think things through. Otherwise you might not be sure what question...
