AfL: Passive Transport Assessment

The cell membrane of plants and animals allows for the selective transport of materials into and out of the cell. The methods by which substances are transported across the membrane are either passive (i.e. requiring no input of energy) or active (i.e. requiring the input of energy.)

Water moves across the cell membrane in a passive manner to establish a state of equilibrium. In this assessment, plan an investigation to demonstrate the movement of water into and out of plant and animal cells.

Instructions

Task is to plan and conduct a simple experiment to demonstrate passive transport using common household items found As an inquiry-based activity, design your own experiment, including the following:

Determine an appropriate 'Testable Question'.
Propose a reasonable hypothesis based on 'Testable Question'.
Develop a procedure based on 'Testable Question'.

Step 1: Planning Your Experiment

Determine the testable question you wish to investigate. If have trouble thinking of a testable question, review the simulation for ideas. Ensure that testable question can be answered using quantifiable data and not simply qualitative observations.
Once decided on testable question, propose a reasonable hypothesis for the experiment plan to conduct. hypothesis should explain how the change in independent variable will affect dependent variable. As previously stated, the change in your dependent variable should be quantifiable.
Develop the procedure for the experiment intend to conduct in order to test hypothesis. procedure should be specific and detailed, allowing another scientist to recreate experiment using the exact steps you used in your investigation. Write the steps of the procedure in the past tense.
Upload your testable question, hypothesis, and planned procedure to the AfL: Passive Transport - Procedure Dropbox. Your teacher will review your work to ensure your experimental plan is correct.

Important

It is strongly recommend that you submit Step 1 of this activity before conducting your experiment and completing your report. The feedback you receive from your teacher will help ensure that the plan for experiment is in line with the objective for this assessment.

Note

Refer to the "Planning an Investigation" page in the Scientific Skills and Formatting module to help you plan your test.

Step 2: Conducting Your Experiment

Apply any feedback from your teacher to your planned experiment.
Conduct your experiment to test your hypothesis.

Step 3: Communicating Your Results

Once you have completed your test(s), communicate your results in a lab report.
Your lab report should include the following sections: testable question, hypothesis, materials, procedure (including your identified variables), observations, results, discussion, and conclusion.
